The present invention relates generally to gaming machines, and methods for playing wagering games, and more particularly, to gaming machines with separately selectable wagering games.
Gaming machines, such as slot machines, video poker machines and the like, have been a cornerstone of the gaming industry for several years. Generally, the popularity of such machines with players is dependent on the likelihood (or perceived likelihood) of winning money at the machine and the intrinsic entertainment value of the machine relative to other available gaming options. Where the available gaming options include a number of competing machines and the expectation of winning at each machine is roughly the same (or believed to be the same), players are likely to be attracted to the most entertaining and exciting machines. Shrewd operators consequently strive to employ the most entertaining and exciting machines, features, and enhancements available because such machines attract frequent play and hence increase profitability to the operator. Therefore, there is a continuing need for gaming machine manufacturers to continuously develop new games and improved gaming enhancements that will attract frequent play through enhanced entertainment value to the player.
One concept that has been successfully employed to enhance the entertainment value of a game is the concept of a “secondary” or “bonus” game that may be played in conjunction with a “base” game. The bonus game may comprise any type of game, either similar to or completely different from the base game, which is entered upon the occurrence of a selected event or outcome in the base game. Generally, bonus games provide a greater expectation of winning than the base game and may also be accompanied with more attractive or unusual video displays and/or audio. Bonus games may additionally award players with “progressive jackpot” awards that are funded, at least in part, by a percentage of coin-in from the gaming machine or a plurality of participating gaming machines.
In most gaming machines, the base games and bonus games, including progressive jackpots and other communal games, are linked together as a single integrated package. Thus, for a given gaming machine, the same base game always triggers the same bonus game or set of bonus games. Of course, game designers try to match base games and bonus games that compliment one another so that the combination provides an enhanced overall gaming experience. But while the above arrangement has mostly proven successful, it provides players, casino operators, and/or gaming machine manufacturers with few options. For example, consider the case where the base game is highly popular among players, but the associated bonus game is not (or vice versa). If players want to play the base game, they must tolerate the bonus game (and vice versa), which may dampen their enthusiasm for the base game. For casino operators, swapping out the less popular bonus game requires recertification of the entire package, as the two games are linked together. Indeed, in some regulatory jurisdictions, recertification is required even for changes to just the features of the base games and/or bonus games.
Accordingly, there is a continuing need to develop gaming machines with more options for players, casino operators, and/or gaming machine manufacturers. More particularly, there is a need to develop gaming machines where the base games and/or bonus games, and/or the features thereof, may be selected as needed by players, casino operators, and/or gaming machine manufacturers.
According to one aspect of the present invention, a gaming machine for conducting a wagering game comprises a wager input device for receiving a wager input from a player for playing a base wagering game and at least one display operable to display an outcome of the base wagering game, the outcome of the base wagering game randomly being selected from a plurality of base wagering game outcomes. The at least one display is further operable to display an outcome of a bonus wagering game, the outcome of the bonus wagering game being randomly selected from a plurality of bonus wagering game outcomes. The base wagering game and the bonus wagering game are downloaded independently of one another to the gaming machine.
According to another aspect of the invention, a method of conducting a wagering game on a gaming machine comprises downloading a primary wagering game to the gaming machine, the primary wagering game being selected from a plurality of primary wagering games. The method further comprises downloading a secondary wagering game to the gaming machine independently of the primary wagering game, the secondary wagering game being selected from a plurality of secondary wagering games. A wager input is received at the gaming machine from a player for playing the primary wagering game, and an outcome of the primary wagering game is displayed, the outcome of the primary wagering game being randomly selected from a plurality of primary wagering game outcomes. An outcome of the secondary wagering game is also displayed, the outcome of the secondary wagering game being randomly selected from a plurality of secondary wagering game outcomes.
According to yet another aspect of the invention, a system for downloading wagering games to a gaming machine comprises a network and a storage unit connected to the network, the storage unit storing a plurality of base wagering game packages and a plurality of bonus wagering game packages. The system further comprises a game server connected to the storage unit, the game server configured to access the base wagering game packages and the bonus wagering game packages stored on the storage unit. At least one gaming machine is connected to the game server, the gaming machine configured to receive the base wagering game packages and the bonus wagering game packages from the storage unit. The game server is further configured to download at least one of the base wagering game packages and at least one of the bonus wagering game packages independently of each other to the gaming machine.
Additional aspects of the invention will be apparent to those of ordinary skill in the art in view of the detailed description of various embodiments, which is made with reference to the drawings, a brief description of which is provided below.

Referring to
The gaming machine 10 comprises a housing 12 and includes input devices, including a value input device 18 and a player input device 24. For output the gaming machine 10 includes a primary display 14 for displaying information about the base wagering game. The primary display 14 can also display information about a bonus wagering game and a progressive wagering game. The gaming machine 10 may also include a secondary display 16 for displaying game events, game outcomes, and/or signage information. While these typical components found in the gaming machine 10 are described below, it should be understood that numerous other elements may exist and may be used in any number of combinations to create various forms of a gaming machine 10.
The value input device 18 may be provided in many forms, individually or in combination, and is preferably located on the front of the housing 12. The value input device 18 receives currency and/or credits that are inserted by a player. The value input device 18 may include a coin acceptor 20 for receiving coin currency (see
The player input device 24 comprises a plurality of push buttons 26 on a button panel for operating the gaming machine 10. In addition, or alternatively, the player input device 24 may comprise a touch screen 28 mounted by adhesive, tape, or the like over the primary display 14 and/or secondary display 16. The touch screen 28 contains soft touch keys 30 denoted by graphics on the underlying primary display 14 and used to operate the gaming machine 10. The touch screen 28 provides players with an alternative method of input. A player enables a desired function either by touching the touch screen 28 at an appropriate touch key 30 or by pressing an appropriate push button 26 on the button panel. The touch keys 30 may be used to implement the same functions as push buttons 26. Alternatively, the push buttons 26 may provide inputs for one aspect of the operating the game, while the touch keys 30 may allow for input needed for another aspect of the game.
The various components of the gaming machine 10 may be connected directly to, or contained within, the housing 12, as seen in
The operation of the base wagering game is displayed to the player on the primary display 14. The primary display 14 can also display the bonus game associated with the base wagering game. The primary display 14 may take the form of a cathode ray tube (CRT), a high resolution LCD, a plasma display, an LED, or any other type of display suitable for use in the gaming machine 10. As shown, the primary display 14 includes the touch screen 28 overlaying the entire display (or a portion thereof) to allow players to make game-related selections. Alternatively, the primary display 14 of the gaming machine 10 may include a number of mechanical reels to display the outcome in visual association with at least one payline 32. In the illustrated embodiment, the gaming machine 10 is an “upright” version in which the primary display 14 is oriented vertically relative to the player. Alternatively, the gaming machine may be a “slant-top” version in which the primary display 14 is slanted at about a thirty-degree angle toward the player of the gaming machine 10.
A player begins play of the base wagering game by making a wager via the value input device 18 of the gaming machine 10. A player can select play by using the player input device 24, via the buttons 26 or the touch screen keys 30. The base game consists of a plurality of symbols arranged in an array, and includes at least one payline 32 that indicates one or more outcomes of the base game. Such outcomes are randomly selected in response to the wagering input by the player. At least one of the plurality of randomly-selected outcomes may be a start-bonus outcome, which can include any variations of symbols or symbol combinations triggering a bonus game.
In some embodiments, the gaming machine 10 may also include a player information reader 52 that allows for identification of a player by reading a card with information indicating his or her true identity. The player information reader 52 is shown in
Depicted in
The player-accessible value input device 118 may comprise, for example, a slot located on the front, side, or top of the casing 112 configured to receive credit from a stored-value card (e.g., casino card, smart card, debit card, credit card, etc.) inserted by a player. In another aspect, the player-accessible value input device 118 may comprise a sensor (e.g., an RF sensor) configured to sense a signal (e.g., an RF signal) output by a transmitter (e.g., an RF transmitter) carried by a player. The player-accessible value input device 118 may also or alternatively include a ticket reader, or barcode scanner, for reading information stored on a credit ticket, a card, or other tangible portable credit or funds storage device. The credit ticket or card may also authorize access to a central account, which can transfer money to the handheld gaming machine 110.
Still other player-accessible value input devices 118 may require the use of touch keys 130 on the touch-screen display (e.g., primary display 114 and/or secondary display 116) or player input devices 124. Upon entry of player identification information and, preferably, secondary authorization information (e.g., a password, PIN number, stored value card number, predefined key sequences, etc.), the player may be permitted to access a player's account. As one potential optional security feature, the handheld gaming machine 110 may be configured to permit a player to only access an account the player has specifically set up for the handheld gaming machine 110. Other conventional security features may also be utilized to, for example, prevent unauthorized access to a player's account, to minimize an impact of any unauthorized access to a player's account, or to prevent unauthorized access to any personal information or funds temporarily stored on the handheld gaming machine 110.
The player-accessible value input device 118 may itself comprise or utilize a biometric player information reader which permits the player to access available funds on a player's account, either alone or in combination with another of the aforementioned player-accessible value input devices 118. In an embodiment wherein the player-accessible value input device 118 comprises a biometric player information reader, transactions such as an input of value to the handheld device, a transfer of value from one player account or source to an account associated with the handheld gaming machine 110, or the execution of another transaction, for example, could all be authorized by a biometric reading, which could comprise a plurality of biometric readings, from the biometric device.
Alternatively, to enhance security, a transaction may be optionally enabled only by a two-step process in which a secondary source confirms the identity indicated by a primary source. For example, a player-accessible value input device 118 comprising a biometric player information reader may require a confirmatory entry from another biometric player information reader 152, or from another source, such as a credit card, debit card, player ID card, fob key, PIN number, password, hotel room key, etc. Thus, a transaction may be enabled by, for example, a combination of the personal identification input (e.g., biometric input) with a secret PIN number, or a combination of a biometric input with a fob input, or a combination of a fob input with a PIN number, or a combination of a credit card input with a biometric input. Essentially, any two independent sources of identity, one of which is secure or personal to the player (e.g., biometric readings, PIN number, password, etc.) could be utilized to provide enhanced security prior to the electronic transfer of any funds. In another aspect, the value input device 118 may be provided remotely from the handheld gaming machine 110.
The player input device 124 comprises a plurality of push buttons on a button panel for operating the handheld gaming machine 110. In addition, or alternatively, the player input device 124 may comprise a touch screen 128 mounted to a primary display 114 and/or secondary display 116. In one aspect, the touch screen 128 is matched to a display screen having one or more selectable touch keys 130 selectable by a user's touching of the associated area of the screen using a finger or a tool, such as a stylus pointer. A player enables a desired function either by touching the touch screen 128 at an appropriate touch key 130 or by pressing an appropriate push button 126 on the button panel. The touch keys 130 may be used to implement the same functions as push buttons 126. Alternatively, the push buttons may provide inputs for one aspect of the operating the game, while the touch keys 130 may allow for input needed for another aspect of the game. The various components of the handheld gaming machine 110 may be connected directly to, or contained within, the casing 112, as seen in
The operation of the base wagering game on the handheld gaming machine 110 is displayed to the player on the primary display 114. The primary display 114 can also display the bonus game associated with the base wagering game. The primary display 114 preferably takes the form of a high resolution LCD, a plasma display, an LED, or any other type of display suitable for use in the handheld gaming machine 110. The size of the primary display 114 may vary from, for example, about a 2-3″ display to a 15″ or 17″ display. In at least some aspects, the primary display 114 is a 7″-10″ display. As the weight of and/or power requirements of such displays decreases with improvements in technology, it is envisaged that the size of the primary display may be increased. Optionally, coatings or removable films or sheets may be applied to the display to provide desired characteristics (e.g., anti-scratch, anti-glare, bacterially-resistant and anti-microbial films, etc.). In at least some embodiments, the primary display 114 and/or secondary display 116 may have a 16:9 aspect ratio or other aspect ratio (e.g., 4:3). The primary display 114 and/or secondary display 116 may also each have different resolutions, different color schemes, and different aspect ratios.
As with the free standing gaming machine 10, a player begins play of the base wagering game on the handheld gaming machine 110 by making a wager (e.g., via the value input device 18 or an assignment of credits stored on the handheld gaming machine via the touch screen keys 130, player input device 124, or buttons 126) on the handheld gaming machine 110. In at least some aspects, the base game may comprise a plurality of symbols arranged in an array, and includes at least one payline 132 that indicates one or more outcomes of the base game. Such outcomes are randomly selected in response to the wagering input by the player. At least one of the plurality of randomly selected outcomes may be a start-bonus outcome, which can include any variations of symbols or symbol combinations triggering a bonus game.
In some embodiments, the player-accessible value input device 118 of the handheld gaming machine 110 may double as a player information reader 152 that allows for identification of a player by reading a card with information indicating the player's identity (e.g., reading a player's credit card, player ID card, smart card, etc.). The player information reader 152 may alternatively or also comprise a bar code scanner, RFID transceiver or computer readable storage medium interface. In one presently preferred aspect, the player information reader 152, shown by way of example in
Turning now to
The controller 34 is also coupled to the system memory 36 and a money/credit detector 38. The system memory 36 may comprise a volatile memory (e.g., a random-access memory (RAM)) and a non-volatile memory (e.g., an EEPROM). The system memory 36 may include multiple RAM and multiple program memories. The money/credit detector 38 signals the processor that money and/or credits have been input via the value input device 18. Preferably, these components are located within the housing 12 of the gaming machine 10. However, as explained above, these components may be located outboard of the housing 12 and connected to the remainder of the components of the gaming machine 10 via a variety of different wired or wireless connection methods.
As seen in
Communications between the controller 34 and both the peripheral components of the gaming machine 10 and external systems 50 occur through input/output (I/O) circuits 46, 48. More specifically, the controller 34 controls and receives inputs from the peripheral components of the gaming machine 10 through the input/output circuits 46. Further, the controller 34 communicates with the external systems 50 via the I/O circuits 48 and a communication path (e.g., serial, parallel, IR, RC, 10bT, etc.). The external systems 50 may include a gaming network, other gaming machines, a gaming server, communications hardware, or a variety of other interfaced systems or components. Although the I/O circuits 46, 48 may be shown as a single block, it should be appreciated that each of the I/O circuits 46, 48 may include a number of different types of I/O circuits.
Controller 34, as used herein, comprises any combination of hardware, software, and/or firmware that may be disposed or resident inside and/or outside of the gaming machine 10 that may communicate with and/or control the transfer of data between the gaming machine 10 and a bus, another computer, processor, or device and/or a service and/or a network. The controller 34 may comprise one or more controllers or processors. In
The gaming machines 10, 110 may communicate with external systems 50 (in a wired or wireless manner) such that each machine operates as a “thin client,” having relatively less functionality, a “thick client,” having relatively more functionality, or through any range of functionality therebetween (e.g., a “rich client”). As a generally “thin client,” the gaming machine may operate primarily as a display device to display the results of gaming outcomes processed externally, for example, on a server as part of the external systems 50. In this “thin client” configuration, the server executes game code and determines game outcomes (e.g., with a random number generator), while the controller 34 on board the gaming machine processes display information to be displayed on the display(s) of the machine. In an alternative “rich client” configuration, the server determines game outcomes, while the controller 34 on board the gaming machine executes game code and processes display information to be displayed on the display(s) of the machines. In yet another alternative “thick client” configuration, the controller 34 on board the gaming machine 110 executes game code, determines game outcomes, and processes display information to be displayed on the display(s) of the machine. Numerous alternative configurations are possible such that the aforementioned and other functions may be performed onboard or external to the gaming machine as may be necessary for particular applications. It should be understood that the gaming machines 10, 110 may take on a wide variety of forms such as a free standing machine, a portable or handheld device primarily used for gaming, a mobile telecommunications device such as a mobile telephone or personal daily assistant (PDA), a counter top or bar top gaming machine, or other personal electronic device such as a portable television, MP3 player, entertainment device, etc.
As mentioned above, in existing gaming machines, the base games and the bonus games, including progressive jackpots and other communal games, are part of a single integrated gaming package. As a result, players, casino operators, and/or gaming machine manufacturers have few options in terms of being able to choose a different bonus game to play with a particular base game (and vice versa) for a given gaming machine. Embodiments of the invention provide a gaming machine system and method in which the base games and/or the bonus games may be selected for gameplay independently of one another. This modular approach allows a player, casino operator, and/or gaming machine maker (hereinafter “user”) to mix and match base games and bonus games as needed via an appropriate user interface. In some embodiments, the user may also select different features to employ with each bonus and/or base game. Such a mix and match gaming arrangement allows different users to customize each gaming machine with base games and/or bonus games according to their particular preferences.
The above gaming arrangement is graphically illustrated in
In operation, instead of the integrated base game/bonus game approach used in existing gaming machines, each base game package 54a-c and each bonus game package 56a-c may be separately selected and downloaded. That is, the selection and download of the base game packages 54a-c may be independent of the selection and download of the bonus game packages 56a-c, and vice versa. Such a gaming arrangement provides users with the flexibility to mix and match base games and bonus games in a single gaming machine 10, thereby creating a more desirable combination. The timing of the download may be in real time (e.g., during gameplay), or one or more base game packages 54a-c and/or bonus game packages 56a-c may be downloaded ahead of time and stored on the gaming machine 10 for subsequent gameplay. Note that although the gaming machine 10 shown here is a free standing gaming machine, embodiments of the invention are fully applicable to handheld, bartop, and workstation models as well.
The base game and bonus game storage units 54 and 56 may be any suitable storage devices known to those having ordinary skill in the art, including one or more computer-readable storage media. Examples of such computer-readable storage media include a magnetic disk and an optical disk on which the base game and bonus game packages 54a-c and 56a-c may reside. The base game and bonus game packages 54a-c and 56a-c may then be stored as computer-readable instructions on the base game and bonus game storage units 54 and 56, respectively.
The portal 58 serves essentially as an electronic gateway between the gaming machines 10a-c and the base game and bonus game storage units 54 and 56 to control access to, security for, and transfer of the base game and bonus game packages 54a-c and 56a-c from their respective storage units to the gaming machines 10a-c. In one embodiment, the portal 58 may be any suitable server known to those having ordinary skill in the art, including a web server capable of communicating with the gaming machines 10a-c and the control systems 62 over the Internet. And although only one portal 58 is shown, those having ordinary skill in the art will understand that multiple portals 58 may be deployed on the network 60 as needed.
Similarly, the network 60 may be any suitable network known to those having ordinary skill in the art, including a wide area network (WAN) providing communication between a plurality of casinos, one or more local area networks (LAN) providing intra-casino communication, and the like. The communication over the network 60 may be transmitted via wired and/or wireless connections, and may employ any suitable communication technology, including Bluetooth, 802.11, Ethernet, public switched telephone networks, SONET, and the like.
The gaming machines 10a-c may likewise take any suitable form, including the free standing models 10 and the handheld, bartop, and workstation models 110 discussed above with respect to
The one or more control systems 62, as mentioned above, allow a casino operator and/or gaming machine manufacturer to access the portal 58 over the network 60. In contrast, players typically access the portal 58 through the gaming machines 10a-c. The casino operator and/or gaming machine manufacturer may then use the control systems 62 to select and download, either in real time or beforehand, certain ones of the base game and bonus game packages 54a-c and 56a-c for specific gaming machines 10a-c. The control systems 62 also allow the casino operator and/or gaming machine manufacturer to track which base game and/or bonus game packages 54a-c and 56a-c are being downloaded by players and, if desired, configure or otherwise established certain predetermined rules regarding which base game packages 54a-c and bonus game packages 56a-c may be combined together. The casino operator and/or gaming machine manufacturer may also set up certain default base game and/or bonus game packages 54a-c and 56a-c for certain players based on their predefined preferences and/or selection history.
To execute the base game and bonus game packages 54a-c and 56a-c, a game engine 64a, 64b, and 64c is provided on each gaming machine 10a-c. The game engine 64a-c, in some embodiments, is not in and of itself a complete base game or bonus game, but is instead a shell or platform that may be used by the controller 34 (
As for the base game and bonus game packages 54a-c and 56a-c themselves, in some embodiments, these packages may contain the instruction sets (i.e., computer-executable codes, script commands, game logic, math configuration files, etc.) for telling the game engine 64a-c how to reproduce the base games and bonus games. For example, the base game packages 54a-c may contain instructions regarding the number of reels in the base game, symbol placements, bonus game triggers, and the like. Similarly, the bonus game packages 56a-c may contain instructions regarding the type of bonus game (e.g., player-selection game, free-spins game, progressive jackpot eligibility bonus game, etc.), or the configuration of the bonus game (e.g., array size, game-ending mechanism, etc.). Alternatively, the base game and bonus game packages 54a-c and 56a-c may simply contain the math configuration files, with the rest of the components (e.g., game logic, etc.) residing in the game engine 64a-c. Or there may be some intermediate combination of the above two approaches.
Other wagering game components besides the instruction sets may also be contained in the base game packages 54a-c and bonus game packages 56a-c. For example, most wagering games use some type audio content, visual content, or other theme related aspects. Examples of such audio and visual contents may include background art/graphics, symbol fonts, sounds/music, characters/avatars, and the like. In accordance with embodiments of the invention, these aspects of the base game and the bonus game may also be contained in the base game packages 54a-c and bonus game packages 56a-c along with any instruction sets. Alternatively, the audio and/or visual content may be stored locally on the individual gaming machines 10a-c. Thus, for example, the same base game package 54a-c reproduced on two different gaming machines 10a-c may have two different themes, depending on the particular setup of the gaming system.
In addition to selecting the base game packages 54a-c and bonus game packages 56a-c, in some embodiments, users may also select various game features to accompany the base game packages 54a-c and bonus game packages 56a-c. Such game features are typically provided as enhancements to the base games and bonus games and may include, for example, various bonus game triggering mechanisms (e.g., bonus symbols, secondary indicia, etc.), payout multipliers, payout frequency, scatter pays, mystery pays, and the like. Other game features may include, for example, different game-ending mechanisms (e.g., number of spins, number of picks, etc.), progressive jackpot levels (e.g., local versus wide area), and the like. Alternatively, one or more game features may be an integral part of the base game and/or bonus game so that they are downloaded automatically by default with each base game package 54a-c and bonus game package 56a-c.
a and 5b illustrate an exemplary base game package 54a (
In some embodiments, depending on the particular base game package 54a and bonus game package and 56a selected, one or more of the base game features 66a-c and/or bonus game features 68a-c may not be available for selection by the players, casino operators, and/or gaming machine manufacturers due to compatibility reasons. In other embodiments, one or more of the base game features 66a-c and bonus game features 68a-c may be displayed (via a user interface) to the players, casino operators, and/or gaming machine manufacturers more prominently, for example, as a result of certain predefined preferences and/or previous selections tracked over time.
Throughout
In some embodiments, the expected values may be designed to be uniform across each selectable type of component. Thus, every base game may be designed to have the same expected value, every bonus game to have the same expected value, every base game feature to have the same expected value, and every bonus game feature to have the same expected value. In other embodiments, the expected values for one or more of the base games, bonus games, and/or various features may be undefined until they are downloaded to the gaming machines 10a-c. The expected values for one or more of these base games, bonus games, and/or various features therefor may thereafter be set based on the expected values of the gaming machines 10a-c and the expected values of the other downloaded base games, bonus games, and/or various features therefor. In still other embodiments, however, there may be little or no correlation between the various expected values, depending on the particular application. Therefore, while still falling within their individual acceptable ranges, one or more base games, bonus games, and/or their respective game features may have varied and disparate expected values.
Using varied and disparate expected values can provide more variety and therefore more excitement and enjoyment for players. However, since the base game is independently selectable from the bonus game, it is possible to choose a base game-bonus game combination where the overall expected value is outside the allowed range (e.g., 85-95 percent). This may result in lost revenue to casino operators and gaming machine manufacturers if the overall expected value exceeds the allowed range. On the other hand, falling below the allowed range may cause players to become disenchanted with the gaming machines and may also violate regulatory requirements in some jurisdictions.
Referring now to
Sometimes it may be desirable to allow a certain base game-bonus game combination to proceed even when the overall expected value exceeds the targeted range. A casino operator and/or gaming machine manufacturer may wish to do this, for example, as a way to reward particularly active players based on their wagering history or as part of a special event (e.g., a slot machine tournament). In that case, the expected value regulator 70 may provide an option for the casino operator and/or gaming machine manufacturer to temporarily override any prohibition and allow the prohibited combination to proceed for a predetermined period of time (e.g., half an hour, etc.).
Sometimes the choice of which base game packages 54a-c may be combined with which bonus game packages 56a-c may be set by the game designers. In those instances, the expected value regulator 70 may identify prohibited combinations by referring, for example, to one or more lookup tables instead of evaluating the expected value of each combination. In addition, for certain instances where the overall expected value is close, but does not quite satisfy the targeted expected value or just falls below the allowed range, the expected value regulator 70 may randomly award a mystery prize to the player to compensate for the difference in the actual and targeted expected values.
In some embodiments, it may be possible to eliminate the above expected-value problem altogether by requiring each base game package 54a-c and bonus game package 56a-c, as well as their respective game features 66a-c and 68a-c, to be independently funded. Thus, for example, at some point before or during the base game, or when the bonus game is triggered, the player may be asked to place a supplemental wager in order to play the bonus game and/or to activate a certain game feature. The additional wager may then be used to fund the bonus game and/or game feature while the initial wager may be reserved for the base game. In this way, players may choose (and pay for) any combination of base games and bonus games a desire, and may activate any compatible game features they please.
