Embodiment 10 An embodiment provides a gaming system where a player plays, at least one game, and preferably a sequence of games. A plurality of symbols are provided for game play and a 15 plurality of locations are provided from which game outcomes can be determined by symbols occurring at locations. One of the symbols is allocated as a trigger symbol and during play of an initial game, on the occurrence of the trigger symbol there is triggering of 20 the playing of a feature game. When a game outcome occurs in the feature game, an award is made if a symbol in the outcome occurs at that particular location. The gaming system may be provided in a number of different 25 forms. 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. 30 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 35 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, 4920316_1 (GHMatters) P72661.AU.3 - 6 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 5 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 10 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 15 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 20 several core components. At the broadest level, the core 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 25 input/output components required for the player to enter instructions and play the game. Components of the player interface may vary from embodiment to embodiment but will typically include a 30 credit mechanism 52 to enable a player to input credits and receive payouts, one or more displays 54 and a game play mechanism 56 that enables a player to input game play instructions. 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 4920316_1 (GHMatters) P72661.AU.3 - 7 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 is displayed representations of a game 16 that can be played 15 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 may be provided 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. 4920316_1 (GHMatters) P72661.AU.3 - 8 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/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 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 4920316_1 (GHMatters) P72661.AU.3 - 9 includes peripheral devices that communicate with the game controller 101 comprise one or more displays 106, a touch screen 107, a card and/or ticket reader 108, a printer 109, a bill acceptor and/or coin input mechanism 110 and a 5 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. 10 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 15 data or commands from the central controller, server or database. Figure 4 shows a block diagram of the main components of an exemplary memory 103. The memory 103 includes RAM 20 103A, EPROM 103B and a mass storage device 103C. The RAM 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 25 103C is typically used to store game programs, the integrity of which may be verified and/or authenticated by the processor 102 using protected code from the EPROM 103B or elsewhere. 30 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. 35 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. 4920316_1 (GHMatters) P72661.AU.3 - 10 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 5 machines 10,100 shown in Figures 2 and 3, or may have 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. 10 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 15 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 20 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 25 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 carry out 30 the accounting in respect of the Jackpot game. A loyalty program server 212 may also be provided. In a thin client embodiment, game server 205 implements most or all of the game played by a player using a gaming 35 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 4920316_1 (GHMatters) P72661.AU.3 - 11 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 5 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 10 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 15 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, 20 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 25 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 30 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. 35 The embodiment may be implemented in relation to a game with multiple columns such as a spinning reel type game. 4920316_1 (GHMatters) P72661.AU.3 - 12 Gaming systems for implementing games that involve a display of spinning reels as part of the display of the outcome of a game have either a video display or a mechanical display, these later machines most usually 5 being "stepper" machines which have a separate motor for each reel. However, persons skilled in the art will appreciate that the invention can be implemented in respect if other forms of games, including: card games; ball draw games (e.g. bingo or keno); dice games; and pin 10 and ball games. In some implementations the game controllers of such gaming machines select symbols by employing a stop determining function that randomly determines the stop 15 position for each reel. For example, if there are five reels, each having twenty symbols, the stop determining function might determine that the stop positions are positions: 3, 13, 7, 9 and 17. The spinning of the reels is then controlled so that each symbol comes to a stop in 20 the same row, typically a predetermined row in a "window" visible to the player on the display that which corresponds to a player playing a single win line. When a reel stops, the symbols will be in one of a plurality of possible symbol positions for that reel relative to the 25 stop position. Spinning reel type games typically allow a player to select how many win lines of a plurality of win lines they will play in each game - i.e. a minimum of one win line up 30 to the maximum number of win lines allowed by the game. Persons, skilled in the art, will appreciate that in other embodiments, the player may select a number of reels to play. Each win line is formed by a set of symbol positions consisting of one symbol position from each reel. That 35 is, a predetermined symbol position of each reel is assigned to a win line. The symbol positions that constitute each of the win lines are usually advertised to 4920316_1 (GHMatters) P72661.AU.3 - 13 the player by markings on the display or diagrams showing the symbol positions that correspond to each win line. Some of the win lines will be horizontal or diagonal lines but others may be non-linear combinations of symbols. 5 Typically, the win lines will be constituted by symbol positions in the visible window. A game outcome is determined based on the symbols on the win lines and a prize table that specifies awards. 10 The game controller 60 of the embodiment is shown in more detail in Figure 6. It will apparent that the processor 62 implements a number of modules, namely random number generator module 621, symbol selector module 622, outcome determiner module 623, award determiner module 624, 15 sequence monitoring module 625, entitlement module 627 and display controller module 626 based on data stored in memory 64. Persons skilled in the art will appreciate that not all modules need be implemented by processor 62. For example, the random number generator module 621 could 20 be implemented by a separate circuit or by a random number generator server. In the embodiment, the entitlement module 627 determines when a player is entitled to a feature game comprising a 25 sequence of games and initiates the feature. In other embodiments a player may be entitled to a single subsequent game. In this game, the subsequent game sequence is started by the symbol occurring in the base game, or a location where a particular symbol occurs in 30 the base game sets a position for a subsequent game, so that if there is a designated symbol combination on a game outcome in the subsequent game that includes the position where the particular symbol occurred in the base game then the award is made. In a particular example, the player is 35 entitled a subsequent game (which may or may not be a feature game) when a designated symbol combination occurs in the base game. For example, a combination of three 4920316_1 (GHMatters) P72661.AU.3 - 14 scatter symbols. In the sequence of subsequent or feature games the positions occupied by the symbols when the feature was triggered become particular locations to which special prize awards attach. 5 When the entitlement is established, the entitlement module 627 instructs the sequence monitor 625 to initiate a feature game having a sequence of games based on a number of games specified in sequence data 643. The 10 sequence monitor 625 is arranged to keep track of the sequence to ensure that all games of the sequence are carried out accordingly after each game in the sequence, and the sequence monitor 625 updates the sequence data 643 to indicate how many games remain in the sequence. 15 During each game of a sequence, the symbol selector 622 selects the symbols to appear based on symbol data 641 which specifies the available symbols. The symbols are selected by the symbol selector using a random number 20 obtained from the random number generator 621. The outcome determiner module 623 determines the game outcomes. The award pay scale adjuster 624 then adjusts an award for outcomes using pay scale data 644. The adjustment is based on the number of win lines the player 25 is playing and the symbol combinations. Persons skilled in the art will also appreciate that the game outcomes and their associated prizes are displayed on the display 54 or under control of the display controller 626. 30 The method 700 of an example of an embodiment of the invention is summarised in Figure 7. At step 710 it is determined game sequence should commence. The game controller 60 then carries out a sequence of initial games 720, provides locations 730 from which initial game 35 outcomes can be determined by symbols occurring at the locations, allocates at least one symbol as a trigger symbol 740, determines if a trigger symbol appears 750 4920316_1 (GHMatters) P72661.AU.3 - 15 which will trigger a feature game 760, and determines if a winning outcome occurs in feature game at 770 if there is a feature game outcome that includes the particular location where there has been the occurrence of the 5 trigger symbol, and provides an award allocation in the feature game at 780. If an award winning combination then occurs with one of the symbols occurring at the particular location, then the 10 award is increased. One or more particular locations can be nominated in any of the usual ways such as: - By outcomes on a machine 15 - At random - By player selection - Specified by rules of the game - Variable due to bets placed 20 The number of particular locations can be determined by the usual ways such as: - Specified by the rules of the game - Variable due to bets placed - Variable due to outcomes 25 The award can be increased in the usual ways such as: - Multiply the advertised value - Pay an additional bonus prize - Award an additional feature game 30 A feature game is triggered by a certain symbol combination. The feature game is played with feature wins interacting with the locations which triggered the feature game. 35 1. 3 or more "scatters" in an initial game triggers the feature game 4920316_1 (GHMatters) P72661.AU.3 - 16 2. The particular locations of the "scatters" are "highlighted". 3. Free Games begin to play. 4. After each free game an evaluation is made. 5 5. Any game win outcome that passes through one or more of the "highlighted" locations is multiplied by 5. 6. If the "feature" is retriggered in the feature game then the new scatter locations are also highlighted. 7. The original trigger locations remain highlighted. 10 TABLE 1 3 scatter symbols appear on the reels in an initial game. This triggers the feature game and in the next 3 free games any winning combinations landing on those particular 15 locations are multiplied by 5. scat A K Q J 10 9 scat A K Q J 10 9 scat TABLE 2 The particular locations where the "scatter" symbol appear 20 are now highlighted .

Persons skilled in the art will appreciate that the above examples provide locations from which game outcomes can be 20 determined by symbols occurring at locations. At least one symbol is allocated as a trigger symbol. On the occurrence of the at least one trigger symbol at a location in an initial game there is triggering of a feature game. An award is then made in the feature game 25 if there is a game outcome that includes the particular location where the trigger signal appeared in the initial game. Should the trigger symbol occur at the particular location the feature game may not be triggered unless there is a concurrent occurrence of the trigger symbol at 30 one or more further locations. 4920316_1 (GHMatters) P72661.AU.3 - 18 Whilst the above example has been described in relation to a five reel spinning game with three win lines, the spinning wheels may be replaced with columns where the symbols selectively appear at particular columns and 5 wherein there is one or more win lines. Further, persons skilled in the art will appreciate that when the feature game is played, the occurrence of an outcome can occur not only in particular rows as indicated in the preferred example but across multiple rows according to known game 10 patterns. It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute an admission that the publication forms a part of the 15 common general knowledge in the art, in Australia or any other country.
