Title: Systems and methods of linking gaming stations

Description:
FIELD 
     Embodiments of the present disclosure relate to wagering games having at least one associated payout (e.g., jackpot or progressive jackpot) and a payout determination device (e.g., a spin wheel). 
     BACKGROUND 
     The use of progressive jackpots in casino games is well known in the art. Wagering games employing progressive jackpots conventionally include an amount of money to be won if a predetermined event or condition to trigger a payout from a progressive jackpot occurs in a wagering game. The amount of money to be won is traditionally displayed on an incrementing jackpot meter or display. The predetermined event or condition may be time-based, game-based, randomly determined or otherwise. For each wagering game (e.g., at the beginning or end of the wagering game, for each round of the wagering game played, etc.) a portion of the wager may be added to the progressive jackpot. This wager is typically an optional side bet wager that is fixed in amount and is made on an electronic coin spot sensor. As a result, the amount of money to be won with the progressive jackpot may increase for each wagering game played. The increases may be shown on the jackpot meter or display. 
     Multiple gaming stations of the same type (e.g., multiple gaming tables, multiple slot machines, etc.) that offer the same wagering game are sometimes linked to a common progressive jackpot. The common progressive jackpot may cause the amount of money to be won with the progressive jackpot to increase more quickly, which may result in higher progressive jackpots depending upon the probability of occurrence of a jackpot trigger. Higher progressive jackpots may add appeal to a wagering game, and may result in more wagering games played, or rounds of wagering games played. 
     Operating a progressive jackpot system including multiple gaming stations that are all configured to administer the same wagering game may be relatively simple because the probability of the jackpot trigger at each of the gaming stations is the same. For example, multiple blackjack tables may each be linked to the same progressive jackpot, and each contributes a portion of its side bets to the same progressive jackpot. A player at any of the blackjack tables may win the progressive jackpot responsive to achieving a jackpot trigger such as a premium hand (such as five (5) Ace of Spades, for example) at their blackjack table. 
     Linking multiple gaming stations that host different wagering games may further accelerate an increase in the progressive jackpot in a given amount of time. Some conventional progressive jackpot systems link multiple gaming stations that are configured to host different wagering games with different probabilities of jackpot triggers. One such example is described in U.S. Pat. No. 7,297,059 to Vancura et al., which describes a system that determines a fractional portion of a progressive jackpot to be awarded when a jackpot trigger occurs. The fractional portion that is awarded is based on the size of a wager; however, the probability of winning the progressive jackpot may be different at different gaming stations. 
     Another example of a conventional progressive jackpot system that links multiple gaming stations configured to host different wagering games with different jackpot win probabilities is described in U.S. Pat. No. 5,855,515 to Pease et al., which describes randomly selecting a gaming station to participate in the progressive jackpot. If a group that the selected gaming station belongs to has contributed a threshold amount to the progressive jackpot, then a random number generator is used to determine if a player at the selected gaming station wins the progressive jackpot. The described system, therefore, removes the jackpot trigger element from the progressive jackpot system. 
     BRIEF SUMMARY 
     Embodiments of the present disclosure include systems and methods of operating a progressive wagering game such that the probability that a current round of game play qualifies for winning a payout (e.g., a major progressive jackpot) is equal among all gaming stations despite the gaming stations administering wagering games having game jackpot trigger probabilities that are dissimilar. Furthermore, the value of the payout may be determined by one or more payout determination devices (e.g., a spin wheel). 
     In some embodiments, the present disclosure comprises a progressive jackpot system. The progressive jackpot system includes at least one processor programmed to link at least two gaming stations to a progressive jackpot. The at least two gaming stations may be configured to administer at least two different wagering games that have different jackpot trigger probabilities for achieving a jackpot trigger for the major progressive jackpot. The at least one processor may be further programmed to normalize a major jackpot winning probability based, at least in part, on the different jackpot trigger probabilities such that the major jackpot winning probability for players of the at least two different wagering games is substantially the same. The jackpot trigger of at least one of the two gaming stations may be associated with a prize of a payout determination device triggered in response to the occurrence of a particular wagering game outcome. 
     In other embodiments, the present disclosure comprises a progressive jackpot system. The progressive jackpot system comprises at least one processor programmed to manage a major progressive jackpot for a plurality of linked gaming stations administering different wagering games, having different highest ranking hand win probabilities, and normalize a major jackpot winning probability to be substantially the same probability for each of the different wagering games to win the major progressive jackpot even though the different wagering games have jackpot triggers that have different jackpot trigger probabilities from each other. At least one of the jackpot triggers of the different wagering games may be associated with a prize segment of a spin wheel spun in response to the occurrence of a particular wagering game outcome. 
     In other embodiments, the present disclosure comprises a method for operating a jackpot system. The method comprises providing a first gaming station administering a first wagering game with a first jackpot trigger probability of achieving a jackpot trigger, wherein the first jackpot trigger is associated with a prize segment of a spin wheel spun in response to the occurrence of a particular wagering game outcome, and providing a second gaming station administering a second wagering game with a second jackpot trigger probability of achieving a jackpot trigger, the first wagering game and the second wagering game being different. For example, a highest ranking hand of the first wagering game at the first gaming station and a highest ranking hand of the second wagering game at the second gaming station have different winning probabilities. The method further comprises assigning a first eligibility probability to the first wagering game for the first gaming station to be eligible to participate in a jackpot, assigning a second eligibility probability to the second wagering game for the second gaming station to be eligible to participate in the jackpot, and determining whether at least one of the first gaming station and the second gaming station is eligible to participate in the jackpot based, at least in part, on the corresponding first eligibility probability and the second eligibility probability.

     DETAILED DESCRIPTION 
     The illustrations presented herein are not meant to be actual views of any particular act in a method of administering a wagering game, apparatus for use in administering a wagering game, or component thereof, but are merely idealized representations employed to describe illustrative embodiments. Thus, the drawings are not necessarily to scale. Additionally, elements common between figures may retain the same or similar numerical designation. Elements with the same number, but including a different alphabet character as a suffix should be considered as multiple instantiations of substantially similar elements and may be referred generically without an alphabet character suffix. For example, elements  100   a ,  100   b , and  100   c , may be a device that is instantiated three times and generically referred to herein as element  100 . 
     The terms “gaming,” “gambling,” or the like, refer to activities, games, sessions, rounds, hands, rolls, operations, and other events related to wagering games such as web-based games, casino games, card games, dice games, and other games the outcome of which is at least partially based on one or more random events (“chance” or “chances”), and on which wagers may be placed by a player. In addition, the words “wager,” “bet,” “bid,” or the like, refer to any type of wager, bet, or gaming venture that is placed on random events, whether of monetary or non-monetary value. Points, credits, and other items of value may be purchased, earned, or otherwise issued prior to beginning the wagering game. In some embodiments, purchased points, credits, or other items of value may have an exchange rate that is not one-to-one to the currency used by the user. For example, a wager may include money, points, credits, symbols, or other items that may have some value related to a wagering game. Wagers may be placed in wagering games that involve the risk of real-world monetary value for the potential of payouts with real-world monetary value (e.g., the “play-for-pay,” “player-pooled progressive,” and “dividend refund” configurations, which are described in more detail below) or in wagering games that involve no real-world monetary risks for the player (e.g., the “play-for-fun” and “social play-for-fun” configurations, which are also described in more detail below). 
     As used herein, the term “wager” includes any form of wagering value, including money, casino chips, other physical means for payment, and online or remote electronic authorization of a wager in any acceptable form to the casino or online or virtual game host. Also included are physical representations of money (e.g., casino chips) at a local gaming table  900 , or  1000  (see  FIGS. 9 and 10 ), or electronic authorizations of a transfer of money or digital representations of money (e.g., digital representations of bills or coins, digital representations of chips, numerical quantities of money, numerical quantities of points, or numerical quantities of credits) at a local or remote electronic gaming device  800 ,  900 ,  1000 ,  1120 , or  1240  (see  FIGS. 8 through 12 ). In the “play-for-fun” and “social play-for-fun” configurations, a “wager” may not have a cash value (i.e., a real-world monetary value), or may have a value that permits redemption of the non-monetary payouts for prizes, privileges and game play advantages, such as an award of extra non-monetary chips, an award of a time compression or an award of a special game piece or special game element. 
     For the purposes of this description, it will be understood that when an action related to accepting wagers, making payouts, dealing cards, selecting cards, or other actions associated with a player or a dealer are described, the description includes a player or a dealer taking the action, the results of the action on a live or virtual table or display, and, if applicable, the reception or detection of such an action in an electronic form where player and dealer choices, selections, or other actions may be received at an electronic interface. This further includes the results of a virtual dealer and virtual players, where the actions described are actually generated by a computer (typically associated with an online game). By way of a further example, if dealing of a card is described herein, the description includes (but is not limited to) the following: the dealing of a card by a dealer from a deck, shuffler, a shoe, or other card source and the reception or placement of the card at a table location associated with a player or reception directly by a player; the generation and transmission of an electronic indication or representation of a card from a game play source or server to an electronic receiver, where the receiver may be at a table (using virtual cards) including players and/or virtual players and/or a dealer or virtual dealer, at a public display in a casino, at a remote location (e.g., using online or Internet game play), or at other locations. Also included is the representation of a card on a display or displays, and, if applicable to the action described, an electronic reception of an indication that the card has been received, selected, or otherwise interacted with at a location associated with a player, or, associated with a virtual player. In addition, dealing of a card may refer to revealing a representation of a card on a scratch-off card (also referred to as “scratchers”). 
     It is to be understood that in some embodiments, when a dealer hand is dealt or the dealer otherwise takes action, it is not necessary to display a dealer or a dealer representation on a player display. For example, if the player hand must be compared to a dealer hand to determine if the hand wins, it is only necessary to display a dealer hand, not an actual dealer or representation of a dealer. 
     In addition, it is noted that the embodiments may be described in terms of a process that is depicted as a flowchart, a flow diagram, a structure diagram, or a block diagram. Although a flowchart may describe operational acts as a sequential process, many of these acts can be performed in another sequence, in parallel, or substantially concurrently. In addition, the order of the acts may be re-arranged. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc. Furthermore, the methods disclosed herein may be implemented in hardware, software, or both. If implemented in software, the functions may be stored or transmitted as one or more instructions (e.g., software code) on a computer-readable medium. Computer-readable media includes both computer storage media and communication media including any medium that facilitates transfer of a computer program from one place to another. 
     It should be understood that any reference to an element herein using a designation such as “first,” “second,” and so forth does not limit the quantity or order of those elements, unless such limitation is explicitly stated. Rather, these designations may be used herein as a convenient method of distinguishing between two or more elements or instances of an element. Thus, a reference to first and second elements does not mean that only two elements may be employed there or that the first element must precede the second element in some manner. Also, unless stated otherwise a set of elements may comprise one or more elements. 
     The term “dealer,” as used herein, refers to any person or thing that administers a wagering game in any capacity, and should not be understood to be limited to persons who deal cards to players. For example, the “dealer” may comprise a processor programmed with a set of game rules and a display for displaying a dealer hand of cards, rather than a display of a dealer or representation of a dealer. Likewise, the term “dealer interface” should be understood to include an interface configured for use by any person who administers a wagering game in any capacity. The term “dealer,” in some embodiments, may also refer to a computerized dealer which administers a wagering game autonomously, partially autonomously, or by initiation of an on-site or remote human operator. A dealer may also be referred to as an assistant or an attendant. 
     Embodiments of the present disclosure may include a progressive jackpot system that enables players of different wagering games to have substantially the same odds of winning a major progressive jackpot, regardless of the odds of achieving a winning outcome in a particular wagering game. Wagering games having winning outcomes that are based on dissimilar probabilities may be linked to the same major jackpot, and an assigned probability of a particular type of wagering game being selected to qualify for major progressive jackpot play is used to normalize the jackpot winning probability across all wagering games linked to the major progressive jackpot. 
       FIG. 1  is a simplified block diagram of a progressive jackpot system  100  according to an embodiment of the present disclosure. The progressive jackpot system  100  may include a plurality of gaming stations  102 A 1 ,  102 A 2 , . . .  102 A N ,  102 B 1 ,  102 B 2 , . . .  102 B N ,  102 C 1 ,  102 C 2 , . . .  102 C N  (sometimes referred to generally herein collectively as “gaming stations  102 ,” and individually as “gaming station  102 ”). The common use of subscript “N” among the different groups does not mean that each group must have the same number of gaming stations  102 . The subscript “N” is merely used as a convenient way to indicate that each group of gaming stations  102  may have any number of gaming stations  102 . 
     The gaming stations  102  may include, but are not limited to, gaming tables, gaming machines, electronic gaming devices, gaming cabinets, personal computers, laptop computers, tablet computers, smart phones, and other gaming apparatuses that are configured to administer various wagering games. Each gaming station may be used to administer a wagering game played by a single player, or by multiple players. When the gaming station is a conventional gaming table, multiple players typically participate simultaneously in playing a casino game such as THREE CARD POKER®, ULTIMATE TEXAS HOLD &#39;EM®, or other community card game. Other gaming stations may be electronic gaming machines configured for single player play. Yet other gaming stations may be personal computers or mobile devices in the case of on online game play, or multiple player systems such as an all-electronic multiple player platform or a hybrid platform such as one that utilizes physical cards and credit wagering, virtual cards and physical chips, or combinations thereof. 
     The gaming stations  102  may be configured to interact with a player or multiple players of a wagering game during game play. The wagering games may include card games, dice games, and other games of chance in which a wager may be placed. Examples of wagering games may include, but are not limited to, poker variations, blackjack, bingo, keno, craps, slots, pachinko, baccarat, roulette, betting on sporting events, and other wagering games. The different wagering games may have different rules, win probabilities, betting amounts, pay tables, etc. 
     Each of the gaming stations  102  may be linked to a major progressive jackpot  108 . The major progressive jackpot  108  includes a common progressive jackpot for linked gaming stations  102  that are configured to administer different wagering games. For example, a first group of gaming stations  102 A 1 ,  102 A 2 , . . .  102 A N  may be configured to administer a first wagering game, a second group of gaming stations  102 B 1 ,  102 B 2 , . . .  102 B N  may be configured to administer a second wagering game, and a third group of gaming stations  102 C 1 ,  102 C 2 , . . .  102 C N  may be configured to administer a third wagering game. 
     In some embodiments, each of the gaming stations  102  may be linked to a mega progressive jackpot  111 . The mega progressive jackpot  111  includes a common progressive jackpot for linked gaming stations  102  that are configured to administer different wagering games. In some embodiments, the common progressive jackpot of the mega progressive jackpot  111  may include more linked gaming stations  102  than the major progressive jackpot  108 . The mega progressive jackpot  111  may have a smaller probability of being won than the major progressive jackpot  108 . The mega progressive jackpot  111  may have a higher maximum amount than the major progressive jackpot  108 . The mega progressive jackpot  111  may operate in manner similar to the major progressive jackpot  108 , and for purposes of the present disclosure, in order to avoid redundancy, the disclosure may focus on the major progressive jackpot  108 . However, it is understood that the mega progressive jackpot  111  may be included and utilized in any scenario where the major progressive jackpot  108  is included and utilized and may be used in addition to the major progressive jackpot  108 . 
     Other jackpots may also be offered. For example, a minor progressive jackpot  110  may be offered. In some embodiments, the gaming stations  102  administering the same wagering games may be linked to participate in a minor progressive jackpot  110 , as well as the major progressive jackpot  108 . For example, the first group of gaming stations  102 A 1 ,  102 A 2 , . . .  102 A N  may linked to a first minor progressive jackpot  110 A, in addition to the major progressive jackpot  108 . The second group of gaming stations  102 B 1 ,  102 B 2 , . . .  102 B N  may be linked to a second minor progressive jackpot  110 B and to the major progressive jackpot  108 . The third group of gaming stations  102 C 1 ,  102 C 2 , . . .  102 C N  may be linked to a third minor progressive jackpot  110 C and to the major progressive jackpot  108 . Other progressive jackpots may also be offered (e.g., individual gaming station progressive jackpots), as well as additional major and minor progressive jackpots of varying sizes. For example, multiple major progressive jackpots may be offered that encompass different numbers of gaming stations  102  even if the different major progressive jackpots overlap for some of the gaming stations  102 . As a result of generally being linked to a higher number of gaming stations  102 , the amount to be won in the major progressive jackpot  108  may often be higher than the amounts to be won in the minor progressive jackpots  110  and the other progressive jackpots. Jackpots may have a jackpot cycle and the jackpot amount can grow to a theoretical maximum amount at the time the jackpot hits. By adding more gaming stations  102  to a jackpot system, the jackpot reaches its theoretical maximum sooner and more jackpot cycles are completed in a unit of time, attracting more players to play the jackpot game. In some embodiments, there may be situations in which the amount to be won in the major progressive jackpot  108  may be less than the amounts to be won in the minor progressive jackpots  110  and other progressive jackpots. 
     A player may win the major progressive jackpot  108  responsive to the occurrence of a jackpot trigger. In other words, the jackpot trigger is a predetermined occurrence that may result in a player winning the major progressive jackpot  108 . By way of non-limiting example, the jackpot trigger may be a predetermined winning game outcome (e.g., a particular card combination, reel position, etc.). The winning game outcome may depend on the type of wagering game and its associated rules. The jackpot trigger may be selected as the winning game outcome that is associated with the top prize for the wagering game; however, that does not necessarily have to be the case. The winning game outcome associated with the top prize for the wagering game is normally used because it typically has the lowest probability of the various winning game outcomes. One example of a hand that is commonly used as a jackpot trigger that pays the top prize for a game based on 5-card poker hand combinations is a Royal Flush. In some embodiments, there may be multiple jackpot triggers that have different results. For example, a first jackpot trigger may result in winning the entirety of the major progressive jackpot  108 , and a second jackpot trigger may result in winning the entirety of the minor progressive jackpot  110 . As another example, a first jackpot trigger may win 100% of a major jackpot and a second jackpot trigger may win 25% of the same major jackpot. Some jackpot triggers may result in winning a portion of either the major progressive jackpot  108  and/or the minor progressive jackpot  110 . 
     The probability of achieving a particular winning game outcome may depend on the type of wagering game and its associated rules. Because the gaming stations  102  may not all administer the same wagering game, the different wagering games may have winning game outcomes that are based on dissimilar winning game outcome probabilities. As a result, the probabilities of the jackpot triggers may be different from gaming station  102 A to gaming station  102 B. For example, referring to  FIG. 1 , the first wagering game administered by each of the first group of gaming stations  102 A 1 ,  102 A 2 , . . .  102 A N  may have a first jackpot trigger probability P(JackpotTriggerA). The second group of gaming stations  102 B 1 ,  102 B 2 , . . .  102 B N  may have a second jackpot trigger probability P(JackpotTriggerB). The third group of gaming stations  102 C 1 ,  102 C 2 , . . .  102 C N  may have a third jackpot trigger probability P(JackpotTriggerC). The jackpot trigger probabilities refer to the winning game outcome(s) associated with the particular wagering game that is used to trigger a first (minor) jackpot winning event. Because the wagering games are different, the jackpot trigger probabilities may also be different. For example:
 
 P (JackpotTrigger A )=1/ X;  
 
 P (JackpotTrigger B )=1/ Y ; and
 
 P (JackpotTrigger C )=1/ Z,  
 
where “X” is the average number of rounds of the first wagering game for its jackpot trigger to occur, “Y” is the average number of rounds of the second wagering game for its jackpot trigger to occur, and “Z” is the average number of rounds of the third wagering game for its jackpot trigger to occur.
 
     The probability of winning the major progressive jackpot  108  is referred to as the major jackpot winning probability P(MajorWin). The progressive jackpot system  100  may be configured to normalize the major jackpot winning probabilities for the different types of wagering games that are linked to the same major progressive jackpot  108 . For example, the progressive jackpot system  100  may be configured such that the players of the progressive jackpot system  100  may have substantially the same odds of winning the major progressive jackpot prize, regardless of the jackpot trigger probability P(JackpotTrigger) of the particular wagering game. Thus, P(MajorWinA), P(MajorWinB), and P(MajorWinC), may be substantially equal even though P(JackpotTriggerA), P(JackpotTriggerB), and P(JackpotTriggerC) may be dissimilar. In other words, after normalization:
 
 P (MajorWin A )≈ P (MajorWin B )≈ P (MajorWin C ).
 
     In some embodiments, the progressive jackpot system  100  may assign each gaming station  102  to have an eligibility probability P(Eligible) for participating in the major progressive jackpot  108 . This eligibility probability P(Eligible) is a probability for each gaming station  102  to be eligible for winning the major progressive jackpot  108  during game play. In other words, the gaming station  102  may be eligible for winning the major progressive jackpot  108  during some (but not all) opportunities during game play according to its eligibility probability P(Eligible). As a result, a player may only win the major progressive jackpot  108  when the jackpot trigger occurs and when the gaming station  102  is eligible. Thus, even if the jackpot trigger is achieved when the gaming station  102  is not eligible, the major progressive jackpot  108  may not be won. In some embodiments, the same jackpot trigger wins the first minor jackpot and the major jackpot, so when a game round is not eligible for major jackpot play and the player holds a jackpot triggering hand, the player wins the minor jackpot instead of the major jackpot. In other embodiments, the jackpot triggers to win the entire jackpots are different. In some embodiments, there are multiple jackpot triggers, with one premium hand that wins 100% of the jackpot, and other hands that win either a percentage of the jackpot, an odds payout or a fixed amount. 
     The probability for each player winning the major progressive jackpot  108  may be normalized by adjusting an eligibility probability P(Eligible) for each gaming station  102 . The probabilities for winning the major progressive jackpot  108  may be:
 
 P (MajorWin A )= P (JackpotTrigger A )* P (Eligible A );
 
 P (MajorWin B )= P (JackpotTrigger B )* P (Eligible B ); and
 
 P (MajorWin C )= P (JackpotTrigger C )* P (Eligible C ).
 
     For the major jackpot winning probabilities P(MajorWin) to be substantially equal among the different gaming stations  102 , the eligibility probabilities P(Eligible) among the different gaming stations  102  may be dissimilar. For example, P(EligibleA), P(EligibleB), and P(EligibleC) may be dissimilar. 
     The eligibility probability P(Eligible) of a particular gaming station  102  may be proportional to the inverse of the jackpot trigger probability P(JackpotTrigger) for that particular gaming station  102 . For example, the eligibility probability P(Eligible) may be determined by dividing the major jackpot winning probability P(MajorWin) by the jackpot trigger probability P(Eligible) of the wagering game. 
     The probability of winning the mega progressive jackpot  111  is referred to as the mega jackpot winning probability P(MegaWin). The progressive jackpot system  100  may be configured to normalize the mega jackpot winning probabilities for the different types of wagering games that are linked to the same mega progressive jackpot  111 . For example, the progressive jackpot system  100  may be configured to provide the players of the progressive jackpot system  100  with substantially the same odds of winning the mega progressive jackpot  111  prize, regardless of the jackpot trigger probability P(JackpotTrigger) of the particular wagering game. Thus, P(MegaWinA), P(MegaWinB), and P(MegaWinC), may be substantially equal even though P(JackpotTriggerA), P(JackpotTriggerB), and P(JackpotTriggerC) may be dissimilar. In other words, after normalization:
 
 P (MegaWin A )≈ P (MegaWin B )≈ P (MegaWin C ).
 
     In some embodiments, the progressive jackpot system  100  may assign each gaming station  102  to have an eligibility probability P 2 (Eligible) for participating in the mega progressive jackpot  111 . This eligibility probability P 2 (Eligible) is a probability for each gaming station  102  to be eligible for winning the mega progressive jackpot  111  during game play. For example, the gaming station  102  may be eligible for winning the mega progressive jackpot  111  during some (but not all) opportunities during game play according to its eligibility probability P 2 (Eligible). As a result, a player may only win the mega progressive jackpot  111  when the jackpot trigger occurs and when the gaming station  102  is eligible. Thus, even if the jackpot trigger is achieved when the gaming station  102  is not eligible, the mega progressive jackpot  111  may not be won. In some embodiments, the same jackpot trigger wins another jackpot (e.g., the major progressive jackpot  108 , the first minor jackpot  110 ) and the mega jackpot  111 , so when a game round is not eligible for mega jackpot play and the player holds a jackpot triggering hand, the player wins another jackpot (e.g., a jackpot with a relatively smaller payout) instead of the mega jackpot  111 . In other embodiments, the jackpot triggers to win the jackpots are different. In some embodiments, there are multiple jackpot triggers, with one premium hand that wins 100% of the jackpot, and other hands that win one of a percentage of the jackpot, an odds payout, or a fixed amount. 
     The probability for each player winning the mega progressive jackpot  111  may be normalized by adjusting an eligibility probability P 2 (Eligible) for each gaming station  102 . For example, the probabilities for winning the mega progressive jackpot  111  may be:
 
 P (MegaWin A )= P (JackpotTrigger A )* P 2(Eligible A );
 
 P (MegaWin B )= P (JackpotTrigger B )* P 2(Eligible B ); and
 
 P (MegaWin C )= P (JackpotTrigger C )* P 2(Eligible C ).
 
     For the mega jackpot winning probabilities P(MegaWin) to be substantially equal among the different gaming stations  102 , the eligibility probabilities P 2 (Eligible) among the different gaming stations  102  may be dissimilar. For example, P 2 (EligibleA), P 2 (EligibleB), and P 2 (EligibleC) may be dissimilar. In other words, different gaming stations  102  may have different probabilities of participation in the mega progressive jackpot  111 . 
     The eligibility probability P 2 (Eligible) of a particular gaming station  102  may be proportional to the inverse of the jackpot trigger probability P(JackpotTrigger) for that particular gaming station  102 . For example, the eligibility probability P 2 (Eligible) may be determined by dividing the mega jackpot winning probability P(MegaWin) by the jackpot trigger probability P 2 (Eligible) of the wagering game. 
     As discussed above, the different wagering games may have different game rules and game outcome probabilities. For example, the following example is provided to illustrate an embodiment of the progressive jackpot system  100  having three different card games linked to the same common major progressive jackpot  108  and/or common mega progressive jackpot  111 . In this example, the first group of gaming stations  102 A 1 ,  102 A 2 , . . .  102 A N  may administer the “THREE CARD POKER®” game, owned and distributed by Bally Gaming, Inc., assignee of the present disclosure as the first wagering game, the second group of gaming stations  102 B 1 ,  102 B 2 , . . .  102 B N  may administer the “LET IT RIDE®” game, owned and distributed by Bally Gaming, Inc., assignee of the present disclosure as the second wagering game, and the third group of gaming stations  102 C 1 ,  102 C 2 , . . .  102 C N  may administer the game “THREE CARD POKER—6 CARD BONUS®” owned and distributed by Bally Gaming, Inc. as the third wagering game. 
     The THREE CARD POKER® game is a poker game in which three cards are dealt to both the player and the dealer. The player hand and the dealer hand are compared to determine whether the player has a winning hand. The top ranking hand is a 3-card Royal Flush (e.g., Ace, King, Queen of the same suit). The probability that a player wins a Royal Flush during THREE CARD POKER® is approximately 1/5,525 (i.e., 0.018%). The 3-card Royal Flush may be used as the jackpot trigger for the THREE CARD POKER® wagering game first or minor jackpot. 
     The LET IT RIDE® game is a five card poker game based on a dealt five card hand. Three cards are dealt to each player, and those cards are combined with two community cards to form a best five-card hand. The top ranking hand is a 5-card Royal Flush (e.g., Ace, King, Queen, Jack and Ten of the same suit). The probability that a player wins a Royal Flush during the LET IT RIDE® game is approximately 1/649,000 (i.e., 0.000154%). The 5-card Royal Flush may be used as the jackpot trigger for the LET IT RIDE® wagering game. 
     The THREE CARD POKER—6 CARD BONUS® game is a three card poker game in which the player may make an optional progressive side bet to play the six card bonus option. For this six card bonus option, the player may be paid when the best five out of the player&#39;s three cards and the dealer&#39;s three cards is a premium 5-card poker hand. The probability that a player receives a five-card Royal Flush (the top ranking hand) from these six cards is approximately 1/108,290 (i.e., 0.000923%). The 5-card Royal Flush may be used as the jackpot trigger for the THREE CARD POKER—6 CARD BONUS® wagering game. 
     Thus, using the jackpot triggers discussed above, the jackpot trigger probabilities P(JackpotTrigger) are summarized in the following table:

     As a result, the jackpot trigger for THREE CARD POKER® may occur more frequently than the jackpot trigger for LET IT RIDE®. The jackpot trigger for LET IT RIDE®, however, may occur less frequently than the jackpot trigger for THREE CARD POKER—6 CARD BONUS®. The progressive jackpot system  100  may be configured to normalize the winning probabilities such that the overall probability for winning the major progressive jackpot  108  is substantially equal for each player regardless of which wagering game they are playing. 
     As discussed above, the progressive jackpot system  100  may assign each gaming station  102  to have an eligibility probability P(Eligible) for participating in the major progressive jackpot  108 . In some embodiments, the eligibility probability P(Eligible) for each gaming station  102  may be determined by dividing the average number of rounds typically required to achieve the top prize in the wagering game, by the sum of the average number of rounds required to achieve a top prize in each linked wagering game type. For example, if “X,” “Y,” and “Z” are the average number of rounds for the jackpot triggers to occur for the respective first, second, and third wagering games, the eligibility probabilities for each round of the wagering games may be:
 
 P (Eligible A )= X /( X+Y+Z );
 
 P (Eligible B )= Y /( X+Y+Z ); and
 
 P (Eligible C )= Z /( X+Y+Z ).
 
     In this example, X=5,525, Y=649,000, and Z=108,290. The eligibility probabilities P(Eligible) are summarized by the following table:

                 THREE CARD POKER ® 
                 P(EligibleA) = 5,525/762,815 = 0.72% 
               
               
                 LET IT RIDE ® 
                 P(EligibleB) = 649,000/762,815 = 85.08% 
               
               
                 THREE CARD POKER - 
                 P(EligibleC) = 108,290/762,815 = 14.20%

     Thus, by adjusting the eligibility probabilities P(Eligible), the major jackpot winning probability P(MajorWin) may be normalized for each wagering game. As a result, the major jackpot winning probability P(MajorWin) may be the same for each player of the progressive jackpot system  100  regardless of which wagering game is being played. The major jackpot winning probabilities P(MajorWin) are shown by the following table:

     Another example is provided to illustrate that the progressive jackpot system  100  may have a major jackpot winning probability P(MajorWin) that is set at any probability that is desirable, but lower than the probability of any individual jackpot trigger. For example, the previous example set the major jackpot winning probability P(MajorWin) to be dependent on the odds of winning the wagering games themselves (i.e., the denominator was the sum of the number of rounds to achieve the jackpot trigger for all underlying wagering games). The probabilities, however, may be normalized for any probability desired. For example, a casino might desire for the major jackpot to accrue to a relatively large value. In order to offer such a large jackpot, a player winning the major progressive jackpot  108  may need to occur infrequently. As a result, the probability of occurrence of a player winning the major progressive jackpot  108  may be selected to be a set number that is relatively low (e.g., 1/5,000,000).

     As a result, players playing the THREE CARD POKER®, LET IT RIDE®, or THREE CARD POKER—6 CARD BONUS® games may have a 1 in 5,000,000 (i.e., 0.00002%) chance of winning the major progressive jackpot  108  regardless of the wagering game they respectively play. A player playing the THREE CARD POKER® game may only have a 0.1105% chance (i.e., 0.00002%*5525) of being eligible to play for the major progressive jackpot  108 . Similarly, players playing the LET IT RIDE® game may have a 12.98% chance (i.e., 0.00002%*649,000) of being eligible to play for the major progressive jackpot  108 . Players playing the THREE CARD POKER—6 CARD BONUS® game may have a 2.17% chance (i.e., 0.00002%*108,290) of being eligible to play for the major progressive jackpot  108 . Although each wagering game has a different probability of being eligible for participation in the major progressive jackpot  108 , each player has the same individual probability of winning the major jackpot (e.g., 1 in 5,000,000) regardless of the underlying wagering game. 
     Another example is provided to illustrate that the progressive jackpot system  100  may link wagering games of a different type to a common major progressive jackpot  108  (whereas the first example provided involved different wagering games of the same type (e.g., card games)). In this next example, the first group of gaming stations  102 A 1 ,  102 A 2 , . . .  102 A N  may administer roulette as the first wagering game, the second group of gaming stations  102 B 1 ,  102 B 2 , . . .  102 B N  may administer blackjack as the second wagering game, and the third group of gaming stations  102 C 1 ,  102 C 2 , . . .  102 C N  may administer a five-card draw poker game as the third wagering game. 
     For a roulette game, the jackpot trigger may be set at the roulette ball landing on 00 (or some other number). The probability of this game outcome may be 1/37 (i.e., 2.7%). For a blackjack game, the jackpot trigger may be set at the player being dealt three unsuited sevens. The probability of this game outcome may be about 1/2,502 (i.e., 0.04%). For a five-card draw poker game, the jackpot trigger may be set at the player being dealt a five card straight flush. The probability of this game outcome may be about 1/72,193 (i.e., 0.0014%). These jackpot trigger probabilities are summarized in the following table:

     The corresponding probability of a current round of the roulette game being eligible for the major progressive jackpot  108  may be the product of 1/1,000,000 and 37/1 (i.e., 0.0037%). The corresponding probability of a current round of the blackjack game being eligible for the major progressive jackpot  108  may be the product of 1/1,000,000 and 2,502/1 (i.e., 0.25%). The corresponding probability of a current round of the poker game being eligible for the major progressive jackpot  108  may be the product of 1/1,000,000 and 72,193/1 (i.e., 7.2%).

     As illustrated by these examples, if the jackpot trigger probability P(JackpotTrigger) is relatively higher, a lower eligibility probability P(Eligible) may be required for the current round to be eligible for participating in the major progressive jackpot  108 . Also, if the jackpot trigger probability P(JackpotTrigger) is relatively low, a higher eligibility probability P(Eligible) may be required for the current round of game play to be eligible for participating in the major progressive jackpot  108 . 
     In some embodiments, a single gaming station  102  may be configured to host a plurality of different wagering games. In such embodiments, a player at the first gaming station  102 A 1  may be allowed to play for the major progressive jackpot  108  while playing the first wagering game (e.g., THREE CARD POKER®), then switch to the second wagering game (e.g., Roulette) on the same first gaming station  102 A 1  while still playing for the same major progressive jackpot  108 . In such embodiments, the eligibility probability P(EligibleA) for the first gaming station  102 A 1  may adjust to the appropriate probability that maintains the same major jackpot winning probability P(MajorWinA) as before with the first wagering game. As a result, the first gaming station  102 A 1  may maintain the same major jackpot winning probability P(MajorWinA) as the other gaming stations  102  linked to the major progressive jackpot  108 . The player may compete for the same major progressive jackpot  108  without the amount of major progressive jackpot  108  being diminished or increased. 
     Although the examples herein may appear to discuss gaming stations  102  being linked together in a single casino, it is also contemplated that gaming stations  102  from different casinos, and gaming stations  102  located in different gaming jurisdictions, may be linked together to participate in the major progressive jackpot  108 . In addition, the different gaming stations  102  may administer the various wagering games in multiple different formats. For example, the gaming stations  102  may administer wagering games offered on different platforms, such as live table game play in a traditional casino environment or “felt games” offered on hybrid table systems that utilize standard cards and electronic betting interfaces (e.g., Bally Gaming, Inc.&#39;s i-TABLE® system), tables that utilize physical chips and virtual cards (e.g., the DIGIDEAL® table system), electronic multiple player gaming systems (e.g., Bally Gaming, Inc.&#39;s TABLE MASTER FUSION® and VEGAS STAR® platforms), on-line gaming, on-line play-for-fun gaming, wagering on wireless devices within a casino, wagering games played on mobile devices (e.g., smart phones, tablet computers, etc.), and on-line games that wager on hands of physical cards being dealt by dealers in remote studios, with live video feed of game play transmitted over the Internet. By linking many gaming stations  102  and/or wagering games offered in multiple formats, increased participation on the major progressive jackpot  108  may occur. As a result, the time needed to complete a jackpot cycle may be reduced while still awarding large jackpots. 
       FIG. 2  is a simplified flowchart  240  illustrating a method of operating a progressive jackpot wagering game. The method may include receiving first wagers from one or more players to participate in a current round of game play at operation  242  and a first minor jackpot. The wagers may be received by the dealer and/or a player interface. For example, on a traditional gaming table, a bet sensor may sense the presence of a wager, and in response to sensing, send a signal to a processor indicating a progressive wager is in action. 
     In some embodiments, the method may also include requiring the player to place a separate major jackpot side wager for participation in the major progressive jackpot  108 . In other embodiments, only one progressive wager is made, with a portion of the bet funding a first minor jackpot and a second portion of the wager funding a major progressive jackpot. This wager is typically raked, and the casino may also use part of the wagers to fund smaller fixed and odds payouts that are part of the bonus game. The one or more jackpot wagers may be mandatory or may be optional. Thus, in some embodiments, the players may elect whether or not to even participate in the major progressive jackpot  108 . If a player elects not to participate in the major progressive jackpot  108 , and only one wager is required to participate in one or both jackpots, in response to a player election not to participate in the major progressive jackpot  108 , a processor may allocate all of the portion of the wager that normally goes to the major progressive jackpot account to the first minor progressive jackpot account. 
     At operation  244 , it is determined if any players placed the major jackpot side wager for a chance at winning the major progressive jackpot  108 . For players that did not place a major jackpot side wager, a regular pay table excluding the major progressive jackpot  108  may be presented at operation  250 . The regular pay table may identify prizes, such as some or all of the minor progressive jackpot  110 , other progressive jackpots, or fixed prizes, or odds payouts (not shown) to be won. By way of non-limiting example, for a Texas Hold &#39;Em poker game, the regular pay table may be: 
                                 Event:   Prize:                  Seven Card Straight Flush   100% of the minor progressive       (minor progressive jackpot trigger)   jackpot 110       Five Aces   100% of the other progressive jackpot       (other progressive jackpot trigger)           Royal Flush   $500       Straight Flush   $100       Four of a Kind    $75       Full House    $4                    
The regular pay table may be presented to the players by the gaming station  102  (e.g., a player interface, community player display, the dealer, a jackpot meters, or combinations thereof). The jackpot triggers for the wagering game may result in winning the minor progressive jackpot  110  or other jackpots, but not the major progressive jackpot  108 .
 
     Returning to operation  244 , for players that did place the major jackpot side wager or a single wager that qualified the player for playing for multiple jackpot prizes including the major progressive jackpot  108 , the eligibility for the major progressive jackpot  108  may be determined. Eligibility may be determined using a randomly generated number that is applied to the eligibility probability P(Eligible) for the particular wagering game. 
     At operation  246 , a random number may be requested by triggering the random number generator (RNG) to produce a random number. In some embodiments, the RNG may be triggered by the dealer selecting a button on the dealer interface of a game controller or an automatic card shuffler for requesting the random number. In some embodiments, the random number may be requested automatically by the gaming station  102  responsive to receipt of the at least one major jackpot side wager. The random number returned may be a randomly selected integer that is within a predetermined range (e.g., a range between 1 and 1,000,000). For the following example, a range of 1,000,000 is described for limiting the random number generation; however, it should be clear that any range may be used so long as the probabilities remain the desired percentage. 
     At operation  248 , the eligibility of the gaming station  102  may be determined according to the eligibility probability P(Eligibility) for the particular wagering game. As an example, if the eligibility probability P(Eligibility) is 2,502/1,000,000, the gaming station  102  may be eligible for the major progressive jackpot  108  if the random number is within a range of 1 to 2,502. The range may be any range of 2,502 numbers (whether consecutive or non-consecutive) within the larger range of 1 to 1,000,000 so long as the eligibility probability P(Eligible) remains the desired percentage. 
     If it is determined that the gaming station  102  is not eligible for the major progressive jackpot  108  during the current round of game play, an indication may be given to the player that the current round is not eligible for the major progressive jackpot  108  at operation  268 . If, however, it is determined that the gaming station  102  is eligible for the major progressive jackpot  108  during the current round of game play, that indication may be given (at operation  252 ) to the player that the current round is eligible for the major progressive jackpot  108  during the current round of game play. The indication of being eligible or not eligible for the major progressive jackpot  108  may be given to the player via a player interface, the dealer, a jackpot meters, chip sensors, or combinations thereof. When the gaming station  102  is a gaming table, all players at the gaming table may be eligible for bonus play when the gaming table is randomly selected. This group play eligibility in such a live table game embodiment may create great excitement and anticipation in the game. In such an embodiment, the eligibility may be displayed on a community display, such as the same display used to display the game rules and/or pay table. In some embodiments, the appropriate indication may be provided to the player after bets have been received, but before actual play of the wagering game. In some instances, the knowledge that the current round of game play is eligible for the major progressive jackpot  108  may add excitement to the current round, which may also encourage participation in the major progressive jackpot side bet in the future. In addition, the player&#39;s strategy for the current round may also change. For example, a player may sacrifice the chances of winning a lower prize in the underlying wagering game in favor of trying to win the major progressive jackpot  108 . Although indicating the eligibility of the current round may affect game play, the current game&#39;s eligibility may be indicated to the players regardless of the effects on game play. In other embodiments, the eligibility of a gaming station  102  for major progressive jackpot play may be determined before wagers are made, encouraging more play when players are eligible for major progressive jackpot play for those players who enjoy long-shot bets, and more play on the first minor progressive jackpot when the gaming station  102  is not eligible for players who enjoy competing to win smaller jackpots. 
     The eligibility of the gaming station  102  may determine which pay table is used for the current round. At operation  250  (not eligible for the major progressive jackpot  108 ), the regular pay table may be presented and used for the current round. At operation  254  (eligible for the major progressive jackpot  108 ), a separate major progressive jackpot pay table may be presented and used for the current round. By way of non-limiting example, for a Texas Hold &#39;Em wagering game, the major progressive jackpot pay table may be: 
                                 Event:   Prize:                  Seven Card Straight Flush   100% of the major progressive       (major progressive jackpot trigger)   jackpot 108       Five Aces   100% of the minor progressive       (minor progressive jackpot trigger)   jackpot 110       Royal Flush   $500       Straight Flush   $100       Four of a Kind    $75       Full House    $4                    
The second pay table may incorporate a top prize from the first pay table, as shown above, or play for the major jackpot may alternatively exclude players from qualifying for first minor jackpot wins. A seven card straight flush may be a major progressive jackpot trigger, which may award 100% of the major progressive jackpot  108 . A hand with five aces may be a minor progressive jackpot trigger, which may award 100% of the minor progressive jackpot  110 . In some embodiments, certain jackpot triggers may award a value less than 100% of one or more of the jackpot amounts.
 
     At operation  258 , the round of game play may be played. In some embodiments the game play may begin at the initiation of the dealer (e.g., by pressing a start button on a dealer interface). In other embodiments, the round of game play may begin automatically without dealer intervention, such as automatically after eligibility for the major progressive jackpot  108  is determined. At operation  260 , the winners are determined based on the game outcomes and the pay table being used for that round. 
     If a winning event is determined, payouts are issued at operation  262 . The winning event may be jackpot trigger, in which case the jackpot is paid to the player. The winning event may simply be a non-jackpot winning event, in which the appropriate amount is paid to the player. If no winning event is determined, no payouts are made. 
     At operation  266 , the jackpot amounts may be adjusted. For example, if the major progressive jackpot  108  was won, the major progressive jackpot  108  may be reset to its starting amount. A typical starting amount is a “seed” amount and this amount is typically funded by the jackpot side bet and held in reserve. When a player wins the full jackpot, emptying the entire jackpot account, this amount held in reserve is transferred to the jackpot account to encourage play. A portion of the bets (from operations  244 ,  242 , or both) may be allocated to the reserve account until the seed amount is reestablished in the reserve account. For pay tables that pay less than the full jackpot amount, the jackpot may be decremented by the amount paid to the player. In this event, no seed money is transferred to the jackpot account. If the major progressive jackpot  108  was not won, the major progressive jackpot  108  may be incremented to increase the amount to be won in a subsequent round. 
     In some embodiments, the jackpot amount may not be incremented until the end of a round of game play, providing the players a fixed amount of money to play for. In other embodiments, the jackpot amount may be incremented before each round of game play, giving the players the opportunity to win back contributions made at operation  242  and operation  244  to the major progressive jackpot  108 . At operation  268 , the round of game play may end. In some embodiments, the dealer may press an end button to end the round. In other embodiments, the round may automatically end. 
     The flowchart  240  of  FIG. 2  described the progressive jackpot system  100  selecting between two pay tables. The present disclosure, however, is not so limited. It is contemplated that any number of pay tables may be used. In some embodiments, the random number received from a RNG may be used to select from a plurality of different pay tables. 
       FIG. 3  is a simplified flowchart  380  illustrating a method of selecting between a plurality of different pay tables. The method may include initiating the RNG at operation  346 . The initiation may be performed manually or automatically. The RNG may generate a random number, which may be used to select a pay table from a plurality of pay tables at operation  348 . The plurality of pay tables may include a regular pay table and a major progressive jackpot pay table, such as those described with respect to  FIG. 2 . The plurality of pay tables may also include a third pay table, a fourth pay table, and a fifth pay table. The third pay table may be:

     Although the plurality of pay tables include jackpot triggers that are directed to a poker wagering game, at other gaming stations  102 , the pay tables may include jackpot triggers directed to other wagering games for the particular gaming stations. 
     Each of the plurality of pay tables may be assigned a range of values, wherein the pay table assigned a range that encompasses the random number produced by the RNG may be selected. For example, the method may include selecting the regular pay table at operation  350 , selecting the major progressive jackpot pay table at operation  354 , selecting the third pay table at operation  370 , selecting the fourth pay table at operation  372 , or selecting the fifth pay table at operation  374  responsive to the RNG producing a random number falling within a range of values assigned to a particular pay table. The ranges assigned to each of the plurality of pay tables may be configured such that the eligibility probability P(Eligible) that the current round qualifies for the major progressive jackpot  108  is inversely proportional to the jackpot trigger probability P(JackpotTrigger), such that the major jackpot winning probability P(MajorWin) is approximately the same across the gaming stations  102  regardless of the wagering game being played. At operation  378  the selected pay table may be presented to the players and used for the current round. 
       FIG. 4  is a simplified block diagram of a progressive jackpot system  400  according to an embodiment of the present disclosure. The progressive jackpot system  400  of  FIG. 4  shows various components that may be used to implement the progressive jackpot system  100  of  FIG. 1 . The progressive jackpot system  400  may include a plurality of gaming stations  102  linked to a major progressive jackpot  108 . The gaming stations  102  may be linked to the major progressive jackpot  108  through one or more servers  406 . The one or more servers  406  may communicate with the gaming stations  102  over one or more networks  404 . As discussed above, a portion of the gaming stations  102  may be linked to a minor progressive jackpot  110 A,  110 B or other progressive jackpots (not shown). 
     The one or more networks  404  (sometimes referred to herein as “networks  404 ”) may be configured to transmit communications between each of the gaming stations  102  and the servers  406 , such as by using an internet protocol (IP). The networks  404  may include a wide area network (WAN), a local area network (LAN), a personal area network (PAN), and combinations thereof. In some embodiments, the servers  406  may be part of a cloud network. The networks  404  may be configured to communicate with the plurality of gaming stations  102  and the servers  406  wirelessly, through a cable, and combinations thereof. Some non-limiting examples of suitable wireless communications may include “Wi-Fi,” BLUETOOTH®, and mobile wireless networks. Some non-limiting examples of suitable cables may include fiber-optic cables, coaxial cables, traditional telephone cables, and Ethernet cables. More detail regarding the networks  404  is discussed with reference to the network  1130  of  FIG. 11 . The networks  404  may also comprise cell phone networks in some embodiments. Non-limiting examples of suitable cell phone network protocols include 3G and 4G networks, for example. 
     The servers  406  may include one or more computing devices (as explained in more detail with respect to  FIG. 5 ) configured to operate the major progressive jackpot  108 . The servers  406  may also be configured to operate the minor progressive jackpots  110  and/or the other progressive jackpots. By way of non-limiting example, the servers  406  may comprise a single dedicated computing device located in a central location, and configured to operate each of the major progressive jackpot  108 , the minor progressive jackpots  110 , and any other progressive jackpots. In other embodiments, the servers  406  may include a computing device configured to operate the major progressive jackpot  108 , and one or more additional computing devices each configured to operate a minor progressive jackpot  110 . In still other embodiments, the servers  406  may include a plurality of computing devices configured to collectively operate the major progressive jackpot  108 , the minor progressive jackpots  110 , and the other progressive jackpots, but that no one server may be dedicated to operate a particular one or more of progressive jackpots. 
     It should also be noted that each of the gaming stations  102  themselves may include a computing device, and may collectively or individually be a part or all of the servers  406 . To illustrate the idea of the gaming stations  102  operating as part of the servers  406 , a dedicated computing device may operate the major progressive jackpot  108  and the minor progressive jackpots  110 , and the gaming stations  102  may each operate another progressive jackpot. The servers  406  may optionally provide online gaming services, and may include a user interaction server  1102 , an asset server  1104 , a game server  1106 , an account server  1110 , and combinations thereof, the specific functions of each of which are discussed in more detail with respect to  FIG. 11 . Some of the servers  406  may optionally be part of an online gaming system ( FIG. 11 ), which, in some embodiments, may be implemented with a computer system  1240 , as discussed with respect to  FIG. 12 . 
     The gaming stations  102 , the server  406  (or both) may include a random number generator (RNG)  428 . The RNG may reside in the server  406 , a gaming station controller, or in other equipment at the game station, such as within a shuffler. The RNG  428  may be configured to generate a random number (e.g., a true random number a pseudo-random number, etc.). The term “random number,” as used herein, may be a true random number or a pseudo-random number. The RNG  428  may be entropy-based, computationally based, and combinations thereof. Random numbers may be used during game play in determining game outcomes according to the game rules, as well as in determining eligibility of the gaming stations  102  for the major progressive jackpot  108 . 
     The progressive jackpot system  100  may also include a plurality of jackpot meters  434  configured to indicate an amount of money to be won in the major progressive jackpot  108 . The jackpot meters  434  may also be configured to indicate an amount of money to be won in a minor progressive jackpot  110  and other minor progressive jackpots, if any. The jackpot meters  434  may be positioned to present the amount to be won in the major progressive jackpot  108  to players and people passing the gaming stations  102  to increase the excitement and appeal of the wagering games hosted at the gaming stations  102 . 
     As discussed above, the gaming stations  102  may be gaming tables that administer different types of card games. The first group of gaming stations  102 A 1 ,  102 A 2 , . . .  102 A N  may be part of a first same-game network, and the second group of gaming stations  102 B 1 ,  102 B 2 , . . .  102 B N  may be part of a second same-game network. In some embodiments, each gaming station  102  of a same-game network may administer the same wagering game. In some embodiments, the gaming stations  102 A 1 ,  102 A 2 , . . .  102 A N  of the first same-game network may include the same electronics as the gaming stations  102 B 1 ,  102 B 2 , . . .  102 B N  of the second same-game network, but that the wagering game hosted thereon may be different. Although many examples herein describe gaming tables and card games, it is contemplated that other types of gaming stations  102  and wagering games may be part of the progressive jackpot system  100  in addition to (or instead of) gaming tables and card games. 
     In operation, each gaming station  102  in the same-game network may have the same eligibility probability P(Eligible) as the other gaming stations  102  in the same-game network. But gaming stations  102  in other same-game networks may have a different eligibility probability P(Eligible) than others, when the game is different. In addition, in some embodiments, only a gaming station  102  that has requested participation (e.g., by requesting a random number) may qualify for participation in the major progressive jackpot  108 . For example, in some embodiments a player may be required to place a major progressive jackpot side wager before eligibility may be determined. If no major progressive jackpot side wager is placed, regular game play may commence without any participation in the major progressive jackpot  108 . In that case, the dealer would not request a determination of eligibility by requesting a random number, and if the system automatically generated a random number in response to a major jackpot side bet being placed, no random number would be requested. In some embodiments, the major progressive jackpot side wager may fund the major progressive jackpot  108 . In some embodiments, the major progressive jackpot side wager may also fund the minor progressive jackpots  110  and other progressive jackpots. Thus, in some embodiments players may place one side wager to participate in both the major and minor progressive jackpots  108 ,  110 . For example, 80% of the side wager after the rake may be applied to the minor progressive jackpot  110 , and 20% of the side wager after the rake may be applied to the major progressive jackpot  108 . Of course, different divisions are contemplated. For example, the side wager after the rake may be split other ways such as 90/10, 30/70, 50/50, 70/30, 80/20, and 90/10. In some embodiments, the input device  530  may include two or more bet sensors per player interface  518 , and separate side wagers may be placed against the major progressive jackpot  108  and the minor progressive jackpot  110 . These funds may be separately raked and the accounts may be separately maintained. 
     The dealer may request a random number selection, or the system may automatically sense a “next round” condition and request a random number automatically when a bet on the occurrence of winning a major jackpot prize is sensed. The random number selected may be used to determine if the gaming station  102  requesting the random number is eligible (i.e., qualifies) for the major progressive jackpot  108 . The player may be notified (e.g., through a player display or a community player display) that the gaming station  102  is or is not eligible for major bonus play after bets have been placed and betting is closed. Providing a visual indication of an opportunity to win the major progressive jackpot  108  after betting closes may add excitement and anticipation to the game play, as well as encourage participation in the major progressive jackpot side wager in the future. 
       FIG. 5  is a simplified block diagram of a gaming station  102  of the progressive jackpot system  100  of  FIG. 4 . The gaming station  102  may include a processor  512  operably coupled to a memory device  514 , a transceiver  516 , one or more player interfaces  518 , and a dealer interface  520 . The transceiver  516  may be configured to enable the gaming station  102  to communicate with the servers  406  ( FIG. 4 ) through the networks  404  ( FIG. 4 ). 
     The player interfaces  518  may be configured to enable one or more players to participate in a wagering game, such as wagering games hosted on the gaming station  102  that include player-processor interaction. The player interfaces  518  may include an input device  530  and an output device  532 . The input device  530  may include a wager receptacle (e.g., a credit card reader, a coin or chip receptacle, an electronic object sensing sensor such as the “coin spot” sensor described in U.S. Pat. No. 7,367,884, the content which is hereby incorporated by reference in its entirety, etc.). The input device  530  may also include other input devices that may depend on the type of wagering game being administered, such as, for example, a touch screen, a camera, a microphone, a slot machine lever, a button array, a keyboard, a mouse, a track pad, and other similar devices. The output device  532  may include a liquid crystal display (LCD), a light-emitting diode (LED) array, a cathode ray tube (CRT), an audio speaker, a plurality of reels, and other output devices appropriate for the wagering game being administered by the gaming station  102 . In some embodiments, the jackpot meters  434  ( FIG. 4 ) may be implemented as part of the one or more player interfaces  518 . 
     In some embodiments, the one or more player interfaces  518  may not be operably coupled to the processor  512 , such as in gaming stations  102  configured to host wagering games not including player-processor interaction. By way of non-limiting example, the one or more player interfaces  518  may be a table with a surface for playing a wagering game (e.g., a card game, a dice game, etc.), a roulette wheel, other wagering game devices, and combinations thereof. In still other embodiments, the gaming station  102  may include one or more player interfaces  518  operably coupled to the processor  512  and the dealer interface  520 . By way of non-limiting example, the gaming station  102  may include a wager receptacle such as a coin slot or a wager indicator such as a “coin spot” sensor operably coupled to the processor  512 , and optionally to the dealer interface  520 . 
     The dealer interface  520  may include a start button  522 , an end button  524 , and a random number generator (RNG) button  526 . A dealer may press the start button  522  to start game play at the gaming station  102 . The dealer may press the end button  524  to end game play at the gaming station  102 . The dealer may press the RNG button  526  to cause the random number generator  428  to be triggered. The dealer interface  520  may also include game-specific devices such as, for example, an automatic card shuffler (not shown), other game-specific devices, and combinations thereof. In some embodiments, the dealer and the dealer interface  520  may be located at the same location as the player and the player interface  518 . In some embodiments, the dealer interface  520  may be located remotely from the rest of the gaming station  102 , and interface with the processor  512  by communicating with the transceiver  516  through the networks  404 . It should also be understood that more than one gaming station  102  may be linked to the same dealer interface  520 . 
     A dealer at the dealer interface  520  may receive wagers from the players desiring to participate in the wagering game. The dealer may also receive an optional side-wager from players desiring to participate in the major progressive jackpot  108  ( FIG. 1 ), minor progressive jackpot  110 , or both. In some embodiments, the dealer may receive the wagers from the players. In other embodiments, the one or more player interfaces  518  may receive the wagers at a wager receptacle. The RNG  428  may be triggered either automatically, or by the dealer pressing the RNG button  526 , responsive to receipt of a side wager to participate in the major progressive jackpot  108 . 
     The processor  512  may be configured to receive the random number from the RNG  428 , and utilize the random number to determine if a current round of game play is eligible for the major progressive jackpot  108  ( FIG. 1 ). The RNG  428  may be initiated to generate the random number responsive to the dealer pressing the RNG button  526  at the dealer interface  520 , or automatically. In some embodiments, the RNG  428  may be integrated as part of the dealer interface  520 . In other embodiments, the gaming station  102  may already include an RNG  428 , such as, for example, in an automatic shuffler, an electronic wagering game, etc. In still other embodiments, the RNG  428  may be integrated at a location remote from the gaming station  102 , such as, for example, at the servers  406 . 
     The memory device  514  may be configured to store machine-readable commands, digital data, and combinations thereof. By way of non-limiting example, the memory device  514  may be a computer readable media, such as read only memory (ROM), a random access memory (RAM), a Flash memory, a hard disk drive, and combinations thereof. The memory device  514  may be operably coupled to the processor  512 . In some embodiments, the memory device  514  may store the game rules and executable commands, which may incorporate the probabilities used therein (including P(JackpotTrigger), P(Eligible)). The memory device  514  may also store one or more pay tables identifying prizes corresponding to one or more possible progressive jackpot triggers that may occur during game play. The pay tables may identify the prizes to be awarded for the major progressive jackpot  108 , the minor progressive jackpots  110 , as well as other progressive jackpots. In addition, the pay tables may indicate fixed prizes, such as, for example, fixed payouts, and other prizes, for one or more other events. 
     The processor  512  may be configured to execute machine-readable commands stored in the memory device  514 . The processor  512  may also be configured to process communications received by the transceiver  516 , and cause the transceiver  516  to send communications over the one or more networks  404  ( FIG. 4 ). By way of non-limiting example, the processor  512  may be a microcontroller, a field programmable gate array (FPGA), a programmable logic controller (PLC), an application-specific integrated circuit (ASIC), and combinations thereof. The processor  512  may be configured to cause the RNG  428 , if any, to generate a random number. 
       FIG. 6  is a simplified block diagram of the server  406  of  FIG. 4 . The server  406  may comprise computing devices including a processor  612  operably coupled to a transceiver  616  and a memory device  614 . The server  406  may further include a RNG  428  configured to generate a random number for determining eligibility of a gaming station  102  for participation in the major progressive jackpot  108  during a current round of play. As discussed above, the random number generation may be performed by the gaming station  102 , by equipment located at the gaming station  102  such as an automatic card shuffler (not shown) and/or the server  406 . 
     The memory device  614  may be configured to store the value attributable to each of the major progressive jackpot  108  and the minor progressive jackpots  110 , if any. The processor  612  may adjust (e.g., increment, decrement) the amounts stored in the memory device  614  of the major progressive jackpot  108 , and the minor progressive jackpots  110  responsive to each wagering game played at each of the gaming stations  102 . The server  406  may also cause the jackpot meters  434  ( FIG. 4 ) to indicate the changed (e.g., increased or decreased) amounts of money in each of the major progressive jackpot  108 , and the minor progressive jackpots  110 . The memory device  314  may also be configured to store the eligibility probability P(Eligible) and/or the jackpot trigger probability P(JackpotTrigger) associated with each of the wagering games administered by each of the gaming stations  102 . 
     In operation, an optional major jackpot side wager (or optional jackpot side wager when only one wager is required to play to win both jackpots) may be received from a player wishing to participate in the major progressive jackpot  108 . If the optional major jackpot side wager is received, the servers  406  may utilize the RNG  428  to determine whether the current round of game play is eligible for the major progressive jackpot  108 . By way of non-limiting example, the servers  406  may cause the current round of game play to be eligible for the major progressive jackpot  108  if the RNG  428  outputs a number that is either greater or smaller than a threshold C within an interval of A to B defining eligibility. The threshold C may be adjustable depending on the probability  436  of the jackpot trigger. Also by way of non-limiting example, the threshold C may be stationary, and the limits A and B of the interval may be adjusted. Consequently, the probability of winning the major progressive jackpot  108  may be the same regardless of the wagering game hosted at a gaming station  102 . In addition, the server  106  may cause an indication to be sent to the player to indicate whether or not the current round of game play is eligible for the major progressive jackpot  108 . The indication may be sent to the player after bets have been made, but before the game play begins. After the game play is complete, the server  106  may adjust the progressive jackpot amounts according to the outcome of the wagering game. 
     It is noted that the gaming stations  102  ( FIG. 5 ) may include similar functional components to the servers  406 . In some embodiments, one or more of the gaming stations  102  may function as both the gaming stations  102  and as the servers  406 . Also, as the gaming stations  102  and the servers  406  may be the same devices in some embodiments, instances of the present disclosure that describe the functions and components of the gaming stations  102  and the servers  406  separately should also be interpreted in the context of the gaming stations  102  acting as the servers  406 . 
     Various platforms are contemplated that are suitable for implementation of embodiments of wagering games according to the present disclosure. For example, embodiments of wagering games may be implemented such that wagers may be received from one or more players, and game play may be administered with the one or more players according to the rules of the wagering games. For example, wagering games may be implemented on gaming tables, which may include physical gaming features, such as physical cards and physical chips, and may include a live dealer and a shuffler or shoe. More specifically, a live dealer may deal physical cards, evaluate hands, accept wagers, accept player elections, issue payouts, and perform other administrative functions of game play. Some embodiments may be implemented on electronic devices enabling electronic gaming features, such as providing electronic displays for display of virtual cards, virtual chips, game instructions, pay tables, etc. Some embodiments may include features that are a combination of physical and electronic features. 
     As an example, embodiments of wagering games may be implemented on a gaming station comprising an individual gaming device, such as an electronic gaming machine (hereinafter EGM), configured to accept wagers and having a display screen and input devices for enabling game play of the wagering games. Such an individual gaming device may be linked with other gaming devices that may be operated, for example, by other players. Some EGM&#39;s may be stationary, such as being located on a casino floor. Other individual electronic gaming devices may be portable devices that may be carried to different locations by the player. Portable devices may include both display of the ongoing game play and input reception for game play by a player. Portable devices may, alternatively or additionally, be configured for receiving input from a player while the game play is displayed on a public monitor or other display device. Game play and game outcomes may also be displayed on a portable device. When the gaming station is an individual gaming device, eligibility of the gaming station permits only one player to be eligible to participate in a game to win a major jackpot prize. 
     As previously noted, any of the present methods and games may be played as a live casino table card game, as a hybrid casino table card game (with virtual cards or virtual chips), on a multi-player electronic platform (as disclosed in U.S. patent application Ser. No. 10/764,827, filed Jan. 26, 2004, published as U.S. Patent Application Publication No. 2005/0164759 on Jul. 28, 2005, now abandoned; U.S. patent application Ser. No. 10/764,994, filed Jan. 26, 2004, now U.S. Pat. No. 7,661,676, issued Feb. 16, 2010; and U.S. patent application Ser. No. 10/764,995, filed Jan. 26, 2004, now U.S. Pat. No. 8,272,958, issued Sep. 25, 2012; the disclosure of each of which applications and patents is incorporated herein in its entirety by this reference), on a personal computer for practice, on a hand-held game for practice, or on a legally-authorized site on the Internet. 
     For example, in one embodiment, the players may be remotely located from a live dealer, and a live dealer and a game table may be displayed to players on their monitors via a video feed. The players&#39; video feeds may be transmitted to the dealer and may also be shared among the players at the table. In a sample embodiment, a central station may include a plurality of betting-type game devices and an electronic camera for each game device. A plurality of player stations, remotely located with respect to the central station, may each include a monitor, for displaying a selected game device at the central station, and input means, for selecting a game device and for placing a bet by a player at the player&#39;s station relating to an action involving an element of chance to occur at the selected game device. Further details on gambling systems and methods for remotely-located players are disclosed in U.S. Pat. No. 6,755,741 B1, issued Jun. 29, 2004, titled “Gambling Game System and Method for Remotely-Located Players,” the disclosure of which is incorporated herein in its entirety by this reference, and in connection with  FIGS. 11 and 12 . 
     In some embodiments, the wagering games described herein may be played against the game administrator, i.e., “the house” (i.e., be “house-banked”), which may involve the game administrator (e.g., a casino or other gaming establishment) receiving (via a dealer who may be employed by the administrator) wagers having real-world monetary value, comparing a player hand against a dealer hand, distributing payouts having real-world monetary value to winning players, and retaining lost wagers. Such “house-banked” embodiments may be implemented in the form of a live table game, in a virtual table game, in an electronic game, or in an on-line game configuration. 
     In other embodiments, the wagering games, or at least one wager associated with the wagering game, may qualify players to play against one another (i.e., be “player-banked”), with payouts on wagers being paid from a pot and losses on wagers being collected into the pot and eventually distributed to one or more players. Such player-banked embodiments may include a player-pooled progressive embodiment, in which a pot is eventually distributed when a predetermined progressive-winning hand combination or composition is dealt. Player-banked embodiments may also include a dividend refund embodiment, in which the pot is eventually distributed in the form of a refund distributed, e.g., pro-rata, to the players who contributed to the pot. 
     Referring to  FIG. 7A , a flow chart diagram of an optional method  700  administering a wagering game, which may be at least partially player-banked, is shown. This method may be most easily implemented in a computer-operated format, such as an online game, but may be implemented as a “felt” table game with equipment necessary to divide the wagers between the various accounts and to track account balances, such as the major and minor jackpot amounts. When implemented as an online game, this method may be used where house-banked games are not permitted, but where player vs. player poker is allowed. The method  700  includes accepting a first mandatory wager, referred to herein as a “poker pot wager,” as indicated at operation  702 . The poker wager is resolved by comparing player hands participating in the game and awarding the poker pot to the player with a winning or best hand at the end of a round of play. The dealer accepts at least a second wager that accumulates in at least a second pot, as indicated at operation  704 . The second wager may comprise, for example, a base game wager (e.g., antes, blinds, play bets, raises, and other bets made on the underlying wagering game) or a side wager. The second wager may be accepted, for example, at the wager receptacle of the input device  530  or by a dealer, as described previously in connection with  FIG. 5 . 
     Optionally, a third pot wager may be accepted and added to at least a third pot. The third pot may be separate from either or both of the poker pot and the game pot. For example, the poker pot, the game pot, and the third pot may include chips located in separate areas on a gaming table, when the wagering game is conducted live in a casino. As another example, the poker pot, the game pot, and the third pot may be displayed as separate amounts on one or more video displays  874 ,  904 ,  916 ,  918 ,  930 ,  1032 ,  1060 ,  1064 , or  1258  (see  FIGS. 8, 9, 10, and 12 ) (e.g., a monitor) controlled by one or more of processors  850 ,  914 ,  928 ,  1097 , or  1242  (see  FIGS. 8, 9, 10 , and  12 ) and may be maintained in separate accounts when the wagering game is conducted online or in another electronic format. The third wager may qualify a player to be eligible to win an additional award, such as, for example, one or more progressive payouts, including a major jackpot (e.g., a progressive jackpot awarded to one or more qualifying players). The third pot may accumulate between rounds of play, and to periodically reduce the balance, a dividend (e.g., a share of the second pot awarded to each participating player) may be awarded to players from the third pot. 
     In some embodiments, the third wager may be a mandatory wager. In other embodiments, the third wager may be optional (e.g., the major progressive jackpot  108  side wager), and the wagering game may be administered with a player without receiving the third wager from the player and without qualifying the player to be eligible to win any award from the third pot. In some embodiments, the third wager may include multiple sub-wagers. For example, the third wager may comprise a wager that causes the player to be eligible in both a first minor progressive jackpot  110  and a major progressive jackpot  108 , or more than one minor progressive jackpot  110  or more than one major progressive jackpot  108 . The third wager may be accepted, for example, at the wager receptacle of the input device  530  or by a dealer, as described previously in connection with  FIG. 5 . 
     In some embodiments, the game pot may be a pooled or linked pot. For example, the game pot may include one or more game wagers accepted from multiple concurrent wagering games. As another example, the game pot may include pooled progressive wagers from those wagering games currently being played and/or may include accumulated game wagers from past wagering games. As specific, nonlimiting examples, the game pot may include all game wagers accepted from a group of tables or local wagering game administration devices at a casino, from multiple groups of remote devices connected to network gaming architecture, or both. In other embodiments, the game pot may not be pooled, and awards for the game wager may be limited to the amounts wagered at a respective table, local wagering game administration device, or group of remote devices. 
     The gaming establishment (e.g., the “house”) may take a “rake,” (e.g., a commission for the house) on at least one wager, such as the poker pot wager, as indicated at operation  706 , the at least one game wager, as indicated at operation  707 , or both. In some embodiments, therefore, a rake may be taken on all wagers, or any wager. For example, the house may collect a portion of the poker pot wager at the time the poker pot wager is placed. Additionally or alternatively, the house may collect a portion of the game wagers at the time the game wagers are placed. 
     The rake may comprise, for example, a fixed percentage of the wagers. More specifically, the percentage of the wagers collected for the rake may be, for example, greater than a theoretical house advantage for the underlying game. As another example, the rake may be less than an average house advantage for play of the wagering game by all players, including average and sub-average players, which may be calculated using a historical house advantage for the wagering game (e.g., a house advantage for the wagering game over the last 5, 10, or 15 years for a given casino or other gaming establishment). As specific, nonlimiting examples, the percentage of the wagers (i.e., either the poker pot wager, the at least one game wager and all jackpot wagers) collected for the rake may be between 3% and 8%, between 4% and 7%, or between 5% and 6%. In other embodiments, the portion of the wagers collected for the rake may comprise a variable percentage of the wagers or may comprise a fixed quantity (e.g., a flat fee) irrespective of the total amount for the wagers, a fixed percentage with a cap, or a time-based fee for increments of time playing the wagering game. Thus, in lieu of, or in addition to, a rake taken on one or more wagers, the house may be compensated in a number of other ways, including, without limitation, a flat fee per round of play, a percentage of wagers made with or without a cap, rental of a player “seat,” or otherwise as is known in the gaming art. All such compensation may be generally referred to as a “commission.” The rake may include money used to fund fixed pay awards, odds payout awards and other awards that are not a percentage (up to 100%) of the amount on the meter, but are part of the bonus payout pay structure. 
     All profits for the house may be made from the rake (or rakes or other commission) in some player-banked embodiments. In such embodiments, wagered amounts in excess of the rake are distributed either in the form of, for example, a progressive payout (as in a “player-pooled progressive” embodiment ( FIG. 7A )), a dividend refund (as in a “dividend refund” embodiment ( FIG. 7B )), or some combination thereof. Thus, the profits for the house are limited. Such limiting of profits for the house and redistribution of wagers back to one or more players may increase the attractiveness of the wagering game to both inexperienced and highly skilled players. Because the amount earned by the house is known, highly skilled players may perceive that their skill will enable them to increase winnings, and inexperienced players may be enticed by the possibility of winning or otherwise earning a portion or all of one or more of the pots. In other embodiments, the house may make profits on the rake and on losses from one or more of the wagers including losses resulting from optimal and suboptimal play. 
     The rake may be maintained in a rake account, and profits for the house may be deducted from the rake account. When and if taken from the poker pot wagers, the poker wager pot rake (operation  706 ) may be taken by, for example, electronically transferring funds from the poker pot wagers to a poker pot rake account (e.g., as instructed by a game server  1106  (see  FIG. 11 ) using casino account servers  1110  (see  FIG. 11 )) or physically removing or exchanging money or representations of money from the poker pot wagers or the poker pot itself on a live table. Likewise, when and if taken from the game wagers, the game wager rake (operation  707 ) may be taken by, e.g., electronically transferring funds from the game pot wagers to a game pot rake account (e.g., as instructed by the game server  1106  (see  FIG. 11 ) using casino account servers  1110  (see  FIG. 11 )) or physically removing or exchanging money or representations of money from the game wagers or the game pot itself on a live table. 
     In some embodiments, the poker pot wager may be accepted (operation  702 ) at the beginning of a round of administration of the wagering game. One or more of the game wagers may be accepted (operation  704 ) at the beginning of the round as well depending on the underlying wagering game. In some embodiments, additional game wagers may be accepted (operation  704 ), possibly raked (operation  707 ), and added to the game pot (operation  705 ) in the intermediate segments of the round of play depending on the underlying wagering game. 
     The underlying wagering game may be played as described above, including resolving the game wagers received during the round of play, as indicated at operation  708 . For example, the underlying wagering game may be played according to the rules of the underlying wagering game. 
     At the end of a round of play, the first wager may be resolved and the first “poker” pot may be awarded to at least one player, as indicated at operation  710 . Each successive round of making wagers, playing the round, and resolving wagers may constitute a round of play, and the first pot may be awarded to at least one player at the end of each round of play. The player to whom the first pot is awarded may hold a winning hand or at least a tying hand for that round of play according to the rules of the underlying wagering game amongst other players at the table. 
     In some wagering games involving playing cards, a predetermined winning hand combination may comprise, for example, a four-of-a-kind, a Full House, a flush, a straight, a three-of-a-kind, two pair, or one pair. The hands qualifying as new winning hand combinations may be predetermined at the beginning of each round of play in some embodiments. In other embodiments, new winning hand combinations may be predetermined at the beginning of play and may remain fixed until it is determined that at least one player hand achieves a predetermined winning hand combination, at which time new winning hand combinations may be predetermined. In still other embodiments, the hand combinations qualifying as winning hand combinations may be predetermined at the outset of the wagering game and remain fixed for the duration of the wagering game. The hands qualifying as winning hand combinations may be predetermined at random from a list of possible winning hand combinations, from among a schedule with a fixed rotation of possible winning hand combinations, or using a fixed table of winning hand combinations. 
     In some wagering games involving playing cards, a premium winning hand composition may comprise, for example, a four-of-a-kind, a straight flush, or a Royal Flush. The hand compositions qualifying as premium winning hand compositions may remain fixed throughout the duration of the wagering game or may change during the wagering game. For example, after it has been determined that a player hand has achieved a premium winning hand composition, the hand compositions qualifying as premium winning hand compositions may be made more restrictive or less restrictive. As a specific, nonlimiting example, after identification of a player hand achieving a straight flush, the hand compositions qualifying as premium winning hand compositions may be restricted to Royal Flushes or may be expanded to include four-of-a-kinds. The hands qualifying as premium winning hand compositions may be predetermined at random from a list of possible premium winning hand compositions, following a schedule with a fixed rotation of possible premium winning hand compositions, or according to a fixed table of premium winning hand compositions. 
     In embodiments in which the game pot is a progressive pot, the amount awarded from the game pot for achieving a premium winning hand composition may be a progressive payout at least as great as a maximum progressive payout for achieving a predetermined winning hand composition. For example, the entire game pot may be awarded when a player or multiple players are dealt a premium winning hand composition, and only a portion of the game pot may be awarded when a player or multiple players are dealt a predetermined winning hand combination. 
     Awarding the game pot or a portion of the game pot may comprise crediting a player account with funds from the game pot or may comprise distributing physical money or physical representations of money from the game pot to the player. 
     Before, between, or after resolving the game wagers (operation  708 ), determining whether a progressive-winning condition occurred (operation  710 ), awarding a progressive payout (operation  712 ), or any combination thereof, the poker pot wager may be resolved, and the poker pot may be awarded to at least one player, as indicated at operation  716 . Each successive round of receiving wagers, dealing cards, and resolving wagers may constitute a round of play, and the poker pot may be awarded to at least one player before the end of each round of play. The player to whom the poker pot is awarded may hold a highest ranking hand amongst other players at the table according to the rules of the underlying wagering game. 
     Awarding the poker pot or the portion of the poker pot may comprise crediting a player account of each winning player or may comprise distributing physical money or physical representations of money to each winning player. 
     In some embodiments, an entire amount of the poker pot may be awarded to at least one player before the end of each round of play. In such embodiments, the poker pot may be a non-progressive pot. Awarding the entire poker pot to at least one player at the end of each round of play may enable an online implementation of the wagering game to qualify as a legal form of online poker play under relevant statutes. For example, in games that require a mandatory pot bet that has no house advantage, and all other game wagers are raked and then allocated to a second pot, the game may qualify as “poker” to gaming authorities, especially for online versions of the games. Awarding the entire amount of a poker pot to at least one player at the end of each round of play redistributes lost poker wagers attributable to suboptimal play to other players, rather than to the house. Accordingly, such a wagering game may be particularly attractive to players who perceive themselves as being highly skilled in the wagering game and, therefore, more able to take advantage of suboptimal play by other players. 
     In some embodiments, a portion of the poker pot may be awarded to at least one player at the end of each round of play (operation  716 ). For example, the house may take a rake on the poker wager (operation  706 ), which may still enable the wagering game to qualify as a legal form of online gambling under relevant statutes. The rake taken may comprise, for example, between 1% and 8%, between 2% and 6%, or between 3% and 5% of the first wager. The rake amounts on each wager may be more than, less than, or equal to the rake taken on other wagers in some embodiments. 
     In still other embodiments, a portion of the poker pot may remain (e.g., at operation  703  and/or operation  714 ) in the poker pot or may be redistributed to another pot (e.g., the game pot) to be awarded in a subsequent round of play as a progressive payout or as a dividend refund (see  FIG. 7B ). In such an example, the portion of the poker pot wager remaining in the poker pot or redistributed to another pot may comprise, for example, a fixed percentage of the poker pot wager, a variable percentage of the poker pot wager (e.g., an odds payout may be awarded and the remainder retained in the poker pot or redistributed to the other pot), or a fixed amount. 
     In embodiments where the second pot is a progressive pot, at least a portion of the second pot may be awarded to at least one player when a predetermined jackpot trigger occurs, such as, for example, a predetermined winning hand combination is dealt, as indicated at operation  712 , or when a premium winning hand composition is dealt, as also indicated at operation  712 . For example, a game may pay a progressive payout for a seven card straight flush in a Texas Hold &#39;Em wagering game. The second pot may not be awarded at the end of each round of play, but may grow during each successive round in which the predetermined jackpot trigger does not occur. Awarding the second pot or a portion of the second pot may comprise crediting a player account with funds from the second pot or may comprise distributing physical money or physical representations of money from the pot to the player. 
     In some embodiments involving a no-house-advantage poker pot awarded at the end of each round and a progressive game pot that receives all other game wagers, all players participating in the wagering game from whom the at least one game wager has been received may be eligible to win the game pot or a portion of the game pot. Players who are ineligible to win the poker pot, and players from whom fold indications have been received but from whom one or more other active wagers in play have been received, may be eligible to win the game pot or a portion of the game pot. 
     In some embodiments, the game pot may be seeded with money from the game pot rake account or a reserve account (as indicated at operation  718 ) at the beginning of play, after the game pot or a portion of the game pot has been awarded, or both. In some embodiments, a minimum account balance sufficient to cover expected losses is retained when distributing a progressive payout (operation  712 ) such that no seed money is required in the game pot. For example, the game pot may be seeded from the rake account of the house (operation  718 ), and the house may maintain an amount of funds in the rake account sufficient to significantly reduce (e.g., to essentially eliminate) the likelihood that any payouts made from the rake account and any seeding amounts withdrawn from the rake account exhaust or overdraw the rake account. In some embodiments, a casino reserve account may be provided to fill the rake account in the event of an overdraw. Such seeding may incentivize players to participate in the wagering game, and specifically to place a game wager (e.g., a progressive wager) to be eligible for the progressive payout from the game pot. In addition, such seeding may reduce the likelihood that the amount of funds in the game pot may be insufficient to cover all the payouts to players. For example, where a player hand achieves a premium winning hand composition in one round of play, a player hand achieves a predetermined winning hand combination in the immediately following round of play, and a fixed odds payout is to be awarded to the player holding the predetermined winning hand combination, the amount seeded to the game pot between those rounds of play may be at least as great as the maximum fixed odds payout awardable for any predetermined winning hand combination. The game pot may be seeded each time the game pot is awarded in its entirety or each time the amount in the game pot is lower than the maximum fixed odds payout. 
     As a specific, nonlimiting example, a player-banked wagering game with a player-pooled progressive configuration may comprise accepting a first player-pooled wager from each player and adding the first player-pooled ante wagers to a player-pooled pot which may be reflected by the presence of the chips or images of the chips grouped together with one another on the playing surface. The player-pooled pot may be a no-house-advantage pot that is awarded according to the game rules of the underlying wagering game. Any additional wagers (e.g., ante, bonus side wagers, other game play wagers, etc.) and added to another pot from which payouts from the game may be distributed. In addition, an optional jackpot wager that qualifies the player for eligibility to participate in at least a major progressive jackpot and in some embodiments also qualifies the player to participate in a minor jackpot event may be accepted. A random number generator  428  ( FIGS. 4, 5, and 6 ) may be initiated to produce a random number. The random number may be utilized to determine whether a current round of game play is eligible for a major progressive jackpot  108  ( FIG. 1 ). A determined probability that the current round of game play is eligible for the major progressive jackpot  108  may be inversely proportional to a probability of the jackpot trigger. In addition, the at least one player may be informed of whether or not the current round of game play is eligible for the major progressive jackpot  108  before initiation of the current round of game play. The underlying wagering game may be resolved according to the game rules. The major progressive jackpot  108  may be resolved and distributed responsive to the occurrence of the jackpot trigger when the gaming station  102  is determined to be eligible according to the eligibility probability. 
     Referring to  FIG. 7B , shown is a flowchart diagram of a method  720  of administering a wagering game, which may be at least partially player-banked, according to a dividend refund embodiment. The method  720  is largely the same as the method  700  of the player-pooled progressive ( FIG. 7A ), with the exception that, rather than determining whether a progressive-winning condition has occurred (operation  710  ( FIG. 7A )), the method  720  includes determining whether a trigger event condition has occurred, as indicated at operation  722 , and, if so, distributing the game pot to one or more past or present players of the wagering game, as indicated at operation  724  (rather than distributing the game pot as a progressive payout as at operation  712  ( FIG. 7A )). In such embodiment, the game pot may accumulate between rounds of play, and, to periodically reduce the balance, a dividend (e.g., a share of the game pot awarded to each participating player) may be awarded to players from the game pot. Thus, what would otherwise be the profits from lost wagers, less amounts raked by the house, are redistributed back to the players, rather than collected by the house as revenue. Thus, the distribution is not a payout on the underlying game, but a refund. 
     In embodiments where payouts from the game pot comprise dividend distributions, the game pot may be distributed among a plurality of players upon the occurrence of a predetermined event (referred to herein as a “trigger event”), as indicated at operation  722 . The predetermined, trigger event may not be based, for example, on player skill or chance events occurring in the underlying wagering game. The predetermined trigger event may comprise, for example, determination that at least one player participated for a predetermined number of hands; completed a predetermined number of rounds of play at a given table, electronic gaming machine, or remote gaming device; reached a predetermined time limit since play commenced; or reached a predetermined amount within the game pot. The predetermined trigger event or condition may be time-based, pot-based (or pool-based), game-based, or other-based. Further details on pot distributions based on predetermined trigger events and conditions are disclosed in the U.S. patent application Ser. No. 13/871,824, filed Apr. 26, 2013, published as U.S. Patent Application Publication No. 2013/0296025 on Nov. 7, 2013, and titled “Distributing Supplemental Pot in Wagering Games Based on Predetermined Event,” the disclosure of which is incorporated herein in its entirety by this reference. 
     The dividend distributions may be divided at least among players currently participating in the wagering game. In some embodiments, the dividend distributions may also be paid to players who previously contributed to the game pot but who have since ceased participating in the wagering game. In some embodiments, the dividend distributions may not be paid to players from whom contributions to the game pot have not been received since the last dividend distribution was paid. The percentage of the game pot refunded to each player as a dividend distribution may be, for example, approximately equal to the percentage of hands won by each player, the percentage of first pot winnings won by each player based on game play, the percentage of total wager amounts received from each player, the proportional number of wagers received from each player, the proportional length of time spent playing the wagering game by each player, or an equal percentage for each player eligible to receive a dividend distribution from the game pot. 
     The dividend refund may be distributed in the form of a credit made to the receiving players&#39; accounts. In some embodiments, the refund may be paid without concurrently alerting the player, though the refund may be noticeable when and if the player next checks his or her balance in her player account. 
     As a specific, non-limiting example, a player-pooled wagering game with a dividend refund configuration may include utilizing an account server to link a plurality of gaming stations to a major progressive jackpot. A player-pooled wager may be received from each player and the first player-pooled wagers to a player-pooled pot. Additional wages (e.g., ante, side wagers, etc.) may be received from each player and the other wagers may be added to another pot separate from the player-banked pot. A rake may be collected from the other pot and/or the player-pooled pot. An optional major progressive jackpot side wager may also be received for participation in the major progressive jackpot from one or more of the plurality of players at one or more of the plurality of gaming stations. A random number generator may be initiated to produce a random number. The player-pooled wagers may be resolved according a highest hand of the players of the wagering game. The other wager may be resolved according to game rules of the game play with payouts being distributed from the other pot. In addition, at least a portion of the other pot may be distributed among the players when a predetermined event has occurred. The optional progressive jackpot side wager may be resolved by utilizing the random number to determine whether a current round of game play is eligible for the major progressive jackpot and an occurrence of a jackpot trigger, wherein a determined jackpot winning probability has been normalized for each gaming station of the plurality of gaming stations by utilizing dissimilar eligibility probabilities for each gaming station participating in the major progressive jackpot. 
     In some embodiments, wagering games may be administered without players risking money in connection with the wagers (i.e., “play-for-fun” games). Access to play-for-fun wagering games may be granted on a time period basis in some embodiments. For example, upon initially joining the wagering game, each player may automatically be given wagering elements, such as, for example, chips, points, or simulated currency, that is of no redeemable value. After joining, the player may be permitted to place bets using the wagering elements and a timer may track how long the player has been participating in the wagering game. If the player exhausts his or her supply of the wagering elements before a predetermined period of time has expired, the player may be permitted to simply wait until the period of time passes to rejoin the game, at which time another quantity of the wagering elements may be distributed to the player to permit the player to resume participation in the wagering game. 
     In some embodiments, a hierarchy of players may determine the quantity of wagering elements given to a player for each predetermined period of time. For example, players who have been participating in the wagering game for a longer time, who have played closest to optimal strategy for the game, who have won the largest percentage of wagers, who have wagered the most in a play-for-pay environment, or who have won the largest quantities of wagering elements from their wagers may be given more wagering elements for each allotment of time than players who have newly joined, who have played according to poor strategy, who have lost more frequently, or who have lost larger quantities of wagering elements. In some embodiments, the hierarchy of players may determine the duration of each allotment of time. For example, players who have been participating in the wagering game for a longer time, who have played closest to optimal strategy for the game, who have won the largest percentage of wagers, or who have won the largest quantities of wagering elements from their wagers may be given shorter allotments of times to wait for an award of more wagering elements than players who have newly joined, who have played according to poor strategy, who have lost more frequently, or who have lost larger quantities of wagering elements. In some embodiments, players who have not run out of wagering elements after the period of time has expired may have the balance of their wagering elements reset for a subsequent allotment of time. In other embodiments, players who have not run out of wagering elements may be allowed to retain their remaining wagering elements for subsequent allotments of time, and may be given additional wagering elements corresponding to the new allotment of time to further increase the balance of wagering elements at their disposal. Players may be assigned to different categories of players, which determine the number of wagering elements awarded. In a given period of time, higher level players, or players who have invested more time playing the game may be allotted more wagering elements per unit of time than a player assigned to a lower level group. 
     Therefore, in some embodiments, the wagering game may be administered by receiving wagers (e.g., actual wagers may depend on the underlying wagering game) of no real-world monetary value, and payouts (e.g., actual payouts may depend on the underlying wagering game) may be paid without transferring real-world monetary value to the players. Such embodiments, referred to herein as “free play-for-fun” embodiments are nonetheless contemplated as modes of carrying out the methods described herein. 
     In some embodiments, referred to herein as “social play-for-fun” embodiments, a player may be permitted to redeem an access token of no redeemable face value, such as, for example, points associated with a player account (e.g., social media account credits, online points associated with a transacting account, etc.), to compress the period of time and receive more wagering elements. The access tokens may be sold or may be given without directly exchanging money for the access tokens. For example, access tokens may be allocated to players who participate in member events (e.g., complete surveys, receive training on how to play the wagering game, share information about the wagering game with others), spend time participating in the wagering game or in a player account forum (e.g., logged in to a social media account), or view advertising. Thus, an entity administering social play-for-fun wagering games may not receive money from losing player wagers or may not take a rake on wagers, but may receive compensation through advertising revenue or through the purchase of access tokens redeemable for time compressions to continue play of the wagering game or simply to increase the quantity of wagering elements available to a player. 
     After receipt of an indication that a player has stopped participating in a play-for-fun wagering game (e.g., a free play-for-fun embodiment, a social play-for-fun embodiment), any remaining quantities of the wagering elements may be relinquished by the player and retained by the administrator, in some embodiments. For example, receipt of an indication that the player has logged out of a play-for-fun wagering game administered over the Internet may cause any remaining wagering elements associated with a respective player to be lost. Thus, when the player rejoins the play-for-fun wagering game, the quantity of wagering elements given to the player for an allotment of time may not bear any relationship to the quantity of wagering elements held by the player when he or she quit playing a previous session of the wagering game. In other embodiments, upon receipt of an indication that a player has stopped playing, the quantity of wagering elements held by the player at that time may be retained and made available to the player, along with any additional quantities of wagering elements granted for new allotments of time, upon receipt of an indication that the player has rejoined the wagering game. 
     As a specific, nonlimiting example, a play-for fun wagering game may comprise allocating from a server  106  a quantity of valueless wagering elements to at least one player at a gaming station  102  ( FIG. 1 ). The server  406  may receive authorization from the at least one player to allocate at least a portion of the valueless wagering elements to an optional side-wager. A RNG  428  ( FIGS. 4, 5, and 6 ) may be initiated to produce a random number. The random number may be used to determine whether a current round of game play is eligible for a major progressive jackpot  108 . The major progressive jackpot  108  may comprise valueless wagering elements. A determined probability that the current round of game play is eligible for the major progressive jackpot  108  may be inversely proportional to a probability of the jackpot trigger. The at least one player may be informed of whether or not the current round of game play is eligible for the major progressive jackpot before initiation of the current round of game play. The valueless wagering elements of the major progressive jackpot  108  may be transmitted to the at least one player responsive to occurrence of the jackpot trigger. 
     Referring to  FIG. 8 , illustrated is an example of an individual electronic gaming device  800  (e.g., an electronic gaming machine (EGM)) configured for implementation of embodiments of wagering games according to the present disclosure. The gaming station may comprise an individual electronic gaming device  800  that may include an individual player position  814  that includes a player input area  832  configured to enable a player to interact with the individual electronic gaming device  800  through various input devices (not shown). The individual electronic gaming device  800  may include a gaming screen  874  configured to display indicia for interacting with the individual electronic gaming device  800 , such as through processing one or more programs stored in memory  840  to implement the rules of game play at the individual electronic gaming device  800 . Accordingly, game play may be accommodated without involving physical playing cards, poker chips, and/or live personnel. The action may instead be simulated by a control processor  850  operably coupled to the memory  840  and interacting with and controlling the individual electronic gaming device  800 . 
     Although the figure has an outline of a traditional gaming cabinet, the individual electronic gaming device  800  may be implemented in any number of ways, including, but not limited to, client software downloaded to a portable device, such as a smart phone, tablet, or laptop personal computer. The individual electronic gaming device  800  may also be a non-portable personal computer (e.g., a desktop or all-in-one computer) or other computing device. In some embodiments, client software is not downloaded but is native to the device or is otherwise delivered with the device when distributed to a player. 
     A communication device  860  may be included and operably coupled to the processor such that information related to operation of the individual electronic gaming device  800 , information related to the game play, or combinations thereof may be communicated between the individual electronic gaming device  800  and other devices (not shown) through a suitable communication media, such, as, for example, wired networks, Wi-Fi networks, and cellular communication networks. 
     The gaming screen  874  may be carried by a generally vertically extending cabinet  876  of the individual electronic gaming device  800 . The individual electronic gaming device  800  may further include banners (not shown) configured to communicate rules of game play and/or the like, such as along a top portion  878  of the cabinet  876  of the individual electronic gaming device  800 . The individual electronic gaming device  800  may further include additional decorative lights (not shown), and speakers (not shown) for transmitting and/or receiving sounds during game play. Further detail of an example of an individual electronic gaming device  800  (as well as other embodiments of tables and devices) is disclosed in U.S. patent application Ser. No. 13/215,156, filed Aug. 22, 2011, published as U.S. Patent Publication No. 2013/0053117 on Feb. 28, 2013, and titled “Methods of Managing Play of Wagering Games and Systems for Managing Play of Wagering Games,” the disclosure of which is incorporated herein in its entirety by this reference. 
     Some embodiments may be implemented at locations that include a plurality of player stations. Such player stations may include an electronic display screen for display of game information, such as displaying virtual cards, virtual chips, and game instructions, and for accepting wagers and facilitating credit balance adjustments. Such player stations may, optionally, be integrated in a table format, may be distributed throughout a casino or other gaming site, or may include both grouped and distributed player stations. While some features may be automated through electronic interfaces (e.g., virtual cards, virtual chips, etc.), some features may remain in the physical domain. As such, the game play may be administered by a live dealer, a virtual dealer, or a combination of both. 
     Referring to  FIG. 9 , systems and methods of the present disclosure may be implemented on a gaming table with electronic player interfaces. An example of a suitable table  900  configured for implementation of embodiments of wagering games according to the present disclosure is shown. The table  900  may include a playing surface  904 . The table  900  may include a plurality of player stations  912   a  through  912   g . Each player station  912   a  through  912   g  may include a player interface  916   a  through  916   g , which may be used for displaying game information (e.g., game instructions, input options, wager information including virtual chips, game outcomes, etc.). The player interface  916   a  through  916   g  may include a display screen in the form of a touch screen, which may be at least substantially flush with the playing surface  904  in some embodiments. Each player interface  916   a  through  916   g  may be coupled respectively with its own local game processor  914   a  through  914   g  (shown in dashed lines), although, in some embodiments, a central game processor  928  (shown in dashed lines) may be employed and may communicate directly to player interfaces  916   a  through  916   g . In some embodiments, a combination of individual local game processors  914   a  through  914   g  and the central game processor  928  may be employed. 
     A communication device  960  may be included and may be operably coupled to one or more of the local game processors  914 , the central game processor  928 , or combinations thereof, such that information related to operation of the table  900 , information related to the game play, or combinations thereof may be communicated between the table  900  and other devices (not shown) through a suitable communication media, such as, for example, wired networks, Wi-Fi networks, and cellular communication networks. 
     The table  900  may further include additional features, such as a dealer chip tray  920 , which may be used by the dealer to cash players in and out of the wagering game, whereas wagers and balance adjustments during game play may be performed using virtual chips. For embodiments using physical cards  906   a ,  906   b , the table  900  may further include a card-handling device  922  that may be configured to shuffle, read, and deliver physical cards for the dealer and players to use during game play or, alternatively, a card shoe configured to read and deliver cards that have already been randomized. For embodiments using virtual cards, such virtual cards may be displayed at the individual player interfaces  916   a  through  916   g . Common virtual cards may be displayed in a common card area (not shown). 
     The table  900  may further include a dealer interface  918 , which, like the player interfaces  916   a  through  916   g , may include touch screen controls for assisting the dealer in administering the wagering game. The table  900  may further include an upright display  930  configured to display images that depict game information such as pay tables, hand counts, historical win/loss information by player, and a wide variety of other information considered useful to the players. The upright display  930  may be double sided to provide such information to players as well as to the casino pit. 
     Further detail of an example of a table and player displays is disclosed in U.S. Patent Application Publication No. 2010/0016050, filed Jul. 15, 2008, published Jan. 21, 2010, now U.S. Pat. No. 8,262,475, issued Sep. 11, 2012, and now titled “Chipless Table Split Screen Feature,” the disclosure of each of which application and patent is incorporated herein in its entirety by this reference. Although an embodiment is described showing individual discrete player stations, in some embodiments, the entire playing surface  904  may be an electronic display that is logically partitioned to permit game play from a plurality of players for receiving inputs from, and displaying game information to, the players, the dealer, or both. 
     Referring to  FIG. 10 , methods and systems of the present disclosure may be implemented on a multiple player electronic game platform. As shown in the Figure, another example of a suitable table  1000  configured for implementation of embodiments of wagering games having a virtual dealer according to the present disclosure is shown. Other embodiments may not include a virtual dealer but instead display dealer hand information but not a representation of a dealer. The table  1000  may include player positions  1014   a  through  1014   e  that are arranged in a bank about an arcuate edge  1020  of a video device  1058  that may comprise a card screen  1064  and a dealer screen  1060 . The dealer screen  1060  may display a video simulation of the dealer (i.e., a virtual dealer) for interacting with the video device  1058 , such as through processing one or more stored programs stored in memory  1095  to implement the rules of game play at the video device  1058 . The dealer screen  1060  may be carried by a generally vertically extending cabinet  1062  of the video device  1058 . The card screen  1064  may be configured to display at least one or more of the dealer&#39;s cards, community cards, and/or player&#39;s cards by the virtual dealer on the dealer screen  1060  (virtual dealer not shown in  FIG. 10 ). 
     Each of the player positions  1014   a  through  1014   e  may include a player interface area  1032   a  through  1032   e  that is configured for wagering and game play interactions with the video device  1058  and/or virtual dealer. Accordingly, game play may be accommodated without involving physical playing cards, poker chips, and/or live personnel. The action may instead be simulated by a control processor  1097  interacting with and controlling the video device  1058 . The control processor  1097  may be located internally within, or otherwise proximate to, the video device  1058 . The control processor  1097  may be programmed, by known techniques, to implement the rules of game play at the video device  1058 . As such, the control processor  1097  may interact and communicate with display/input interfaces and data entry inputs for each player interface area  1032   a  through  1032   e  of the video device  1058 . Other embodiments of tables and gaming devices may include a control processor that may be similarly adapted to the specific configuration of its associated device. 
     A communication device  1099  may be included and operably coupled to the control processor  1097  such that information related to operation of the table  1000 , information related to the game play, or combinations thereof may be communicated between the table  1000  and other devices (not shown) through a suitable communication media, such, as, for example, wired networks, Wi-Fi networks, and cellular communication networks. 
     The video device  1058  may further include banners (not shown) configured to communicate rules of play and/or the like, which may be located along one or more walls  1070  of the cabinet  1062 . The video device  1058  may further include additional decorative lights (not shown) and speakers (not shown), which may be located on an underside surface  1066 , for example, of a generally horizontally depending top  1068  of the cabinet  1062  of the video device  1058  generally extending toward the player positions  1014   a  through  1014   e.    
     Further detail of an example of a table and player displays is disclosed in U.S. patent application Ser. No. 10/764,995, filed Jan. 26, 2004, published as U.S. Patent Application Publication No. 2005/0164762 on Jul. 28, 2005, now U.S. Pat. No. 8,272,958, issued Sep. 25, 2012, and titled “Automated Multiplayer Game Table with Unique Image Feed of Dealer,” the disclosure of each of which application and patent is incorporated herein in its entirety by this reference. Although an embodiment is described showing individual discrete player stations, in some embodiments, the entire playing surface (e.g., player interface areas  1032   a  through  1032   e , card screen  1064 , etc.) may be an electronic display that is logically partitioned to permit game play from a plurality of players for receiving inputs from, and displaying game information to, the players, the dealer, or both. 
     Wagering games in accordance with embodiments of the disclosure may be administered over the Internet, or otherwise online, in one embodiment using a gaming system employing a client server architecture. Referring to  FIG. 11 , illustrated is a schematic block diagram of a gaming system  1100  for implementing wagering games according to an embodiment of the present disclosure. The gaming system  1100  enables end users operating user device  1120  to access proprietary and/or non-proprietary game content. Such game content may include, without limitation, various types of wagering games such as card games, dice games, big wheel games, roulette, scratch off games (“scratchers”), and any other wagering game where the game outcome is determined, in whole or in part, by one or more random events. This includes, but is not be limited to, Class II and Class III games as defined under 25 U.S.C. § 2701 et seq. (“Indian Gaming Regulatory Act”). Such games may include banked and/or non-banked games. 
     The wagering games supported by the gaming system  1100  may be operated with real currency or with virtual credits or other virtual (e.g., electronic) value indicia. For example, the real currency option may be used with traditional casino and lottery-type wagering games in which money or other items of value are wagered and may be cashed out at the end of a game session. The virtual credits option may be used with wagering games in which credits (or other symbols) may be issued to a player to be used for the wagers. A player may be credited with credits in any way allowed, including, but not limited to, a player purchasing credits; being awarded credits as part of a contest or a win event in this or another game (including non-wagering games); being awarded credits as a reward for use of a product, casino, or other enterprise, time played in one session, or games played; or may be as simple as being awarded virtual credits upon logging in at a particular time or with a particular frequency, etc. Although credits may be won or lost, the ability of the player to cash out credits may be controlled or prevented. In one example, credits acquired (e.g., purchased or awarded) for use in a play-for-fun game may be limited to non-monetary redemption items, awards, or credits usable in the future or for another game or gaming session. The same credit redemption restrictions may be applied to some or all of credits won in a wagering game as well. 
     An additional variation includes web-based sites having both play-for-fun and wagering games, including issuance of free (non-monetary) credits usable to play the play-for-fun games. This may attract players to the site and to the games before they engage in wagering. In some embodiments, a limited number of free or promotional credits may be issued to entice players to play the games. Another method of issuing credits includes issuing free credits in exchange for identifying friends who may want to play. In another embodiment, additional credits may be issued after a period of time has elapsed to encourage the player to resume playing the game. The gaming system  1100  may enable players to buy additional game credits to allow the player to resume play. Objects of value may be awarded to play-for-fun players, which may or may not be in a direct exchange for credits. For example, a prize may be awarded or won for a highest scoring play-for-fun player during a defined time interval. All variations of credit redemption are contemplated, as desired by game designers and game hosts (the person or entity controlling the hosting systems). 
     The gaming system  1100  may include a gaming platform that establishes a portal for an end user to access a wagering game hosted by a game server  1106  through a user interaction server  1102 . The user device  1120  may communicate with a user interaction server  1102  of the gaming system  1100  using a network  1130  (e.g., the Internet). The user interaction server  1102  may communicate with the game server  1106  and provide game information to the user. In some embodiments, the game server  1106  may also be a game engine. In some embodiments, a single user device communicates with a game provided by the game server  1106 , while other embodiments may include a plurality of user devices  1120  configured to communicate and provide end users with access to the same game provided by the game server  1106 . In addition, a plurality of end users may be permitted to access a single user interaction server  1102 , or a plurality of user interaction servers  1102 , to access the game server  1106 . 
     The user interaction server  1102  may communicate with the user device  1120  to enable access to the gaming system  1100 . The user interaction server  1102  may enable a user to create and access a user account and interact with game server  1106 . The user interaction server  1102  may enable users to initiate new games, join existing games, and interface with games being played by the user. 
     The user interaction server  1102  may also provide a client  1122  for execution on the user device  1120  for accessing the gaming system  1100 . The client  1122  provided by the gaming system  1100  for execution on the user device  1120  can comprise a variety of implementations according to the user device  1120  and method of communication with the gaming system  1100 . In one embodiment, the user device  1120  connects to the gaming system  1100  using a web browser, and the client  1122  executes within a browser window or frame of the web browser. In another embodiment, the client  1122  is a stand-alone executable on the user device  1120 . 
     In one embodiment, the client  1122  may comprise a relatively small amount of script (e.g., JAVASCRIPT®), also referred to as a “script driver,” including scripting language that controls an interface of the client  1122 . The script driver may include simple function calls requesting information from the gaming system  1100 . In other words, the script driver stored in the client  1122  may merely include calls to functions that are externally defined by, and executed by, the gaming system  1100 . As a result, the client  1122  may be characterized as a “thin client.” As that term is used herein, the client  1122  may be little more than a script player. The client  1122  may simply send requests to the gaming system  1100  rather than performing logic itself. The client  1122  receives player inputs, and the player inputs are passed to the gaming system  1100  for processing and executing the wagering game. In one embodiment, this includes providing specific graphical display information to client  1122  as well as game outcomes. 
     In other embodiments, the client  1122  comprises an executable file rather than a script. In that case, client  1122  may do more local processing than does a script driver, such as calculating where to show what game symbols upon receiving a game outcome from game server  1106  through user interaction server  1102 . In one embodiment, it may be that portions of an asset server  1104  are loaded onto the client  1122  and are used by the client  1122  in processing and updating graphical displays. Due to security and integrity concerns, most embodiments will have the bulk of the processing of the game play performed in the gaming system  1100 . However, some embodiments may include significant game processing by client  1122  when the client and user device  1120  are considered trustworthy or when there is reduced concern for security and integrity in the displayed game outcome. In most embodiments, it is expected that some form of data protection, such as end-to-end encryption, will be used when data is transported over network  1130 . Network  1130  may be any network, including, but not limited to, the Internet. 
     In an embodiment where the client  1122  implements further logic and game control methodology beyond the thin client, the client  1122  may parse and define player interactions prior to passing the player interactions to the gaming system  1100 . Likewise, when the client  1122  receives a gaming interaction from the gaming system  1100 , the client  1122  may be configured to determine how to modify the display as a result of the gaming interaction. The client  1122  may also allow the player to change a perspective or otherwise interact with elements of the display that do not change aspects of the game. 
     The gaming system  1100  may include an asset server  1104 , which may host various media assets (e.g., audio, video, and image files) that may be sent to the client  1122  for presenting the various wagering games to the end user. In other words, in this embodiment, the assets presented to the end user may be stored separately from the client  1122 . In one embodiment, the client  1122  requests the assets appropriate for the game played by the user; in other embodiments, especially those using thin clients, just those assets that are needed for a particular display event will be sent by game server  1106  when the game server  1106  determines they are needed, including as few as one asset. In one example, the client  1122  may call a function defined at the user interaction server  1102  or asset server  1104 , which may determine which assets are to be delivered to the client  1122  as well as how the assets are to be presented by the client  1122  to the end user. Different assets may correspond to the various clients that may have access to the game server  1106  or to different games to be played. 
     The game server  1106  is configured to perform game play methods and determine game play outcomes that are provided to the user interaction server  1102  to be transmitted to the user device  1120  for display on the end user&#39;s computer. For example, the game server  1106  may include game rules for one or more wagering games, such that the game server  1106  controls some or all of the game flow for a selected wagering game as well as the determined game outcomes. The game server  1106  may include pay tables and other game logic. The game server  1106  also performs random number generation for determining random game elements of the wagering game. In one embodiment, the game server  1106  is separated from the user interaction server  1102  by a firewall or other method of preventing unauthorized access to the game server  1106  from the general members of the network  1130 . 
     The user device  1120  may present a gaming interface to the player and communicate the user interaction to the gaming system  1100 . The user device  1120  may be any electronic system capable of displaying gaming information, receiving user input, and communicating the user input to the gaming system  1100 . As such, the user device  1120  can be a desktop computer, a laptop, a tablet computer, a set-top box, a mobile device (including, but not limited to, a smart phone), a kiosk, a terminal, or another computing device. The user device  1120  operating the client  1122  may comprise an interactive electronic gaming system  800  (see  FIG. 11 ), as described above. The client  1122  may be a specialized application or may be executed within a generalized application capable of interpreting instructions from an interactive gaming system, such as a web browser. 
     The client  1122  may interface with an end user through a web page or an application that runs on a device including, but not limited to, a smartphone, a tablet, or a general computer, or the client  1122  may be any other computer program configurable to access the gaming system  1100 . The client  1122  may be illustrated within a casino webpage (or other interface) indicating that the client  1122  is embedded into a webpage, which is supported by a web browser executing on the user device  1120 . 
     In one embodiment, the gaming system  1100  may be operated by different entities. The user device  1120  may be operated by a third party, such as a casino or an individual, that links to the gaming system  1100 , which may be operated, for example, by a wagering game service provider. Therefore, in some embodiments, the user device  1120  and client  1122  may be operated by a different administrator than the operator of the game server  1106 . In other words, the user device  1120  may be part of a third-party system that does not administer or otherwise control the gaming system  1100  or game server  1106 . In another embodiment, the user interaction server  1102  and asset server  1104  are provided by a third-party system. For example, a gaming entity (e.g., a casino) may operate the user interaction server  1102  or user device  1120  to provide its customers access to game content managed by a different entity that may control game server  1106 , amongst other functionality. In some embodiments, these functions are operated by the same administrator. For example, a gaming entity (e.g., a casino) may elect to perform each of these functions in-house, such as providing both the access to the user device  1120  and the actual game content and providing administration of the gaming system  1100 . 
     The gaming system  1100  may communicate with one or more external account servers  1110 , optionally through another firewall. For example, the gaming system  1100  itself may not directly accept wagers or issue payouts. That is, the gaming system  1100  may facilitate online casino gaming but may not be part of a self-contained online casino itself. Instead, the gaming system  1100  may facilitate the play of wagering games owned and controlled by a company offering games and gaming products and services, such as Bally Gaming, Inc. Another entity (e.g., a casino or any account holder or financial system of record) may operate and maintain its external account servers  1110  to accept bets and make payout distributions. The gaming system  1100  may communicate with the account servers  1110  to verify the existence of funds for wagering and to instruct the account server  1110  to execute debits and credits. 
     In some embodiments, the gaming system  1100  may directly accept bets and make payout distributions, such as in the case where an administrator of the gaming system  1100  operates as a casino. As discussed above, the gaming system  1100  may be integrated within the operations of a casino rather than separating out functionality (e.g., game content, game play, credits, debits, etc.) among different entities. In addition, for play-for-fun wagering games, the gaming system  1100  may issue credits, take bets, and manage the balance of the credits according to the game outcomes, but the gaming system  1100  may not permit payout distributions or be linked to an account server  1110  that permits payout distributions. Such credits may be issued for free, through purchase, or for other reasons, without the ability for the player to cash out. Such play-for-fun wagering games may be administered on platforms that do not permit traditional gambling, such as to comply with jurisdictions that do not permit online gambling. 
     The gaming system  1100  may be configured in many ways, from a fully integrated single system to a distributed server architecture. The asset server  1104 , the user interaction server  1102 , the game server  1106 , and the account server  1110  may be configured as a single, integrated system of code modules running on a single server or machine, where each of the servers is functionally implemented on a single machine. In such a case, the functionality described herein may not be implemented as separate code modules. The asset server  1104 , the user interaction server  1102 , the game server  1106 , and the account server  1110  may also be implemented as a plurality of independent servers, each using its own code modules running on a separate physical machine, and may further include one or more firewalls between selected servers (depending on security needs). Each server could communicate over some kind of networked connection, potentially as varied as that described for network  1130 . Further, each single server may be implemented as a plurality of servers with load balancing and scalability factors built into the embodiment. All such embodiments and variations are fully contemplated. 
     Additional features may be supported by the game server  1106 , such as hacking and cheating detection, data storage and archival, metrics generation, messages generation, output formatting for different end user devices, as well as other features and operations. For example, the gaming system  1100  may include additional features and configurations as described in U.S. patent application Ser. No. 13/353,194, filed Jan. 18, 2012, and application Ser. No. 13/609,031, filed Sep. 10, 2012, both titled “Network Gaming Architecture, Gaming Systems, and Related Methods,” the disclosures of which are incorporated herein in their entirety by this reference. 
     The network  1130  may enable communications between the user device  1120  and the gaming system  1100 . A network (not shown) may also connect the gaming system  1100  and account server  1110 , and, further, one or more networks (not shown) may interconnect one or more of the other servers shown collectively as the gaming system  1100 . In one embodiment, the network  1130  uses standard communications technologies and/or protocols. Thus, the network  1130  can include links using technologies such as Ethernet, 802.11, worldwide interoperability for microwave access (WIMAX®), 3G, digital subscriber line (DSL), asynchronous transfer mode (ATM), INFINIBAND®, PCI Express Advanced Switching, etc. Similarly, the networking protocols used on the network  1130  can include multiprotocol label switching (MPLS), the transmission control protocol/Internet protocol (TCP/IP), the User Datagram Protocol (UDP), the hypertext transport protocol (HTTP), the simple mail transfer protocol (SMTP), the file transfer protocol (FTP), etc. The data exchanged over the network  1130  can be represented using technologies and/or formats including the hypertext markup language (HTML), the extensible markup language (XML), etc. In addition, all or some of the links can be encrypted using conventional encryption technologies such as secure sockets layer (SSL), transport layer security (TLS), virtual private networks (VPNs), Internet Protocol security (IPsec), etc. In another embodiment, the entities can use custom and/or dedicated data communications technologies instead of, or in addition to, the ones described above. Depending upon the embodiment, the network  1130  can include links comprising one or more networks such as the Internet. 
     In operation, an online gaming system may receive an instruction from a user device  1120  indicating a wager has been accepted in response to a player inputting an instruction to participate in a jackpot game. The player makes a wager that qualifies the player for at least play in a major jackpot. A random number is generated and a determination is made whether the game the player game station is eligible for a major progressive jackpot. In one example, the player game station is a virtual table game. The game is played, and if the game result is a predetermined winning major jackpot outcome, the player wins the major progressive jackpot.

     Referring to  FIG. 13 , illustrated is an example of a payout determination device (e.g., a spin wheel  1300 ) that may be used in conjunction with the progressive jackpot system  100  ( FIG. 1 ) and games that are played at tables using the progressive jackpot system  100  ( FIG. 1 ). In some embodiments, the spin wheel  1300  may include an animated representation of a wheel or a partial wheel. For example, the spin wheel  1300  may be similar to the spin wheel described in U.S. Pat. No. 8,535,141 to Rommerdahl et al., issued Sep. 17, 2013, the disclosure of which is incorporated herein in its entirety by this reference. The spin wheel  1300  may include a plurality of segments  1302 , a pointer  1304 , and SPIN button  1308 , any or all of which may be physically or virtually implemented (e.g., on a touchscreen or other display structure). Each segment  1302  of the plurality of segments  1302  may represent a potential prize  1306  (e.g., an award or payout). The pointer  1304  may be used to indicate a won prize  1306  after the spin wheel  1300  has been spun. In other embodiments, the payout determination device may include other types of value or number generating devices, such as dice, a spinning reel, roulette wheel, etc. 
     Referring to  FIGS. 9 and 13  together, in some embodiments, the spin wheel  1300  may be displayed on one or more of the player interface  916 , the upright display  930 , and the entire player surface  904 . In other embodiments, the spin wheel  1300  may have a separate dedicated display. For example, the spin wheel  1300  may be displayed on a display mounted to a table  900  at each player seat similar to the virtual button deck described in U.S. Pat. Pub. No. 2012/0108337, to Kelly et. al., published May 3, 2002, now U.S. Pat. No. 8,992,323, the disclosure of which is incorporated herein in its entirety by this reference. For purposes of the present disclosure, the spin wheel  1300  will be described as being displayed on the player interface  916 . However, the disclosure is not so limited, and it is understood that the spin wheel  1300  may be displayed on at least any of the above-described displays. In other embodiments, the spin wheel  1300  may include a mechanical spin wheel attached to the table  900 . 
     Referring to  FIGS. 1, 9, and 13  together, a player station  912  may be configured to display the spin wheel  1300  on the player interface  916  in response to an occurrence of a particular wagering game outcome. In other words, a player station  912  may be configured to display the spin wheel  1300  on the player interface  916  when a particular primary game (i.e. a game being administered at the table  900 ) outcome has occurred. Various primary game outcomes may trigger an opportunity for a winning player to spin the spin wheel  1300 . In some embodiments, a pay table for the primary game being administered at the table  900  may enable a player to spin the spin wheel  1300  when a player has achieved a certain win (e.g., the spin wheel  1300  acts to determine a prize in the pay table). For example, the player stations  912  may be configured to display the spin wheel  1300  to a player that has achieved one or more of a Three of a Kind, Straight, Flush, Full House, Four of a Kind, Straight Flush, and Royal Flush during primary game play the table  900 . For example, the spin wheel  1300  may be triggered by winning outcomes related to, for example, CARIBBEAN STUD® poker, ULTIMATE TEXAS HOLD &#39;EM®, Five-card stud poker, LET IT RIDE® poker. Furthermore, the spin wheel  1300  may be triggered by winning outcomes related to a wide variety of poker games, including poker games having three-card poker hands and poker games having five-card poker hands. Although the spin wheel  1300  is described herein as being triggered by a winning outcome related to Poker games, the disclosure is not so limited, and the spin wheel  1300  may be triggered by winning outcomes related to any game administered at a table  900  such as, for example, Baccarat, Roulette, Blackjack, etc. The opportunity to spin the spin wheel  1300  may be in addition to or an alternative of any payout given based on winning in the primary game. Therefore, the chance to trigger an opportunity to spin the spin wheel  1300  may add excitement to the current round and may encourage participation in the primary game of a table  900 . For example, a table  900  may advertise that the spin wheel  1300  is available in a current game to encourage participation in the current game. 
     In some embodiments, the spin wheel  1300  may not appear on the player interface  916  until a qualifying win has been achieved, and once the win has been achieved, the spin wheel  1300  will then appear on the player interface  916 . In other embodiments, the spin wheel  1300  may always be displayed on the player interface  916 . For example, the spin wheel  1300  may be displayed as a minimized and non-functional representation, and, upon achieving a qualifying win, the spin wheel  1300  may be maximized on the player interface  916  and made functional. The spin wheel  1300  may be minimized in a corner of the player interface  916  and may only be maximized when a player achieves a qualifying win. Thus, in such embodiments, the spin wheel  1300  may be displayed on the player interface  916  without previously being displayed or the spin wheel  1300  may be maximized from a minimized representation. 
     In some embodiments, the spin wheel  1300  a player will not be given an opportunity to spin the spin wheel  1300  (e.g., the spin wheel  1300  will not be displayed), even after achieving a qualifying win, unless the player has previously placed a side wager. For example, a side wager, specific to an opportunity to spin the spin wheel  1300 , may have to be placed by a player prior to engaging in primary game play at a table  900  (e.g., at a same time a primary or initial wager related to the primary game is placed by the player). In some embodiments, the side wager may be required to be of a certain value in order to qualify for a chance to spin the spin wheel  1300  should a qualifying win be achieved by the player. Referring to  FIGS. 1, 2, 9, and 13  together, in some embodiments, the side wager may be made after the eligibility of the table  900  for a major progressive jackpot  108  and/or a mega progressive jackpot  111  is determined according to the P(Eligibility) and P 2 (Eligibility), respectively, of the particular wagering game being administered at the table  900 . Therefore, knowledge that the current round of game play is eligible for the major progressive jackpot  108  and/or mega progressive jackpot  111  may add excitement to the current round, which may also encourage participation in the side wager. In other embodiments, the side wager may have to be placed before eligibility of the table  900  for the major progressive jackpot  108  and/or mega progressive jackpot  111  is determined. 
       FIGS. 14A through 14D  show example representations of spin wheels  1300  that may be displayed on a player interface  916  ( FIG. 9 ) of a player station  912  ( FIG. 9 ). In some embodiments, the plurality of segments  1302  of the spin wheel  1300  may be populated with prizes  1306  (e.g., segment values) based on the qualifying win achieved by a player. For example, prizes  1306  indicated in a plurality of segments  1302  of a spin wheel  1300  triggered by a qualifying win of Three of a Kind (e.g., as shown in  FIG. 14A ) may be different than prizes  1306  indicated in a plurality of segments  1302  of a spin wheel  1300  triggered by a qualifying win of a Full House (e.g., as shown in  FIG. 14D ). In some embodiments, the dealer may manually input which qualifying win has been achieved before the spin wheel  1300  will be populated with prizes  1306  related to the qualifying win. In other embodiments, the qualifying win may be automatically detected, and the spin wheel  1300  may be automatically populated with prizes  1306  related to the qualifying win. 
     In some embodiments, lower level qualifying wins (i.e., wins having a higher probability of occurring (e.g., Three of a Kind)) may result in the plurality of segments  1302  of the spin wheel  1300  being populated with smaller prizes  1306  (i.e., less valuable prizes), and higher level qualifying wins (i.e., wins having a lower probability of occurring (e.g., Royal Flush)) may result in the plurality of segments  1302  of the spin wheel  1300  being populated with larger prizes  1306  (i.e., more valuable prizes). In some embodiments, the prizes  1306 , with which a qualifying win populates the plurality of segments  1302 , may be at least partially determined based on a pay table of the primary game. For example, a pay table of the primary game may provide that a qualifying win of a Three of a Kind may normally pay 47 to 1, and a qualifying win of a Three of a Kind may result in the plurality of segments  1302  of the spin wheel  1300  being populated with prizes  1306  (e.g., excluding any segments  1302  having a jackpot) to provide an average weighted pay (i.e., total amount of prizes  1306  available in the plurality of segments  1302  divided by the number of segments  1302 ) of the plurality of segments  1302  of the spin wheel  1300  is still at least about 47 to 1. In other words, the prizes  1306  of the spin wheel  1300  may provide an average weighted pay substantially equal to the normal payout (e.g., within 1%, within 5%, within 10%). In other embodiments, the plurality of segments  1302  of the spin wheel  1300  may be populated with prizes  1306  including any segments  1302  having a jackpot such that an average weighted pay of the plurality of segments  1302  of the spin wheel  1300  is at least about equal to the normal payout of the qualifying win of a pay table of the primary game. For example, the current values of any jackpots included in the plurality of segments  1302  of the spin wheel  1300  may be considered prior to populating the other segments  1302  of the plurality of segments  1302 , and the other segments  1302  may be adjusted (e.g., populated) such that the average weighted pay of all of the segments  1302  of the plurality of segments  1302  is at least about equal to the normal payout of the qualifying win of the pay table of the primary game. Thus, in some embodiments, the prizes  1306  may be dependent on the size of the side wager and the qualifying win. Furthermore, amounts of the prizes  1306  may be inversely proportional to the probability of the prizes  1306  being selected (e.g., awarded or won). 
     The prizes  1306  may include one or more of credit amounts, set amounts, odds based amounts, or a number of free plays of the base game. In one or more embodiments, the prizes  1306  may be set amounts, i.e. non-progressive. In some embodiments, the algorithms to determine the amounts may be determined by a statistical percentage based on an average take of a gaming machine and the likelihood of the win over a period of time. In the case where one or more gaming machines are networked, a common pay table may be utilized where the prize algorithms are determined based on an average take (total wagers) of all the networked gaming machines and the likelihood of a win of a prize over a period of time. Each prize may be calculated in a similar manner based on the likelihood of a winning outcome being achieved during a game play session. 
     In some embodiments, at least one segment  1302  of the plurality of segments  1302  may include one or more jackpots. In some embodiments, the plurality of segments  1302  may include one or more progressive jackpots. The progressive jackpots included in the spin wheel  1300  may be a part of the progressive jackpot system  100  and may include one or more of local and multi-table progressive jackpots. For example, the plurality of segments  1302  may include one or more of the minor progressive jackpot  110 , major progressive jackpot  108 , and mega progressive jackpot  111 . In some embodiments, the plurality of segments  1302  may include 100% of the major progressive jackpot  108  and/or mega progressive jackpot  111 . In some embodiments, the plurality of segments  1302  may include only a portion (e.g., a percentage) of the major progressive jackpot  108  and/or mega progressive jackpot  111 . In some embodiments, the qualifying win must be of a certain level in order for the plurality of segments  1302  of a triggered spin wheel  1300  to include one or more of the minor progressive jackpot  110 , major progressive jackpot  108 , or mega progressive jackpot  111 . For example, a lower level qualifying win (e.g., a Three of a Kind) may not result in a spin wheel  1300  that includes one or more of the minor progressive jackpot  110 , major progressive jackpot  108 , or mega progressive jackpot  111 , and a higher level qualifying win (e.g., a Flush) may result in a spin wheel  1300  that includes one or more of the minor progressive jackpot  110 , major progressive jackpot  108 , or mega progressive jackpot  111 . As a result of the plurality of segments  1302  of the spin wheel  1300  potentially including jackpots, in some embodiments, the spin wheel  1300  may give a primary game access to jackpots where normal pay tables of the primary game do not give access to jackpots. 
     In some embodiments, a lower level qualifying win (e.g., a Three of a Kind) may trigger a spin wheel  1300  that includes only the minor progressive jackpot  110  and may not include the major progressive jackpot  108  or the mega progressive jackpot  111 . In other embodiments, a lower level qualifying win may trigger a spin wheel  1300  that includes only the minor progressive jackpot  110  and major progressive jackpot  108  and may not include the mega progressive jackpot  111 . In some embodiments, a higher level qualifying win (e.g., a Flush) may trigger a spin wheel  1300  that includes each of the minor progressive jackpot  110 , major progressive jackpot  108 , and mega progressive jackpot  111 . In other embodiments, a higher level qualifying win (e.g., a Royal Flush) may not trigger a spin wheel  1300  and may result in the player being awarded at least one of minor progressive jackpot  110 , major progressive jackpot  108 , and mega progressive jackpot  111  without spinning the spin wheel  1300 . 
     In some embodiments, whether or not the plurality of segments  1302  of a triggered spin wheel  1300  include one or more of the progressive jackpots may at least partially depend on the eligibility of the player station  912  (e.g., P(Eligible) and P 2 (Eligible)) of the player interface  916  on which the spin wheel  1300  is displayed. For example, even if a qualifying win would normally result in a spin wheel  1300  that includes one or more of the minor progressive jackpot  110 , major progressive jackpot  108 , and mega progressive jackpot  111 , if the player station  912  associated with the qualifying win is not currently eligible for a certain progressive jackpot, the spin wheel  1300  will not include the certain progressive jackpot. For example, as discussed above, a table  900  may only be eligible to participate in the major or mega progressive jackpots  108 ,  111  in a certain percentage of the number of games administered at the table  900 . Thus, if the progressive jackpot system  100  ( FIG. 1 ) has determined that the table  900  is not currently eligible for a progressive jackpot, the spin wheel  1300  will not include the progressive jackpot. 
     In some embodiments, the probability of the segments  1302  of the plurality of segments  1302  of the spin wheel  1300  having a jackpot being selected after the spin wheel  1300  is spun is determined by the progressive jackpot system  100 . Furthermore, the progressive jackpot system  100  ( FIG. 1 ) may maintain the P(MajorWin) and P(MegaWin), as previously described, even while utilizing the spin wheel  1300 . In other words, after normalization, a P(MajorWin) relating to a table  900  utilizing a spin wheel  1300  is at least substantially equal to a P(MajorWin) relating to a table  900  not utilizing a spin wheel  1300 . 
     For example, when relating to a table  900  utilizing a spin wheel  1300 ,
 
 P (MajorWin)= P (WheelMajorJackpotTrigger)* P (Eligible); and
 
 P (MegaWin)= P (WheelMegaJackpotTrigger)* P 2(Eligible).
 
     Furthermore, P(WheelMajorJackpotTrigger) may be equal to probability of achieving a particular winning game outcome P(WinningOutcome) multiplied by probability of a segment containing the major progressive jackpot  108  being selected P(MajorSegment) after the spin wheel  1300  is spun. Moreover, P(WheelMegaJackpotTrigger) may be equal to probability of achieving a particular winning game outcome P(WinningOutcome) multiplied by probability of a segment containing the mega progressive jackpot  111  being selected P(MegaSegment) after the spin wheel  1300  is spun. For example, the following example is provided to illustrate an embodiment of the progressive jackpot system  100  and spin wheel  1300  having four different winning outcomes linked to the same common major progressive jackpot  108  and mega progressive jackpot  111 . In this example, the first winning outcome is a Three of a Kind, the second winning outcome is a Straight, the third winning outcome is a Flush, and the fourth winning outcome is a Full House. 
     Examples of the probabilities of the winning outcomes in the primary game as discussed above are summarized in the following table:

     As a result, the winning outcome of a Three of a Kind may occur more frequently than the winning outcome of a Straight. The winning outcome of a Straight, however, may occur more frequently than the winning outcome of a Flush. The winning outcome of a Flush, however, may occur more frequently than the winning outcome of a Full House. The progressive jackpot system  100  may normalize the winning probabilities such that the overall probability for winning the mega progressive jackpot  111  and major progressive jackpot  108  is substantially equal for each winning outcome of an individual wagering game and for each player regardless of which wagering game or at which table  900  they are playing. 
     Due to the differences in probabilities of different winning outcomes, the probabilities of segments  1302  containing a progressive jackpot being selected P(MajorSegment) and P(MegaSegment) may be adjusted to compensate such that the P(WheelMajorJackpotTrigger) of each winning outcome is at least substantially the same and the P(WheelMegaJackpotTrigger) of each winning outcome is at least substantially the same. The probabilities of segments  1302  being selected containing a major progressive jackpot  108  P(MajorSegment) are summarized in the following table:

     Thus, regardless of which winning outcome is achieved, the probability of a winning outcome leading to winning the mega progressive jackpot  111  P(WheelMegaJackpotTrigger) is the same. Because the P(WheelMajorJackpotTrigger) is the same for each winning outcome and because the P(WheelMegaJackpotTrigger) is the same for each winning outcome, P(MajorWin) and P(MegaWin) may be normalized in the same manner as discussed above by, for example, adjusting the eligibility probabilities P(Eligible) and P 2 (Eligible) such that, after normalization:
 
 P (MegaWin A )≈ P (MegaWin B )≈ P (MegaWin C ); and
 
 P (MajorWin A )≈ P (MajorWin B )≈ P (MajorWin C ).
 
     Any other progressive jackpots included in the spin wheel  1300  may behave in the same manner as the mega and major progressive jackpots  111 ,  108 , as described above. 
     Referring to  FIGS. 9, 13, and 14A through 14D  together, in operation, once the spin wheel  1300  has appeared on the player interface  916 , various controls/buttons on the player station  912  or player interface  916  may be used to spin the spin wheel  1300 . In some embodiments, a player may spin the spin wheel  1300  by pressing the SPIN button  1308 . The SPIN button  1308  may be displayed on the player interface  916  along with the spin wheel  1300  and may include a touch screen button. In other embodiments, the SPIN button  1308  may be separate from the player interface and may be located elsewhere on the gaming machine. The spin wheel  1300  may be configured to spin and stop in predetermined stop positions in response to the player pressing the SPIN button  1308 . 
     In other embodiments, a player may spin the spin wheel  1300  by touching and dragging a finger on the surface of the spin wheel  1300  (i.e., representation of the spin wheel  1300  displayed on the player interface  916 ). The player may move and spin the spin wheel  1300  at a variety of speeds and in either direction of rotation. A wheel spin speed may be based on the distance from where the player initially touches the spin wheel  1300  and removes his finger when moving in a same direction. In this manner, a player moving his finger tangentially to an axis of the spin wheel  1300  will produce a greater rotational spin wheel speed, the closer his finger is to a center of the spin wheel  1300 , due to there being a higher rotational velocity than if the player had moved his finger at the same speed farther away from the center of the spin wheel  1300 . The distance traveled and the rate of travel is used to determine a relative initial spin wheel velocity. 
     In some embodiments, the player may “cock” the spin wheel  1300  by spinning it slightly counterclockwise before starting it in motion with a clockwise finger swipe, or vice-versa. Once the spin wheel  1300  starts to spin and the player&#39;s finger is removed from a surface of the player interface  916 , the spin wheel  1300  gradually slows down from its initial spin rate until a segment  1302  of the plurality of segments  1302  of the spin wheel  1300  stops adjacent to pointer  1304 . The prize  1306  in the segment adjacent to the pointer is then paid out to the player.
