Gaming devices which provide players awards in primary or base games are well known. Gaming devices generally require the player to place or make a wager to activate the primary or base game. In many of these gaming devices, 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). Symbols or symbol combinations which are less likely to occur usually provide higher awards.
In such known gaming devices, the amount of the wager made on the primary game by the player may vary. For instance, the gaming device may enable the player to wager a minimum number of credits, such as one credit (e.g., one penny, nickel, dime, quarter or dollar) up to a maximum number of credits, such as five credits. This wager may be made by the player a single time or multiple times in a single play of the primary game. For instance, a slot game may have one or more paylines and the slot game may enable the player to make a wager on each payline in a single play of the primary game. Thus, it is known that a gaming device, such as a slot game, may enable players to make wagers of substantially different amounts on each play of the primary or base game ranging, for example, from 1 credit up to 125 credits (e.g., 5 credits on each of 25 separate paylines). Accordingly, it should be appreciated that different players play at substantially different wagering amounts or levels and at substantially different rates of play.
Secondary or bonus games are also known in gaming devices. The secondary or bonus games usually provide an additional award to the player. Secondary or bonus games usually do not require an additional wager by the player to be activated. Certain secondary or bonus games are activated or hit 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 hit the secondary or bonus game. Part of the enjoyment and excitement of playing certain gaming devices is the occurrence or triggering of the secondary or bonus game (even before the player knows how much the bonus award will be).
Secondary or bonus games which enable a player to combine multiple independent features for the same play of the secondary or bonus game increase player excitement and enjoyment. For example, a gaming device may enable a player to select a first feature of applying a multiplier to any award of that play of the bonus game and also select a second different feature of causing one or more symbols to function as wild symbols for that same play of the bonus game. Enabling a player to select which features to employ for a play of a bonus game (and to combine different features) provides the player a sense of control over the play of the bonus game and thus increases player excitement and enjoyment.
However, combining different features for the same play of a bonus game often non-linearly increases the average expected payout of the bonus game (i.e., the average expected payout of the bonus game is increased more than an increase to the average expected payout of adding the two individual features together). For example, a gaming device with a bonus game that employs the independent features of applying a multiplier to any award and also causing one or more symbols to function as wild symbols non-linearly increases the average expected payout for that play of the bonus game because the increased wild symbols result in an increased probability of winning an award which is then modified by the multiplier. In this example, one employed feature affects another employed feature to cause a non-linear increase to the average expected payout for that play of the bonus game. Such a configuration thus introduces a level of strategy into the bonus game because certain strategic or knowledgeable players will combine independent features which result in a play of a bonus game with a first average expected payout while certain less strategic or less knowledgeable players will combine independent features which result in a play of a bonus game with a second, lower average expected payout. Such a configuration thus reduces the level of excitement and enjoyment for less strategic or less knowledgeable players.
Accordingly, there is a continuing need to provide new and different gaming devices and gaming systems as well as new and different ways to provide bonus awards to players without requiring strategy to maximize the bonus game average expected payout.
In various embodiments, the gaming system, gaming device, and gaming method disclosed herein provides an on-demand bonus game which enables players to combine different, independent features without introducing any significant advantage or disadvantage to players for combining certain features over other features. The gaming system utilizes one or more bonus game supplemental awards to insure that the average expected payout per selected bonus game feature remains the same or substantially the same regardless of which bonus game features or combinations of features are employed for a play of a bonus game. In other words, to account for different combinations of features non-linearly increasing the average expected payout of a bonus game, the gaming system disclosed herein employs bonus game supplemental awards of different average expected values to provide an on-demand bonus game which enables players to combine different, independent features while insuring that the bonus game average expected payout (per feature employed) remains the same or substantially the same.
More specifically, the gaming system of one embodiment disclosed herein maintains a normalization table or database of all possible features and combinations of features which can be selected for a play of a bonus game. The normalization table or database includes, for each different individual feature and each different combination of features: (i) an average expected payout or average expected bonus game award value for a play of a bonus game employing that feature (or that combination of features); and (ii) an average expected bonus game supplemental award value for a play of a bonus game employing that feature (or that combination of features). In this embodiment, the gaming system determines the average expected bonus game supplemental award value for each different individual feature (or each different combination of features) based on the average expected payout for a play of a bonus game employing that feature (or that combination of features) and a target average expected payout per employed feature. Such a configuration provides that each play of the bonus game employing a first quantity of features (regardless of which specific feature(s) are employed) will each have substantially the same first total average expected payout. Such a configuration further provides that each play of the bonus game employing a second, different quantity of features (regardless of which specific feature(s) are employed) will each have substantially the same second, different total average expected payout.
In one example, the gaming system employs a target average expected payout per feature of two-hundred-fifty credits (i.e., each time the player selects to employ a feature, regardless of which feature is selected, the gaming system expects to, on average, payout two-hundred-fifty credits). In this example, as seen in Table 1 below:
In this example, as seen in Table 1 above, combining Feature A and Feature C results in a non-linearly higher average expected value or average expected payout (per bonus game feature employed) because the awarding of extra wilds of Feature C causes an increased probability of generating the winning symbol combinations with at least one minor symbol of Feature A, thus causing Feature A to be more rewarding when combined with Feature C. In other words, while:
In this example, to insure that each feature or feature combination pays out, on average, the same two-hundred-fifty credits per individual feature employed (i.e., the target average expected payout per feature employed), the normalization table or database of the gaming system disclosed herein associates different average expected bonus game supplemental award values to the different features and feature combinations as seen above in Table 1. Accordingly, the gaming system disclosed herein accounts for how one feature may affect another feature and utilizes differing average expected bonus game supplemental award values to normalize such an affect and provide that the average expected payout per feature employed or selected remains the same (or substantially the same) regardless of which feature or combination of features are selected to be utilized in the play of a bonus game.
In operation of one embodiment of the gaming system disclosed herein, the gaming system enables a player to accumulate one or more bonus game feature units in association with one or more plays of a base game. In this embodiment, when the player decides to selectively redeem one or more of that player's accumulated bonus game feature units in exchange for a play of a bonus game, the gaming system enables the player to select which feature or features to employ for that play of the bonus game. Each available feature costs the player one accumulated bonus game feature unit and the player may select any designated combination of features to employ for that play of the bonus game. After selecting which feature or features to employ, the gaming system provides the player a play of the bonus game utilizing the features selected by the player. For the play of the bonus game, the gaming system determines a bonus game outcome and provides the player any bonus game award associated with that determined bonus game outcome.
In addition to providing the player the bonus game award resulting from the play of the bonus game, the gaming system utilizes the maintained normalization table or database to determine a bonus game supplemental award. In one embodiment, this bonus game supplemental award is determined by randomly selecting a value from a weighted value table that is configured such that the average expected value of the weighted value table equals the average expected bonus game supplemental award value associated with the specific feature or combination of features employed for that play of the bonus game. For example, if the player selects to play the bonus game utilizing Feature C of Table 1, then the gaming system determines a bonus game supplemental award value by selecting a value from a weighted value table that has an average expected value of one-hundred-ninety-five credits (i.e., the average expected bonus game supplemental award value associated with Feature C). This determined bonus game supplemental award value is provided to the player in addition to the provided bonus game award associated with the play of the bonus game. Such configuration thus provides that, regardless of which feature or features a player employs for a play of a bonus game and thus regardless of how different features may affect the average expected payout for the play of the bonus game, the average expected award for each play of the bonus game (i.e., the total bonus game award average expected value per feature activated) is normalized or equated and thus players are not provided an advantage nor a disadvantage for combining certain features over other features.
Additional features and advantages are described herein, and will be apparent from the following Detailed Description and the figures.
The present disclosure may be implemented in various configurations for gaming machines, gaming devices, or gaming systems, including but not limited to: (1) a dedicated gaming machine, gaming device, or gaming system wherein the computerized instructions for controlling any games (which are provided by the gaming machine or gaming device) are provided with the gaming machine or gaming device prior to delivery to a gaming establishment: and (2) a changeable gaming machine, gaming device, or gaming system wherein the computerized instructions for controlling any games (which are provided by the gaming machine or gaming device) are downloadable to the gaming machine or gaming device through a data network after the gaming machine or gaming device is in a gaming establishment.

The player can increase the bet by one credit each time the player pushes the bet one button. When the player pushes the bet one button, the number of credits shown in the credit display preferably decreases by one, and the number of credits shown in the bet display preferably increases by one. In another embodiment, one input device is a bet max button (not shown) which enables the player to bet the maximum wager permitted for a game of the gaming device.
In one embodiment, one input device is a cash out button 34. The player may push the cash out button and cash out to receive a cash payment or other suitable form of payment corresponding to the number of remaining credits. In one embodiment, when the player cashes out, a payment device, such as a ticket, payment, or note generator 36 prints or otherwise generates a ticket or credit slip to provide to the player. The player receives the ticket or credit slip and may redeem the value associated with the ticket or credit slip via a cashier (or other suitable redemption system). In another embodiment, when the player cashes out, the player receives the coins or tokens in a coin payout tray. It should be appreciated that any suitable payout mechanisms, such as funding to the player's electronically recordable identification card or smart card, may be implemented in accordance with the gaming device disclosed herein.
In one embodiment, as mentioned above and as seen in
The gaming device may further include a plurality of communication ports for enabling communication of the processor with external peripherals, such as external video sources, expansion buses, game or other displays, a SCSI port, or a keypad.
In one embodiment, as seen in
In one embodiment, the gaming machine may include a sensor, such as a camera, in communication with the processor (and possibly controlled by the processor), that is selectively positioned to acquire an image of a player actively using the gaming device and/or the surrounding area of the gaming device. In one embodiment, the camera may be configured to selectively acquire still or moving (e.g., video) images and may be configured to acquire the images in an analog, digital, or other suitable format. The display devices may be configured to display the image acquired by the camera as well as to display the visible manifestation of the game in split screen or picture-in-picture fashion. For example, the camera may acquire an image of the player and the processor may incorporate that image into the primary and/or secondary game as a game image, symbol or indicia.
Gaming device 10 can incorporate any suitable wagering game as the primary or base game. The gaming machine or device may include some or all of the features of conventional gaming machines or devices. The primary or base game may comprise any suitable reel-type game, card game, cascading or falling symbol game, number game, or other game of chance susceptible to representation in an electronic or electromechanical form, which in one embodiment produces a random outcome based on probability data at the time of or after placement of a wager. That is, different primary wagering games, such as video poker games, video blackjack games, video keno, video bingo or any other suitable primary or base game may be implemented.
In one embodiment, as illustrated in
In an alternative embodiment, rather than determining any outcome to provide to the player by analyzing the symbols generated on any wagered upon paylines as discussed above, the gaming device determines any outcome to provide to the player based on the number of associated symbols which are generated in active symbol positions on the requisite number of adjacent reels (i.e., not on paylines passing through any displayed winning symbol combinations). In this embodiment, if a winning symbol combination is generated on the reels, the gaming device provides the player one award for that occurrence of the generated winning symbol combination. For example, if one winning symbol combination is generated on the reels, the gaming device will provide a single award to the player for that winning symbol combination (i.e., not based on the number of paylines that would have passed through that winning symbol combination). It should be appreciated that because a gaming device that enables wagering on ways to win provides the player one award for a single occurrence of a winning symbol combination and a gaming device with paylines may provide the player more than one award for the same occurrence of a single winning symbol combination (i.e., if a plurality of paylines each pass through the same winning symbol combination), it is possible to provide a player at a ways to win gaming device with more ways to win for an equivalent bet or wager on a traditional slot gaming device with paylines.
In one embodiment, the total number of ways to win is determined by multiplying the number of symbols generated in active symbol positions on a first reel by the number of symbols generated in active symbol positions on a second reel by the number of symbols generated in active symbol positions on a third reel and so on for each reel of the gaming device with at least one symbol generated in an active symbol position. For example, a three reel gaming device with three symbols generated in active symbol positions on each reel includes 27 ways to win (i.e., 3 symbols on the first reel×3 symbols on the second reel×3 symbols on the third reel). A four reel gaming device with three symbols generated in active symbol positions on each reel includes 81 ways to win (i.e., 3 symbols on the first reel×3 symbols on the second reel×3 symbols on the third reel×3 symbols on the fourth reel). A five reel gaming device with three symbols generated in active symbol positions on each reel includes 243 ways to win (i.e., 3 symbols on the first reel×3 symbols on the second reel×3 symbols on the third reel×3 symbols on the fourth reel×3 symbols on the fifth reel). It should be appreciated that modifying the number of generated symbols by either modifying the number of reels or modifying the number of symbols generated in active symbol positions by one or more of the reels modifies the number of ways to win.
In another embodiment, the gaming device enables a player to wager on and thus activate symbol positions. In one such embodiment, the symbol positions are on the reels. In this embodiment, if based on the player's wager, a reel is activated, then each of the symbol positions of that reel will be activated and each of the active symbol positions will be part of one or more of the ways to win. In one embodiment, if based on the player's wager, a reel is not activated, then a designated number of default symbol positions, such as a single symbol position of the middle row of the reel, will be activated and the default symbol position(s) will be part of one or more of the ways to win. This type of gaming machine enables a player to wager on one, more than one or all of the reels and the processor of the gaming device uses the number of wagered on reels to determine the active symbol positions and the number of possible ways to win. In alternative embodiments, (1) no symbols are displayed as generated at any of the inactive symbol positions, or (2) any symbols generated at any inactive symbol positions may be displayed to the player but suitably shaded or otherwise designated as inactive.
In one embodiment wherein a player wagers on one or more reels, a player's wager of one credit may activate each of the three symbol positions on a first reel, wherein one default symbol position is activated on each of the remaining four reels. In this example, as discussed above, the gaming device provides the player three ways to win (i.e., 3 symbols on the first reel×1 symbol on the second reel×1 symbol on the third reel×1 symbol on the fourth reel×1 symbol on the fifth reel). In another example, a player's wager of nine credits may activate each of the three symbol positions on a first reel, each of the three symbol positions on a second reel and each of the three symbol positions on a third reel wherein one default symbol position is activated on each of the remaining two reels. In this example, as discussed above, the gaming device provides the player twenty-seven ways to win (i.e., 3 symbols on the first reel×3 symbols on the second reel×3 symbols on the third reel×1 symbol on the fourth reel×1 symbol on the fifth reel).
In one embodiment, to determine any award(s) to provide to the player based on the generated symbols, the gaming device individually determines if a symbol generated in an active symbol position on a first reel forms part of a winning symbol combination with or is otherwise suitably related to a symbol generated in an active symbol position on a second reel. In this embodiment, the gaming device classifies each pair of symbols which form part of a winning symbol combination (i.e., each pair of related symbols) as a string of related symbols. For example, if active symbol positions include a first cherry symbol generated in the top row of a first reel and a second cherry symbol generated in the bottom row of a second reel, the gaming device classifies the two cherry symbols as a string of related symbols because the two cherry symbols form part of a winning symbol combination.
After determining if any strings of related symbols are formed between the symbols on the first reel and the symbols on the second reel, the gaming device determines if any of the symbols from the next adjacent reel should be added to any of the formed strings of related symbols. In this embodiment, for a first of the classified strings of related symbols, the gaming device determines if any of the symbols generated by the next adjacent reel form part of a winning symbol combination or are otherwise related to the symbols of the first string of related symbols. If the gaming device determines that a symbol generated on the next adjacent reel is related to the symbols of the first string of related symbols, that symbol is subsequently added to the first string of related symbols. For example, if the first string of related symbols is the string of related cherry symbols and a related cherry symbol is generated in the middle row of the third reel, the gaming device adds the related cherry symbol generated on the third reel to the previously classified string of cherry symbols.
On the other hand, if the gaming device determines that no symbols generated on the next adjacent reel are related to the symbols of the first string of related symbols, the gaming device marks or flags such string of related symbols as complete. For example, if the first string of related symbols is the string of related cherry symbols and none of the symbols of the third reel are related to the cherry symbols of the previously classified string of cherry symbols, the gaming device marks or flags the string of two cherry symbols as complete.
After either adding a related symbol to the first string of related symbols or marking the first string of related symbols as complete, the gaming device proceeds as discussed above for each of the remaining classified strings of related symbols which were previously classified or formed from related symbols on the first and second reels.
After analyzing each of the remaining strings of related symbols, the gaming device determines, for each remaining pending or incomplete string of related symbols, if any of the symbols from the next adjacent reel, if any, should be added to any of the previously classified strings of related symbols. This process continues until either each string of related symbols is complete or there are no more adjacent reels of symbols to analyze. In this embodiment, where there are no more adjacent reels of symbols to analyze, the gaming device marks each of the remaining pending strings of related symbols as complete.
When each of the strings of related symbols is marked complete, the gaming device compares each of the strings of related symbols to an appropriate paytable and provides the player any award associated with each of the completed strings of symbols. It should be appreciated that the player is provided one award, if any, for each string of related symbols generated in active symbol positions (i.e., as opposed to a quantity of awards being based on how many paylines that would have passed through each of the strings of related symbols in active symbol positions).
In one embodiment, a base or primary game may be a poker game wherein the gaming device enables the player to play a conventional game of video draw poker and initially deals five cards all face up from a virtual deck of fifty-two cards. Cards may be dealt as in a traditional game of cards or in the case of the gaming device, the cards may be randomly selected from a predetermined number of cards. If the player wishes to draw, the player selects the cards to hold via one or more input devices, such as by pressing related hold buttons or via the touch screen. The player then presses the deal button and the unwanted or discarded cards are removed from the display and the gaming machine deals the replacement cards from the remaining cards in the deck. This results in a final five-card hand. The gaming device compares the final five-card hand to a payout table which utilizes conventional poker hand rankings to determine the winning hands. The gaming device provides the player with an award based on a winning hand and the number of credits the player wagered.
In another embodiment, the base or primary game may be a multi-hand version of video poker. In this embodiment, the gaming device deals the player at least two hands of cards. In one such embodiment, the cards are the same cards. In one embodiment each hand of cards is associated with its own deck of cards. The player chooses the cards to hold in a primary hand. The held cards in the primary hand are also held in the other hands of cards. The remaining non-held cards are removed from each hand displayed and for each hand replacement cards are randomly dealt into that hand. Since the replacement cards are randomly dealt independently for each hand, the replacement cards for each hand will usually be different. The poker hand rankings are then determined hand by hand against a payout table and awards are provided to the player.
In one embodiment, a base or primary game may be a keno game wherein the gaming device displays a plurality of selectable indicia or numbers on at least one of the display devices. In this embodiment, the player selects at least one bit potentially a plurality of the selectable indicia or numbers via an input device such as a touch screen. The gaming device then displays a series of drawn numbers and determine an amount of matches, if any, between the player's selected numbers and the gaming device's drawn numbers. The player is provided an award based on the amount of matches, if any, based on the amount of determined matches and the number of numbers drawn.
In one embodiment, in addition to winning credits or other awards 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 in a 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 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
In another embodiment, the gaming device processor 12 or central controller 56 randomly provides the player one or more plays of one or more secondary games. In one such embodiment, the gaming device does not provide any apparent reason to the player for qualifying to play a secondary or bonus game. In this embodiment, qualifying for a bonus game is not triggered by an event in or based specifically on any of the plays of any primary game. That is, the gaming device may simply qualify a player to play a secondary game without any explanation or alternatively with simple explanations. In another embodiment, the gaming device (or central server) qualifies a player for a secondary game at least partially based on a game triggered or symbol triggered event, such as at least partially based on the play of a primary game.
In one embodiment, the gaming device includes a program which will automatically begin a bonus round after the player has achieved a triggering event or qualifying condition in the base or primary game. In another embodiment, after 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 exponential increase in the number of bonus wagering credits awarded. In one embodiment, the player may redeem extra bonus wagering credits 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 is needed. That is, a player may not purchase entry into a bonus game; rather they must win or earn entry through play of the primary game, thus encouraging play of the primary game. In another embodiment, qualification of the bonus or secondary game is accomplished through a simple “buy-in” by the player—for example, if the player has been unsuccessful at qualifying through other specified activities. In another embodiment, the player must make a separate side-wager on the bonus game or wager a designated amount in the primary game to qualify for the secondary game. In this embodiment, the secondary game triggering event must occur and the side-wager (or designated primary game wager amount) must have been placed to trigger the secondary game.
In one embodiment, as illustrated in
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. 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 as 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, a predetermined game outcome value is determined for each of a plurality of linked or networked gaming devices based on the results of a bingo, keno, or lottery game. In this embodiment, each individual gaming device utilizes one or more bingo, keno, or lottery games to determine the predetermined game outcome value provided to the player for the interactive game played at that gaming device. In one embodiment, the bingo, keno, or lottery game is displayed to the player. In another embodiment, the bingo, keno or lottery game is not displayed to the player, but the results of the bingo, keno, or lottery game determine the predetermined game outcome value for the primary or secondary game.
In the various bingo embodiments, as each gaming device is enrolled in the bingo game, such as upon an appropriate wager or engaging an input device, the enrolled gaming device is provided or associated with a different bingo card. Each bingo card consists of a matrix or array of elements, wherein each element is designated with a separate indicia, such as a number. It should be appreciated that each different bingo card includes a different combination of elements. For example, if four bingo cards are provided to four enrolled gaming devices, the same element may be present on all four of the bingo cards while another element may solely be present on one of the bingo cards.
In operation of these embodiments, upon providing or associating a different bingo card with each of a plurality of enrolled gaming devices, the central controller randomly selects or draws, one at a time, a plurality of the elements. As each element is selected, a determination is made for each gaming device as to whether the selected element is present on the bingo card provided to that enrolled gaming device. This determination can be made by the central controller, the gaming device, a combination of the two, or in any other suitable manner. If the selected element is present on the bingo card provided to that enrolled gaming device, 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. It should be appreciated that in one embodiment, the gaming device requires the player to engage a daub button (not shown) to initiate the process of the gaming device marking or flagging any selected elements.
After one or more predetermined patterns are marked on one or more of the provided bingo cards, a game outcome is determined for each of the enrolled gaming devices based, at least in part, on the selected elements on the provided bingo cards. As discussed above, the game outcome determined for each gaming device enrolled in the bingo game is utilized by that gaming device to determine the predetermined game outcome provided to the player. For example, a first gaming device to have selected elements marked in a predetermined pattern is provided a first outcome of win $10 which will be provided to a first player regardless of how the first player plays in a first game, and a second gaming device to have selected elements marked in a different predetermined pattern is provided a second outcome of win $2 which will be provided to a second player regardless of how the second player plays a second game. It should be appreciated that as the process of marking selected elements continues until one or more predetermined patterns are marked, this embodiment ensures that at least one bingo card will win the bingo game and thus at least one enrolled gaming device will provide a predetermined winning game outcome to a player. It should be appreciated that other suitable methods for selecting or determining one or more predetermined game outcomes may be employed.
In one example of the above-described embodiment, the predetermined game outcome may be based on a supplemental award in addition to any award provided for winning the bingo game as discussed above. In this embodiment, if one or more elements are marked in supplemental patterns within a designated number of drawn elements, a supplemental or intermittent award or value associated with the marked supplemental pattern is provided to the player as part of the predetermined game outcome. For example, if the four corners of a bingo card are marked within the first twenty selected elements, a supplemental award of $10 is provided to the player as part of the predetermined game outcome. It should be appreciated that in this embodiment, the player of a gaming device may be provided a supplemental or intermittent award regardless of whether the enrolled gaming device's provided bingo card wins or does not win the bingo game as discussed above.
In another embodiment, one or more of the gaming devices 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.
In one embodiment, the gaming device disclosed herein is associated with or otherwise integrated with one or more player tracking systems. Player tracking systems enable gaming establishments to recognize the value of customer loyalty through identifying frequent customers and rewarding them for their patronage. In one embodiment, the gaming device and/or player tracking system tracks any player's gaming activity at the gaming device. In one such embodiment, the gaming device includes at least one card reader 38 in communication with the processor. In this embodiment, a player is issued a player identification card which has an encoded player identification number that uniquely identifies the player. When a player inserts their playing tracking card into the card reader to begin a gaming session, the card reader reads the player identification number off the player tracking card to identify the player. The gaming device and/or associated player tracking system timely tracks any suitable information or data relating to the identified player's gaming session. Directly or via the central controller, the gaming device processor communicates such information to the player tracking system. The gaming device and/or associated player tracking system also timely tracks when a player removes their player tracking card when concluding play for that gaming session. In another embodiment, rather than requiring a player to insert a player tracking card, the gaming device utilizes one or more portable devices carried by a player, such as a cell phone, a radio frequency identification tag or any other suitable wireless device to track when a player begins and ends a gaming session. In another embodiment, the gaming device utilizes any suitable biometric technology or ticket technology to track when a player begins and ends a gaming session.
During one or more gaming sessions, the gaming device and/or player tracking 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's account number, the player's card number, the player's first name, the player's surname, the player's preferred name, the player's player tracking ranking, any promotion status associated with the player's player tracking card, the player's address, the player's birthday, the player's anniversary, the player's recent gaming sessions, or any other suitable data. In one embodiment, such tracked information and/or any suitable feature associated with the player tracking system is displayed on a player tracking display 40. In another embodiment, such tracked information and/or any suitable feature associated with the player tracking system is displayed via one or more service windows (not shown) which are displayed on the central display device and/or the upper display device.
In one embodiment, a plurality of the gaming devices 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 may be substantially identical to the LAN gaming system described above, although the number of gaming devices in each system may vary relative to one another.
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 subscriber 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 is 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 the enhanced bandwidth of digital wireless communications may render such technology suitable for some or all communications, 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.
As mentioned above, in one embodiment, the present disclosure may be employed in a server-based gaming system. In one such embodiment, as discussed above, one or more gaming devices are in communication with a central server or controller. The central server or controller may be any suitable server or computing device which includes at least one processor and a memory or storage device. In alternative embodiments, the central server is a progressive controller or another gaming machine in the gaming system. In one embodiment, the memory device of the central server stores different game programs and instructions, executable by a gaming device processor, to control the gaming device. Each executable game program represents a different game or type of game which may be played on one or more of the gaming devices in the gaming system. Such different games may include the same or substantially the same game play with different pay tables. In different embodiments, the executable game program is for a primary game, a secondary game or both. In another embodiment, the game program may be executable as a secondary game to be played simultaneous with the play of a primary game (which may be downloaded to or fixed on the gaming device) or vice versa.
In this embodiment, each gaming device at least includes one or more display devices and/or one or more input devices for interaction with a player. A local processor, such as the above-described gaming device processor or a processor of a local server, is operable with the display device(s) and/or the input device(s) of one or more of the gaming devices.
In operation, the central controller is operable to communicate one or more of the stored game programs to at least one local processor. In different embodiments, the stored game programs are communicated or delivered by embedding the communicated game program in a device or a component (e.g., a microchip to be inserted in a gaming device), writing the game program on a disc or other media, or downloading or streaming the game program over a dedicated data network, internet, or a telephone line. After the stored game programs are communicated from the central server, the local processor executes the communicated program to facilitate play of the communicated program by a player through the display device(s) and/or input device(s) of the gaming device. That is, when a game program is communicated to a local processor, the local processor changes the game or type of game played at the gaming device.
In another embodiment, a plurality of gaming devices at one or more gaming sites may be networked to the 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 one or more progressive awards. In one embodiment, a progressive gaming system 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 progressive gaming system 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 progressive gaming system host site computer is maintained for the overall operation and control of the progressive gaming system. In this embodiment, a progressive gaming system 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 progressive gaming system host site computer. Each central server computer is responsible for all data communication between the gaming device hardware and software and the progressive gaming system host site computer. In one embodiment, an individual gaming machine may trigger a progressive award win. In another embodiment, a central server (or the progressive gaming system host site computer) determines when a progressive award win is triggered. In another embodiment, an individual gaming machine and a central controller (or progressive gaming system host site computer) work in conjunction with each other to determine when a progressive win is triggered, for example through an individual gaming machine meeting a predetermined requirement established by the central controller.
In one embodiment, a progressive award win is triggered based on one or more game play events, such as a symbol-driven trigger. In other embodiments, the progressive award triggering event or qualifying condition may be achieved by exceeding a certain amount of game play (such as number of games, number of credits, or amount of time), or reaching a specified number of points earned during game play. In another embodiment, a gaming device is randomly or apparently randomly selected to provide a player of that gaming device one or more progressive awards. In one such embodiment, the gaming device does not provide any apparent reasons to the player for winning a progressive award, wherein winning the progressive award is not triggered by an event in or based specifically on any of the plays of any primary game. That is, a player is provided a progressive award without any explanation or alternatively with simple explanations. In another embodiment, a player is provided a progressive award at least partially based on a game triggered or symbol triggered event, such as at least partially based on the play of a primary game.
In one embodiment, one or more of the progressive awards are each funded via a side bet or side wager. In this embodiment, a player must place or wager a side bet to be eligible to win the progressive award associated with the side bet. In one embodiment, the player must place the maximum bet and the side bet to be eligible to win one of the progressive awards. In another embodiment, if the player places or wagers the required side bet, the player may wager at any credit amount during the primary game (i.e., the player need not place the maximum bet and the side bet to be eligible to win one of the progressive awards). In one such embodiment, the greater the player's wager (in addition to the placed side bet), the greater the odds or probability that the player will win one of the progressive awards. It should be appreciated that one or more of the progressive awards may each be funded, at least in part, based on the wagers placed on the primary games of the gaming machines in the gaming system, via a gaming establishment or via any suitable manner.
In another embodiment, one or more of the progressive awards are partially funded via a side-bet or side-wager which the player may make (and which may be tracked via a side-bet meter). In one embodiment, one or more of the progressive awards are funded with only side-bets or side-wagers placed. In another embodiment, one or more of the progressive awards are funded based on player's wagers as discussed above as well as any side-bets or side-wagers placed.
In one alternative embodiment, a minimum wager level is required for a gaming device to qualify to be selected to obtain one of the progressive awards. In one embodiment, this minimum wager level is the maximum wager level for the primary game in the gaming machine. In another embodiment, no minimum wager level is required for a gaming machine to qualify to be selected to obtain one of the progressive awards.
In another embodiment, a plurality of players at a plurality of linked gaming devices in a gaming system participate in a group gaming environment. In one embodiment, a plurality of players at a plurality of linked gaming devices work in conjunction with one another, such as by playing together as a team or group, to win one or more awards. In one such embodiment, any award won by the group is shared, either equally or based on any suitable criteria, amongst the different players of the group. In another embodiment, a plurality of players at a plurality of linked gaming devices compete against one another for one or more awards. In one such embodiment, a plurality of players at a plurality of linked gaming devices participate in a gaming tournament for one or more awards. In another embodiment, a plurality of players at a plurality of linked gaming devices play for one or more awards wherein an outcome generated by one gaming device affects the outcomes generated by one or more linked gaming devices.

In operation of this illustrated embodiment, as described above, the gaming system enables a player to play a primary game upon placing a wager as indicated in block 102.
In association with the play of the primary game, the gaming system determines if a bonus game feature unit accumulation event has occurred as indicated in diamond 104. In one embodiment, a bonus game feature unit accumulation event occurs in association with a displayed event of a play of a primary game at one or more of the gaming devices in the gaming system. In another embodiment, a bonus game feature unit accumulation event occurs independent of any displayed event in any play of any primary game at any of the gaming devices in the gaming system.
If a bonus game feature unit accumulation event occurs, the gaming system provides the player one or more bonus game feature units as indicated in block 106. In one embodiment, each bonus game feature unit represents a play of a bonus game in which a player selected feature is employed for that play of the bonus game. As described below, a plurality of different bonus game feature units can be simultaneously redeemed such that a plurality of different features are each employed for a single play of a bonus game.
In one embodiment, each bonus game feature unit has a target, theoretical or average expected value. In this embodiment, each bonus game feature unit has the same target value which the gaming system is configured to, on average, provide to a player for the redemption of that bonus game feature unit. It should be appreciated that prior to being redeemed, each different bonus game feature unit has a theoretical value because an actual value for each redeemed bonus game feature unit cannot be determined until one or more random determinations occur in association with the redemption of such bonus game feature units (as described below).
After accumulating one or more bonus game feature units or if no bonus game feature unit accumulation event occurs, the gaming system determines if the player has selected to redeem at least one accumulated bonus game feature unit for a play of a bonus game as indicated in diamond 108.
If the player has not selected to redeem at least one accumulated bonus game feature unit, the gaming system returns to block 102 and, as described above, enables the player to play a primary game upon placing another wager.
On the other hand, if the player has selected to redeem at least one accumulated bonus game feature unit, the gaming system displays the available features of the bonus game to the player as indicated in block 110. In different embodiments, the features available for activation in the play of the bonus game include, but are not limited to:
After displaying the available features for the play of the bonus game, for each accumulated bonus game feature unit; the gaming system enables the player to select a feature to activate for the play of the bonus game as indicated in block 112. In one embodiment, the gaming system enables the player to select a feature to activate for each of a designated quantity of features (i.e., up to a designated quantity of features can be simultaneously activated for a single play of the bonus game). For example, if the player has at least four bonus game feature units, the gaming system enables the player to select up to four different features to activate for the play of the bonus game. In another embodiment, the gaming system enables the player to select a feature to activate for each of the player's accumulated quantity of bonus game feature units (i.e., there is no preset limit to the quantity of features that can be simultaneously activated for a single play of the bonus game).
In one embodiment, each individual feature has an individual average expected value or average expected payout. That is, each individual feature has an individual average expected value or average expected payout which represents, on average, the additional payout of the bonus game when that feature is employed (compared to when that feature is not employed). In addition to each individual feature being associated with an individual average expected value or average expected payout, combinations of features have average expected values or average expected payouts. These average expected values or average expected payouts represents, on average, the additional payout of the bonus game when a particular combination of features are employed (compared to when that combination of features is not employed). It should be appreciated that certain combinations of features have an average expected payout that is non-linear to the sum of the average expected payouts of the individual features which form that combination of features. That is, certain features, when combined together, affect each other and result in a different average expected payout than the average expected payout of those features being awarded individually during separate plays of the bonus game.
After the player selects at least one bonus game feature to activate for the play of the bonus game, the gaming system deducts one bonus game feature unit for each bonus game feature selected and activates the selected feature or combination of selected features as indicated in blocks 114 and 116 of
After activating one or more features for the play of the bonus game, the gaming system initiates a play of the bonus game employing the activated features and determines and displays a bonus game outcome for the play of the bonus game as indicated in block 118. The gaming system then determines, displays and provides the player the bonus game award associated with the displayed bonus game outcome as indicated in block 120. It should be appreciated that since the actual bonus game award provided to the player depends on one or more random determinations, the value of the actual bonus game award provided to the player may be the same as or different than the average expected payout associated with the play of the bonus game employing the feature or combination of features that the player selected to activate.
In addition to providing a bonus game award for the play of the bonus game, the gaming system also determines, based on the below-described weighted table having an average expected value equal to the average expected payout of the selected feature or combination of features, a bonus game supplemental award for the play of the bonus game as indicated in block 122. In one such embodiment, the gaming system determines the bonus game supplemental award utilizing at least one random determination that results, on average, in a bonus game supplemental award value that when combined with the average expected payout associated with the play of the bonus game employing the features that the player selected to activate results in a designated total bonus game award. In this embodiment, the resulting designated total bonus game award divided by the quantity of bonus game feature units redeemed for that play of the bonus game is equal to (or substantially equal to) the target value of the bonus game feature unit.
The gaming system then displays the determined bonus game supplemental award and provides this determined bonus game supplemental award to the player to conclude the play of the selectively redeemed bonus game as indicated in block 124. Accordingly, the gaming system of this embodiment provides the player a total bonus game award including the determined bonus game award and the determined bonus game supplemental award.
Specifically, in one embodiment, to determine the bonus game supplemental award, the gaming system maintains a normalization table or database of all possible features and combinations of features which can be selected for a play of a bonus game. The normalization table or database includes, for each different individual feature and each different combination of features: (i) an average expected payout or average expected bonus game award value for a play of a bonus game employing that feature (or that combination of features); and (ii) an average expected bonus game supplemental award value for a play of a bonus game employing that feature (or that combination of features). In this embodiment, the gaming system determines the average expected bonus game supplemental award value for each different individual feature (or each different combination of features) based on the average expected payout for a play of a bonus game employing that feature (or that combination of features) and the target average expected payout per employed feature. That is, for each different individual feature (or each different combination of different features), the gaming system accounts for the average expected payout associated with the play of the bonus game employing that feature (or combination of features), the target value associated with each bonus game feature unit and the quantity of bonus game feature units redeemed for the play of the bonus game to determine the average expected bonus game supplemental award value. Such a configuration provides that, regardless of which feature or combination of features is employed, for each individual feature and each combination of features, the average expected payout for that feature (or that combination of features) and the average expected bonus game supplemental award value for that feature (or that combination of features) result in the same average expected payout per feature and the same award value is provided to the player, on average, for each redeemed bonus game feature unit.

In one embodiment, in determining the bonus game supplemental award, the gaming system utilizes the weighting of the top bonus game supplemental award value for a play of a bonus game having the player selected feature or combination of features in a weighted bonus game supplemental award value table or database. Such utilization provides that the average expected value of the weighted table or database equals (or substantially equals) the average expected value of the bonus game supplemental award for the play of the bonus game employing the player selected feature or combination of features. In this embodiment, the gaming system randomly selects a value from the weighted value table or database, wherein on average, the selected value will equal (or substantially equal to) the average expected value of the bonus game supplemental award for the play of the bonus game employing the feature or combination of features that the player selected to activate. It should be appreciated that since the determined bonus game supplemental award provided to the player depends on one or more random determinations, the value of the bonus game supplemental award provided to the player may be the same as or different than the average expected bonus game supplemental award value associated with the play of the bonus game employing the features that the player selected to activate.

More specifically, the minor symbol upgrade feature 156 includes transforming at least one winning symbol combination with at least one minor symbol to a winning symbol combination with at least one major symbol (and thus increasing the payout for certain winning symbol combinations). For example, for this feature, the determination of which minor symbols to transform occurs with choosing the highest minor symbol generated. Once the minor symbols are chosen, all occurrences of those minor symbols which are generated are transformed into major symbols.
The credits award for every major symbol feature 158 includes, for every winning symbol combination which includes a major symbol, a value selected from a weighted table or database and that value is provided to the player. For example, a value is selected from the following weighted table or database:
and the selected value is provided to the player.
The random wild feature 160 includes adding random wild symbols to the reels (to increase the probability of each winning symbol combination being generated). For example, the following “number of wild symbols” weighted table or database is queried to determine the number of wild symbols added to the reels.
After determining the number of wild symbols to add to the reel, for each of the determined number of wild symbols to be added, the following “wild symbol reel” weighted table or database is queried, to determine the reel that wild symbol will be associated with.
For each of the determined number of wild symbols, the wild symbol is then randomly placed at a symbol position of the determined reel.
The wild reel feature 162 includes spinning a reel including wild symbols and transparent ghosts or transparent blank symbols over one or more reels to randomly generate zero, one or more wild symbols. For example, a reel including the following configuration is utilized over the third reel for the wild reel feature:
The additional credits per winning payline feature 164 includes providing the player an additional quantity of credits for every payline with a winning symbol combination. For example, the gaming system provides the player an additional twenty credits for each payline determined to be a winning payline during the bonus game.
The random 2× multiplier symbol feature 166 includes selecting a reel and randomly placing a 2× multiplier symbol on that reel. For example, a reel is selected from the following “2× multiplier reel” weighted table or database:
and a single 2× multiplier symbol is randomly associated with one of the symbol positions of the selected reel.

In one embodiment, a bonus game feature unit accumulation event occurs based on an amount coin-in. In this embodiment, the gaming system determines if an amount of coin-in wagered at one or more gaming devices in the gaming system reaches or exceeds a designated amount of coin-in (i.e., a threshold coin-in amount). Upon the amount of coin-in wagered at one or more gaming devices in the gaming system reaching or exceeding the bonus threshold coin-in amount, the gaming system causes the bonus game feature unit accumulation event to occur. In different embodiments, the threshold coin-in amount is predetermined, randomly determined, determined based on a player'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'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 another embodiment of the gaming system disclosed herein, a bonus game feature unit accumulation event occurs based on an amount coin-out. In this embodiment, the gaming system determines if an amount of coin-out provided by one or more gaming devices in the gaming system reaches or exceeds a designated amount of coin-out (i.e., a threshold coin-out amount). Upon the amount of coin-out provided at one or more gaming devices in the gaming system reaching or exceeding the threshold coin-out amount, the gaming system causes the bonus game feature unit accumulation event to occur. In different embodiments, the threshold coin-out amount is predetermined, randomly determined, determined based on a player'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'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 another embodiment of the gaming system disclosed herein, a bonus game feature unit accumulation event occurs based on a predefined variable reaching a defined parameter threshold. For example, when the 500,000th player has played a gaming device of the gaming system (ascertained from a player tracking system), the bonus game feature unit accumulation event occurs. 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 machine (which gaming device is the first to contribute $250,000), a number of gaming devices active, or any other parameter that defines a suitable threshold.
In another embodiment of the gaming system disclosed herein, a bonus game feature unit accumulation event occurs 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 central controller/gaming device processor recognizes the player's identification (via the player tracking system) when the player inserts or otherwise associates their player tracking card with the gaming device. The central server/gaming device processor determines the player tracking level of the player and if the current player tracking level defined by the gaming system operator is eligible for the bonus game feature unit accumulation event. In one embodiment, the gaming system operator defines minimum bet levels required for the bonus game feature unit accumulation event to occur based on the player's card level.
In another embodiment of the gaming system disclosed herein, a bonus game feature unit accumulation event occurs based on a system determination, including one or more random selections by the central controller. In one embodiment, as discussed above, the central controller tracks all active gaming devices and the wagers they placed. Each gaming device has its own entry defining its state as either active or inactive and also defining the values of the wagers from that gaming device. In one embodiment, active status means that the gaming device is being actively played by a player and enrolled/inactive status means that the gaming device is not being actively played by a player. The active status requirements can be based on any suitable number of satisfied criteria or defined in any suitable manner by the implementer of the gaming system. In one such embodiment, based on the gaming device's state as well as one or more wager pools associated with the gaming device, the central controller determines whether the bonus game feature unit accumulation event to occur. In one such embodiment, the player who consistently places a higher wager is more likely to be associated with an occurrence of the bonus game feature unit accumulation event 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 the bonus game feature unit accumulation event will occur may be 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 bonus game feature unit accumulation event to occur.
In another embodiment of the gaming system disclosed herein, a bonus game feature unit accumulation event occurs based on a determination of if any numbers allotted to a gaming device match a randomly selected number. In this embodiment, upon or prior to each play of each gaming device, a gaming device selects a random number from a range of numbers and during each primary game, the gaming device 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, the bonus game feature unit accumulation event will occur.
In another embodiment, a bonus game feature unit accumulation event occurs independent of any displayed event in any play of any game of any of the gaming devices in the gaming system. That is, the bonus game feature unit accumulation event is based on a trigger that is unknown to the player (i.e., a mystery trigger). 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 gaming devices in the gaming system and determines, based on these tracked events, whether a bonus game feature unit accumulation event will occur. In another embodiment, the gaming system defines one or more game play parameters, wherein each time a player's tracked game play activity satisfies the defined parameter, the bonus game feature unit accumulation event occurs. It should be appreciated that any suitable manner of causing the bonus game feature unit accumulation event to be provided may be implemented in accordance with the gaming system and method disclosed herein.
In different embodiments, one or more bonus game feature unit accumulation events may occur for each play of a primary game. In one such embodiment, each play of a primary game in which a plurality of paylines are wagered on provides the player multiple opportunities to accumulate bonus game feature units. For example, for one play of a primary game, a first bonus game feature unit generating symbol combination on a first payline may cause a first bonus game feature unit accumulation event which results in an accumulation of a first quantity of bonus game feature units and a second bonus game feature unit generating symbol combination on a second payline may cause a second bonus game feature unit accumulation event which results in an accumulation of a second quantity of bonus game feature units. Accordingly, in association with a play of a primary game, a plurality of events may occur which result in a plurality of quantities of bonus game feature units provided to the player.
In one embodiment, the gaming machines of the gaming system are operable to cause multiple bonus game feature unit accumulation events to occur for multiple players at multiple linked gaming machines at the same time or substantially the same time. Alternatively, the gaming machines of the gaming system are operable to cause multiple bonus game feature unit accumulation events to occur for multiple players at multiple linked gaming machines in an overlapping or sequential manner. In one such embodiment, an occurrence of a bonus game feature unit accumulation event results in a plurality of players each receiving one or more bonus game feature units.
In one embodiment, the gaming system enables a player to store any accumulated bonus game feature units in association with a player tracking account. In this embodiment, if a player does not elect to redeem one or more accumulated bonus game feature units for a play of a bonus game, the gaming system stores any bonus game feature units in that player's account to be redeemed at a later time. In this embodiment, since the bonus game feature units are stored by the gaming system in the player's account, such bonus game feature units are transferable and the player may earn and redeem such bonus game feature units at a plurality of different gaming devices in the gaming establishment.
In one embodiment, the gaming system establishes a gaming device account for accumulating bonus game feature units. In such embodiments, either a player or a gaming establishment operator can elect for a gaming device to participate in the accumulation of bonus game feature units, wherein if the gaming device is determined to participate in the accumulation of bonus game feature units, the gaming system establishes an account (or otherwise accesses a previously established account) for the gaming device. It should be appreciated that in this embodiment, the accumulation of one or more bonus game feature units are stored in an account associated with the gaming device and are not specific to the player that is playing that gaming device at any particular point in time.
In another embodiment, accumulated bonus game feature units are associated with an expiration date and time. In this embodiment, the gaming system/gaming device is configured to communicate to the player the proximity of the expiration of any stored bonus game feature units (i.e., “your bonus game feature units will expire at 6:00 am tomorrow”). In one embodiment, such notice of expiration of stored bonus game feature units is at the player's currently played gaming device. In another embodiment, such notice of expiration of stored bonus game feature units is external from the player's currently played gaming device, such as via e-mail. In different embodiments, bonus game feature units accumulated at different times are redeemed in order of expiration (first to expire shows first), or in order of first earned basis.
In another embodiment, the gaming system enables a player to purchase a designated quantity of bonus game feature units. In this embodiment, rather than accumulating bonus game feature units based on one or more aspects of game play, the gaming system enables the player to directly or indirectly purchase one or more bonus game feature units. In another embodiment, the gaming system funds a player's account with one or more bonus game feature units in association with a promotion. In this embodiment, the central server provides one or more bonus game feature units to a player for accepting or participating in a promotion. For example, in exchange for signing up for a gaming establishment's player loyalty club, for visiting a gaming establishment's website or some activity thereon, such as learning about a new game, or for trying a new game, the central server funds a player's account with one or more bonus game feature units. In another embodiment, the central server is configured to fund a player's account with modified quantities of bonus game feature units for a bonus game feature unit accumulation event occurring in association with a promotion. For example, during a designated promotion time at a gaming establishment, the central server funds a player's account with double bonus game feature units compared to the quantity of bonus game feature units the player would have received during the non-promotion time. In another embodiment, a bonus game feature unit accumulation event occurs in association with a player purchasing one or more items.
In one alternative embodiment, the gaming system selects one or more of the bonus game features to employ for a play of a bonus game. In one such embodiment, the player indicates a quantity of accumulated bonus game feature units to redeem and the gaming system selects a bonus game feature to employ for one or more of these redeemed bonus game feature units. In another embodiment, the gaming system selects at least one bonus game feature to employ for a play of a bonus game and the player selects at least one bonus game feature to employ for the play of the bonus game.
In various embodiments, one or more of:
It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
