BACKGROUND
Wagering game machine makers continually provide new and entertaining games. One way of increasing entertainment value associated with casino-style wagering games (e.g., video slots, video poker, video blackjack, and the like) includes offering a variety of base games and bonus events.
However, despite the variety of base games and bonus events, players often lose interest in repetitive wagering gaming content. In order to maintain player interest, wagering game machine makers frequently update wagering game content with new game themes, game settings, bonus events, game software, and other electronic data. Consequently, there is a need to provide for seamless integration of base wagering games, bonus wager garrles, game themes, game settings, game software, and other electronic data to ensure an attractive gaming experience.

CPU 126 may be realized using various forms of a processor and/or a controller. Main memory 128 may be coupled through a bus 122 or directly to CPU 126 using a communication medium such as a memory bus. A bus may include command control lines, data lines, address lines, other communication lines, or combinations thereof.
From a player's perspective, a wagering game is a game whose player participation is initiated with the player placing a wager in some manner, in which the occurrence of an event having some probability of happening results in an award to the player tied in some manner to the player's wager. In various wagering games, the reward may be tied to the player's wager merely by placing the wager. A wagering game may include a game in which a wager is made in a different game, but an award is a possible outcome from the wagering game. A
bonus wagering game is such a wagering game whose play is correlated to a base wagering game. Each wagering game, whether a base game or bonus game, may include the instrumentality to control or regulate the play of the wagering game, including the flow of signals and data within one or more devices. Such instrumentality may include hardware, software, firmware, or various combinations thereof A wagering game may be realized using one or more units or modules that manage the play of the wagering game. In an embodiment, such units or modules may be realized using one or more components of wagering game machine architecture 100 or similar architecture.
Wagering game presentation unit 132 may be an independent unit in wagering game machine 106. Wagering game presentation unit 132 may include a processor and/or controller, memory, or combinations thereof. An independent wagering game presentation unit 132 may operate with CPU 126 and/or main memory via bus 122 or via a direct connection. Wagering game presentation unit 132 may be realized as integral to main memory 128. Wagering game presentation unit 132 may be realized having components in CPU 126 and in main memory 128.

The wagering game architecture includes a hardware platform 202, a boot program 204, an operating system 206, and a game framework 208 that includes one or more wagering game software components 210. In various embodiments, hardware platform 202 may include a thin-client, thick-client, or some intermediate derivation. A thin client may be a client in client-server architecture networks which has little or no application logic, such that it depends primarily on a central server for processing activities.
A thin client may use a small boot image to connect to a network and start up a dedicated web browser. A thin client may load its operating system (OS) and software from a server. A thin client may be a client in which no data is stored and relatively little processing occurs on the client machine. Thick clients may be full-featured computers that are connected to a network. A thick client, which may also be referenced as a heavy client, may be configured as functional machines, whether configured as a standalone machine or connected to a network, unlike typical thin clients that may lack hard drives and other features.
Hardware platform 202 may also be configured to provide a virtual client. Boot program 204 may include a basic input/output system (BIOS) or other initialization program that works in conjunction with operation system to provide a software interface to hardware platform 202. Game framework 208 may include standardized game software components either independent or in combination with specialized or customized game software components that are designed for a particular wagering game. In an embodiment, wagering game software components 210 may include software operative in connection with hardware platform 202 and operating system 206 to p'resent wagering games, in whole or part, such as video poker, video black jack, video slots, video lottery, video role playing games having wagering content, etc. In an embodiment, software components 210 may include software operative to accept a wager from a player. According to an embodiment, game software components 210 include one or more components to control adjustment of a feature of a wagering game and/or a feature of another wagering game to fix a parameter of the combination of the wagering games correlated to a relationship between a parameter of each of the wagering games. According to an embodiment, one or more of the software components 210 may be provided as part of the operating system 206 or other software used in the wagering game system 200 (e.g., libraries, daemons, common services, etc.).
Figure 3 illustrates a block diagram of an embodiment of a porta1310 to couple together two wagering games. Porta1310 may provide instrumentality to control the adjustment of features in a first wagering game 320, in a second wagering game 330, or in both the first and second wagering games 320, 330.
First wagering game 320 and/or second wagering game 330 may be played in one or more wagering game machines, examples of which are described herein.
Porta1310 allows attainment of an equilibrium between first wagering game 320 and second wagering game 330. The adjustment of features may be based on a fixed parameter for the combination of the two games. The fixed parameter may be correlated to parameters of first and second wagering games 320, 330. For example, where first wagering game 320 and second wagering game 330 are wagering games that have payout amounts in individual play typically known by a player, porta1310 may allow these typical payout amounts to occur in each of the two wagering games when played in combination by adjusting a frequency of the payouts such that the average payout of the combination of the two wagering games has a predetermined value. In an embodiment, portal 310 may provide for the expected value of first wager game 320 and the expected value of second wagering game 330 to be the same in combination play as in individual play with adjustment of other features or parameters to substantially match a fixed parameter for the combined play. An expected value (EV) is the average number of credits a pay or feature pays on average over the long run. It may be calculated as a percentage of the overall payback of a given game and may be provided by multiplying the average pay of the feature times its probability of occurring. First wagering game 320 and second wagering game 330 may be selected by a player concurrently from a presentation of wagering games on a screen in a wagering game machine. Second wagering game 330 may be selected by a player from a presentation of wagering games in a wagering game machine during play of first wagering game 320. Second wagering game 330 may be selected by a player from a presentation of wagering games in a wagering game machine during the initiation of play in first wagering game 320.
Figure 4 illustrates a block diagram of an embodiment of a porta1410 to couple together a base wagering game 420 and a bonus wagering game 430.

Porta1410 may provide instrumentality to control the adjustment of features in base wagering game 420, in bonus wagering game 430, or in both base wagering game 420 and bonus wagering game 430. In an embodiment, porta1410 allows any bonus wagering game in a set of bonus wagering games to be played with base wagering game 420. Base wagering game 420 and bonus wagering game 430 may be played in one or more wagering game machines, examples of which are described herein. Porta1410 allows a sort of equalization between base wagering game 420 and bonus wagering game 430. The adjustment of features may be based on a fixed parameter for the combination of base wagering game 420 and bonus wagering game 430. The fixed parameter may be correlated to parameters of base wagering game 420 and bonus wagering game 430. For example, where base wagering game 420 and bonus wagering game 430 are wagering games that have payout amounts in individual play typically known by a player, porta1410 may allow these typical payout amounts to occur in each of base wagering game 420 and bonus wagering game 430 when played together by adjusting a frequency of the payout such that the average payout of the combination of base wagering game 420 and bonus wagering game 430 has a predetermined value. In an embodiment, porta1410 may provide for the expected value of base wagering game 420 and the expected value of bonus wagering game 430 to be the same in combination play as in individual play with adjustment of other features or parameters to substantially match a fixed parameter for the combined play. Bonus wagering game 430 may be selected by a player from a presentation of bonus wagering games on a screen in a wagering game machine. Bonus wagering game 430 may be selected by a player from a presentation of bonus wagering games in a wagering game machine during initial play and/or subsequent play of base wagering game 420.
Figure 5 illustrates a block diagram of an embodiment of a portal 510 to couple a base wagering game 520 with multiple bonus wagering games 530-1 ... 530-N. Porta1510 may provide instrumentality to control the adjustment of features in base wagering game 520, in one or more of bonus wagering games 530-1 ... 530-N, or in base wagering game 520 and one or more of bonus wagering games 530-1 ... 530-N. Base wagering game 520 and bonus wagering games 530-1 ... 530-N may be played in one or more wagering game machines, examples of which are described herein. Porta1510 provides for acquiring a balance between base wagering game 520 and bonus wagering games 530-1 ... 530-N. The adjustment of features may be based on a fixed parameter for the combination of base wagering game 520 and bonus wagering games 530-1 ... 530-N, where the fixed parameter may be correlated to parameters of base wagering game 520 and bonus wagering games 530-1 ...
530-N. For example, where base wagering game 520 and bonus wagering games 530-1 ... 530-N have payout amounts in individual play typically known by a player, portal 510 may allow these typical payout amounts to occur in each of base wagering game 520 and bonus wagering games 530-1 ... 530-N when played together by adjusting a frequency of the payout such that the average payout of the combination of base wagering game 520 and bonus wagering games 530-1 ... 530-N has a predetermined value. In an embodiment, portal 510 may provide for the expected value of base wagering game 520 and the expected value of each of bonus wagering games 530-1 ... 530-N to be the same in combination play as in individual play with adjustment of other features or parameters to substantially match a fixed parameter for the combined play.
Bonus wagering games 530-1 ... 530-N may be selected by a player from a presentation of bonus wagering games on a screen in a wagering game machine.
Bonus wagering games 530-1 ... 530-N may be selected by a player from a presentation of bonus wagering games in a wagering game machine during initial play and/or subsequent play of base wagering game 520. The features/parameters of bonus wagering games may reside in a data library at one or more locations in a wagering game network. Accessibility by a portal to bonus wagering games and/or their features/parameters in the data library may be may be dynamically set, that is, changed, modified, controlled or otherwise regulated in real-time.
In various embodiments, a portal may be triggered in a wagering game by the occurrence of an event or selection of the portal as part of the game play.
The triggering event may be the occurrence of symbols on one or more pay lines or the occurrence of symbols at random locations on the playing screen of the wagering game machine. A triggering event in a base wagering game may initiate access to bonus wagering games. In an embodiment, the triggering event provides a means for player selection of one or more bonus games. The bonus wagering games may be displayed on the playing screen. Alternatively, various options may be displayed such that the selection of the options generates a bonus game or a set of bonus games. Such options may include, but are not limited to, bonus game volatility, bonus game payout, selection of a bonus game with an associated extra bet, and other options. Volatility is a measure of how a player experiences the pay back of a particular game. Some games pay out more often in smaller amounts. This is known as a low volatility game. Some games pay out less often in larger amounts. This is known as a high volatility game.
Such selection may be provided through activation of a touch screen, activation of one or more buttons on a wagering game device or system, clicking of a computer-like mouse, activation of a screen display using electromagnetic stimulus wirelessly generated, or combinations of various selection actions. The data provided to the portal may be generated as information calculated or derived in response to a selection event. Upon identification of one or more bonus wagering games to be played with the base wagering game, a portal may operate as discussed above with respect to portals 310, 410, and 510 or in a variation of these portals.
In various embodiments, a portal may use various features/parameters to provide a balance between a base wagering game and one or more bonus wagering games. A portal may maintain one or more features/parameters at substantially fixed values in operation as a conduit between a base wagering game and one or more bonus wagering games. Such features/parameters may include, but are not limited to, the average total payout for the combined play or the expected value of each wagering game involved in the combined play. To maintain an equilibrium in the combined play, a portal may adjust a frequency at which a player may receive a winning event. A frequency adjustment may be provided in adjusting the game volatilities by assigning the probabilities in the underlying game control according to the player selected options. Weighted tables may be used to provide the probabilities associated with the player selection options to meet the balancing constraint used by the portal. An event frequency may be adjusted with the inclusion of a number of free spins, a number of game ending events, time length of the bonus game, or combinations thereof. A game ending event or an event for ending a portion of a game may be realized by the occurrence of a symbol as the result of a player activated spin or other player activated event.

In an embodiment, a portal may provide for the combined play of two or more wagering games by control of parameters in these games such that the game play presented to a player on a screen maintains the game play presentation as if the wagering games were played individually. The portal may provide such control by generating a request for an additional wager to transition from one game to the other game. The additional wager may be used to adjust for differences in expected value of the wagering games being played to maintain a substantially fixed expected value for the combined play. In various embodiments, transitions between games may include accumulation of credits to be played at a future time, where the portal controls the storage of information that correlates a player to an accumulated amount of credits and one or more wagering games. Credits may be scaled to a monetary unit.
In an embodiment, a portal and associated wagering games may be realized within a wagering network. Use of a portal for a wagering game machine may occur using instrumentality that is distributed among devices or systems that can communicate with the wagering game machine from which activation of the portal occurred. In addition to various embodiments with a portal used in server based gaming (SBG), such portals may be configured on individual wagering game machines. In an embodiment, content used by a portal may be readily movable about a network. In an embodiment, portal content, including such items as identification of wagering games that may be coupled by a portal, may be controlled at a manufacturing stage. In an embodiment, portal content, including such items as identification of wagering games that may be coupled by a portal, may be controlled at one or more casinos. In an embodiment, portal content, including such items as identification of wagering games that may be coupled by a portal, may be controlled at a network control location.

Example Operations Figure 6 illustrates a flow diagram of features of an embodiment of a method for a portal to control adjustment of features to couple together wagering games. At 610, a first wagering game is identified. An identification event may include receiving data or a signal regarding features/parameters of the first wagering game at a portal. The first wagering game may be identified by initiating game play in a specific wagering game machine, by selecting the first wagering game from multiple wagering games available, or a combination thereof. Such selection may be provided through activation of a touch screen, activation of one or more buttons on a wagering game device or system, clicking of a computer-like mouse, activation of a screen display using electromagnetic stimulus wirelessly generated, or combinations of various selection actions.
The data provided to the portal may be generated as information calculated or derived in response to a selection event. A set of features/parameters may be associated with the first wagering game.
At 620, a second wagering game is identified. The second wagering game may be selected from a list or presentation of multiple wagering games provided in the first wagering game. The second wagering game may be selected as the result of a player's selection of options presented in the first wagering game. Such options may include, but are not limited to, bonus game volatility, bonus game payout, selection of a bonus game with an associated extra bet, and other options. Such selection may be provided through activation of a touch screen, activation of one or more buttons on a wagering game device or system, clicking of a computer-like mouse, activation of a screen display using electromagnetic stimulus wirelessly generated, or combinations of various selection actions. The second wagering game may be a bonus wagering game in a set of bonus wagering games. Multiple bonus games may be combined with a base wagering game by the portal. The second wagering game may be another wagering game with an additional wager correlated to combining play with the first wagering game. A set of features/parameters may be associated with the second wagering game.
At 630, features of the first wagering game, features of the second wagering game, or features of the first wagering game and features of the second wagering game may be adjusted to fix a parameter of the combination of the first wagering game and the second wagering game. Such a parameter may be correlated to a relationship between parameters of the first and second wagering games. The portal may adjust various features to maintain, at a substantially fixed value, an expected value in each of the wagering games coupled by the portal. The portal may adjust various features to maintain, at a substantially fixed value, an average total payout of the combination of wagering games coupled by the portal. The portal may adjust the frequency at which a winning event occurs in the combination of games. The portal may adjust the frequency at which a winning event occurs in one or more of the wagering games in the play combination. The portal may adjust the inclusion of a number of free spins, a number of game ending events, time length of the bonus game, or combinations thereof in one or more wagering games in the play combination.
Example Wagering Game Network Figure 7 shows a block diagram. illustrating an embodiment of a wagering game network 700, according to example embodiments of the invention. Wagering game network 700 may include multiple casinos 712 connected to a communications network 714.

The wired and wireless communication links 708, 710 may employ any suitable connection technology, such as Bluetooth, 802.11, Ethernet, public switched telephone networks, SONET, etc. In an embodiment, the wagering game server 706 may serve wagering games and/or distribute content to devices located in other casinos 712 or at other locations on communications network 714.

Wagering game machines 702 and wagering game server 706 may include hardware and machine-readable media including instructions for performing embodiments of the operations described herein.
Wagering game machines 702 described herein may take any suitable form, such as floor standing models, handheld mobile units, bartop models, workstation-type console models, etc. Further, wagering game machines 702 may be primarily dedicated for use in conducting wagering games, or may include non-dedicated devices, such as mobile phones, personal digital assistants, personal computers, etc. In an embodiment, the wagering game network 700 may include other network devices, such as accounting servers, wide area progressive servers, player tracking servers, and/or other devices suitable for use in connection with embodiments of the invention.
In various embodiments, wagering game machines 702 and wagering game servers 706 work together such that wagering game machine 702 may be operated as a thin, thick, or intermediate client. For example, one or more elements of game play may be controlled by wagering game machine 702 (client) or the wagering game server 706 (server). Game play elements may include executable game code, lookup tables, configuration files, game outcome, audio or visual representations of the game, game assets or the like. In a thin-client example, wagering game server 706 may perform functions such as determining game outcome or managing assets, while wagering game machine 702 may be used merely to present the graphical representation of such outcome or asset modification to the user (e.g., player). In a thick-client example, game outcome may be determined locally (e.g., at wagering game machine 702) and then communicated to wagering game server 706 for recording or managing a player's account.
Similarly, functionality not directly related to game play may be controlled by wagering game machine 702 (client) or the wagering game server 706 (server) in embodiments. For example, power conservation controls that manage a display screen's light intensity may be managed centrally (e.g., by wagering game server 706) or locally (e.g., by wagering game machine 702).
Other functionality not directly related to game play may include presentation of advertising, software or firmware updates, system quality or security checks, etc.
Example Wireless Environment In some embodiments, wireless access point 704 and wagering game machines 702 may communicate using orthogonal frequency division multiplexed (OFDM) communication signals over a multicarrier communication channel. The multicarrier communication channel may be within a predetermined frequency spectrum and may include multiple orthogonal subcarriers. In some embodiments, the multicarrier signals may be defined by closely spaced OFDM subcarriers. Each subcarrier may have a null at substantially a center frequency of the other subcarriers and/or each subcarrier may have an integer number of cycles within a symbol period. In some embodiments, wireless access point 704 and wagering game machines 702 may communicate in accordance with a broadband multiple access technique, such as orthogonal frequency division multiple access (OFDMA).

Player-accessible value input device 918 may include, for example, a slot located on the front, side, or top of housing 912 configured to receive credit from a stored-value card (e.g., casino card, smart card, debit card, credit card, etc.) inserted by a player. The player-accessible value input device 918 may also include 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 918 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 may transfer money to wagering game machine 900.
Still other player-accessible value input devices 918 may make use of touch keys 930 on the touch-screen display (e.g., primary display 914 and/or secondary display 916) or player input devices 924. In an embodiment, upon entry of player identification information and 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 an optional security feature, wagering game machine 900 may be configured to permit a player to only access an account the player has specifically set up for wagering game machine 900. Other conventional security features may also be utilized, for example, to 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 wagering game machine 900.
Player-accessible value input device 918 may itself include 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 918. In an embodiment where player-accessible value input device 918 includes a biometric player information reader, transactions may be authorized by a biometric reading from the biometric device, which may include multiple biometric readings. Such transactions may include, for example, an input of value to wagering game machine 900, a transfer of value from a player account or spurce to an account associated with wagering game machine 900, or the execution of another transaction.
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, player-accessible value input device 918 may include a biometric player information reader that may use a confirmatory entry from another biometric player information reader 952, 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. Any two independent sources of identity, one of which is secure or personal to the player (e.g., biometric readings, PIN number, password, etc.) may be utilized to provide enhanced security prior to the electronic transfer of any funds. Value input device 918 may be provided remotely from wagering game machine 900.
Player input device 924 may include multiple push buttons on a button panel for operating wagering game machine 900. In addition, or alternatively, player input device 924 may include a touch screen mounted to a primary display 914 and/or secondary display 916. The touch screen may be matched to a display screen having one or more selectable touch keys 930 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 at an appropriate touch key 930 or by pressing an appropriate push button on the button panel. Touch keys 930 may be used to implement the same functions as push buttons. Alternatively, push buttons 932 may provide inputs for operating one part of the game, while touch keys 930 may allow for input needed for another part of the game. The various components of wagering game machine 900 may be connected directly to, or contained within, housing 912 or may be located outside housing 912 and connected to housing 912 via a variety of wired (tethered) or wireless connection methods. Thus, wagering game machine 900 may be configured as a single unit or as multiple interconnected (e.g., wireless connections) parts, which may be arranged to suit a player's preferences.
The operation of the basic wagering game on wagering game machine 900 may be displayed to the player on primary display 914. Primary display 914 may also display one or more bonus games associated with the basic wagering game. Primary display 914 may take the form of a high resolution LCD, a plasma display, an LED, or any other type of display suitable for use in wagering game machine 900. The size of primary display 914 may vary from, for example, about a 2-3" display to a 15" or 17" display. In some embodiments, primary display 914 is a 7"-10" display. However, primary display 914 is not limited to the above sizes. In an embodiment, 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 various embodiments, primary display 914 and/or secondary display 916 may have a 16:9 aspect ratio or other aspect ratio (e.g., 4:3). Primary display 914 and/or secondary display 916 may also each have different resolutions, different color schemes, and different aspect ratios.
As with free standing embodiments, a player begins play of the basic wagering game on wagering game machine 900 by making a wager (e.g., via value input device 918 or an assignment of credits stored on the handheld gaming machine via touch screen keys 930, player input device 924, or buttons 932) on wagering game machine 900. In various embodiments, a wagering game may include multiple symbols arranged in an array and may include at least one pay line 928 that indicates one or more outcomes of the wagering game. Pay line 928 may be realized as multiple pay lines. Pay line 928 may be horizontal lines or may be arranged in a variety of ways, including diagonal lines, vertical lines, or zigzag lines. Such outcomes may be randomly selected in response to the wagering input by the player. One or more randomly selected outcomes may be a start-bonus outcome, which may include any variations of symbols or symbol combinations triggering a bonus game.
In various embodiments, player-accessible value input device 918 of wagering game machine 900 may double as a player information reader 952 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
