     BACKGROUND 
     Gaming machines which provide players awards in primary or base games are well known. Gaming machines generally require the player to place or make a wager to activate the primary or base game. In many of these gaming machines, the award is based on the player obtaining a winning symbol or symbol combination and on the amount of the wager (e.g., the higher the wager, the higher the award). Generally, symbols or symbol combinations which are less likely to occur usually provide higher awards. 
     Gaming machines which provide secondary or bonus games are also known. The secondary or bonus games usually provide an additional award, such as a bonus award, to the player. Secondary or bonus games usually do not require an additional wager by the player to be activated. Instead, secondary or bonus games are generally activated or triggered upon an occurrence of a designated triggering symbol or triggering symbol combination in the primary or base game. For instance, a bonus symbol occurring on the payline on the third reel of a three reel slot machine may trigger the secondary bonus game. When a secondary or bonus game is triggered, the gaming machine generally indicates this triggering to the player through one or more visual and/or audio output devices, such as the reels, lights, speakers, video screens, etc. Part of the enjoyment and excitement of playing certain gaming machines is the occurrence or triggering of the secondary or bonus game (even before the player knows how much the bonus award will be). 
     Progressive awards associated with gaming machines are also known. In one form, a progressive award is an award amount which includes an initial amount funded by a casino and an additional amount funded through a portion of each wager made on the progressive gaming machine. For example, 0.1% of each wager placed on the primary game of the gaming machine associated with the progressive award may be allocated to the progressive award or progressive award fund or pool. The progressive award grows in value as more players play the gaming machines and more portions of these players&#39; wagers are allocated to the progressive award. When a progressive award triggering event occurs, such as when a player obtains a winning symbol combination associated with the progressive award or when the progressive award grows to a progressive award hit value, the accumulated progressive award is provided to the player. After the progressive award is provided to the player, the amount of the next progressive award is reset to the initial value and a portion of each subsequent wager on a gaming machine associated with the progressive award is allocated to the next progressive award. 
     While such progressive awards are popular amongst players, a number of issues exist with these known progressive award systems. First, only players currently playing gaming machines in the progressive award gaming system are typically eligible to win the progressive award. Typically, in such progressive award systems, the player who places the wager that caused the progressive award system to meet the specified criteria (such as an amount of coin-in) is awarded the progressive award. Thus, if a player stops playing for the progressive award, the player sacrifices their opportunity to win the progressive award and the progressive award may be provided to another player. This may discourage certain players from playing a gaming machine if they have a limited amount of time to play. 
     In one instance, certain players leave the gaming machines after realizing that the progressive award has been provided to another player. Such players may walk away from the gaming machines feeling discouraged. Such discouragement can lead to certain players walking away with jackpot fatigue. By walking away, even if the player has spent long periods of time playing for the progressive award, the player sacrifices or forfeits any opportunity to win the progressive award. This may lead to certain players feeling pessimistic about their chances to win the progressive award. 
     Other players may believe that a significant amount of time and money are required to win the progressive award. This may discourage certain players from playing a gaming machine, especially if those players have a limited amount of money to play with or a limited amount of time to play. 
     There is a continuing need to provide new and different gaming machines and gaming systems which addresses these issues as well as new and different ways to provide awards to players including progressive awards and other bonus awards. 
     SUMMARY 
     The present disclosure relates generally to gaming systems and methods for providing a plurality of awards to a plurality of players upon an occurrence of a bonus event. 
     In various embodiments, the gaming system disclosed herein includes a bonus event associated with a bonus event time period or bonus event time window. The bonus event utilizes a plurality of bonus event component sequences, wherein each bonus event component sequence is associated with a plurality of time periods or windows which collectively (when accounting for any overlaps) forms the bonus event time period. In these embodiments, upon the triggering of the bonus event, the gaming system provides one or more awards in association with each bonus event component sequence. That is, for the single occurrence of a bonus event triggering event, the gaming system determines a plurality of winners for a plurality of different time periods that are each associated with the bonus event. Such a configuration of providing a plurality of awards over a plurality of time periods based on a single occurrence of a triggering event combats jackpot fatigue and provides an increased amount of excitement and enjoyment for certain players. 
     More specifically, in certain embodiments, the gaming system enables a plurality of players at a plurality of electronic gaming machines to place one or more wagers on one or more games. In these embodiments, upon an occurrence of a bonus event triggering condition, the gaming system triggers a bonus event. In certain embodiments, a bonus event triggering condition is satisfied independent of any displayed event associated with any plays of any games, such as in response to a tracked amount of coin-in reaching a threshold amount. In certain other embodiments, a bonus event triggering condition is satisfied based on a displayed event associated with a play of a game, such as the generation of a designated winning symbol combination. 
     In these embodiments, the triggered bonus event includes a plurality of individual bonus event component sequences. Each individual bonus event component sequence is associated with a plurality of time periods or windows including: (i) a bonus award ineligibility time period or window during which any wagers placed on any plays of any games by any players are not utilized to determine which players win any bonus awards, and (ii) a bonus award eligibility time period or window during which one or more wagers placed on one or more plays of one or more games by one or more players are utilized, at least in part, to determine which players win any bonus awards. 
     In certain embodiments, the bonus award eligibility time period of at least one bonus event component sequence at least partially overlaps with the bonus award ineligibility period of another bonus event component sequence such that a plurality of bonus event component sequences are simultaneously or concurrently activated. That is, prior to the conclusion of the bonus award eligibility time period for one or more bonus event component sequences, the gaming system triggers or activates the bonus award ineligibility time period for another bonus event component sequence such that at least two bonus event component sequences are overlappingly activated. Such a configuration provides that at at least one point in time of the bonus event, one or more wagers placed by one or more players are being accounted for in association with at least two different bonus event component sequences. 
     Following the satisfaction of a bonus event triggering condition, the gaming system activates or initiates a first bonus event component sequence of the triggered bonus event. For the activated first bonus event component sequence, the gaming system first initiates a bonus award ineligibility time period or window (i.e., an attract time window). During this bonus award ineligibility time period, the gaming system enables a plurality of players at a plurality of electronic gaming machines to place one or more wagers on one or more games In one such embodiment, these wagers contribute to the bonus award of the first bonus event component sequence, but are not utilized in determining which players win any bonus event awards associated with the activated bonus event component sequence. That is, while the wagers placed by the players at the electronic gaming machines during the attract time window of the activated bonus event component sequence are not employed to determine which player wins a bonus event award for that activated bonus event component sequence, the wagers placed by the players at the electronic gaming machines during the attract time window of the activated bonus event component sequence are employed to grow the bonus event award for that activated bonus event component sequence. 
     Following the conclusion of the bonus award ineligibility time period or window for the activated first bonus event component sequence, the gaming system initiates a bonus award eligibility time period or window (i.e., a winning time window). During this bonus award eligibility time period, the gaming system enables a plurality of players at a plurality of electronic gaming machines to place one or more wagers on one or more games, wherein such wagers contribute to the bonus award of the first bonus event component sequence and are utilized in determining which players win any bonus event awards associated with the activated bonus event component sequence. That is, the wagers placed by the players at the electronic gaming machines during the winning time window of the activated bonus event component sequence are employed to: (i) determine which player wins a bonus event award for that activated bonus event component sequence, and (ii) grow the bonus event award for that activated bonus event component sequence. 
     Following the conclusion of the bonus award eligibility time period, the gaming system selects one or more of the electronic gaming machines to provide one or more bonus event awards associated with the activated bonus event component sequence. In certain embodiments, the selection of the electronic gaming machine(s) to provide such bonus event award(s) occurs based on a displayed event associated with a play of a game. In certain other embodiments, the selection of the electronic gaming machine(s) to provide such bonus event award(s) occurs independent of any displayed event associated with any plays of any games. In one such embodiment, the gaming system determines which electronic gaming machine to select to provide a bonus event award to based on the respective relative total amounts wagered on each of the electric gaming machines during the bonus award eligibility time period of that bonus event component sequence. In this embodiment, for a bonus event component sequence, the gaming system determines the relative percentages of total amounts wagered for each of the electronic gaming machines by determining the amount wagered at each electronic gaming machine in relation to the total amount wagered at all electronic gaming machines during the bonus award eligibility time period for that bonus event component sequence. In this embodiment, the gaming system uses these relative percentages determined for each electronic gaming machine to randomly determine which of the electronic gaming machines will be selected to provide the bonus event award(s) for the activated bonus event component sequence. Accordingly, each electronic gaming machine associated with the placement of a designated wager amount on one or more plays of one or more games during the bonus award eligibility time period has a chance of being selected to provide a bonus award for the activated bonus event component sequence. It should be appreciated that in this embodiment, the electronic gaming machine which had the most amount wagered during the bonus award eligibility time period has the greatest relative percentage of total amounts wagered and thus has the highest chance of being selected to provide a bonus award for the activated bonus event component sequence. 
     Following providing one or more players one or more awards for the activated bonus event component sequence, the gaming system determines whether any other bonus event component sequences are currently activated (i.e., as a result of the above-described overlapping of the time periods of at least two bonus event component sequences) or remain to be activated. 
     If at least one other bonus event component sequence is currently activated, the gaming system proceeds with providing one or more players one or more awards for that activated bonus event component sequence as described above. If at least one bonus event component sequence remains to be activated (i.e., at least one bonus event component sequence of the triggered bonus event has not been previously activated by the gaming system), the gaming system activates the bonus award ineligibility time period of the remaining bonus event component sequence and proceeds with providing one or more players one or more awards for that bonus event component sequence as described above. On the other hand, if no bonus event component sequences remain inactivated (i.e., each of the bonus event component sequences of the triggered bonus event have concluded), the gaming system concludes the triggered bonus event and awaits for another triggering of another bonus event. 
     Accordingly, the gaming system and method disclosed herein enables a plurality of players to individually win one or more awards based on the occurrence of a single bonus event triggering event. Such a configuration increases the amount of excitement and enjoyment of certain players by providing these players the chance to win one or more bonus event awards regardless of whether these players are playing at the electronic gaming machine associated with the triggering of the bonus event. 
     Additional features and advantages are described in, and will be apparent from, the following Detailed Description and the figures.

     DETAILED DESCRIPTION 
     Multiple Winner Bonus Event 
     In various embodiments, the gaming system disclosed herein includes a bonus event associated with a bonus event time period or bonus event time window. The bonus event utilizes a plurality of bonus event component sequences, wherein each bonus event component sequence is associated with a plurality of time periods or windows which collectively (when accounting for any overlaps) forms the bonus event time period. In these embodiments, upon the triggering of the bonus event, the gaming system provides one or more awards in association with each bonus event component sequence. That is, for the single occurrence of a bonus event triggering event, the gaming system determines a plurality of winners for a plurality of different time periods that are each associated with the bonus event. Such a configuration of providing a plurality of awards over a plurality of time periods based on a single occurrence of a triggering event combats jackpot fatigue and provides an increased amount of excitement and enjoyment for certain players. 
     While the player&#39;s credit balance, the player&#39;s wager, and any awards are displayed as an amount of monetary credits or currency in certain of the embodiments described below, one or more of such player&#39;s credit balance, such player&#39;s wager, and any awards provided to such a player may be for non-monetary credits, promotional credits, and/or player tracking points or credits. 
     Referring now to  FIG. 1 , a flowchart of an example embodiment of a process for operating a gaming system disclosed herein is illustrated. In one embodiment, this process is embodied in one or more software programs stored in one or more memories and executed by one or more processors or servers. Although this process is described with reference to the flowchart illustrated in  FIG. 1 , it should be appreciated that many other methods of performing the acts associated with this process may be used. For example, the order of certain steps described may be changed, or certain steps described may be optional. 
     In operation of one embodiment of the gaming system disclosed herein, in addition to: (i) enabling one or more players to wager on one or more games (not shown), (ii) for each game played, generating and displaying an outcome (not shown), and (iii) for each game played, determining and displaying any award associated with the displayed outcome (not shown), upon the satisfaction of a bonus event triggering condition, the gaming system triggers a bonus event as indicated in block  102 . 
     In one embodiment, a bonus event triggering condition is satisfied based on a displayed event in a play of one or more displayed games. In another embodiment, the gaming system tracks the occurrences of one or more suitable events occurring at or in association with one or more players and/or one or more games and determines, based on these tracked events, whether a bonus event triggering condition is satisfied. In another embodiment, the gaming system defines one or more game play parameters, wherein each time a player&#39;s tracked game play activity satisfies the defined parameter, the bonus event triggering condition is satisfied. 
     In another embodiment, a bonus event triggering condition is satisfied independent of any displayed event in any play of any game. In one such embodiment, the gaming system maintains a wager accumulation pool, wherein the gaming system allocates a portion of each wager placed (or each designated wager placed) to the maintained wager accumulation pool. In one such embodiment, the gaming system determines that a bonus event triggering condition is satisfied when the gaming system determines that the current value of the maintained wager accumulation pool has incremented to a wager accumulation pool trigger value or hit value. In another such embodiment, the gaming system determines that a bonus event triggering condition is satisfied when the gaming system determines that the current value of the maintained wager accumulation pool has incremented to within a suitable range of the wager accumulation pool trigger value or hit value. 
     In one embodiment, as further indicated in block  102 , the triggered bonus event includes a plurality of individual bonus event component sequences. In this embodiment, each individual bonus event component sequence is associated with a plurality of time periods or windows including: (i) a bonus award ineligibility time period or window, and (ii) a bonus award eligibility time period or window. In one example, as seen in  FIG. 2 , a triggered bonus event includes a first individual bonus event component sequence  202   a  and a second individual bonus event component sequence  202   b . As seen in this example, the first bonus event component sequence includes a bonus award ineligibility time period  204   a  of ten seconds and a bonus award eligibility time period or window  206   a  of ten seconds. As further seen in this example, the second bonus event component sequence includes a bonus award ineligibility time period  204   b  of ten seconds and a bonus award eligibility time period or window  206   b  of ten seconds. 
     Returning to  FIG. 1 , following the triggering of the bonus event, the gaming system initiates or activates, at designated intervals, the bonus award ineligibility time periods of each of the bonus event component sequences of the triggered bonus event as indicated in block  104 . That is, as the triggered bonus event is associated with a period of time and as the triggered bonus event includes a plurality of bonus event component sequences, the gaming system periodically activates the bonus event component sequences (and specifically periodically activates the bonus award ineligibility time periods of the bonus event component sequences) such that the triggered bonus event continues for the associated period of time. 
     In certain embodiments, the initiation or activation, at designated intervals, of the bonus award ineligibility time periods of each of the bonus event component sequences of the triggered bonus event provides that the bonus award eligibility time period of at least one bonus event component sequence at least partially overlaps with the bonus award ineligibility period of another bonus event component sequence. Put differently, this periodic initiation or activation of the bonus award ineligibility time periods of each of the bonus event component sequences of the triggered bonus event causes a plurality of bonus event component sequences to be simultaneously, concurrently or overlappingly activated. Such a configuration provides that at at least one point in time of the bonus event, one or more wagers placed by one or more players are being accounted for in association with at least two different bonus event component sequences. 
     For example, as seen in  FIG. 2 , for the triggered bonus event, the last five seconds of the bonus award eligibility time period or window  206   a  of the first bonus event component sequence  202   a  overlaps with the first five seconds of the bonus award ineligibility time period  204   b  of the second bonus event component sequence  202   b . It should be appreciated that while this example includes bonus award ineligibility time periods of ten seconds, bonus award eligibility time periods of ten seconds and a five second overlap between time periods of different bonus event component sequences, any suitable amount of time of such time periods and/or such overlaps may be implemented in accordance with the present disclosure. It should be further appreciated that while this example includes bonus award ineligibility time periods and bonus award eligibility time periods of the same duration, different bonus award ineligibility time periods and/or different bonus award eligibility time periods may be of different durations. 
     In certain embodiments, during the bonus award ineligibility time period of a bonus event component sequence (i.e., during an attract time period), any wagers placed on any plays of any games by any players are not utilized to determine which players win any bonus awards. In one such embodiment, the gaming system utilizes any wagers placed on any plays of any games by any players during the bonus award ineligibility time period of a bonus event component sequence to fund one or more bonus event awards. In this embodiment, one or more wagers placed on one or more games during the bonus award ineligibility time period of a bonus event component sequence contribute to the bonus award of the initiated bonus event component sequence, but are not utilized in determining which players win any bonus event awards associated with the activated bonus event component sequence. That is, while the wagers placed by the players during the attract time window of the bonus event component sequence are not employed to determine which player wins a bonus event award for that bonus event component sequence, the wagers placed by the players during the attract time window of the bonus event component sequence are employed to grow the bonus event award. 
     Following the initiation of the bonus award ineligibility time period of one of the bonus event component sequences of the triggered bonus event, the gaming system determines, for each initiated bonus event component sequence, whether the initiated bonus award ineligibility time period has concluded as indicated in diamond  106 . 
     If the gaming system determines that the initiated bonus award ineligibility time period has not concluded, the gaming system returns to diamond  106  and continues with determining, at designated intervals, whether the initiated bonus award ineligibility time period has concluded. On the other hand, if the gaming system determines that the initiated bonus award ineligibility time period has concluded, as indicated in block  108 , the gaming system initiates the bonus award eligibility time period of the same bonus event component sequence as the concluded bonus award ineligibility time period. 
     In certain embodiments, during the bonus award eligibility time period of a bonus event component sequence (i.e., during a winning time period), any wagers placed on any plays of any games by any players are utilized to determine which players win any bonus awards. In one such embodiment, the gaming system utilizes any wagers placed on any plays of any games by any players during the bonus award eligibility time period of a bonus event component sequence to fund one or more bonus event awards. In this embodiment, one or more wagers placed on one or more games during the bonus award eligibility time period of a bonus event component sequence contribute to the bonus award of the initiated bonus event component sequence and are further utilized in determining which players win any bonus event awards associated with the activated bonus event component sequence. That is, the wagers placed by the players during the winning time window of the bonus event component sequence are employed to determine which player wins a bonus event award for that bonus event component sequence and are employed to grow the bonus event award. 
     Following the initiation of the bonus award eligibility time period of one of the bonus event component sequences of the triggered bonus event, the gaming system determines, for each initiated bonus event component sequence whether the initiated bonus award eligibility time period has concluded as indicated in diamond  110 . 
     If the gaming system determines that the initiated bonus award eligibility time period has not concluded, the gaming system returns to diamond  110  and continues with determining, at designated intervals, whether the initiated bonus award eligibility time period has concluded. On the other hand, if the gaming system determines that the initiated bonus award eligibility time period has concluded, as indicated in block  112 , the gaming system selects which player(s) to provide the bonus event award associated with the initiated bonus event component sequence. 
     In one embodiment, the gaming system determines which player(s) to provide the bonus event award associated with the initiated bonus event component sequence based on a displayed event in a play of one or more displayed games. In another embodiment, the gaming system tracks the occurrences of one or more suitable events occurring at or in association with one or more players and/or one or more games and determines, based on these tracked events, which player(s) to provide the bonus event award associated with the initiated bonus event component sequence. In another embodiment, the gaming system defines one or more game play parameters, wherein the gaming system determines which player(s) to provide the bonus event award associated with the initiated bonus event component sequence based on a player&#39;s tracked game play activity satisfying the defined parameter. 
     In another embodiment, the gaming system determines which player(s) to provide the bonus event award associated with the initiated bonus event component sequence independent of any displayed event in any play of any game. In one such embodiment, the gaming system determines which player(s) to provide the bonus event award associated with the initiated bonus event component sequence based on the respective relative total amounts wagered on each of the electric gaming machines during the bonus award eligibility time period of that bonus event component sequence. In this embodiment, for a bonus event component sequence, the gaming system determines the relative percentages of total amounts wagered for each of the electronic gaming machines by determining the amount wagered at each electronic gaming machine in relation to the total amount wagered at all electronic gaming machines during the bonus award eligibility time period for that bonus event component sequence. In this embodiment, the gaming system uses these relative percentages determined for each electronic gaming machine to randomly determine which of the electronic gaming machines will be selected to provide the bonus event award(s) for the activated bonus event component sequence. 
     For example, as seen in  FIG. 3 , (i) electronic gaming machine A wagered two-hundred-twenty credits during the bonus award eligibility time period of the bonus event component sequence, (ii) electronic gaming machine B wagered one-hundred-fifty-four credits during the bonus award eligibility time period of the bonus event component sequence, and (iii) electronic gaming machine B wagered sixty-six credits during the bonus award eligibility time period of the bonus event component sequence. In this example, based on the total of four-hundred-forty credits being wagered during the bonus award eligibility time period of the bonus event component sequence, the gaming system determines: (i) electronic gaming machine A has a 50% (or 220/440) of being selected to win the bonus event award of the bonus event component sequence, (ii) electronic gaming machine B has a 35% (or 154/440) of being selected to win the bonus event award of the bonus event component sequence, and (iii) electronic gaming machine C has a 15% (or 66/440) of being selected to win the bonus event award of the bonus event component sequence. In this example, the gaming system determines the electronic gaming machine to provide the bonus event award of the bonus event component sequence based on these probabilities using a random number generator or random number generating algorithm. 
     As seen in this example, each electronic gaming machine associated with the placement of a designated wager amount on one or more plays of one or more games during the bonus award eligibility time period has a chance of being selected to provide a bonus award for the activated bonus event component sequence. As further seen in this example, the electronic gaming machine which had the most amount wagered during the bonus award eligibility time period has the greatest relative percentage of total amounts wagered and thus has the highest chance of being selected to provide a bonus award for the activated bonus event component sequence. 
     It should be appreciated that, as described above, the credits wagered during the bonus event ineligibility time period of a bonus event component sequence are not employed to determine each player&#39;s probability of winning a bonus award. For example, as seen in  FIG. 3 , while Player B had the most amount of credits wagered during the bonus event ineligibility time period (and the most amount of credits wagered during the total time period of this bonus event component sequence), since only the credits wagered during the bonus event eligibility time period are utilized in this example, Player B did not have the highest relative probability of winning a bonus award for this bonus event component sequence. 
     Returning to  FIG. 1 , following the determination of which player(s) to provide the bonus event award associated with the initiated bonus event component sequence, the gaming system provides the bonus event award to the selected player and concludes the initiated bonus event component sequence as indicated in blocks  114  and  116 . 
     In one embodiment, the gaming system provides the same bonus award (or bonus awards within a designated range) for each bonus event component sequence. In one such embodiment, the gaming system maintains a bonus event award, such as a progressive award, wherein the gaming system provides the same portion (or portions within a designated range) of the maintained bonus event award for each bonus event component sequence. In another embodiment, the gaming system provides different bonus awards for two or more bonus event component sequences. In one such embodiment, the gaming system maintains a bonus event award, such as a progressive award, wherein the gaming system provides different portions of the maintained bonus event award for at least two bonus event component sequences. For example, the player selected to win the bonus award of a first bonus event component sequence is provided 40% of the bonus event award and the player selected to win the bonus award of a second bonus event component sequence is provided 60% of the bonus event award. 
     In different embodiments, the bonus award(s) provided in association with one or more bonus event component sequences include one or more of: a quantity of monetary credits, a quantity of non-monetary credits, a quantity of promotional credits, a quantity of player tracking points, a progressive award, a modifier, such as a multiplier, a quantity of free plays of one or more games, a quantity of plays of one or more secondary or bonus games, a multiplier of a quantity of free plays of a game, one or more lottery based awards, such as lottery or drawing tickets, a wager match for one or more plays of one or more games, an increase in the average expected payback percentage for one or more plays of one or more games, one or more comps, such as a free dinner, a free night&#39;s stay at a hotel, a high value product such as a free car, or a low value product such as a free teddy bear, one or more bonus credits usable for online play, a lump sum of player tracking points or credits, a multiplier for player tracking points or credits, an increase in a membership or player tracking level, one or more coupons or promotions usable within and/or outside of the gaming establishment (e.g., a 20% off coupon for use at a convenience store), virtual goods associated with the gaming system, virtual goods not associated with the gaming system, an access code usable to unlock content on an internet. 
     In another embodiment, the bonus award(s) provided in association with one or more bonus event component sequences includes triggering or unlocking one or more features otherwise unavailable to the player. In different embodiments, the gaming system selects such feature(s) from the group of features including, but not limited to:
         (i) a book-end wild symbols feature;   (ii) a stacked wild symbols feature;   (iii) an expanding wild symbols feature;   (iv) a wild reel feature;   (v) a retrigger symbol feature;   (vi) an anti-terminator symbol feature;

  (xxi) a modification of a wager placed on one or more ways to win (or on one or more designated ways to win);   (xxii) a modification of a paytable utilized for a play of a game;   (xxiii) an application of a modifier, such as a multiplier or an additional quantity of credits, to one or more awards of a paytable utilized for a play of a game,   (xxiv) a modification of an average expected payback percentage of a play of a game;   (xxv) a modification of an average expected payout of a play of a game;   (xxvi) a modification of one or more awards available;   (xxvii) a modification of a range of awards available;   (xxviii) a modification of a type of awards available;   (xxix) a modification of one or more progressive awards;   (xxx) a modification of which progressive awards are available to be won;   (xxxi) a modification of one or more modifiers, such as multipliers, available;   (xxxii) a modification of an activation of a reel (or a designated reel);   (xxxiii) a modification of an activation of a plurality of reels;   (xxxiv) a modification of a generated outcome (or a designated generated outcome);

     Returning to  FIG. 1 , following the conclusion of the bonus event component sequence, the gaming system determines whether the concluded bonus event component sequence is a final bonus event component sequence of the triggered bonus event as indicated in diamond  118 . 
     If the concluded bonus event component sequence is not the final bonus event component sequence of the triggered bonus event, the gaming system returns to block  104  and awaits the periodic initiation or activation of another bonus award ineligibility time period of another bonus event component sequence of the triggered bonus event. That is, if at least one bonus event component sequence of the triggered bonus event remains unplayed, the gaming system awaits for another bonus event component sequence of the triggered bonus event to be played. On the other hand, if the concluded bonus event component sequence is the final bonus event component sequence of the triggered bonus event, the gaming system concludes the triggered bonus event as indicated in block  120 . 
     In one embodiment, the gaming system causes at least one display device of at least one electronic gaming machine to display the triggered bonus event. In another embodiment, in addition or in alternative to each electronic gaming machine displaying the triggered bonus event, the gaming system causes one or more community or overhead display devices to display part or all of the triggered bonus event to one or more other players or bystanders either at a gaming establishment or viewing over a network, such as the internet. In another embodiment, in addition or in alternative to each electronic gaming machine displaying the triggered bonus event, the gaming system causes one or more internet sites to each display the triggered bonus event such that a player is enabled to log on from a personal web browser. In another such embodiment, the gaming system enables the player to play one or more games on one device while viewing the triggered bonus event from another device, such as a desktop or laptop computer. 
     In different embodiments, a bonus event triggering condition is satisfied, one or more bonus award ineligibility time periods of one or more bonus event component sequences are initiated and/or concluded, one or more bonus award eligibility time periods of one or more bonus event component sequences are initiated and/or concluded, and/or one or more players are selected to be provided one or more bonus awards of one or more bonus event component sequences, based on an outcome associated with one or more plays of any primary game and/or an outcome associated with one or more plays of any secondary game of the electronic gaming machines in the gaming system. In one embodiment, such determinations are symbol driven based on the generation of one or more designated symbols or symbol combinations. In various embodiments, a generation of a designated symbol (or sub-symbol) or a designated set of symbols (or sub-symbols) over one or more plays of a primary game causes such conditions to be satisfied and/or one or more of such events to occur. 
     In different embodiments, the gaming system does not provide any apparent reasons to the players for the satisfaction of a bonus event triggering condition, the initiation and/or conclusion of one or more bonus award ineligibility time periods of one or more bonus event component sequences, the initiation or conclusion of one or more bonus award eligibility time periods of one or more bonus event component sequences and/or the selection of one or more players to be provided one or more bonus awards of one or more bonus event component sequences. In these embodiments, such determinations are not triggered by an event in a primary game or based specifically on any of the plays of any primary game or on any of the plays of any secondary game of the electronic gaming machines in the system. That is, these conditions are satisfied and these events occur without any explanation or alternatively with simple explanations. 
     In one such embodiment, a bonus event triggering condition is satisfied, one or more bonus award ineligibility time periods of one or more bonus event component sequences are initiated and/or concluded, one or more bonus award eligibility time periods of one or more bonus event component sequences are initiated and/or concluded, and/or one or more players are selected to be provided one or more bonus awards of one or more bonus event component sequences based on an amount of coin-in. In this embodiment, the gaming system determines if an amount of coin-in wagered reaches or exceeds a designated amount of coin-in (i.e., a threshold coin-in amount). Upon the amount of coin-in wagered reaching or exceeding the threshold coin-in amount, the gaming system causes one or more of such events or conditions to occur. In another such embodiment, a bonus event triggering condition is satisfied, one or more bonus award ineligibility time periods of one or more bonus event component sequences are initiated and/or concluded, one or more bonus award eligibility time periods of one or more bonus event component sequences are initiated and/or concluded, and/or one or more players are selected to be provided one or more bonus awards of one or more bonus event component sequences based on an amount of virtual currency-in. In this embodiment, the gaming system determines if an amount of virtual currency-in wagered reaches or exceeds a designated amount of virtual currency-in (i.e., a threshold virtual currency-in amount). Upon the amount of virtual currency-in wagered reaching or exceeding the threshold virtual currency-in amount, the gaming system causes one or more of such events or conditions to occur. In different embodiments, the threshold coin-in amount and/or the threshold virtual currency-in amount is predetermined, randomly determined, determined based on a player&#39;s status (such as determined through a player tracking system), determined based on a generated symbol or symbol combination, determined based on a random determination by the central controller, determined based on a random determination at the gaming device, determined based on one or more side wagers placed, determined based on the player&#39;s primary game wager, determined based on time (such as the time of day) or determined based on any other suitable method or criteria. 
     In one such embodiment, a bonus event triggering condition is satisfied, one or more bonus award ineligibility time periods of one or more bonus event component sequences are initiated and/or concluded, one or more bonus award eligibility time periods of one or more bonus event component sequences are initiated and/or concluded, and/or one or more players are selected to be provided one or more bonus awards of one or more bonus event component sequences based on an amount of coin-out. In this embodiment, the gaming system determines if an amount of coin-out reaches or exceeds a designated amount of coin-out (i.e., a threshold coin-out amount). Upon the amount of coin-out reaching or exceeding the threshold coin-out amount, the gaming system causes one or more of such events or conditions to occur. In another such embodiment, a bonus event triggering condition is satisfied, one or more bonus award ineligibility time periods of one or more bonus event component sequences are initiated and/or concluded, one or more bonus award eligibility time periods of one or more bonus event component sequences are initiated and/or concluded, and/or one or more players are selected to be provided one or more bonus awards of one or more bonus event component sequences occurs based on an amount of virtual currency-out. In this embodiment, the gaming system determines if an amount of virtual currency-out reaches or exceeds a designated amount of virtual currency-out (i.e., a threshold virtual currency-out amount). Upon the amount of virtual currency-out reaching or exceeding the threshold virtual currency-out amount, the gaming system causes one or more of such events or conditions to occur. In different embodiments, the threshold coin-out amount and/or the threshold virtual currency-out amount is predetermined, randomly determined, determined based on a player&#39;s status (such as determined through a player tracking system), determined based on a generated symbol or symbol combination, determined based on a random determination by the central controller, determined based on a random determination at the gaming device, determined based on one or more side wagers placed, determined based on the player&#39;s primary game wager, determined based on time (such as the time of day) or determined based on any other suitable method or criteria. 
     In different embodiments, a bonus event triggering condition is satisfied, one or more bonus award ineligibility time periods of one or more bonus event component sequences are initiated and/or concluded, one or more bonus award eligibility time periods of one or more bonus event component sequences are initiated and/or concluded, and/or one or more players are selected to be provided one or more bonus awards of one or more bonus event component sequences, based on a predefined variable reaching a defined parameter threshold. For example, when the 500,000 th  player has played an electronic gaming machine of the gaming system (ascertained from a player tracking system), one or more of such events or conditions occur. In different embodiments, the predefined parameter thresholds include a length of time, a length of time after a certain dollar amount is hit, a wager level threshold for a specific device (which electronic gaming machine is the first to contribute $250,000), a number of electronic gaming machines active, or any other parameter that defines a suitable threshold. 
     In different embodiments, a bonus event triggering condition is satisfied, one or more bonus award ineligibility time periods of one or more bonus event component sequences are initiated and/or concluded, one or more bonus award eligibility time periods of one or more bonus event component sequences are initiated and/or concluded, and/or one or more players are selected to be provided one or more bonus awards of one or more bonus event component sequences, based on a quantity of games played. In this embodiment, a quantity of games played is set for when one or more of such events or conditions will occur. In one embodiment, such a set quantity of games played is based on historic data. 
     In different embodiments, a bonus event triggering condition is satisfied, one or more bonus award ineligibility time periods of one or more bonus event component sequences are initiated and/or concluded, one or more bonus award eligibility time periods of one or more bonus event component sequences are initiated and/or concluded, and/or one or more players are selected to be provided one or more bonus awards of one or more bonus event component sequences, based on time. In this embodiment, a time is set for when one or more of such events or conditions will occur. In one embodiment, such a set time is based on historic data. 
     In different embodiments, a bonus event triggering condition is satisfied, one or more bonus award ineligibility time periods of one or more bonus event component sequences are initiated and/or concluded, one or more bonus award eligibility time periods of one or more bonus event component sequences are initiated and/or concluded, and/or one or more players are selected to be provided one or more bonus awards of one or more bonus event component sequences, based upon gaming system operator defined player eligibility parameters stored on a player tracking system (such as via a player tracking card or other suitable manner). In this embodiment, the parameters for eligibility are defined by the gaming system operator based on any suitable criterion. In one embodiment, the gaming system recognizes the player&#39;s identification (via the player tracking system) when the player inserts or otherwise associates their player tracking card in the electronic gaming machine. The gaming system determines the player tracking level of the player and if the current player tracking level defined by the gaming system operator is eligible for one or more of such events or conditions. In one embodiment, the gaming system operator defines minimum bet levels required for such events or conditions to occur based on the player&#39;s card level. 
     In different embodiments, a bonus event triggering condition is satisfied, one or more bonus award ineligibility time periods of one or more bonus event component sequences are initiated and/or concluded, one or more bonus award eligibility time periods of one or more bonus event component sequences are initiated and/or concluded, and/or one or more players are selected to be provided one or more bonus awards of one or more bonus event component sequences, based on a system determination, including one or more random selections by the central controller. In one embodiment, as described above, the gaming system tracks all active electronic gaming machines and the wagers they placed. In one such embodiment, based on the electronic gaming machine&#39;s state as well as one or more wager pools associated with the electronic gaming machine, the gaming system determines whether to one or more of such events or conditions will occur. In one such embodiment, the player who consistently places a higher wager is more likely to be associated with an occurrence of one or more of such events or conditions than a player who consistently places a minimum wager. It should be appreciated that the criteria for determining whether a player is in active status or inactive status for determining if one or more of such events occur may the same as, substantially the same as, or different than the criteria for determining whether a player is in active status or inactive status for another one of such events to occur. 
     In different embodiments, a bonus event triggering condition is satisfied, one or more bonus award ineligibility time periods of one or more bonus event component sequences are initiated and/or concluded, one or more bonus award eligibility time periods of one or more bonus event component sequences are initiated and/or concluded, and/or one or more players are selected to be provided one or more bonus awards of one or more bonus event component sequences, based on a determination of if any numbers allotted to an electronic gaming machine match a randomly selected number. In this embodiment, upon or prior to each play of each electronic gaming machine, an electronic gaming machine selects a random number from a range of numbers and during each primary game, the electronic gaming machine allocates the first N numbers in the range, where N is the number of credits bet by the player in that primary game. At the end of the primary game, the randomly selected number is compared with the numbers allocated to the player and if a match occurs, one or more of such events or conditions occur. It should be appreciated that any suitable manner of causing a bonus event triggering condition to be satisfied, one or more bonus award ineligibility time periods of one or more bonus event component sequences to be initiated and/or concluded, one or more bonus award eligibility time periods of one or more bonus event component sequences to be initiated and/or concluded, and/or one or more players to be selected to be provided one or more bonus awards of one or more bonus event component sequences occur may be implemented in accordance with the gaming system and method disclosed herein. 
     It should be appreciated that one or more of the above-described triggers pertaining to the satisfaction of a bonus event triggering condition, the initiation and/or conclusion of one or more bonus award ineligibility time periods of one or more bonus event component sequences, the initiation or conclusion of one or more bonus award eligibility time periods of one or more bonus event component sequences and/or the selection of one or more players to be provided one or more bonus awards of one or more bonus event component sequences may be combined in one or more different embodiments.

It should be appreciated that one, more, or each of the functions of the central server, central controller, or remote host may be performed by the at least one processor of the EGM. It should be further appreciated that one, more, or each of the functions of the at least one processor of the EGM may be performed by the at least one processor of the central server, central controller, or remote host. 
     In certain such embodiments, computerized instructions for controlling any games (such as any primary or base games and/or any secondary or bonus games) displayed by the EGM are executed by the central server, central controller, or remote host. In such “thin client” embodiments, the central server, central controller, or remote host remotely controls any games (or other suitable interfaces) displayed by the EGM, and the EGM is utilized to display such games (or suitable interfaces) and to receive one or more inputs or commands. In other such embodiments, computerized instructions for controlling any games displayed by the EGM are communicated from the central server, central controller, or remote host to the EGM and are stored in at least one memory device of the EGM. In such “thick client” embodiments, the at least one processor of the EGM executes the computerized instructions to control any games (or other suitable interfaces) displayed by the EGM. 
     In various embodiments in which the gaming system includes a plurality of EGMs, one or more of the EGMs are thin client EGMs and one or more of the EGMs are thick client EGMs. In other embodiments in which the gaming system includes one or more EGMs, certain functions of one or more of the EGMs are implemented in a thin client environment, and certain other functions of one or more of the EGMs are implemented in a thick client environment. In one such embodiment in which the gaming system includes an EGM and a central server, central controller, or remote host, computerized instructions for controlling any primary or base games displayed by the EGM are communicated from the central server, central controller, or remote host to the EGM in a thick client configuration, and computerized instructions for controlling any secondary or bonus games or other functions displayed by the EGM are executed by the central server, central controller, or remote host in a thin client configuration. 
     In certain embodiments in which the gaming system includes: (a) an EGM configured to communicate with a central server, central controller, or remote host through a data network; and/or (b) a plurality of EGMs configured to communicate with one another through a data network, the data network is a local area network (LAN) in which the EGMs are located substantially proximate to one another and/or the central server, central controller, or remote host. In one example, the EGMs and the central server, central controller, or remote host are located in a gaming establishment or a portion of a gaming establishment. 
     In other embodiments in which the gaming system includes: (a) an EGM configured to communicate with a central server, central controller, or remote host through a data network; and/or (b) a plurality of EGMs configured to communicate with one another through a data network, the data network is a wide area network (WAN) in which one or more of the EGMs are not necessarily located substantially proximate to another one of the EGMs and/or the central server, central controller, or remote host. For example, one or more of the EGMs are located: (a) in an area of a gaming establishment different from an area of the gaming establishment in which the central server, central controller, or remote host is located; or (b) in a gaming establishment different from the gaming establishment in which the central server, central controller, or remote host is located. In another example, the central server, central controller, or remote host is not located within a gaming establishment in which the EGMs are located. It should be appreciated that in certain embodiments in which the data network is a WAN, the gaming system includes a central server, central controller, or remote host and an EGM each located in a different gaming establishment in a same geographic area, such as a same city or a same state. It should be appreciated that gaming systems in which the data network is a WAN are substantially identical to gaming systems in which the data network is a LAN, though the quantity of EGMs in such gaming systems may vary relative to one another. 
     In further embodiments in which the gaming system includes: (a) an EGM configured to communicate with a central server, central controller, or remote host through a data network; and/or (b) a plurality of EGMs configured to communicate with one another through a data network, the data network is an internet or an intranet. In certain such embodiments, an internet browser of the EGM is usable to access an internet game page from any location where an internet connection is available. In one such embodiment, after the internet game page is accessed, the central server, central controller, or remote host identifies a player prior to enabling that player to place any wagers on any plays of any wagering games. In one example, the central server, central controller, or remote host identifies the player by requiring a player account of the player to be logged into via an input of a unique username and password combination assigned to the player. It should be appreciated, however, that the central server, central controller, or remote host may identify the player in any other suitable manner, such as by validating a player tracking identification number associated with the player; by reading a player tracking card or other smart card inserted into a card reader (as described below); by validating a unique player identification number associated with the player by the central server, central controller, or remote host; or by identifying the EGM, such as by identifying the MAC address or the IP address of the internet facilitator. In various embodiments, once the central server, central controller, or remote host identifies the player, the central server, central controller, or remote host enables placement of one or more wagers on one or more plays of one or more primary or base games and/or one or more secondary or bonus games, and displays those plays via the internet browser of the EGM. 
     It should be appreciated that the central server, central server, or remote host and the EGM are configured to connect to the data network or remote communications link in any suitable manner.

     Operation of Primary or Base Games and/or Secondary or Bonus Games 
     In various embodiments, an EGM may be implemented in one of a variety of different configurations. In various embodiments, the EGM may be implemented as one of: (a) a dedicated EGM wherein computerized game programs executable by the EGM for controlling any primary or base games (referred to herein as “primary games”) and/or any secondary or bonus games or other functions (referred to herein as “secondary games”) displayed by the EGM are provided with the EGM prior to delivery to a gaming establishment or prior to being provided to a player; and (b) a changeable EGM wherein computerized game programs executable by the EGM for controlling any primary games and/or secondary games displayed by the EGM are downloadable to the EGM through a data network or remote communication link after the EGM is physically located in a gaming establishment or after the EGM is provided to a player. 
     As generally explained above, in various embodiments in which the gaming system includes a central server, central controller, or remote host and a changeable EGM, the at least one memory device of the central server, central controller, or remote host stores different game programs and instructions executable by the at least one processor of the changeable EGM to control one or more primary games and/or secondary games displayed by the changeable EGM. More specifically, each such executable game program represents a different game or a different type of game that the at least one changeable EGM is configured to operate. In one example, certain of the game programs are executable by the changeable EGM to operate games having the same or substantially the same game play but different paytables. In different embodiments, each executable game program is associated with a primary game, a secondary game, or both. In certain embodiments, an executable game program is executable by the at least one processor of the at least one changeable EGM as a secondary game to be played simultaneously with a play of a primary game (which may be downloaded to or otherwise stored on the at least one changeable EGM), or vice versa. 
     In operation of such embodiments, the central server, central controller, or remote host is configured to communicate one or more of the stored executable game programs to the at least one processor of the changeable EGM. In different embodiments, a stored executable game program is communicated or delivered to the at least one processor of the changeable EGM by: (a) embedding the executable game program in a device or a component (such as a microchip to be inserted into the changeable EGM); (b) writing the executable game program onto a disc or other media; or (c) uploading or streaming the executable game program over a data network (such as a dedicated data network). After the executable game program is communicated from the central server, central controller, or remote host to the changeable EGM, the at least one processor of the changeable EGM executes the executable game program to enable the primary game and/or the secondary game associated with that executable game program to be played using the display device(s) and/or the input device(s) of the changeable EGM. That is, when an executable game program is communicated to the at least one processor of the changeable EGM, the at least one processor of the changeable EGM changes the game or the type of game that may be played using the changeable EGM. 
     In certain embodiments, the gaming system randomly determines any game outcome(s) (such as a win outcome) and/or award(s) (such as a quantity of credits to award for the win outcome) for a play of a primary game and/or a play of a secondary game based on probability data. In certain such embodiments, this random determination is provided through utilization of an RNG, such as a true RNG or a pseudo RNG, or any other suitable randomization process. In one such embodiment, each game outcome or award is associated with a probability, and the gaming system generates the game outcome(s) and/or the award(s) to be provided based on the associated probabilities. In these embodiments, since the gaming system generates game outcomes and/or awards randomly or based on one or more probability calculations, there is no certainty that the gaming system will ever provide any specific game outcome and/or award. 
     In certain embodiments, the gaming system maintains one or more predetermined pools or sets of predetermined game outcomes and/or awards. In certain such embodiments, upon generation or receipt of a game outcome and/or award request, the gaming system independently selects one of the predetermined game outcomes and/or awards from the one or more pools or sets. The gaming system flags or marks the selected game outcome and/or award as used. Once a game outcome or an award is flagged as used, it is prevented from further selection from its respective pool or set; that is, the gaming system does not select that game outcome or award upon another game outcome and/or award request. The gaming system provides the selected game outcome and/or award. At least U.S. Pat. Nos. 7,470,183; 7,563,163; and 7,833,092 and U.S. Patent Application Publication Nos. 2005/0148382, 2006/0094509, and 2009/0181743 describe various examples of this type of award determination. 
     In certain embodiments, the gaming system determines a predetermined game outcome and/or award based on the results of a bingo, keno, or lottery game. In certain such embodiments, the gaming system utilizes one or more bingo, keno, or lottery games to determine the predetermined game outcome and/or award provided for a primary game and/or a secondary game. The gaming system is provided or associated with a bingo card. Each bingo card consists of a matrix or array of elements, wherein each element is designated with separate indicia. After a bingo card is provided, the gaming system randomly selects or draws a plurality of the elements. As each element is selected, a determination is made as to whether the selected element is present on the bingo card. If the selected element is present on the bingo card, that selected element on the provided bingo card is marked or flagged. This process of selecting elements and marking any selected elements on the provided bingo cards continues until one or more predetermined patterns are marked on one or more of the provided bingo cards. After one or more predetermined patterns are marked on one or more of the provided bingo cards, game outcome and/or award is determined based, at least in part, on the selected elements on the provided bingo cards. At least U.S. Pat. Nos. 7,753,774; 7,731,581; 7,955,170; and 8,070,579 and U.S. Patent Application Publication No. 2011/0028201 describe various examples of this type of award determination. 
     In certain embodiments in which the gaming system includes a central server, central controller, or remote host and an EGM, the EGM is configured to communicate with the central server, central controller, or remote host for monitoring purposes only. In such embodiments, the EGM determines the game outcome(s) and/or award(s) to be provided in any of the manners described above, and the central server, central controller, or remote host monitors the activities and events occurring on the EGM. In one such embodiment, the gaming system includes a real-time or online accounting and gaming information system configured to communicate with the central server, central controller, or remote host. In this embodiment, the accounting and gaming information system includes: (a) a player database for storing player profiles, (b) a player tracking module for tracking players (as described below), and (c) a credit system for providing automated transactions. At least U.S. Pat. No. 6,913,534 and U.S. Patent Application Publication No. 2006/0281541 describe various examples of such accounting systems. 
     As noted above, in various embodiments, the gaming system includes one or more executable game programs executable by at least one processor of the gaming system to provide one or more primary games and one or more secondary games. The primary game(s) and the secondary game(s) may comprise any suitable games and/or wagering games, such as, but not limited to: electro-mechanical or video slot or spinning reel type games; video card games such as video draw poker, multi-hand video draw poker, other video poker games, video blackjack games, and video baccarat games; video keno games; video bingo games; and video selection games. 
     In certain embodiments in which the primary game is a slot or spinning reel type game, the gaming system includes one or more reels in either an electromechanical form with mechanical rotating reels or in a video form with simulated reels and movement thereof. Each reel displays a plurality of indicia or symbols, such as bells, hearts, fruits, numbers, letters, bars, or other images that typically correspond to a theme associated with the gaming system. In certain such embodiments, the gaming system includes one or more paylines associated with the reels. The example EGMs shown in  FIGS. 5A and 5B  each include a payline  1152  and a plurality of reels  1154 . In certain embodiments, one or more of the reels are independent reels or unisymbol reels. In such embodiments, each independent reel generates and displays one symbol. 
     In various embodiments, one or more of the paylines is horizontal, vertical, circular, diagonal, angled, or any suitable combination thereof. In other embodiments, each of one or more of the paylines is associated with a plurality of adjacent symbol display positions on a requisite number of adjacent reels. In one such embodiment, one or more paylines are formed between at least two symbol display positions that are adjacent to each other by either sharing a common side or sharing a common corner (i.e., such paylines are connected paylines). The gaming system enables a wager to be placed on one or more of such paylines to activate such paylines. In other embodiments in which one or more paylines are formed between at least two adjacent symbol display positions, the gaming system enables a wager to be placed on a plurality of symbol display positions, which activates those symbol display positions. 
     In various embodiments, the gaming system provides one or more awards after a spin of the reels when specified types and/or configurations of the indicia or symbols on the reels occur on an active payline or otherwise occur in a winning pattern, occur on the requisite number of adjacent reels, and/or occur in a scatter pay arrangement. 
     In certain embodiments, the gaming system employs a ways to win award determination. In these embodiments, any outcome to be provided is determined based on a number of associated symbols that are generated in active symbol display positions on the requisite number of adjacent reels (i.e., not on paylines passing through any displayed winning symbol combinations). If a winning symbol combination is generated on the reels, one award for that occurrence of the generated winning symbol combination is provided. At least U.S. Pat. No. 8,012,011 and U.S. Patent Application Publication Nos. 2008/0108408 and 2008/0132320 describe various examples of ways to win award determinations. 
     In various embodiments, the gaming system includes a progressive award. Typically, a progressive award includes an initial amount and an additional amount funded through a portion of each wager placed to initiate a play of a primary game. When one or more triggering events occurs, the gaming system provides at least a portion of the progressive award. After the gaming system provides the progressive award, an amount of the progressive award is reset to the initial amount and a portion of each subsequent wager is allocated to the next progressive award. At least U.S. Pat. Nos. 5,766,079; 7,585,223; 7,651,392; 7,666,093; 7,780,523; and 7,905,778 and U.S. Patent Application Publication Nos. 2008/0020846, 2009/0123364, 2009/0123363, and 2010/0227677 describe various examples of different progressive gaming systems. 
     As generally noted above, in addition to providing winning credits or other awards for one or more plays of the primary game(s), in various embodiments the gaming system provides credits or other awards for one or more plays of one or more secondary games. The secondary game typically enables an award to be obtained addition to any award obtained through play of the primary game(s). The secondary game(s) typically produces a higher level of player excitement than the primary game(s) because the secondary game(s) provides a greater expectation of winning than the primary game(s) and is accompanied with more attractive or unusual features than the primary game(s). It should be appreciated that the secondary game(s) may be any type of suitable game, either similar to or completely different from the primary game. 
     In various embodiments, the gaming system automatically provides or initiates the secondary game upon the occurrence of a triggering event or the satisfaction of a qualifying condition. In other embodiments, the gaming system initiates the secondary game upon the occurrence of the triggering event or the satisfaction of the qualifying condition and upon receipt of an initiation input. In certain embodiments, the triggering event or qualifying condition is a selected outcome in the primary game(s) or a particular arrangement of one or more indicia on a display device for a play of the primary game(s), such as a “BONUS” symbol appearing on three adjacent reels along a payline following a spin of the reels for a play of the primary game. In other embodiments, the triggering event or qualifying condition occurs based on a certain amount of game play (such as number of games, number of credits, amount of time) being exceeded, or based on a specified number of points being earned during game play. It should be appreciated that any suitable triggering event or qualifying condition or any suitable combination of a plurality of different triggering events or qualifying conditions may be employed. 
     In other embodiments, at least one processor of the gaming system randomly determines when to provide one or more plays of one or more secondary games. In one such embodiment, no apparent reason is provided for the providing of the secondary game. In this embodiment, qualifying for a secondary game is not triggered by the occurrence of an event in any primary game or based specifically on any of the plays of any primary game. That is, qualification is provided without any explanation or, alternatively, with a simple explanation. In another such embodiment, the gaming system determines qualification for a secondary game at least partially based on a game triggered or symbol triggered event, such as at least partially based on play of a primary game. 
     In various embodiments, after qualification for a secondary game has been determined, the secondary game participation may be enhanced through continued play on the primary game. Thus, in certain embodiments, for each secondary game qualifying event, such as a secondary game symbol, that is obtained, a given number of secondary game wagering points or credits is accumulated in a “secondary game meter” configured to accrue the secondary game wagering credits or entries toward eventual participation in the secondary game. In one such embodiment, the occurrence of multiple such secondary game qualifying events in the primary game results in an arithmetic or exponential increase in the number of secondary game wagering credits awarded. In another such embodiment, any extra secondary game wagering credits may be redeemed during the secondary game to extend play of the secondary game. 
     In certain embodiments, no separate entry fee or buy-in for the secondary game is required. That is, entry into the secondary game cannot be purchased; rather, in these embodiments entry must be won or earned through play of the primary game, thereby encouraging play of the primary game. In other embodiments, qualification for the secondary game is accomplished through a simple “buy-in.” For example, qualification through other specified activities is unsuccessful, payment of a fee or placement of an additional wager “buys-in” to the secondary game. In certain embodiments, a separate side wager must be placed on the secondary game or a wager of a designated amount must be placed on the primary game to enable qualification for the secondary game. In these embodiments, the secondary game triggering event must occur and the side wager (or designated primary game wager amount) must have been placed for the secondary game to trigger. 
     In various embodiments in which the gaming system includes a plurality of EGMs, the EGMs are configured to communicate with one another to provide a group gaming environment. In certain such embodiments, the EGMs enable players of those EGMs to work in conjunction with one another, such as by enabling the players to play together as a team or group, to win one or more awards. In other such embodiments, the EGMs enable players of those EGMs to compete against one another for one or more awards. In one such embodiment, the EGMs enable the players of those EGMs to participate in one or more gaming tournaments for one or more awards. At least U.S. Patent Application Publication Nos. 2007/0123341, 2008/0070680, 2008/0176650, and 2009/0124363 describe various examples of different group gaming systems. 
     In various embodiments, the gaming system includes one or more player tracking systems. Such player tracking systems enable operators of the gaming system (such as casinos or other gaming establishments) to recognize the value of customer loyalty by identifying frequent customers and rewarding them for their patronage. Such a player tracking system is configured to track a player&#39;s gaming activity. In one such embodiment, the player tracking system does so through the use of player tracking cards. In this embodiment, a player is issued a player identification card that has an encoded player identification number that uniquely identifies the player. When the player&#39;s playing tracking card is inserted into a card reader of the gaming system to begin a gaming session, the card reader reads the player identification number off the player tracking card to identify the player. The gaming system timely tracks any suitable information or data relating to the identified player&#39;s gaming session. The gaming system also timely tracks when the player tracking card is removed to conclude play for that gaming session. In another embodiment, rather than requiring insertion of a player tracking card into the card reader, the gaming system utilizes one or more portable devices, such as a cell phone, a radio frequency identification tag, or any other suitable wireless device, to track when a gaming session begins and ends. In another embodiment, the gaming system utilizes any suitable biometric technology or ticket technology to track when a gaming session begins and ends. 
     In such embodiments, during one or more gaming sessions, the gaming system tracks any suitable information or data, such as any amounts wagered, average wager amounts, and/or the time at which these wagers are placed. In different embodiments, for one or more players, the player tracking system includes the player&#39;s account number, the player&#39;s card number, the player&#39;s first name, the player&#39;s surname, the player&#39;s preferred name, the player&#39;s player tracking ranking, any promotion status associated with the player&#39;s player tracking card, the player&#39;s address, the player&#39;s birthday, the player&#39;s anniversary, the player&#39;s recent gaming sessions, or any other suitable data. In various embodiments, such tracked information and/or any suitable feature associated with the player tracking system is displayed on a player tracking display. In various embodiments, such tracked information and/or any suitable feature associated with the player tracking system is displayed via one or more service windows that are displayed on the central display device and/or the upper display device. At least U.S. Pat. Nos. 6,722,985; 6,908,387; 7,311,605; 7,611,411; 7,617,151; and 8,057,298 describe various examples of player tracking systems.
