Embodiments of a gaming method and gaming controller as described are adapted to determine a minimum prize value for a current game outcome based on a previous game outcome and set the prize to be awarded for the current game outcome to the minimum prize value if a provisional prize value determined based on the current game outcome is less than the determined minimum prize value. Embodiments may be applied to any type of game, such as a spinning reel game, poker, keno, bingo, pinball, dice and the like implemented.
In a first form, a stand alone gaming machine is provided wherein all or most components required for implementing the game are present in a player operable gaming machine.
In a second form, a distributed architecture is provided wherein some of the components required for implementing the game are present in a player operable gaming machine and some of the components required for implementing the game are located remotely relative to the gaming machine. For example, a “thick client” architecture may be used wherein part of the game is executed on a player operable gaming machine and part of the game is executed remotely, such as by a gaming server; or a “thin client” architecture may be used wherein most of the game is executed remotely such as by a gaming server and a player operable gaming machine is used only to display audible and/or visible gaming information to the player and receive gaming inputs from the player.
However, it will be understood that other arrangements are envisaged. For example, an architecture may be provided wherein a gaming machine is networked to a gaming server and the respective functions of the gaming machine and the gaming server are selectively modifiable. For example, the gaming system may operate in stand alone gaming machine mode, “thick client” mode or “thin client” mode depending on the game being played, operating conditions, and so on. Other variations will be apparent to persons skilled in the art.
Irrespective of the form, the gaming system comprises several core components. At the broadest level, the core components are a player interface 50 and a game controller 60 as illustrated in
Components of the player interface may vary from embodiment to embodiment but will typically include a credit mechanism 52 to enable a player to input credits and receive payouts, one or more displays 54 and a game play mechanism 56 comprising one or more input devices that enable a player to input game play instructions.
The game controller 60 is in data communication with the player interface and typically includes a processor 62 that processes the game play instructions in accordance with game play rules and outputs game play outcomes to the display. Typically, the game play instructions are stored as program code in a memory 64 but can also be hardwired. Herein the term “processor” is used to refer generically to any device that can process game play instructions in accordance with game play rules and may include: a microprocessor, microcontroller, programmable logic device or other computational device, a general purpose computer (e.g. a PC) or a server.
A gaming system in the form of a stand alone gaming machine 202 is illustrated in
A top box 26 may carry artwork 28, including for example pay tables and details of bonus awards and other information or images relating to the game. Further artwork and/or information may be provided on a front panel 29 of the console 12. A coin tray 30 is mounted beneath the front panel 29 for dispensing cash payouts from the gaming machine 202.
The display 14 shown in
The gaming machine 100 includes a game controller 101 having a processor 102. Instructions and data to control operation of the processor 102 are stored in a memory 103, which is in data communication with the processor 102. Typically, the gaming machine 100 will include both volatile and non-volatile memory and more than one of each type of memory, with such memories being collectively represented by the memory 103.
The gaming machine has hardware meters 104 for purposes including ensuring regulatory compliance and monitoring player credit, an input/output (I/O) interface 105 for communicating with peripheral devices of the gaming machine 100. The input/output interface 105 and/or the peripheral devices may be intelligent devices with their own memory for storing associated instructions and data for use with the input/output interface or the peripheral devices. A random number generator module 113 generates random numbers for use by the processor 102. Persons skilled in the art will appreciate that the reference to random numbers includes pseudo-random numbers.
In the example shown in
In addition, the gaming machine 100 may include a communications interface, for example a network card 112. The network card may, for example, send status information, accounting information or other information to a central controller, server or database and receive data or commands from the central controller, server or database.
It is also possible for the operative components of the gaming machine 100 to be distributed, for example input/output devices 106,107,108,109,110,111 to be provided remotely from the game controller 101.
One or more displays 204 may also be connected to the network 201. The displays 204 may, for example, be associated with one or more banks 203 of gaming machines. The displays 204 may be used to display representations associated with game play on the gaming machines 202, and/or used to display other representations, for example promotional or informational material.
In a thick client embodiment, game server 205 implements part of the game played by a player using a gaming machine 202 and the gaming machine 202 implements part of the game. With this embodiment, as both the game server and the gaming device implement part of the game, they collectively provide a game controller. A database management server 206 may manage storage of game programs and associated data for downloading or access by the gaming devices 202 in a database 206A. Typically, if the gaming system enables players to participate in a Jackpot game, a Jackpot server 207 will be provided to monitor and carry out the Jackpot game. Additional servers 212 may be provided to implement other functions depending on the embodiment implemented for the gaming venue.
In a thin client embodiment, game server 205 implements most or all of the game played by a player using a gaming machine 202 and the gaming machine 202 essentially provides only the player interface. With this embodiment, the game server 205 provides the game controller. The gaming machine will receive player instructions, pass these to the game server which will process them and return game play outcomes to the gaming machine for display. In a thin client embodiment, the gaming machines could be computer terminals, e.g. PCs running software that provides a player interface operable using standard computer input and output components.
Servers are also typically provided to assist in the administration of the gaming network 200, including for example a gaming floor management server 208, and a licensing server 209 to monitor the use of licenses relating to particular games. An administrator terminal 210 is provided to allow an administrator to run the network 201 and the devices connected to the network.
The gaming network 200 may communicate with other gaming systems, other local networks, for example a corporate network, and/or a wide area network such as the Internet, for example through a firewall 211.
Persons skilled in the art will appreciate that in accordance with known techniques, functionality at the server side of the network may be distributed over a plurality of different computers. For example, elements may be run as a single “engine” on one server or a separate server may be provided. For example, the game server 205 could run a random generator engine. Alternatively, a separate random number generator server could be provided. Further, persons skilled in the art will appreciate that a plurality of games servers could be provided to run different games or a single game server may run a plurality of different games as required by the terminals.
Embodiments of the present invention relate to gaming systems that determine a minimum prize value to be awarded for a game outcome based on a previous prize value and set a prize to be awarded for a game outcome to the minimum prize value if a provisional prize value, determined based on the game outcome, is less than the determined minimum prize value. Embodiments may be applied for any type of game, for example spinning reel, poker, keno, bingo, pin and ball, dice games etc Embodiments may be used in game systems which use mechanical random result generation processes or electronic random number generators to generate game outcomes.
An embodiment of a game system 600 for providing a game applying a minimum prize value is illustrated in
The game outcome generator 640 can include all the functions required for generating a random result, applying game rules to the random result to generate a game outcome, displaying the game outcome and determining whether a prize is to be awarded to the player for the game outcome based on game rules 610. Alternatively the game outcome generator may receive game result data generated using another module or a mechanical random result generation process and simply be adapted to apply game rules 610 to the generated game result data to determine the game outcome and whether a prize winning event has occurred. The outcome generator may also be adapted to determine a provisional value for prize to be awarded for a winning event, for example based on a wager and the winning outcome. Alternatively a provisional value for the prize to be awarded may be determined by the prize manager 650 based on a game outcome and optionally player data such as the wagered amount for a game. Player data 630 is optional in determining prizes for game outcomes as prizes may be awarded for “free play” games which do not require a wager to be placed.
The prize manager 650 is adapted to determine a minimum prize value for a current game outcome based on a previous game outcome. The prize manager 650 compares a provisional prize value for a prize to be awarded to the player for the current game outcome with the determined minimum prize value, and modifies the prize value to be awarded to the minimum prize value if the provisional prize value is less than the minimum prize value.
The minimum prize value for a current game outcome is determined based on a previous game outcome. For example the minimum prize value may be calculated from a previous prize value, for example doubling a previously awarded prize value. Alternatively where a previous game outcome met no prize wining criteria, the minimum prize value may be determined based on a game rule, for example set to a given credit value such as ten credits. In one embodiment, a series of game outcomes are calculated as a series of free spins and a minimum prize value is set by the first prize which is awarded, whether this be in the first game outcome, the second game outcome etc. (Put another way, the minimum prize is zero until an award is made). The minimum prize value for a current game outcome can be stored in memory 64 as player data 630 along with other game play instructions, including any wager data and win meter credit data 635.
The number of game outcomes for which a minimum prize value can be applied may be defined as a fixed number or based on game outcomes in accordance with game rules 610. For example, a minimum prize value may be applied for a number of “free spins” (also know as free games) in a spinning reel game, where the number of “free spins” is determined based on a predetermined combination appearing in an outcome reel spin of a previous game, such as three cats for three “free spins” or three dogs for four “free spins”. In another the number of game outcomes may be randomly selected in accordance with a random result generation process and game rules. Alternatively a minimum prize value may be applied for a series of feature games, initiated when an entry criteria is met, such as a feature game trigger symbol occurring in a base game outcome, and a minimum prize value may be determined and applied for a plurality of successive feature game outcomes until an end condition is met, such as an exit symbol appearing in a feature game outcome or a given number of feature game outcomes being generated.
In some embodiments a mathematical operation used to determine the minimum prize value may also be based on a game outcome. For example, an outcome including a doubler, or two times multiplier, symbol can cause a minimum prize value to be determined by doubling a previous prize value, whereas a three time multiplier symbol may cause a minimum prize value to be determined by tripling a previous prize value.
Alternatively a mathematical operation used to determine the minimum prize value may be randomly selected for a player from a plurality of minimum prize determination functions 625 stored in memory 64. For example, minimum prize determination functions 625 may include multipliers of a number of given values to be applied to a previous prize value, mathematical functions for application to one or more previous values, such as addition of two previous prize values to give the minimum prize value, or combinations thereof. A skilled person should appreciate that any number of mathematical functions may be applied to determine a minimum prize value based on at least one previous prize value.
Credit units or “credits” representing a monetary value are often used for wagers and prizes, the credits can be redeemed as cash or other prizes of equivalent value when a player chooses to stop playing. For example, each credit unit may represent a monetary value of 5 cents, so a player winning 10000 credits may redeem the monetary value of $500 for the 10000 credits from the gaming venue when they have finished playing.
An embodiment of a game play process where a minimum prize value is applied is illustrated in
It should be appreciated by the skilled person that in the above method, the minimum prize value for a current game for this embodiment will be at least double the minimum prize awarded for a previous game. This process can be repeated with the minimum prize value increasing for each current game outcome for the given number of game outcomes. The final value of the current prize value is then awarded to the player.
The gaming system of one embodiment provides “base games” and “feature games” wherein the minimum prize value is applied. For example the feature becomes available once eligibility criteria are met. The eligibility for a feature game may be based on an outcome of a base game, for example the appearance of a special symbol or combination of symbols in a game outcome of a base game. The player may pay an additional bet, known as an “ante bet”, for a chance to play a feature game. Alternatively payment of an ante bet alone may fulfill the eligibility criteria to play a feature game applying a minimum prize value. The amount wagered for an ante bet may determine a minimum prize value multiplier value and/or the number of game outcomes for which a minimum prize value may be applied in the feature game.
In one variation during the feature game, a series of game outcomes are generated for which a minimum prize value is applied. Feature game outcomes may be generated until an end condition is met. For example, an end condition may be that a specified number of feature game outcomes have been generated or a feature game outcome including an end condition such as a specified symbol has occurred.
An example of a game play process where the minimum prize value is applied in a feature game is illustrated in
A minimum prize value is determined 828 for the first feature game as described above. A feature game outcome is then generated 830 and displayed to the player. A provisional prize value for the game outcome is also determined and can be displayed to the player along with the game outcome. The provisional prize value may be a prize value determined for the currently generated game outcome only or may be a cumulative prize value based on a prize value for a current game outcome added to a cumulative prize total of prizes to be awarded for previous game outcomes, for example a cumulative prize total stored in a win meter for the feature game. The provisional prize value is compared with the minimum prize value 840. If the provisional prize value is less than the minimum prize value, then the prize is set to the minimum prize value 850. If the provisional prize value is greater than the minimum prize value then the prize to be awarded is set to the provisional prize value 860. The prize for the feature game outcome is awarded 870 and the previous prize value updated 875 based on the prize awarded.
The end criteria for the feature are checked 880 to determine whether the feature game is completed, for example if a predetermined number of feature game outcomes have been generated, an end symbol occurred in the feature game outcome or the like. If the feature game is not completed then the game play process continues with a new minimum prize value determined 885 based on the previous prize value and a further feature game outcome 830 is generated and the new minimum value applied etc until the end criteria are met. Once the end criteria are met the feature game is completed and the game play process returns to the start for the next base game 810.
It should be appreciated by a person skilled in the art that generating game outcome is used herein to refer to a process which can give rise to a win entitlement for a player. For example in a spinning reel embodiment, generating a game outcome may involve spinning all reels to cause a set of symbols to be displayed to the player for win entitlement to be determined based on combinations of symbols appearing the in the displayed symbol set. Generating a game outcome may also involve changing only part of a symbol set, for example by spinning one reel while others are held, holding some selected symbols while reels are spun behind the held symbols or nudging a reel, to generate a new symbol set for which win entitlement can be determined. Similarly, for other styles of games generating a game outcome can occur by modifying part of a previous game outcome to generate a new game outcome for win entitlement assessment to determine a prize to be awarded for the game outcome. For example, in a card game dealing a new card to add to a hand or in a dice game re-rolling one of a plurality of dice may constitute generating a new game outcome. Game rules can define what actions constitute generating a new game outcome, and it will be appreciated by a person skilled in the art that what constitutes generating a new game outcome can vary for different game embodiments.
Modifications to the exemplary game process are envisaged within the scope of various embodiments. For example, a feature game outcome may award generation of further feature game outcomes or a plurality of base games may be played before a feature game is started. A minimum prize value may be determined using a different mathematical function to determine the minimum prize value for each feature game. The feature game may be a different game from a base game, for example a base game may be a spinning reel game and the feature game a dice game. These and any other modifications are contemplated within the scope of the present invention. Feature games may be “free play” games or have a different betting structure to base games. Feature games may be similar to a base game but introduce different features such as additional symbols or prize patterns. Alternatively prize values for feature game outcomes may differ from those of a base game.
An outcome of one or more base games, as well as fulfilling eligibility criteria for a feature game may also be used to determine the mathematical functions used to determine minimum prize values for one or more feature games. For example, a series of base games may be played before a feature game can be played. For each of these base games, if a specified outcome occurs this causes a mathematical function to be made available for selection for determining a minimum prize value during a feature game. For example, each time a combination of three dogs appears in a game outcome the number of times a predetermined mathematical function, say a two times multiplier, can be added to a set of mathematical functions used to determine a minimum prize values for a feature game. The size of the set of mathematical functions can be used to determine the number of game outcomes generated for a feature game, with one of the mathematical functions used to determine the minimum prize value for each game outcome until each has been used once. The size of such a set of mathematical functions or the mathematical functions eligible for adding to the set may be fixed, defined in game rules or based on the amount of an ante bet.
In an alternative example, for a spinning reel game, each time a combination of three cats appears in a win line of the game a two times multiplier may be added to the player's set of minimum prize value determining functions. Each time a combination of four cats appears on a win line a three times multiplier is added to the set of minimum prize value determining functions. These multipliers may be selectively applied during the play of one or more feature games. Selecting which mathematical function to apply to determine a minimum prize value may be based on a predetermined order, such as the order in which the player won the minimum prize determination functions or applying the function in a highest multiplier to lowest multiplier order. Alternatively selecting which minimum prize determination function to apply can be done using pseudo-random number generation performed by a game controller processor. If a set of minimum prize value determining functions are not all applied for a sequence of feature game outcomes, any unused minimum prize value determining functions may be lost or carried over for use in current feature games, dependent on the game rules of the particular game.
In the embodiments described above, a new minimum prize value is determined for each game outcome in a series. In an alternative embodiment a minimum prize value may be compared with a provisional prize value based on the outcome of two or more games, for example the provisional prize value may be selected as the best outcome out of a series of three game outcomes, alternatively the provisional prize outcome may be a cumulative total of prize values for a series of four game outcomes. The number of game outcomes in a series may be predetermined or selected based on game rules. It should be appreciated that it will be generally desirable for a player to have a provisional prize value for a game outcome (or series of outcomes) greater than the determined minimum prize value for the game outcome as this will increase the minimum prize value, and hence prize award guarantee, for current game outcomes.
Some exemplary embodiments of gaming methods, controllers and systems applying a minimum prize value based on a previous game outcome have been described herein. A person skilled in the art should readily appreciate that the minimum prize value may be applied in many alternative embodiments. Any modifications or alterations to the minimum prize value described herein are envisaged within the scope of the present application including that features of the embodiments and examples may be used to form further embodiments.
In the preceding description, except where the context requires otherwise due to express language or necessary implication, the word “comprise” or variations such as “comprises” or “comprising” is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments.
It is to be understood that, if any prior art is referred to herein, such reference does not constitute an admission that the publication forms a part of the common general knowledge in the art, in any country.
In the following non limiting example a player is playing a spinning reel game. According to game rules the previous prize value used to determine the minimum prize value is the player's cumulative total prize value for the feature game. The minimum prize value determination function in this example is defined by the game rules as a two times multiplier. The minimum prize value is applied for of a series of three feature games.
In this example, game rules define provisional prize values as the sum of a prize value for an outcome and the previously awarded prize value.
A player triggers a series of three feature games from a base game. During the feature games the play of the game is free.
The initial minimum prize value is determined to be zero as the player has a cumulative total of zero credits for the feature game before the first reel spin of the feature game.
A game outcome generated for the first free reel spin is illustrated in
For the second free spin the minimum prize value 930 is determined by doubling the previous prize value of five hundred credits, thus the minimum prize value 930 is one thousand credits.
The outcome for the second free reel spin is illustrated in
For the third free spin the minimum prize value 940 is determined by doubling the previous prize value of eleven hundred credits, thus the minimum prize value 940 is twenty two hundred credits.

According to game rules the previous prize value used to determine the minimum prize value is the player's cumulative total prize value for the feature game. The minimum prize value determination function in this example is defined by the game rules as a two times multiplier. The minimum prize value is applied for of a series of three feature games.
In this example, game rules define provisional prize values as the sum of a prize value for an outcome and the previously awarded prize value.
A player triggers a series of four feature games from a base game. During the feature games the play of the game is free.
The initial minimum prize value is determined to be zero as the player has a cumulative total of zero credits for the feature game before the first reel spin of the feature game.
