General construction of gaming system The gaming system can take a number of different forms. In 25 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 30 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 35 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" 3223095_1 (GHMatteos) P75997.AU.2 - 10 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 5 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 10 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, 15 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 20 components are a player interface 50 and a game controller 60 as illustrated in Figure 1. The player interface is arranged to enable manual interaction between a player and the gaming system and for this purpose includes the input/output components required for the player to enter 25 instructions and play the game. 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 30 and receive payouts, one or more displays 54, a game play mechanism 56 comprised of one or more input devices that enable a player to input game play instructions (e.g. to place bets), and one or more speakers 58. 35 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 3223095_1 (GHMatter) P75997AU-2 - 11 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 5 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. 10 A gaming system in the form of a stand alone gaming machine 10 is illustrated in Figure 2. The gaming machine 10 includes a console 12 having a display 14 on which are displayed representations of a game 16 that can be played is by a player. A mid-trim 20 of the gaming machine 10 houses a bank of buttons 22 for enabling a player to interact with the gaming machine, in particular during game play. The mid-trim 20 also houses a credit input mechanism 24 which in this example includes a coin input 20 chute 24A and a bill collector 24B. Other credit input mechanisms may also be employed, for example, a card reader for reading a smart card, debit card or credit card. A player marketing module (not shown) having a reading device may also be provided for the purpose of 25 reading a player tracking device, for example as part of a loyalty program. The player tracking device may be in the form of a card, flash drive or any other portable storage medium capable of being read by the reading device. 30 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 35 beneath the front panel 29 for dispensing cash payouts from the gaming machine 10. 32230951 (GHMatters) P75997.AU.2 - 12 The display 14 shown in Figure 2 is in the form of a video display unit, particularly a cathode ray tube screen device. Alternatively, the display 14 may be a liquid crystal display, plasma screen, any other suitable video 5 display unit, or the visible portion of an electromechanical device. The top box 26 may also include a display, for example a video display unit, which may be of the same type as the display 14, or of a different type. 10 Figure 3 shows a block diagram of operative components of a typical gaming machine which may be the same as or different to the gaming machine of Figure 2. 15 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 20 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 25 including ensuring regulatory compliance and monitoring player credit, an input/output (I/0) 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 30 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 35 random numbers includes pseudo-random numbers. In the example shown in Figure 3, a player interface 120 3223095_1 (GHMatlers) P75997.AU 2 - 13 includes peripheral devices that communicate with the game controller 101 comprise one or more displays 106, a touch screen and/or buttons 107, a card and/or ticket reader 108, a printer 109, a bill acceptor and/or coin input 5 mechanism 110 and a coin output mechanism 111. Additional hardware may be included as part of the gaming machine 100, or hardware may be omitted as required for the specific implementation. For example, while buttons or touch screens are typically used in gaming machines to 10 allow a player to place a wager and initiate a play of a game any input device that enables the player to input game play instructions may be used. In addition, the gaming machine 100 may include a 15 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 20 database. Figure 4 shows a block diagram of the main components of an exemplary memory 103. The memory 103 includes RAM 103A, EPROM 103B and a mass storage device 103C. The RAM 25 103A typically temporarily holds program files for execution by the processor 102 and related data. The EPROM 103B may be a boot ROM device and/or may contain some system or game related code. The mass storage device 103C is typically used to store game programs, the 30 integrity of which may be verified and/or authenticated by the processor 102 using protected code from the EPROM 103B or elsewhere. It is also possible for the operative components of the 35 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. 3223095_1 (GHMatters) P75997.AU.2 - 14 Figure 5 shows a gaming system 200 in accordance with an alternative embodiment. The gaming system 200 includes a network 201, which for example may be an Ethernet network. 5 Gaming machines 202, shown arranged in three banks 203 of two gaming machines 202 in Figure 5, are connected to the network 201. The gaming machines 202 provide a player operable interface and may be the same as the gaming machines 10,100 shown in Figures 2 and 3, or may have io simplified functionality depending on the requirements for implementing game play. While banks 203 of two gaming machines are illustrated in Figure 5, banks of one, three or more gaming machines are also envisaged. One or more displays 204 may also be connected to the 15 network 201. For example, the displays 204 may 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 20 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 25 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 30 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 perform accounting functions for the Jackpot game. A loyalty program server 212 may also be provided. 35 In a thin client embodiment, game server 205 implements most or all of the game played by a player using a gaming 3223095_1 (GHMStter) P75997AU2 - 15 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 5 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 10 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 15 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. 20 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, for example through a firewall 211. 25 Persons skilled in the art will appreciate that in accordance with known techniques, functionality at the C 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 30 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 game servers could be 35 provided to run different games or a single game server may run a plurality of different games as required by the terminals. 3223095_1 (GHMatters) P75997 AU.2 - 16 Further detail of gaming system The outcome generator 622 operates in response to the 5 player's operation of game play mechanism 56 to generate a game outcome which will then be evaluated by prize evaluator 623. The player's operation of game play mechanism establishes the player's win entitlement for the game based on the bet (wager) the player makes for the 10 game. Persons skilled in the art will appreciate that a player's win entitlement will vary from game to game and may or may not be dependent on player selections. In most spinning is reel games, it is typical for the player's entitlement to be affected by the amount they wager and selections they make (i.e. the nature of the wager). For example, a player's win entitlement may be based on how many lines they will play in each game - i.e. a minimum of one line 20 up to the maximum number of lines allowed by the game (noting that not all permutations of win lines may be available for selection. Such win lines are typically formed by a combination of displayed symbol positions, one from each reel, the symbol positions being located 25 relative to one another such that they form a line. In many games, the player's win entitlement is not strictly limited to the lines they have selected, for example, "scatter" pays are awarded independently of a 30 players selection of pay lines and are an inherent part of the win entitlement. The win entitlement is not always purchased - e.g. a series of free games may be awarded. Once the player has operated the game play mechanism 56 to 35 place a bet, the first part of forming the game outcome is for a symbol selector 622A to select sets of symbols having a designated sequence from symbols specified by 3223095_1 (GHMatters) P75997 AU.2 - 17 symbol data 641 for display on display 54 using random number generator 621. For example, in a spinning reel game, the symbol selector selects a set of symbols for each reel. In the embodiment, the symbol selector 622A 5 selects more symbols for display on display 54 that will ultimately be evaluated by award determiner 622B based on prize data 644 to determine whether the selected symbols form any winning outcomes. In one example, this is by selecting more symbols for each set than can fit in the 10 evaluation area. In another example, this is by selecting more sets of symbols than will fit in the evaluation area. Display 54 displays an evaluation area 54A. A position selector 622B of outcome generator selects where each set is of selected symbols will be displayed relative to the evaluation area. For example, by symbol selector 622A selecting where a designated symbol (such as the middle symbol) of each set of symbols should be placed relative to the evaluation area using a value obtained from random 20 number generator 621 and a probability table which specifies a relationship between the value and position. One example of selecting symbols is for the symbol selector 622A to select symbols for display from a plurality of symbol sets corresponding to respective ones 25 of a plurality of spinning reels. The symbol sets 641 specify a sequence of symbols for each reel such that the symbol selector 622A can select a symbol by selecting a stopping position in the sequence to correspond to a display position - e.g. the middle display position. In 30 one example, five symbols of each of five reels may be displayed such that twenty-five symbols are displayed. The evaluation area 54A may fit, for example, at fifteen symbols. In the embodiment, constraints are placed on where the sets are positioned to ensure that the 35 evaluation area is filled with symbols. Thus, in the embodiment, the display positions are filled with selected symbol from the symbol sequence and the display positions 3223095_1 (GHMatters) P75997.AU.2 - 18 used to fill the evaluation area are independently chosen. In one example embodiment, suitable for a spinning reel type game, the evaluation area has a plurality of s evaluation positions arranged in a grid such that the grid has a plurality of rows and columns. In this embodiment, each set of display positions is associated with a specific column, such that selecting the position is performed by selecting in which row a designated display 10 position of the set of display positions is to be displayed. As a result, the symbols are selected for display positions but the actual positions of those display positions relative to the evaluation area may vary. 15 In a spinning reel embodiment, this is displayed on the display 54 by a plurality of sets of display positions at which the selected symbols will be displayed as moving relative to the evaluation area 54A while the reels are 20 spun. The selected symbols and positions for the display positions are advised to the display controller 624 which causes them to be displayed on display 54 relative to evaluation area. The display positions stop such that a subset of them are displayed in the evaluation area and 25 then the reels stop to show which symbols will be evaluated. Accordingly, it will be appreciated that the display positions could be stopped before, after or simultaneously with the reels. 30 Once the symbols are stopped in the evaluation area, the award determiner 623 determines whether the symbols in the evaluation area 54A correspond to a winning outcome specified by prize data 644 and updates meters 645 to reflect any wins. 35 Persons skilled in the art will appreciate that rather than selecting the vertical positioning of the display 32230951 (GHMatters) P75997AU.2 - 19 positions, the horizontal position or column can be selected as well or instead. In one example, there are six reels and three display positions per reel but only five reels can fit in the display area as there are more 5 display positions than evaluation positions. Persons skilled in the art will also appreciate that in some embodiments not all the reels move. For example, in one embodiment only one reel moves. In another embodiment 10 some of the reels may have different numbers of display positions. In one example, only one reel may be associated with more display positions than the evaluation area such that it is the only reel which moves. In other examples, more than one but less than all the reels are have more is display positions than the evaluation area. In some embodiments the numbers of display positions of the reels may differ for example such that some have 3 display positions while other have 5. In some embodiments, the number of reels that move at any time may be dependent on 20 one or more conditions such as bet type, bet amount, occurrences in the game, the stage of the game etc. The method 700 of an embodiment is summarised in Figure 7. Symbols are selected 710 for a plurality of sets of 25 display positions. The positions of the display positions relative to the evaluation area are also selected 720. In a reel embodiment, the reels are displayed 730 as spinning while the display positions move. Spinning and movement is then stopped 740 and the outcome is evaluated 750 to 30 determine whether to award any prize. Persons skilled in the art will also appreciate that the further aspect of the method will be apparent from the description of the gaming system and that the method of 35 the embodiment could be embodied in program code. The program code could be supplied in a number of ways, for example on a computer readable medium, such as a disc or a 3223095.1 (GHMaters) P75997.AU.2 - 20 memory (for example, that could replace part of memory 103) or as a data signal (for example, by transmitting it from a server). 5 Example An example of a spinning reel type game is shown in Figures 8A to 8C. In each of Figures 8A to 8C there are five reels 811-815, each having five display positions and 10 symbols are selected for each of the five display positions. The evaluation area in the form of pay window 820 is sized such that only three symbols of each reel will fit. 15 Figure 8A shows a starting position 800A where the middle three symbols of each reel 811-815 are displayed within the pay window 820. Figure 8B shows a moving position BOOA where the display positions of each reel are moving relative to the pay window 820 as indicated by arrows, 20 831,832,834 & 835 to thereby give the advantageous impression that the reels are moving. Figure 8C shows a stop position 800C where the display positions of each reel (numbered left to right) have stopped such that the following display positions are in the evaluation area: 25 first reel - top three symbols second reel - bottom three symbols third reel - middle three symbols fourth reel - top three symbols fifth reel - bottom three symbols. 30 The game outcome is then evaluated by award determiner 623 based on the symbols within the pay window 620. It will be understood to persons skilled in the art of the 35 invention that many other modifications may be made without departing from the spirit and scope of the invention. In particular, that features described herein 3223005_1 (GHMatlers) P75997.AU.2 - 21 can be used to form further embodiments. It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute 5 an admission that the publication forms a part of the common general knowledge in the art, in Australia or any other country. In the claims which follow and in the preceding 10 description of the invention, 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 15 not to preclude the presence or addition of further features in various embodiments of the invention. 3223095-1 (GHMatters) P75997.AU.2
