The display 106B may display artwork, including for example, pay tables and details of bonus awards and other information or images relating to the game. In alternative gaming consoles the display 106B may be omitted, optionally replaced by a static display.
  • [0032]
    A credit input including a coin input 110A and/or bill collector 110B allows a player to provide credit for wagering and a coin output 111 is provided for cash payouts from the gaming console 114. A card and/or ticket reader 108 and a printer 109 may be provided to provide player tracking, cashless game play or other gaming and non-gaming related functions.
  • [0033]
    FIG. 2 shows a block diagram of a gaming machine, generally referenced by arrow 100, suitable for implementing certain embodiments of the present invention. The gaming machine 100 may include the gaming console 114 shown in FIG. 1 and accordingly like reference numerals have been used to describe like components in FIGS. 1 and 2.
  • [0034]
    The gaming machine 100 includes a game controller 101, which in the illustrated example includes a computational device 102, which may be a microprocessor, microcontroller, programmable logic device or other suitable device. Instructions and data to control operation of the computational device 102 are stored in a memory 103, which is in data communication with, or forms part of, the computational device 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 instructions to cause the game controller 101 to implement certain embodiments of the present invention will be stored in the memory 103. The instructions and data for controlling operation of the computational device 102 may be stored on a computer readable medium from which they are loaded into the gaming machine memory 103. The instructions and data may be conveyed to the gaming machine by means of a data signal in a transmission channel. Examples of such transmission channels include network connections, the Internet or an intranet and wireless communication channels.
  • [0035]
    The game controller 101 may include hardware credit meters 104 for the purposes of regulatory compliance and also include an input/output (I/O) interface 105 for communicating with the 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 instructions and data.
  • [0036]
    In the example shown in FIG. 2, the peripheral devices that communicate with the controller are the displays 106, bank of buttons/touch screen 107, the card and/or ticket reader 108, the printer 109, a bill acceptor and/or coin input 110 and a coin output 111. Additional devices may be included as part of the gaming machine 100, or devices omitted based on the specific implementation.
  • [0037]
    The bank of buttons 107A and/or touch screen 107B together with one or both of the displays 106 may provide a user interface 115 through which the gaming machine 100 and player communicate. If a card/ticket reader 108 is provided, this may also form part of the user interface 115.
  • [0038]
    In addition, the gaming machine 100 may include a communications interface, for example a network card 112. The network card 112, 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. The network card 112 may also enable communication with a central player account, allowing cashless gaming. One or more of the peripheral devices, for example the card/ticket reader 108 may be able to communicate directly with the network card 112. The network card 112 and the I/O interface 105 may be suitably implemented as a single machine communications interface.
  • [0039]
    The game controller 101 may also include a random number generator 113, which generates a series of random numbers that are used by the computational device 102 to determine the outcomes of games played on the gaming machine 100.
  • [0040]
    The game controller 101 may have distributed hardware and software components that communicate with each other directly or through a network or other communication channel. The game controller 101 may also be located in part or in its entirety remote from the user interface 115. Also, the computational device 102 may include a plurality of devices, which may be local or remote from each other. Instructions and data for controlling the operation of the user interface 115 may be conveyed to the user interface 115 by means of a data signal in a transmission channel. The user interface 115 may be a computational device, for example a personal computer, used by a person to play a game provided from a remote game controller 101.
  • [0041]
    FIG. 3 shows an exemplary block diagram of the main components of the memory 103. The RAM 103A typically temporarily holds instructions and data related to the execution of game programs and communication functions performed by the computational controller 102. The EPROM 103B may be a boot ROM device and/or may contain system and game related code. The mass storage device 103C may be used to store game programs, the integrity of which may be verified and/or authenticated by the computational controller 102 using protected code from the EPROM 103B or elsewhere.
  • [0042]
    FIG. 4 shows a gaming system 200 in the form of a network of devices. The gaming system 200 includes a network infrastructure 201, which for example may be in the form of an Ethernet network. Alternatively, a wireless network and/or direct communication channels, or a different type of network may be used to link the gaming machines to a server, each other and/or other devices. Gaming consoles 114, shown arranged in three banks 203 of two gaming consoles 114 in FIG. 4, are connected to the network infrastructure 201. The gaming consoles 114 may form part or all of a gaming machine 100. Single gaming consoles 114 and banks 203 containing three or more gaming devices 202 may also be connected to the network infrastructure 201, which may also include bank controllers, hubs, routers, bridges to other networks and other devices (not shown).
  • [0043]
    One or more displays 204 may also be connected to the network 201. The displays 204 may, for example, be associated with a bank 203 of gaming consoles 114. The displays 204 may be used to display representations associated with game play on the gaming devices 202, and/or used to display other representations, for example promotional or informational material.
  • [0044]
    Servers may also be connected to the network 201. For example, a game server 205 may generate game outcomes for games played on one or more of the gaming consoles 114, a database management server 206 may manage the storage of game programs and associated data in a database 206A so that they are available for downloading to, or access by, game controllers 101, and a jackpot server 207 may control one or more jackpots for the gaming system 200.
  • [0045]
    Further servers may be provided to assist in the administration of the gaming system 200, including for example a gaming floor management server 208, and a licensing server 209 to monitor the use of licenses to particular games. An administrator terminal 210 is provided to allow an administrator to manage the network 201 and the devices connected to the network. The different servers depicted can be distinct physical servers or logically distinct server processes running on a single physical server.
  • [0046]
    The gaming system 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 through a firewall 211.
  • [0047]
    FIGS. 5A and 5B show process flow diagrams of a process performed in accordance with embodiments of the present invention. The process may be performed by the gaming system 200, in which the gaming consoles 114 each include game controllers 101 to form gaming machines 100. However, those skilled in the relevant arts will appreciate that the process will also be able to be implemented by other gaming systems.
  • [0048]
    The processes of FIGS. 5A and 5B and the examples of FIGS. 6A-6E and 7A-7D are described primarily with reference to a spinning reel game in which a set of reels spin and halt to display an array of symbols. In one arrangement there are 5 spinning reels which halt to display three symbols each, ie a symbol array of 5×3 symbols is presented on the display. The spinning reels may be mechanical reels each bearing a sequence of symbols. Alternatively, the reels may be a computer animation that is rendered to display 106 to show the set of spinning reels. It will, however, be understood that the game of FIGS. 5A and 5B can also be applied to other types of games in which a set of symbols is selected and presented on a display. Examples of such games include poker games, keno games, bingo, pin and ball games and dice games.
  • [0049]
    Initially, the game controller 101 monitors the bill acceptor and/or coin input 110 and/or information received by the card/ticket reader 108 or network card 112 for a deposit of credit and in response causes the hardware meters 104 to increment according to the denomination of the game. The game controller 101 then monitors the user interface 107 for the input of a wager.
  • [0050]
    If there are sufficient credits in the meters 104 to support the wager, a game play is commenced by the game controller 101. The method 500 of FIG. 5A shows a feature game that is triggered from a base game. In stage 502 the game controller 101 determines whether one or more eligibility criteria triggering the feature have been satisfied. There are many criteria that may be used in order to trigger a feature game. Examples include an event in the base game (such as a display of a specified combination of symbols) or a machine event, such as an output triggered by the random number generator 113. The feature may also be triggered by a system event in gaming system 200. For example, if an accumulating jackpot reaches a specified threshold, a feature may be triggered. Specified events in a player-tracking system may also trigger a feature. For example, if a player has played a specified number of games or wagered a specified number of credits, a feature may be triggered. In a further example, the player may be required to purchase the feature or to place an ante bet that enables the feature to be triggered upon occurrence of a specified game event.
  • [0051]
    Once the feature has been triggered, there are further criteria that determine the duration of the feature. For example, the feature may have a fixed duration. Alternatively, a series of game plays in the feature may end if an end condition occurs. A series of feature games may also be extended if an extension condition occurs in the feature.
  • [0052]
    In some arrangements the feature is differentiated from the base game. For example, the cost of the game may change (for example, the feature games may be free), the prize values may change, the prize patterns may change and/or the set of symbols may change. New symbols may be introduced or the function of symbols may change. An example is a feature game in which one or more specified symbols become wild during the feature. In addition, the game itself may change, for example from a base game that is a spinning reel game to a card game in the feature.
  • [0053]
    At stage 504, the game controller initialises a set of award adjusters. The value of the award adjusters may be displayed to the player, for example, via display 106A. Each award adjuster corresponds to a specified symbol that is potentially displayed in the feature game. For example, the specified symbols may be included in the set of symbols associated with spinning reels in a spinning reel game. The specified symbols may be added to the total set of symbols for the feature game. Alternatively, the specified symbols may already be present in the symbol set used in the base game.
  • [0054]
    In one arrangement, each of the award adjusters is initialised to a value of 1 for each of the corresponding specified symbols. However, in other arrangements the award adjusters need not start at 1, but rather at a nominated value chosen by the game designer and defined in the rules of the game. In one arrangement all of the award adjusters are initialised to the same value. Alternatively, the initial value of the award adjusters may be different for different specified symbols. In some arrangements the initial values may be randomly selected.
  • [0055]
    In step 506, game play commences and a set of symbols is displayed on display 106. For example, in a spinning reel game, the reels are spun and halted to display a 5×3 array of symbols.
  • [0056]
    At stage 508 the game controller checks whether one or more of the specified symbols have been displayed. If so, then in step 510 the current value of the award adjuster corresponding to the displayed specified symbol is changed. In one arrangement, the award adjuster increases by a quantum of 1 for each of the corresponding special symbols which are displayed at the conclusion of step 506.
  • [0057]
    In other arrangements, the increment is not 1, but may be a larger value. Different increments may apply to different award adjusters. The value of the award adjustors may be capped in some arrangements.
  • [0058]
    In other arrangements, a display of a specified symbol may cause the corresponding award adjuster to decrease. A lower limit may be specified. For example, the game rules may determine that an award adjuster cannot fall below a value of 1. The amount used to increment or decrement the award adjusters may depend on which feature game is in play.
  • [0059]
    Once the award adjusters have been changed in step 510, process flow continues to step 512, in which the game controller checks whether a winning outcome has been displayed.
  • [0060]
    If none of the specified symbols has been displayed (the No option of step 508) then process flow also continues to step 512 to check whether a winning outcome has occurred.
  • [0061]
    If there is no winning outcome (the No option of step 512) then process flow returns to step 502 to check whether the eligibility criteria are still satisfied. If so, the feature game continues. If the eligibility criteria are no longer satisfied, the feature may terminate.
  • [0062]
    If a winning outcome is displayed, in process 514 the game controller checks whether the winning outcome includes one or more of the specified symbols.
  • [0063]
    If there are no specified symbols in the winning outcome then the award specified for the game is awarded in step 516 and process flow returns to step 502 to check whether the eligibility criteria for the feature are still satisfied.
  • [0064]
    If there are one or more of the specified symbols in the winning outcome (the Yes option of step 514) then in process 518 the game controller adjusts the award dependent on the current value of the award adjusters.
  • [0065]
    In one arrangement the award adjusters are multipliers, and the value of the award is multiplied by any multipliers associated with symbols appearing in the winning outcome.
  • [0066]
    In other arrangements, the award adjusters may affect the award in a different manner. For example, the value of the award adjuster may be added to the normal prize. For example, an amount of 50 may be added to the normal award for each CAT symbol displayed in step 506.
  • [0067]
    FIGS. 6A-6E illustrate the method of FIG. 5A. FIG. 6A shows an example of a display rendered to display 106A in the course of a base game. In the example, the base game is a spinning reel game that displays a 5×3 array of symbols 604.
  • [0068]
    A credit space 602 is displayed on displays 106 to show the player's current credit, bet and any wins. In the example, the player has bet 5 credits (1 credit on 3 lines) and wins 10 credits for the 3 DOG symbols displayed adjacent to one another on the middle row of the symbol array 604. According to the rules of the game of the example, the 3 DOG symbols also initiate a series of 3 feature games.
  • [0069]
    FIG. 6B shows how the displayed information changes when the feature is triggered. In the example, the feature games are free and any CAT or MOUSE symbol in a winning combination will multiply the value of the win by the displayed multiplier value. Each time a CAT or MOUSE symbol appears anywhere in the symbol array during the feature game, a corresponding multiplier is incremented by 1.
  • [0070]
    The information in the credit space 606 is augmented to show a multiplier 610 for the CAT symbol and a multiplier 612 for the MOUSE symbol. An indication of the number of free games remaining is also displayed.
  • [0071]
    FIG. 6C shows the outcome of the first feature game. The 5×3 symbol array 616 is shown, including 2 MOUSE symbols and 3 CAT symbols. In the credit space 614, the CAT multiplier is incremented to 4 and the MOUSE multiplier is incremented to 3. The credit space 614 shows that there are 2 free games remaining.
  • [0072]
    There are no wins in the array 616 and so no awards are made.
  • [0073]
    The outcome of the second feature game is shown in FIG. 6D. The displayed array of symbols 620 includes 1 CAT symbol, so the CAT multiplier value increases to 5. Since there are 3 MOUSE symbols, the MOUSE multiplier increases to a value of 6, as shown in the credit space 618.
  • [0074]
    The check for winning outcomes reveals that there is only one winning combination on the 3 purchased lines, namely the 3 adjacent MOUSE symbols on the centre line. This symbol combination would ordinarily give an award of 10 but in the present case the award is multiplied by 6 and so the adjusted prize is 60 and the win meter increments as shown in the credit space 618.
  • [0075]
    FIG. 6E shows the outcome of the third feature game. The reels stop to show the symbol array 624, which includes 5 CAT symbols so the CAT multiplier value increases to 10. There are 3 MOUSE symbols in the array 624, so the MOUSE multiplier increases to 9.
  • [0076]
    In evaluating the prizes, there is only a single winning combination on the 3 purchased lines, namely the 5 CAT symbols shown on the bottom of the 3 lines. This symbol combination would normally pay 50 but in this case will be multiplied by 10. The adjusted award is thus 500 as illustrated in the credit space 622.
  • [0077]
    The feature sequence is then over and the game returns to the base game.
  • [0078]
    In other arrangements, the symbol-specific multipliers need not be restricted to a feature game, but may be used in general game play. This arrangement is illustrated in method 550 in FIG. 5B. Processes 504-518 are as described with reference to FIG. 5A, and will not be discussed further. Method 550 does not have the initial step of determining whether the eligibility criteria for a base game have been satisfied.
  • [0079]
    One difference between method 550 and method 500 is that when an award has been adjusted according to an award adjuster in method 550, the corresponding award adjuster is reset to a default value in step 568.
  • [0080]
    An example of a game played in accordance with the method 550 is shown in FIGS. 7A-7D.
  • [0081]
    As shown in FIG. 7A, the player plays a normal game at 1 credit per line. Three lines are played so the total bet is 3, as shown in the credit space 702.
  • [0082]
    One MOUSE symbol and 1 CAT symbol appear in the symbol array 704 and so the CAT and MOUSE counters in the credit space 702 are incremented by 1. There is a winning pattern on the centre line of 3 adjacent 10 symbols. The player wins 10 credits. Because of the winning outcome does not include a CAT or a MOUSE symbol, the award is not adjusted.
  • [0083]
    FIG. 7B shows an outcome from the next reel spin. The player plays a normal game at 1 credit per line. Three lines are played so the total bet is 3. The credit meter has increased by 10 for the prior win and has been decreased by 3 for the wager.
  • [0084]
    One MOUSE symbol and 2 CAT symbols appear in the symbol array 708 and so the CAT and MOUSE counters are incremented by 1 and 2 respectively, as shown in the credit space 706. There are no winning outcomes in the symbol array 708.
  • [0085]
    FIG. 7C shows the outcome of a third reel spin. The player bets 3 and so the credit meter decrements by a value of 3. The symbol array 712 includes 3 CAT symbols and so the CAT multiplier increments by 3 to a value of 7. There is winning outcome in the symbol array 712, namely 3 adjacent CAT symbols in the top line. The normal prize for 3 CATs is 20. Accordingly, the player is paid an adjusted award of 7×20=140.
  • [0086]
    FIG. 7D shows the outcome of a fourth reel spin. As seen in the credit space 714, the credit meter has increased by the previous win and has been decremented by the bet of 3. The CAT multiplier has been reset to a value of 1. One MOUSE symbol has been displayed in the symbol array 716, and so the MOUSE multiplier is increased to a value of 4.
  • [0087]
    There are no winning outcomes in the symbol array 716 and so no awards are made.
  • [0088]
    In an alternative embodiment, one symbol may cause, or result in eligibility for, adjustment of a multiplier or other award adjustor, but another symbol may influence how much the multiplier is changed. For example, if the MOUSE symbol is associated with a corresponding multiplier, that multiplier may be increased by one if the MOUSE symbol occurs alone, or may increase by two if a CHEESE symbol is also presented on the display. The CHEESE symbol could be presented anywhere on the display, or may have to be displayed in a certain location or in one of a number of certain locations. An example of the latter is that the CHEESE symbol may have to be displayed adjacent to the MOUSE symbol.
  • [0089]
    In another alternative, display of the MOUSE symbol alone may not result in any change in the corresponding multiplier, the multiplier only being changed when the MOUSE symbol is displayed with one or more CHEESE symbols. The amount of the change may be dependent on the number of CHEESE symbols. The amount of the change may instead be dependent on both the number of CHEESE symbols and the number of MOUSE symbols.
  • [0090]
    In the two alternatives, the CHEESE symbol could itself have a corresponding award adjustor. Otherwise the CHEESE symbol may have other functions in the game, or have the sole function of influencing the amount that the award adjustor is changed when the MOUSE symbol occurs.
  • [0091]
