Figure 2 is a perspective view of a stand alone gaming 5 machine; Figure 3 is a block diagram of the functional components of a gaming machine; 10 Figure 4 is a schematic diagram of the functional components of a memory; Figure 5 is a schematic diagram of a network gaming system; 15 Figure 6 is a further block diagram of a gaming system; Figure 7A - 7D are exemplary displays of a first example; 20 Figure 8A - 8B are exemplary displays of a second example; Figure 9 is a flow chart showing a method of one embodiment; and 25 Figure 10 is a flow chart showing a method of another embodiment. Detailed Description 30 Referring to the drawings, there is shown a gaming system having a game controller arranged to implement a game where an rotating object with a changing axis of rotation is used to display a win outcome modifier when . In an embodiment, the object is a multiplier ball having a 35 plurality of different multipliers thereon. The modifier that applies is that modifier that is displayed when the ball stops. In an embodiment, the multipliers at intervals 3223131_1 (GHMatters) P74138.AU.2 25/09/12 -9 around the surface in regions whose sizes are based at least partly on the value of the modifier. The gaming system can take a number of different forms. 5 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 10 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 15 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 20 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 25 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 30 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. 35 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 322313 1I (GHMatters) P74138.AU.2 25/09/12 - 10 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 5 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 10 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. 15 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 20 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 25 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 10 is illustrated in Figure 2. The gaming machine 30 10 includes a console 12 having a display 14 on which are displayed representations of a game 16 that can be played 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 35 game play. The mid-trim 20 also houses a credit input mechanism 24 which in this example includes a coin input chute 24A and a bill collector 24B. Other credit input 322313 I_ (GHMatters) P74138.AU.2 25109/12 - 11 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 5 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. A top box 26 may carry artwork 28, including for example 10 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 is from the gaming machine 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 20 crystal display, plasma screen, any other suitable video 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 25 type. It will be appreciated that the multiplier ball of the embodiment needs to be displayed on a video display, however, this could be on the main display 14 or a top box display. Hence, the multiplier ball could be used in combination with a main display 14 formed by an 30 electromechanical device, such as a set of stepper reels of a stepper gaming machine. Figure 3 shows a block diagram of operative components of a typical gaming machine which may be the same as or 35 different to the gaming machine of Figure 2. The gaming machine 100 includes a game controller 101 3223131_1 (GHMatters) P7413BAU 2 25/09/12 - 12 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 5 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 io 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 is 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 20 random numbers includes pseudo-random numbers. 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, input 25 devices in the form of a touch screen and/or buttons 107, a card and/or ticket reader 108, a printer 109, a bill acceptor and/or coin input 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 30 as required for the specific implementation. For example, other input devices known in the art to enable someone to interact with an electronic device may be employed. In addition, the gaming machine 100 may include a 35 communications interface, for example a network card 112. The network card may, for example, send status information, accounting information or other information 3223131_1 (GHMatters) P74138.AU2 25/09/12 - 13 to a central controller, server or database and receive data or commands from the central controller, server or database. 5 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 103A typically temporarily holds program files for execution by the processor 102 and related data. The 10 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 integrity of which may be verified and/or authenticated by the processor 102 using protected code from the EPROM 103B 1 or elsewhere. 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 20 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 network 201, which for example may be an Ethernet network. 25 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 30 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. 35 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. 3223131_1 (GHMatters) P74138.AU.2 25/09/12 - 14 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. 5 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 10 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 is 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. 20 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 25 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 30 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 35 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 3223131_1 (GHMatters) P74138 AU 25/09/12 - 15 210 is provided to allow an administrator to run the network 201 and the devices connected to the network. The gaming system 200 may communicate with other gaming s 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 10 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 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 game servers could be provided to run different games or a single game server 20 may run a plurality of different games as required by the terminals. Persons skilled in the art will also appreciate that the method of the preferred embodiment could be embodied in 25 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 memory (for example, that could replace part of memory 103) or as a data signal (for example, by downloading it from a server). 30 A more detailed schematic view of a gaming system is shown in Figure 6 which shows that a number of modules are implemented by processor 62 based on program code stored in memory 64. Persons skilled in the art will appreciate 35 that other hardware/software implementations are possible. In Figure 6, a player plays the game by entering currency 3223131_1 (GHMatters) P74138 AU.2 25109/12 - 16 with the credit mechanism which is converted to credits by game controller 60 and stored as credit data 647. The credit data will be modified in accordance with game play and in particular by wager instructions input with the s game play mechanism 56 and the prizes evaluated by the prize evaluator 623. The exemplary gaming system illustrated in Figure 6 is off the type where an outcome generator generates game 10 outcomes by selecting symbols with a symbol selector 621 from symbol data 641 in accordance with a probability table based on a random number obtained from a random number generator 621. In an embodiment, the game may be a spinning reel game where the symbols are the symbols on a 15 plurality of reels. The prize outcomes are determined by the prize evaluator based on the player's win entitlement (which is based on the wager the player made) and the prize data 643. That is, certain game outcomes will be win outcomes for the player. 20 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 reel games, it is typical for the player's entitlement to 25 be affected by the amount they wager and selections they wake (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 up to the maximum number of lines allowed by the game 30 (noting that not all permutations of win lines may be available for selection. 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 players selection of pay lines and are 35 an inherent part of the win entitlement. Persons, skilled in the art, will appreciate that in other 3223131_1 (GHMatters) P74138 AU.2 25109/12 - 17 embodiments, the player may obtain a win entitlement by selecting a number of reels to play. Such games are marketed under the trade name "Reel Power" by Aristocrat Leisure Industries Pty Ltd. The selection of the reel 5 means that each symbol of the reel can be substituted for a symbol at one or more designated display positions. In other embodiments a player win entitlement may be defined by purchasing access to particular pay tables e.g. a first bet amount entitles the player to wins 10 including cherries and a second amount entitles them to wins including plums. The win entitlement is not always purchased - e.g. a series of free games may be awarded. A win outcome is determined based on the selected symbols is of a game outcome and a player's win entitlement and a pay table 643 that specifies awards. In embodiments of this invention, a win outcome is modified by a win outcome modifier if a modification 20 condition 648 is determined to be met by the modifier controller 624 , for example if the outcome generator 622 generates an outcome that includes a designated symbol or symbol combination. In an embodiment, a modifier may be determined each time a win outcome occurs. Modifiers may 25 be, for example, absolute values or multipliers. The modifiers may include modifiers that do not change the win outcome (particularly in embodiments where a modifier is always calculated). A modifier may be determined in a one stage or two stage process as described in further detail 30 below. Once the modifier is determined and displayed to the player, the prize evaluator 623 modifies the prize outcome and updates credit data 647. The player may redeem credits via the credit mechanism 52 or in other manners known in the art, for example by printing a ticket having 35 a face value corresponding to the number of credits that may be redeemed such that it can be taken to a cashier. 3223131_1 (GHMatters) P74138.AU-2 25/09112 - 18 In most embodiments of this invention, the modifiers are displayed by an object such a spherical ball which is displayed as rotating and having a changing axis of rotation-i.e. which changes at least once and typically 5 multiple times-until the object stops, whereafter the object controller controls the display such that the modifier selected by the modifier controller is apparent for example by highlighting the modifier that is to be applied. 10 In some embodiments, the object also moves by translation. This provides an advantageous way of displaying the modifier. Display of the object by display controller 625 is controlled by object controller 626 which controls the 15 movement of the object based on object data 644 and includes and axis changer 626A - i.e. part of the control is to change the axis of rotation. In an embodiment, a composite modifier may be applied. In 20 such an embodiment, a plurality of targets specified by target data 646 are displayed on display 54 and the object is displayed as moving by translation relative to the targets. Each target has an associated further modifier and a target is randomly selected by the modifier 25 controller such that the modifier on the object and the modifier on the target are combined to form a composite modifier which is applied by the prize evaluator 623. The further modifier may have the effect of adding to the object modifier, negating the object modifier (e.g. a zero 30 multiplier) or making no difference (e.g. a one times multiplier). It will be appreciated that in this embodiment, while the effect of the object, such as a ball, rotating around a changing axis is particularly advantageous, the object need not spin relative to the 35 target while providing the advantageous effect of the modifier being indicated partly by the object and partly by the target. 3854542_1 (GHManers) P74138.AU.2 14/1 1/12 - 19 Persons skilled in the art will appreciate that while it is described above that the modifiers of the target and object are determined independently, they could be 5 determine as a single modifier which is then split between the object and the target. Figure 9 summaries the method 900 of one embodiment. The method 900 involves generating 910 a game outcome and determining 920 whether it is a winning outcome. For 10 winning outcomes 930 it is determined whether to generate a modifier, for example, for specific outcomes. When a modifier is to be applied, the display is controlled 940 such that the object is displayed with a changing object of rotation. The displayed modifier modifies 950 the win i5 outcome. Figure 10 summaries the method 1000 of another embodiment. The method 1000 involves generating 910 a game outcome and determining 1020 whether it is a winning 20 outcome. For winning outcomes 1030 it is determined whether to generate a modifier, for example, for specific outcomes. When a modifier is to be applied, the display is controlled 1040 such that the object is displayed as moving relative to a plurality of targets. The displayed 25 modifier modifies 1050 the win outcome. Further features of the above methods will be apparent from the above description of the gaming system and the below examples. Persons skilled in the art will also 30 appreciate that the method 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 memory (for example, that could replace part of memory 103) or as a data signal (for example, by 35 downloading it from a server). Examples 3223131_1 (GHMatters) P74138.AU.2 25/09/12 - 20 Example 1 In a first example, shown the exemplary displays of figure 5 7A to 7D. The ball is initially displayed at rest in a first position 710A within an aperture 720. From this first display 700A, it will be seen that there are a plurality of different regions on the ball which correspond to different modifiers, which in these examples 10 are multipliers. The multipliers visible in Figure 7A are a x2 and a x50 multiplier. The shapes of the regions are not of particular importance, however, it is assistance if they can be distinguished by either borders or different colours designating different multipliers. i5 In Figure 7B there is shown a further display 700B where the ball is shown as spinning within the aperture 720 such that the multipliers cannot readily be perceived. The spinning is such that the axis of rotation changes at 20 least once. Figure 7C shows a further view where the ball has stopped at a stop position 710C with a 2x multiplier 715 at the centre of the ball to indicate that this is the multiplier 25 that will apply. In Figure 7D, it is shown that the object controller controls the display of the object to further highlight that the x2 multiplier 715 applies by narrowing the 30 aperture 720A and highlighting 725 the x2 multiplier. Example 2 In the second example, the multiplier ball 830 is 35 displayed as moving by spinning and translating behind a screen 805 which has a number of slots therein 810 to 815 which provide a six different target 810 to 815 associated 322313 1_1 (GIHMatters) P741 38.AU.2 25/09/12 - 21 with six different modifiers 820 to 825. From the modifiers shown in the exemplary display 800A, it is seen that the modifier can be a multiplier as indicated by items 820 to 822 or an alternative prize as indicated by 5 items 823 to 825 which correspond to different jackpot levels. That is, in this example, the prize can be modified by being replaced with a jackpot prize or supplemented by a jackpot prize. 10 Referring now to Figure 8B, it will be seen that the ball 830 has come to a stop position where the 2x multiplier 835 is displayed within slot 812 indicating that a total multiplier of x30 (i.e. 2x15) will apply to the prize and needs to be implemented by the prize evaluator 623. 15 It will be apparent that the roaming object in this example could also be a dice, a coin (with either win or no win) or any other object. A "no win" target could also be added- i.e. effectively a negating modifier. 20 It will also be apparent that this target embodiment can be employed with an object that does not spin - i.e. in a variant where the novel display effect is provided by combining a target having a first modifier and a moving 25 object having a second modifier from which a composite modifier is apparent on the display.
