Detailed Description An Embodiment of the Invention Referring to the drawings, there is shown a gaming system 30 arranged to implement a game where a player can participate in forming a reel strip used at least during part of the game. The gaming system can take a number of different forms. 35 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. 3153574_ 1 (GHMattcrs) P74443.AU.2 16/02/12 -9 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 5 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, 10 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 15 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 20 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, 25 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 30 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 35 instructions and play the game. Components of the player interface may vary from 3153574_1 (GHMaters) P74443.AU.2 16/02112 - 10 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, a game play mechanism 56 that enables a player to input game play 5 instructions (e.g. to place bets), and one or more speakers 58. The game controller 60 is in data communication with the player interface and typically includes a processor 62 10 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 15 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. 20 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 25 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 30 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 35 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 3153574_1 (GHMattcrs) P74443.AU.2 16/02/12 - 11 medium capable of being read by the reading device. A top box 26 may carry artwork 28, including for example pay tables and details of bonus awards and other s 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 10. 10 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 i5 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. 20 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. 25 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 30 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 35 including ensuring regulatory compliance and monitoring player credit, an input/output (I/0) interface 105 for communicating with peripheral devices of the gaming 3153574_1 (GHMatters) P74443.AU.2 16/02/12 - 12 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 5 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. 10 In the example shown in Figure 3, a player interface 120 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 15 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. 20 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 25 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 30 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 3s 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 3153574_1 (GHMatters) P74443.AU-2 16/02/12 - 13 or elsewhere. It is also possible for the operative components of the gaming machine 100 to be distributed, for example 5 input/output devices 106,107,108,109,110,111 to be provided remotely from the game controller 101. Figure 5 shows a gaming system 200 in accordance with an alternative embodiment. The gaming system 200 includes a 10 network 201, which for example may be an Ethernet network. 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 15 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. 20 One or more displays 204 may also be connected to the 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 25 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 30 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 35 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 3153574_I (GHManers)P74443 AU 2 16102/12 - 14 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. 5 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, 10 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 is 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 20 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 25 network 201 and the devices connected to the network. 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, 30 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 35 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 3153574_1 (GHMatters) P74443.AU.2 16102/12 - 15 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 5 provided to run different games or a single game server may run a plurality of different games as required by the terminals. With reference to Figure 6 display 16 of the gaming 10 machine is shown which is a display showing virtual reels 16a, 16b, 16c, 16d and 16e. The display also has three lines or rows 50a, 50b and 50c. Thus, the display is typically a three by five virtual reel display in which the symbols in the reel 16a shown in Figure 16 form a 15 portion of a reel strip of the reel 16a. Typically, each reel strip will be made up of a number of symbols which may be anywhere from 20 to 200 or more and typically only a portion, usually 3 of those symbols of each reel strip are displayed on the display 16. 20 In order to play the game the player will insert coins into the machine or other forms of payment. The player can also select whether the player plays all lines 50a to 50c of the display or just one or two of those lines. In 25 order to play the game, the reels 16a to 16e are spun and are stopped in turn to form a display of the symbols on the reel strips of each reel 16a to 16e such as is shown in Figure 6. Typically, in a virtual reel system as distinguished from a mechanical reel system, the reels are 30 made to spin by a graphic interface driver which selects images in response to a random number generator and displays them in sequence, for example, moving symbols downwardly on each of the reels 16a to 16e shown in Figure 6 to give the appearance of a spinning type motion and 35 then stops the reels so that three of the symbols on each of the reel strips associated with the reels 16a to 16e are displayed. 3 153574_1 (GI-Matters) P74443 AU 2 16102/12 - 16 A win is determined based on the rules of the game which may comprise, for example, whether there is a predetermined number of the same symbol in a particular 5 row or line. For example, if there are two aces, a pay out to the player may result, and if there are three aces a greater payout may result etc. In accordance with the embodiment of the present invention 10 the player has the option of forming his or her own reel by making a selection of symbols. The player may be provided with this option in response to advancing to a particular level in a game such as a feature game, a particular payment made by the player such as an ante bet, 15 or any other stimulus which may be used as a basis for determining that a player can now make his or her own reel. Alternatively, the player may be given the option at the start of the game to make his or her own reel. In this embodiment, the player made reel may not be active at 20 all times. For example, the player made reel may only be active during a feature game even though specified at the beginning of a game session. The player's reel may remain active for an entire game session, for example until the gaming machine is inactive for a defined period or until a 25 player's loyalty card is removed. Further, in some embodiments, the player may make a plurality of reels or the players selections may be incorporated into all of the reels as described in further detail below. 30 As shown in Figure 7 at the beginning of a game session, a set of player selectable symbols 51 is randomly generated by selection from a source set of symbols and displayed on the display 16 either in place of the display shown in Figure 6 or merely as an overlay on the display shown in 35 Figure 6 or on another portion of the display 16 not occupied by the reels 16a to 16e. 3153574_1 (GHMaters) P74443.AU.2 16/02/12 - 17 One of the reels shown in Figure 6 is pre-programmed to be the reel where it is displayed to the player that they are adding symbols to make their player's reel. In one example, this is because this is the only reel which can 5 be made by the player and in this embodiment the reel 16c for example In other embodiments, the player may select which reel to make for example by paying for a specific reel. In still other embodiments, the added symbols may be added to each reel. In such an embodiment, the symbols to 10 be used when the my reel function is active can be displayed separately to the reels 16. In this embodiment, the user therefore selects one of the symbols from Figure 7 such as the symbol PIC 1 and that is symbol is located into the reel 16c in place of one of the symbols already present on the reel. The symbol PIC 1 need not necessarily form part of the display shown in Figure 6 and simply could be allocated to another portion of the reel strip of the reel 16c, not visible in the 20 display portion of the reel strip 16c shown in Figure 6. Further, the selected symbols need not necessarily replace symbols of the existing reel strip but can be added to the reel strip. For example, if the reel has 22 symbols, and the added symbols may be appended after the twenty-second 25 symbol. In one advantageous embodiment, five symbols are appended to the reel strip. Advantageously, the same five symbols can be added to each reel strip. A new group of symbols is then provided to the player by 30 being randomly generated and is shown in Figure 9. Again the player selects one of those symbols and that symbol is inserted into the reel strip of reel 16c. In this case the ace has been selected and is located into the reel strip of the reel 16c as shown in Figure 8. 35 As is shown in Figure 10, 11 and 12, further sets of symbols are then displayed and the user selects one symbol 3153574_1 (GHMans) P74443.AU.2 16/02/12 - 18 from each set for insertion into the reel strip of the reel 16c shown in Figure 5. In alternative embodiments the above process may continue 5 until a complete reel strip is formed in which all of the symbols on the reel strip are symbols selected by the player. Alternatively, the selected symbols may only comprise a portion of the reel strip or be appended to the reel strip. 10 The sets of symbols shown in Figures 7 and Figure 9 to 12 may be generated in a number of different ways. In a first embodiment the symbols are merely randomly generated and are selected by a random number generator. In other 15 embodiments, various pathways (or rules) may be programmed into the machine for selection of the sets of symbols depending on the amount wagered by the player, the status of the game (that is whether the player has a reach a predetermined level in the game) or otherwise to control 20 the likelihood of a player win using the player selected symbols. When it is determined, that the player's reel is to be active, for example, when a feature game is triggered, the 25 reels 16a to 16e are again spun and are stopped in turn so that the three lines 50a, 50b and 50c are displayed. Again the programme of the game determines whether there is a win from the displayed symbols and also based on the row or lines the player is playing. 30 In another embodiment, rather than locating the selected symbols into or appending them to an already formed reel strip, a blank reel strip may be provided as one of the reels 16a to 16e and the blank reel strip is filled in by 35 the selected symbols from the sets of symbols shown in Figures 7 and Figures 9 to 12. 3153574_1 (GHMatters) P74443.AU.2 16/02/12 - 19 Figures 13 and 14 show a flowchart and functional modular diagram relating to the embodiment of the invention. The flow chart assumes that the player's generated reel strip is active. Persons skilled in the art will appreciate that 5 a display 16 is formed in response to a player initiating 1305 a play or spin 88 of the reels. In response to which the spin module 88, spins 1325 causes the selection of a stopping position for each reel. Typically, the symbols have defined sequence in a reel strip and a reel stop 10 module 80 employs a random number generator selects a stopping position for the reel strips as specified by reel strip data 90 to form the displayed portions reel strips of the reel 16a to 16e. is The sets of user selectable symbols 51 are generated 1315 by selectable symbol module 81 using a random number generator under the control of the "form my reel" functional module 82 which identifies whether a reel is to be formed 1310 based on the eligibility requirements, for 20 example based on reaching a stage in the game, such as feature game or in response to user input with a particular payment, or other stimuli. The random number generator 82 generates 1315 the various sets of symbols so that the user can select from those sets by input 1320 to 25 module 85 to make the selection from each displayed set. This may be done by way of a touch screen where the user simply touches the symbol the user wishes to select, or pressing a button, keyboard entry or otherwise. Once the selection is made functional module 86 adds or appends 30 that symbol into one of the reel strips and this is stored as reel strip data 90. In embodiments, where the player's reel is not always active, reel strip controller controls which reels are to be used at any time 87. For example, in an embodiment where the player selected symbols are 35 appended to the end of each reel strip during free spins .in a triggered feature game. 3153574_1 (GHMatters) P74443.AU.2 16/02/12 - 20 If the sets of symbols 51 are to be formed by a particular pathway rather than randomly, module 86 may be used to select the symbols based on the predetermined rules for the pathway or the module 87 may modify the selection 5 generated by the random number generator 81. Once the reel has been formed by the player and is to be used in a spin, the reels are spun 1325 at module 88 and are stopped in sequence and the reels are evaluated 1330 10 to see of there is a win at module 89 before the win is ultimately paid 1335. Since modifications within the spirit and scope of the invention may readily be effected by persons skilled is within the art, it is to be understood that this invention is not limited to the particular embodiment described by way of example hereinabove.
