Disclosed are methods, apparatus, and systems implementing techniques for using a central determination system with multi-play gaming machines having sub-games and with gaming machines having a base game and a bonus game. A seed value is provided for each of the games (i.e., each of the sub-games or the base game and the bonus game). This ensures that all possible game outcomes may be displayed for each of the games.

Multi-play central determination system

Various embodiments of the disclosed gaming device include a housing which supports a plurality of mechanical reels and a plurality of stop input devices which are configured to provide a Pachisuro-style slot game. Each of the plurality of reels is associated with a different one of the plurality of stop input devices. Each stop input device enables a player to stop the respective reel when the reel is spinning by activating the stop input device. Each reel includes a plurality of stop positions and each stop position includes a symbol. The gaming device also includes a processor and a memory device. For each reel, the processor randomly determines the stop position at which the reel ultimately stops based on a virtual map stored in the memory device for an initiating stop position of that reel which is selected by the player's activation of the stop input device for that reel.

Novel methods, devices and systems are described for mapping a variety of Class III game outcomes to sets of bingo patterns. Each game theme may have a different entertaining display, based upon a corresponding Class III game. Preferably, each game theme will offer game play and paytable percentages closely matching those of the original Class III game. Some implementations provide a system wherein separate pay tables and bingo pools are formed according to the number of paylines played on slot-type game themes and/or the number of hands played on poker game themes. In some such implementations, players will be limited to predetermined numbers of lines (or hands) played, e.g., only 1, 3, 5 or 9 lines. In alternative implementations, a player's options regarding the number of lines played will depend, at least in part, on how many other players are playing any given number of lines on a slot game. Preferred implementations provide a range of payback percentages for each of the predetermined numbers of lines (or hands) played.

Bingo gaming machine capable of selecting different bingo pools

The gaming system and method disclosed herein provides a bingo game wherein a single bingo pattern is associated with a plurality of outcomes. In one such embodiment, a first bingo pattern is associated with a static outcome, such as an award of a designated value, and a second bingo pattern is associated with an open-ended outcome, such as a progressive award. If a bingo pattern associated with a progressive award is covered, the disclosed gaming system and method causes the bingo game to display, a symbol combination associated with the progressive award. In one embodiment, the disclosed gaming system and method selects the symbol combination from a plurality of symbol combinations associated with the progressive award.

Bingo gaming system and method for providing multiple outcomes from single bingo pattern

A gaming system which provides the player a plurality of playing cards to form an initial primary card hand and also displays one or more other card hands. The player selects one or more of the initially dealt cards in the primary card hand to hold or to discard. The held cards are also held in one, more or each of the other simultaneously displayed hands. The gaming device evaluates the held cards and determines which card game outcomes are possible based on the held cards and the remaining cards in the deck. The gaming device utilizes a stored table of different distributions of card game outcomes which would result in each payout amount and a table regarding which card game outcomes are possible based on the player's held cards to determine a distribution of outcomes that provides a total payout equal to the payout of the predetermined game outcome.

The gaming system and method disclosed herein provides a bingo game wherein a single bingo pattern is associated with a plurality of outcomes. In one such embodiment, a first bingo pattern is associated with a static outcome, such as an award of a designated value, and a second bingo pattern is associated with an open-ended outcome, such as a progressive award. If a bingo pattern associated with a progressive award is covered, the disclosed gaming system and method causes the bingo game to display a symbol combination associated with the progressive award. In one embodiment, the disclosed gaming system and method selects the symbol combination from a plurality of symbol combinations associated with the progressive award.

Novel methods, devices and systems are described for mapping a variety of Class III game outcomes to a common set of bingo patterns. Each game theme may have a different entertaining display, based upon a corresponding Class III game. Preferably, each game theme will offer game play and paytable percentages closely matching those of the original Class III game. Some implementations provide a system wherein electronic gaming machines presenting entertaining displays of various Class III game themes are linked to a single bingo server. By linking many participating electronic gaming machines to a single server, some implementations of the invention allow all of the progressive contributions to be pooled into one large progressive jackpot, thereby making the game more attractive to players.

Novel methods, devices and systems are described for mapping pay amounts for a variety of Class III game themes to a common set of bingo pay amounts. Each Class III game theme may cause a different type of entertaining display on a gaming machine when bingo is played, based upon a corresponding Class III game. Preferably, each Class III game theme will offer game play and paytable percentages closely matching those of the original Class III game. Some implementations allow flexibility in matching the probabilities of bingo outcomes and Class III game outcomes by mapping ranges of Class III pay amounts to a single bingo pay amount. Some implementations provide a system wherein electronic gaming machines presenting entertaining displays of various Class III game themes are linked to a single bingo server.

Bingo system with discrete payout categories

A gaming system which provides the player a plurality of playing cards to form an initial primary poker hand and also displays one or more other poker hands. The player selects one or more of the initially dealt cards in the primary poker hand to hold or to discard. The held cards are also held in one, more or each of the other simultaneously displayed hands. The gaming device evaluates the held cards and determines which poker game outcomes are possible based on the held cards and the remaining cards in the deck. The gaming device utilizes a stored table of different distributions of poker game outcomes which would result in each payout amount and a table regarding which poker game outcomes are possible based on the player's held cards to determine a distribution of outcomes that provides a total payout equal to the payout of the predetermined game outcome.

Methods, devices and systems are described for mapping a variety of Class III game outcomes to a common set of bingo patterns. Each game theme may have a different entertaining display, based upon a corresponding Class III game. Preferably, each game theme will offer game play and paytable percentages closely matching those of the original Class III game. In order to more closely match Class III game play, some implementations provide a system wherein the hit frequency of a bingo game will be modulated according to Class III game options selected by a player. The options may be, for example, paylines of a simulated slot game. In preferred implementations, this modulation is accomplished by varying the number of bingo cards provided in the underlying bingo game according to the options (e.g., the number of paylines) selected.
