BACKGROUND
To play a conventional slot machine, a player deposits money in the form of coins, gaming tokens, paper currency or tickets either into a coin slot or bill acceptor, respectively. The coins and gaming tokens are collected in a reservoir inside the gaming machine while the paper currency or ticket is collected in the bill acceptor inside the gaming machine. If the coins, gaming tokens, paper currency or ticket are validated as authentic, the player accrues the appropriate number of playing credits on a credit meter. For example, a twenty-five cent gaming machine will accrue four credits for each dollar deposited into the gaming machine.
After accruing credits on the credit meter, the player determines how many credits to wager on the next spin of the slot reels. The player causes the gaming device to spin the reels by pressing the spin button or by pulling a handle. When the reels stop spinning, symbols are displayed on the reels at symbol positions. Outcomes or awards, if any, are provided to a player based on designated symbol combinations indicated in a paytable or award summary table.
More specifically, many conventional slot machines include a symbol matrix which includes symbols displayed on three or more of the reels (also called “columns” or “reel columns”) that are adjacent to each other. The resulting matrix of symbols typically ranges from three columns by three rows with nine total symbols, to five columns by three rows with fifteen total symbols. Each position in the symbol matrix is referenced by column, from left to right, and row, from the top to bottom (“symbol positions”). For example: symbol position 1/2 is located in column 1 and row 2. Players collect credits for predetermined winning symbol combinations on the reels that appear in specific or designated symbol positions. The combination of these designated symbol positions are generally referred to as “paylines.”
Conventional gaming devices employ different symbols to form different winning symbol combinations in a game. Conventional gaming devices also employ different symbols which perform a function in a game. One such symbol is a wild symbol or wild card. Wild symbols provide a player with an additional opportunity to obtain winning combinations. Wild symbols, wild cards and wild indicators in gaming devices also provide additional excitement and entertainment for players.
In a slot machine having reels, a wild symbol can enable the matching of symbols along a payline to achieve a combination. For example, in a three reel slot machine, the symbols along a payline on the first, second and third reels may be, respectively, a heart, a heart and a wild symbol. If, in the gaming scheme, the gaming device awards a player for a three heart combination, the wild symbol substitutes for or functions as a heart and provides the player with that combination.
Known slot machine games include wild symbols placed on the reel strips, with each wild symbol substituting for all line pay symbols.
Known slot machine games include wild symbols placed on the reel strips, with each wild symbol substituting for some line pay symbols.
Known slot machine games include wild symbols placed on the reel strips, with each wild symbol expanding to all positions on the slot reel and substituting for all line pay symbols.
U.S. Pat. No. 6,089,977 discloses a slot machine game including wild symbols placed on the reel strips, where a wild symbol substitutes for all symbols and, upon a trigger event, moves to each position in the symbol matrix.
U.S. Pat. No. 6,517,432 discloses a slot machine game including wild symbols placed on the reel strips, where each wild symbol substitutes for all symbols and, upon a trigger event, moves to a random number of positions in the symbol matrix.
These conventional slot machines generate wild symbols based on fixed rules where all of the symbols are generated and displayed in a symbol matrix by the slot machine. These slot machines do not provide a random generation of wild symbols based on one or more decisions by a player.
There is a need for new gaming devices including new gaming machines which increase a player's chances for obtaining winning symbol combinations in a game.
SUMMARY
One embodiment of the present invention is directed to a gaming device (and method of operating a gaming device) including a plurality of symbol generators such as reels which generate a plurality of player selectable symbols in a game (such as a bonus game) which each reveal a value or a wild symbol when a player picks the selectable symbols in a play of the game. The player's decision to pick each selectable symbol in the game affects the number and/or location of wild symbols in the game. For example, the player's decisions may cause the second, third and fourth reels of a set of five reels to display wild symbols and thereby enhance the player's chances of obtaining a winning outcome such as an award in the game.
In one embodiment, the game is triggered by a triggering event such as an occurrence of one or more designated trigger symbols appearing any where on reels two, three and four in a primary or base game. After the triggering event occurs in the primary or base game, the gaming device initiates a bonus game and causes a plurality or all of the displayed symbols on reels two, three and four to be replaced with or changed to bonus game symbols or selectable symbols.
In the bonus game, the gaming device enables the player to select or pick one of the selectable symbols on reel two. The selected symbol transforms and reveals either a value symbol or a wild symbol. The selection of a value symbol provides the player with an outcome such as a value or an award equal to an amount associated with the value symbol. The bonus game ends and the gaming device provides the value or award to the player in the bonus game. If the picked selectable symbols reveals a wild symbol, the gaming device replaces or changes one, a plurality or all of the displayed symbols on that reel into wild symbols and the bonus game continues.
If the game continues, the gaming device enables the player to select or pick one of the selectable symbols on reel three. If the picked selectable symbol reveals a value symbol, the gaming device provides the award associated with the value symbol to the player and the bonus game ends. If the picked selectable symbol is a wild symbol, the gaming device replaces or changes one, a plurality or all of the displayed symbols on that reel into wild symbols and the bonus game continues. The gaming device now displays two reels with wild symbols in the bonus game.
If the bonus game continues, the gaming device enables the player to select or pick one of the selectable symbols on reel four. If the picked selectable symbol reveals a value symbol, the gaming device provides the award associated with the value symbol to the player and the bonus game ends. If the picked selectable symbol is a wild symbol, the gaming device replaces or changes one, a plurality or all of the displayed symbols on that reel into wild symbols. The gaming device then evaluates the symbols on the reels including the wild symbols which are indicated by the activated or wagered on paylines to determine if any winning symbol combinations are indicated by the activated paylines. The gaming device provides any outcomes or awards associated with winning symbol combinations indicated by the activated paylines associated with the reels. The gaming device also provides any values or awards associated with revealed value symbols to the player in the bonus game.
In alternative embodiments, the gaming device re-spins one, a plurality or all of the reels which do not include the wild symbols to form new symbol combinations in a play of the game. In these embodiments, the gaming device evaluates the symbol combinations indicated by the activated or wagered on paylines after re-spinning the reels. The gaming device then provides the player with any outcomes or awards associated with the symbol combinations indicated by the activated paylines.
As described above, the selectable symbols including the value symbols and the wild symbols provide new winning symbol combinations in the bonus game and thereby enhance a player's chances of obtaining several awards in the bonus game and potentially a very large award in the bonus game.
It is therefore an advantage of the present invention to provide a gaming device having a player selectable symbols that reveal one or more wild symbols or values in a game.
Additional features and advantages of the present invention are described in, and will be apparent from, the following Detailed Description of the Invention and the figures.

In this embodiment, the gaming device awards prizes when the reels of the primary game stop spinning if specified types and/or configurations of indicia or symbols occur on an active pay line or otherwise occur in a winning pattern.
In one embodiment, in addition to winning credits in a base or primary game, the gaming device may also give players the opportunity to win credits in a bonus or secondary game or bonus or secondary round. The bonus or secondary game enables the player to obtain a prize or payout in addition to the prize or payout, if any, obtained from the base or primary game. In general, a bonus or secondary game produces a significantly higher level of player excitement than the base or primary game because it provides a greater expectation of winning than the base or primary game and is accompanied with more attractive or unusual features than the base or primary game.
In one embodiment, the bonus or secondary game may be any type of suitable game, either similar to or completely different from the base or primary game. In one embodiment, the gaming device includes a program which will automatically begin a bonus round when the player has achieved a triggering event or qualifying condition in the base or primary game. In one embodiment, the triggering event or qualifying condition may be a selected outcome in the primary game or a particular arrangement of one or more indicia on a display device in the primary game, such as the number seven appearing on three adjacent reels along a payline in the primary slot game embodiment seen in FIGS. 1A and 1B. In another embodiment, the triggering event or qualifying condition may be by exceeding a certain amount of game play (number of games, number of credits, amount of time), reaching a specified number of points earned during game play or as a random award.
In one embodiment, once a player has qualified for a bonus game, the player may subsequently enhance his/her bonus game participation through continued play on the base or primary game. Thus, for each bonus qualifying event, such as a bonus symbol, that the player obtains, a given number of bonus game wagering points or credits may be accumulated in a “bonus meter” programmed to accrue the bonus wagering credits or entries toward eventual participation in a bonus game. The occurrence of multiple such bonus qualifying events in the primary game may result in an arithmetic or geometric increase in the number of bonus wagering credits awarded. In one embodiment, extra bonus wagering credits may be redeemed during the bonus game to extend play of the bonus game.
In one embodiment, no separate entry fee or buy in for a bonus game need be employed. That is, a player may not purchase an entry into a bonus game; the must win or earn entry through play of the primary game and, thus, play of the primary game is encouraged. In another embodiment, qualification of the bonus or secondary game could be accomplished through a simple “buy in” by the player if, for example, the player has been unsuccessful at qualifying through other specified activities.
In one embodiment, as illustrated in FIG. 2B, one or more of the gaming devices 10 of the present invention may be connected to each other through a data network or a remote communication link 58 with some or all of the functions of each gaming device provided at a central location such as a central server or central controller 56. More specifically, the processor of each gaming device may be designed to facilitate transmission of signals between the individual gaming device and the central server or controller.
In one embodiment, the game outcome provided to the player is determined by a central server or controller and provided to the player at the gaming device of the present invention. In this embodiment, each of a plurality of such gaming devices are in communication with the central server or controller. Upon a player initiating game play at one of the gaming devices, the initiated gaming device communicates a game outcome request to the central server or controller.
In one embodiment, the central server or controller receives the game outcome request and randomly generates a game outcome for the primary game based on probability data. In another embodiment, the central server or controller randomly generates a game outcome for the secondary game based on probability data. In another embodiment, the central server or controller randomly generates a game outcome for both the primary game and the secondary game based on probability data. In this embodiment, the central server or controller is capable of storing and utilizing program code or other data similar to the processor and memory device of the gaming device.
In an alternative embodiment, the central server or controller maintains one or more predetermined pools or sets of predetermined game outcomes. In this embodiment, the central server or controller receives the game outcome request and independently selects a predetermined game outcome from a set or pool of game outcomes. The central server or controller flags or marks the selected game outcome as used. Once a game outcome is flagged as used, it is prevented from further selection from the set or pool and cannot be selected by the central controller or server upon another wager. The provided game outcome can include a primary game outcome, a secondary game outcome, primary and secondary game outcomes, or a series of game outcomes such a free games.
The central server or controller communicates the generated or selected game outcome to the initiated gaming device. The gaming device receives the generated or selected game outcome and provides the game outcome to the player. In an alternative embodiment, how the generated or selected game outcome is to be presented or displayed to the player, such as a reel symbol combination of a slot machine or a hand of cards dealt in a card game, is also determined by the central server or controller and communicated to the initiated gaming device to be presented or displayed to the player. Central production or control can assist a gaming establishment or other entity in maintaining appropriate records, controlling gaming, reducing and preventing cheating or electronic or other errors, reducing or eliminating win-loss volatility and the like.
In another embodiment, one or more of the gaming devices of the present invention are in communication with a central server or controller for monitoring purposes only. That is, each individual gaming device randomly generates the game outcomes to be provided to the player and the central server or controller monitors the activities and events occurring on the plurality of gaming devices. In one embodiment, the gaming network includes a real-time or on-line accounting and gaming information system operably coupled to the central server or controller. The accounting and gaming information system of this embodiment includes a player database for storing player profiles, a player tracking module for tracking players and a credit system for providing automated casino transactions.
A plurality of the gaming devices of the present invention are capable of being connected together through a data network. In one embodiment, the data network is a local area network (LAN), in which one or more of the gaming devices are substantially proximate to each other and an on-site central server or controller as in, for example, a gaming establishment or a portion of a gaming establishment. In another embodiment, the data network is a wide area network (WAN) in which one or more of the gaming devices are in communication with at least one off-site central server or controller. In this embodiment, the plurality of gaming devices may be located in a different part of the gaming establishment or within a different gaming establishment than the off-site central server or controller. Thus, the WAN may include an off-site central server or controller and an off-site gaming device located within gaming establishments in the same geographic area, such as a city or state. The WAN gaming system of the present invention may be substantially identical to the LAN gaming system described above, although the number of gaming devices in each system may vary relative to each other.
In another embodiment, the data network is an internet or intranet. In this embodiment, the operation of the gaming device can be viewed at the gaming device with at least one internet browser. In this embodiment, operation of the gaming device and accumulation of credits may be accomplished with only a connection to the central server or controller (the internet/intranet server) through a conventional phone or other data transmission line, digital signal line (DSL), T-1 line, coaxial cable, fiber optic cable, or other suitable connection. In this embodiment, players may access an Internet game page from any location where an internet connection and computer, or other internet facilitator are available. The expansion in the number of computers and number and speed of internet connections in recent years increases opportunities for players to play from an ever-increasing number of remote sites. It should be appreciated that enhanced bandwidth of digital wireless communications may render such technology suitable for some or all communications according to the present invention, particularly if such communications are encrypted. Higher data transmission speeds may be useful for enhancing the sophistication and response of the display and interaction with the player.
In another embodiment, a plurality of gaming devices at one or more gaming sites may be networked to a central server in a progressive configuration, as known in the art, wherein a portion of each wager to initiate a base or primary game may be allocated to bonus or secondary event awards. In one embodiment, a host site computer is coupled to a plurality of the central servers at a variety of mutually remote gaming sites for providing a multi-site linked progressive automated gaming system. In one embodiment, a host site computer may serve gaming devices distributed throughout a number of properties at different geographical locations including, for example, different locations within a city or different cities within a state.
In one embodiment, the host site computer is maintained for the overall operation and control of the system. In this embodiment, a host site computer oversees the entire progressive gaming system and is the master for computing all progressive jackpots. All participating gaming sites report to, and receive information from, the host site computer. Each central server computer is responsible for all data communication between the gaming device hardware and software and the host site computer.
Player Selectable Wild Symbols
One embodiment of the present invention is directed to a gaming device that enables a player to pick or select one or more selectable symbols in a game after a triggering event occurs in a primary game to reveal a value symbol or a wild symbol. The wild symbol increases a player's chances of obtaining a winning symbol combination in a game and potentially a larger outcome or award in the game. The value symbol provides an outcome such as an award to the player and in one embodiment, ends the game.\
Referring now to FIGS. 3A to 3K, an example of one embodiment of a gaming device of the present invention is illustrated where the gaming device includes a symbol matrix including a plurality of symbol generators such as reels 54a, 54b, 54c, 54d and 54e. Each symbol generator or reel 54 includes a plurality of symbols 100 thereon. The symbols include at least one designated symbol such as trigger symbols 102a, 102b and 102c on reels 54b, 54c and 54d, respectively. It should be appreciated that one, a plurality or all of the reels may include one or a plurality of the trigger symbols in a game. In the illustrated example, the trigger symbols are in the shape of a star. It should be appreciated that the trigger symbol may be any suitable size, shape, symbol, character or image.
A plurality of paylines 52a, 52b and 52c are associated with the reels. Each payline includes one symbol position from each of the five reels 54a, 54b, 54c, 54d and 54e. For the purposes of this application, symbol positions are identified by column, from left to right, and by row, from top to bottom. For example, symbol position 1/1 is located in the leftmost column, topmost row. It should be appreciated that additional paylines may be associated with the reels. It should also be appreciated that any of the paylines may include one or more of the same symbol positions. In this embodiment, payline one or payline 52a includes symbol positions: 1/2, 2/2, 3/2, 4/2, 5/2. Payline two or payline 52b includes symbol positions: 1/1, 2/1, 3/1, 4/1, 5/1. Payline three or payline 52c includes 1/3, 2/3, 3/3, 4/3, 5/3. Alternatively, the game may define any suitable number of paylines including any suitable number of symbol positions, paylines using any location of symbol positions, and/or any order of payline activation.
As illustrated in FIG. 3A, the gaming device also includes a plurality of meters or displays to provide or indicate information to a player in a game such as a number of paylines display 104, a bet per payline display 106, a total bet display 108, a paid display 110 and a credit display 112. The number of paylines display 104 indicates the number of paylines wagered on by a player in a play of the game. The bet per payline display indicates the wager made by the player on each of the paylines. The total bet display 108 indicates the total bet made by the player in the play of the game. The total bet equals the number of paylines wagered on in the play of the game as indicated by the number of paylines display 104 multiplied by the bet per payline indicated by the bet per payline display 106. The paid display 110 indicates the outcome or award paid to the player in that play of the game. The credit display 112 indicates the total accumulated number of credits for the player. It should be appreciated that any suitable meters or displays may be provided in a game.
In this embodiment, the primary or base game provides outcomes or awards for line pay symbol combinations. It should be appreciated that the gaming device may provide an outcome or award for any suitable symbol combination including line pay symbol combinations, scatter pay combinations or any other suitable symbol combination. A line pay combination provides an outcome or award for symbol combinations including the same symbols appearing adjacent on a single payline such as starting from the leftmost position on the payline. Symbols that combine to form line pays may be called line pay symbols. For example, four “A” line pay symbols (i.e. A-A-A-A-C) on a selected payline provides an award to the player but the symbol combination of A-A-B-A-A does not. Reel scatter pays provide outcomes or awards for any combination of the same symbols appearing anywhere on the reels. Symbols that combine to form scatter pays are called scatter pay symbols. For example, any three C symbols anywhere on the reels provides an award to the player in a play of the game.
The gaming device provides awards to a player based on a pay schedule or paytable such as paytable 113 illustrated in FIG. 3B. In FIG. 3B, the paytable 113 includes a column 114 having a plurality of symbol combinations and a column 116 which indicates the outcomes or awards associated with each of the symbol combinations. The gaming device provides the award in column 116 to the player for each occurrence of the corresponding symbol combination on the reels in a play of a game. Although the paytable 113 illustrates fixed outcomes, payouts or awards, it should be appreciated that any suitable outcome may be provided to the player.
It should be appreciated that the pay schedules or pay tables may provide outcomes or awards for any suitable number of the same or different symbols, with such symbols appearing in any order and/or in any location on a payline or on the symbol matrix or reels. Furthermore, the pay table may provide any suitable type or amount of award, including: credits, such as a fixed number of credits or a range of credits, or random amount of credits; a bonus feature, such as a multiplicative factor for credits won; one or more free spins of the reels, with or without an enhanced pay schedule; cash, products, services; any other award of value; and/or any combination of awards; free games, a modifier or any other suitable outcomes or awards.
Referring to FIG. 3A, the gaming device provides a primary or base game including a plurality of reels such as reels 54a, 54b, 54c, 54d and 54e as described above. When a triggering event occurs in the primary game, the gaming device initiates a secondary or bonus game. The triggering event may be a designated number of symbols appearing on the reels or any other suitable triggering event. In FIG. 3A, the triggering event includes three trigger symbols appearing or occurring on the reels in a play of the game. Specifically, three trigger symbols 102a, 102b and 102c occurred on reels 54b, 54c and 54d, respectively. Therefore, the triggering event initiates or activates the secondary or bonus game in this play of the game. Also as shown in FIG. 3A, the player placed a wager to activate three paylines in the play of the game as indicated by the number of paylines display 104. The player also made a wager or bet five credits on each payline as indicated by the bet per payline display 106. Thus, the player's total bet in this play of the game is fifteen as indicated by the total bet display 108. The player has not received any outcomes or awards in the game as indicated by the paid display 110. The player's total bet or wager of fifteen is subtracted from the player's total number of credits or bet in the game of five-hundred to give the player a new total number of credits of four-hundred eighty-five as indicated by the credit meter or credit display 112.
In the secondary or bonus game, the gaming device generates wild symbols based upon one or more player decisions in the game. As illustrated in FIG. 3C, after the triggering event occurs, the gaming device replaces or transforms each of the symbols shown on the reels including the trigger symbols 102a, 102b and 102c with selectable symbols or wild guess symbols 103a, 103b, 103c, 103d, 103e, 103f, 103g, 103h and 103i. The gaming device enables the player to select or pick at least one of the selectable symbols 103 on each of the reels including the selectable symbols in the bonus game. In the illustrated example, the gaming device enables the player to sequentially pick one of the selectable symbols on each of the reels 54a, 54b and 54c until a termination event. It should be appreciated that the gaming device may enable the player to pick one, a plurality or all of the selectable symbols on the reels including the selectable symbols, a designated number of the selectable symbols on the reels, certain of the selectable symbols on the reels or any suitable number of the selectable symbols.
In the illustrated example, the gaming device waits for the player's decision on which of the selectable symbols the player will pick on reel 54b in the bonus game. In this embodiment, if the player does not make a decision within a designated period of time such as a few seconds, the gaming device displays an indicator such as a message “Pick A Symbol” on the same or a separate display and/or play a “Pick A Symbol” audio recording to prompt the player's decision. It should be appreciated that the gaming device may indicate or otherwise prompt the player to make a decision in the game using any suitable prompt, signal, message or indicator.
With each decision, the player may select one of the selectable symbols and reveal either a credit value symbol or a wild symbol. As a result, the player's decisions can lead to four possible scenarios. In scenario #1, the player's symbol selection on reel two reveals a credit value symbol or value. The gaming device evaluates the symbol combinations indicated by the reels and provides any additional awards to the player based on the indicated symbol combinations. The gaming device provides the value and/or the awards to the player and the bonus game ends.
In scenario #2, the player selects a selectable symbol on reel two which reveals a wild symbol followed by the selection of a selectable symbol on reel three which reveals a value symbol. The gaming device evaluates the symbol combinations indicated by the reels and provides any additional awards to the player based on the indicated symbol combinations. The gaming device provides the value and/or the awards to the player and the bonus game ends.
In scenario #3, the player selects a selectable symbol which reveals a wild symbol on reel two, followed by the selection of a selectable symbol on reel three which reveals a wild symbol, followed by a selectable symbol on reel four which reveals a credit value or value symbol. The gaming device evaluates the symbol combinations indicated by the reels and provides any additional awards to the player based on the indicated symbol combinations. The gaming device then provides the value and/or the awards to the player and the bonus game ends.
In scenario #4, the player selects a selectable symbol on reel two which reveals a wild symbol, selects a selectable symbol on reel three which reveals a wild symbol and selects a selectable symbol on reel four which also reveals a wild symbol. The gaming device evaluates the symbol combinations indicated by the reels and provides any additional awards to the player based on the indicated symbol combinations. The gaming device then provides the value and/or the awards to the player and the bonus game ends.
In one embodiment, by including one wild symbol and two value symbols on each reel, the probability of each scenario is: 2/3 (66.67%) for scenario #1, 2/9 (22.22%) for scenario #2, 2/27 (7.41%) for scenario #3 and 1/27 (3.70%) for scenario #4. Under any of the above scenarios, however, the gaming device provides at least one value to the player in the bonus game.
As described above, in scenarios #1 and 2, the player will receive a minimum award including the credits shown or indicated by the credit value symbol or value symbol. In scenario #3, the player receives a minimum award of credits based on the credit value symbol and three symbol line pays on paylines 52a, 52b and 52c. In scenario #4, the player receives awards for five symbol line pays on all of the paylines.
The following example illustrated in FIGS. 3A to 3K depicts scenario #3, with a probability of 2/27 (7.41%), in which the player selects a plurality of selectable symbols which reveals wild symbols on reels 54b and 54c, and then selects a selectable symbol on reel 54d which reveals a value symbol. As illustrated in FIG. 3C, the player selects selectable symbol 103b located in the middle symbol position or symbol position 2/2 of reel 54b. The selected symbol reveals wild symbol 102d as illustrated in FIG. 3D.
Referring now to FIG. 3E, in the illustrated example, the gaming device converts, transforms or changes all of the symbols displayed by reel 54b into wild symbols 113a, 113b and 113c. It should be appreciated that the gaming device may convert or change one, a plurality or all of the symbols to wild symbols. It should also be appreciated that the transformation or conversion of the symbols may be accompanied by sounds and visual effects to highlight the event to the player. The gaming device then enables the player to select or pick one of the selectable symbols 103d, 103e or 103f on reel three or reel 54c in the bonus game.
Referring now to FIGS. 3F and 3G, the player selects or picks the selectable symbol or wild guess symbol in the top symbol position of reel 54c (i.e., symbol position 3/1) as shown in FIG. 3F. The picked selectable symbol reveals a wild symbol as illustrated in FIG. 3G. The second revealed wild symbol now enables the player to obtain three winning symbol combinations on the reels including three of the same symbols in the bonus game.
Referring now to FIG. 3H, the gaming device transforms or changes all of the displayed symbols on reel 54c to wild symbols 118d, 118e and 118f. Because the player did not pick a selectable symbol that revealed a credit value symbol, the gaming device enables the player to pick one of the selectable symbols 103g, 103h or 103i on reel 54d in the bonus game.
Referring now to FIG. 3I, the player selects or picks selectable symbol or wild guess symbol 113i in symbol position 4/3 on reel 54d in the bonus game. As illustrated in FIG. 3J, the selected symbol reveals another wild symbol 118i in the bonus game.
Referring now to FIG. 3K, the gaming device transforms or changes each of the displayed symbols on reel 54d to wild symbols 118g, 118h and 118i. All of the symbol positions of reels 54b, 54c and 54d now display wild symbols. The gaming device evaluates the symbol combinations indicated by each of the activated paylines 52a, 52b and 52c in the bonus game. The gaming device then provides the awards associated with any winning symbol combinations indicated by the activated or wagered on paylines 52a, 52b and 52c in the bonus game. Payline 52a indicates a symbol combination including the symbol A and three wild symbols 118b, 118e and 118h. As illustrated by the paytable FIG. 3B, a symbol combination including four A symbols (i.e., the displayed A symbol and three more A symbols substituted by the wild symbols) provides an award of eighty credits. Payline 52b indicates a winning symbol combination of four G symbols, which provides an award of thirty credits. Payline 52c indicates a winning symbol combination including four B symbols which provides an award of seventy-five credits. In this embodiment, the award for each play of the game equals the total bet multiplied by the award in the bonus game. Therefore, the award for the bonus game equals fifteen as indicated by the total bet display 110 multiplied by one hundred eighty-five which is the total award accumulated by the player in the bonus game. The total award for the bonus game is two thousand seven hundred seventy-five as indicated by the paid display 110. The total award or bonus game award is added to the player's total award to provide a new total award of three thousand two hundred sixty as indicated by the credit display 112.
This example illustrates how the selectable symbols or wild guess symbols in the bonus game increase a player's excitement and enjoyment with the game because the player may obtain several additional awards or possibly a relatively large award in the game. The player also can interact with the game by selecting and determining a portion of the symbol combinations and/or awards in the game which also increases the player's excitement and enjoyment with the game.
Referring now to FIG. 4, another example of the above embodiment is illustrated where the player's third decision or pick in the game resulted in a credit value or value symbol 103i. The number of credits associated with the value symbol is one hundred. Therefore, the gaming device provides the player with the value or number of credits associated with the value symbol 103i plus any awards associated with symbol combinations indicated by the paylines 52a, 52b and 52c in the game. The gaming device also evaluates the symbols indicated by each of the activated or wagered on paylines (i.e., paylines 52a, 52b and 52c) in the bonus game. Payline 52a indicates three A symbols (i.e., an A symbol plus two wild symbols which substitute for two A symbols) which provides an award of twenty-five as indicated by paytable 113 in FIG. 3B. Payline 52b indicates three G symbols which provides an award of five. Payline 52c indicates a symbol combination including three B symbols which provides an award of twenty. The total award provided to the player in this example is the total bet of fifteen multiplied by the total accumulated award of fifty to provide an award of seven hundred fifty. The credit value or value of one hundred is added to this award to provide a total award of eight hundred fifty in the bonus game as indicated by the paid display 110. This award is added to the player's previous total award of four hundred eighty-five to give the player a new total award of one thousand three hundred thirty-five.
Referring now to FIG. 5, another example of the above embodiment is illustrated where the credit value or value symbol includes a modifier. In this embodiment, the modifier modifies the player's total bet in the game to provide the value to the player. For example, the credit value or value symbols 103i indicates that the value equals 5× the total bet indicated by the total bet display 108. The total bet is fifteen. Therefore, the value of the credit value symbol or value symbol 103i is fifteen multiplied by five or seventy-five. This amount is added to the awards associated with the symbol combinations described above, which is fifty multiplied by the total bet of fifteen or seven hundred fifty credits. The total award provided by the bonus game is eight hundred twenty-five as indicated by the paid display 110. The new total award is therefore four hundred eighty-five plus eight hundred twenty-five or one thousand three hundred ten as indicated by the credit display 112.
Referring now to FIG. 6, another example of the above embodiment is illustrated where the player picked or selected the first selectable symbol in the bonus game, which revealed a credit value or value symbol 103b. The gaming device provides the value associated with the value symbol 103b to the player and then evaluates the symbols indicated by the activated or wagered on paylines 52a, 52b and 52c in the bonus game. None of the activated paylines indicate winning symbol combinations. Therefore, the gaming device provides the player with the value associated with the picked symbol, which is fifty credits as indicated by the paid display 110, and the bonus game ends. The award of fifty credits is also added to the player's previous total award of four hundred eighty-five to provide a new total award of five hundred thirty-five as indicated by the credit display 112.
In any of the above examples, upon completion of the bonus game, the player may continue to play the base game at the same or different wager level, dispense all of the credits by pressing the cash out button, view pay schedules or paytables by pressing the appropriate buttons, and/or view game instructions by pressing a help button.
In one alternative embodiment, the gaming device re-activates one, a plurality or all of the reels in the bonus game after the player has selected or picked one or more of the selectable symbols on the reels in the bonus game. By re-spinning or re-activating one or more of the reels, the gaming device is creating new symbol combinations in the game which may be one or more winning symbol combinations.
In another alternative embodiment, the player may make any suitable type of decision, including making one or more selections from a group of objects. For example, selecting symbol positions and revealing wild symbols until a selection reveals an end of game indicator or terminator symbol. In another embodiment, the gaming device presents one or more questions and the player provides one or more answers to the questions, problems and/or riddles such as answering a trivia question by selecting an answer from a list provided by the gaming device or machine. The gaming device may also enable the player to take actions to complete one or more required activities. For example, the gaming device includes a plastic hammer and enables the player to use the plastic hammer to tap or contact plastic gophers on the head as the gophers pop out of holes in the cabinet of the gaming device.
In another alternative embodiment, the gaming device enables the player to make any suitable number of decisions, including making one or more different decisions or making one or more decisions from a plurality of different decision types. For example, answering two trivia questions and attempting to tap three gopher heads in a game. The gaming device may also enable the player to make one or more decisions based upon a triggering event. For example, making one decision for each trigger symbol appearing on the reels.
In another alternative embodiment, the gaming device enables the player to make decisions until deciding to stop. For example, selecting symbols on the reels until deciding to stop to avoid revealing a symbol that decreases an outcome or award in a game. In another embodiment, the gaming device enables the player to make decisions until selecting a termination object such as a terminator symbol or terminator. For example, the gaming device enables the player to select symbol positions until revealing a “2×” symbol that doubles the value of all outcomes or awards.
3 In another alternative embodiment, the gaming device enables the player to indicate decisions in any suitable manner, such as indicating decisions by audio. For example, the gaming device enables a player to answer a historical trivia question by saying “Answer A” or “The Queen of England.” The player may also indicate their decisions by using a mechanical device such as a laser pointer, light pen, computer mouse, or even a plastic hammer to select symbol positions in the symbol matrix. The player may also indicate decisions by performing some action such as touching the display screen to indicate a symbol position or inserting more coins in the machine to select an option displayed or otherwise associated with the gaming device.
In a further alternative embodiment, the player's decisions may be triggered using any suitable method, including triggering decisions based upon symbols appearing on the reels. For example, a pre-determined combination of symbols appearing on a pay line triggers decisions to be made by a player. In another embodiment, the gaming device triggers decisions to be made by the player after a random or designated number of spins and/or based upon the result of spins. For example, the decisions are triggered after every spin or only after ten consecutive losing spins. The decisions may also be triggered based upon the amount or type of wager. For example, one decision for each fifty credits wagered by the player on the base game or on a separate game from the base game. The decisions may also be triggered upon the results of prior decisions. For example, a player may gain or lose additional decision opportunities based upon the results of one or more previous decisions by the player. The decisions may also be triggered at random. For example, a random number generator that triggers a decision upon the generation of a prime number or other suitable number.
In another alternative embodiment, the player's decisions result in any type of wild symbols, including wild symbols that replace any other symbol on the reels. For example, a wild symbol that replaces all line pay and scatter pay symbols. In another embodiment, the wild symbols replace a sub-set of symbols. For example, a wild symbol that only replaces half of the line pay symbols. In a further embodiment, the wild symbols increase or decrease the value of any outcomes or awards in a game. For example, a wild symbol that doubles the value of all line pay outcomes or awards in a game.
In a further alternative embodiment, the player's decisions result in any number of wild symbols, including a designated or limited number of wild symbols. For example, a player's decision may generate up to but no more than nine wild symbols in a play of a game. In another embodiment, the player's decision generates an unlimited number of wild symbols. For example, the player's decision may generate more wild symbols than symbol positions associated with the reels, where extra wild symbols are reserved for use in subsequent spins of the reels.
In another alternative embodiment, the player's decisions result in wild symbols being displayed in any symbol position on the reels. In another embodiment, the wild symbols are displayed in a limited area or in specific symbol positions associated with the reels. For example, wild symbols may only appear in the first and last columns or on the first and last reels of a set of reels. In a further embodiment, the wild symbols are fixed in the position in which the wild symbols appear on the reels. For example, a wild symbol in the top row of reel two must remain in that symbol position. The wild symbols may also move from symbol positions in which they appear to one or more other symbol positions. For example, a wild symbol in the top row of reel two may move to the bottom row of reel four in a set of five reels.
In another alternative embodiment, the player's decisions result in any duration of wild symbols, including wild symbols that last for more than one spin or activation of the reels. For example, a wild symbol remains on the reels for three spins of the reels. In another embodiment, the wild symbols only last for one or more pay outs to a player. For example, a wild symbol helps form a line pay and disappears, even if that wild symbol could also help form a different line pay in a play of a game. In another embodiment, the wild symbols last for a random or designated amount of time. For example, a wild symbol may last for five minutes regardless of the number of spins of the reels during that time period.
In a further alternative embodiment, the player's decisions result in any suitable outcomes or awards such as a number of credits, prizes (i.e., a car or a cruise) or free games (i.e., ten free spins). The outcomes or awards may affect the value of other awards. For example, an award that doubles the value of other awards issued during the next ten spins of the reels.
In a further alternative embodiment, the outcomes or awards may be any suitable outcome or award based on a player's decision. For example, the player's decisions result in any suitable amount of awards, including any amount of the award type described above such as an award of one million credits to a player.
In another alternative embodiment, the player's decisions result in any number of awards, including any number of award types described above. For example, an outcome or award including a combination of one hundred credits, seven free spins, and a brand new car.
In a further alternative embodiment, the player's decisions result in awards at any point in time in a game, including outcomes or awards issued after one or more decisions by a player. For example, outcomes or awards may issue after every two decisions by a player. In another embodiment, the outcomes or awards are issued between decisions by a player. For example, the outcomes or awards are issued between a first and second decision by a player in a game. In another embodiment, the outcomes or awards are issued or provided to a player following all decisions by a player in a game. For example, the outcomes or awards are issued after every decision has been made by a player in a game. In a further embodiment, the gaming device provides different types of outcomes or awards at different times in a game. For example, prizes or awards may be provided to a player instantly but free spin awards may issue following all decisions made by the player.
In another alternative embodiment, at least one of the selectable symbols includes a wild symbol or a value symbol which splits into two or more identical symbols. For example, a wild symbol associated with the selectable symbol splits into two identical wild symbols after the selectable symbol is picked by a player. As a result, the additional wild symbols enhance the symbol combination indicated by a payline in a game. In another example, if a value symbol is associated with the picked selectable symbol, the value symbol splits into two identical symbols each providing an identical number of credits to the player. The player therefore receives additional credits in the game. It should be appreciated that one or more of the selectable symbols in a game may include a wild symbol or a value symbol which splits into two or more identical symbols. It should also be appreciated that the wild symbol or value symbol described above may split into a designated number of identical symbols, a randomly determined number of identical symbols or a number of identical symbols determined by a wager made by a player. It should further be appreciated that the value symbol may split into one or more different value symbols (i.e., a value symbol that provides fifty credits and a value symbol that provides one hundred credits). It should also be appreciated that the wild symbol or value symbol may split before (i.e., the wild symbol or value symbol splits and the split symbols are revealed after the player picks the selectable symbol) or after the selectable symbol including the splitting wild symbol or value symbol is picked by the player.
In a further alternative embodiment, one or more of the reels split into two or more identical reels before or after the player picks one of the selectable symbols on the reels. For example, after the player picks one of the selectable symbols on the reels, the reel including the picked selectable symbol reveals the wild symbol or value symbol associated with the picked selectable symbol and splits into two identical reels. The gaming device therefore displays an additional reel. The additional reel provides additional symbols and thereby an enhanced symbol combination in the game. It should be appreciated that one, a plurality or all of the reels may split into two or more identical reels in a game. It should also be appreciated that the reels may split into a designated number of identical reels, a randomly determined number of identical reels or a number of identical reels determined by a wager made by a player. It should further be appreciated that one, a plurality or all of the split reels may be different reels in a game (i.e., display one or more different symbols).
While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but on the contrary is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the claims. It is thus to be understood that modifications and variations in the present invention may be made without departing from the novel aspects of this invention as defined in the claims, and that this application is to be limited only by the scope of the claims.
