Brief Description of Drawings An exemplary embodiment of the invention will now be described 30 with reference to the accompanying drawings in which: Figure 1 is a block diagram of the core components of a gaming device; 35 Figure 2 is a perspective view of a stand alone gaming device; Figure 3 is a block diagram of the functional components of a gaming device; 40 Figure 4 is a schematic diagram of the functional components of a memory; Figure 5 is a schematic diagram of a gaming system; 2024204540   30 Jun 2024 Figure 6 is a block diagram of a gaming system; 5 Figure 7 is a block diagram of a gaming system; Figure 8 is a flow chart of an embodiment; and Figure 9 is a flow chart of an embodiment. 10 Detailed Description Referring to the drawings, there is shown a gaming device having a game controller configured to employ one of a 15 plurality of game state identifiers associated with respective ones of a plurality of game states to enable a game to be restored or to restore a game. Advantageously, the game state identifiers allow the game controller to easily duplicate game states when enabling a game to be restored. This allows 20 players to restore a game at a later time, for example, to access game features previously unlocked in the game. In certain embodiments, the gaming device is provided as part of a gaming system, where the game controller also relies on a 25 session identifier from a session server. The session identifier provides a simple yet effective way of controlling the number of times a game may be restored, typically so it can only be restored once. 30 It is envisaged that a game state corresponds to a particular stage of a game. Persons skilled in the art will appreciate that a game state need not correspond only to the end or beginning of a stage of a game and that a game state may correspond to any point of a game. For example, a game state 35 may correspond to the middle of a game stage where a new game feature is unlocked. It is envisaged that a predetermined plurality of game state identifiers are associated with respective ones of the 40 plurality of game states. It is envisaged that each game state is associated with a game state identifier by a game state 2024204540   30 Jun 2024 mapper configured to map the game state to the game state identifier. Persons skilled in the art will appreciate that the game state mapper may be implemented by a processor of a computer based on computer program code stored in a memory or 5 other tangible storage medium. Herein the term "processor" is used to refer generically to any device that can process game instructions and may include: a microprocessor, microcontroller, programmable logic device or other computational device, a general purpose computer (for example, 10 a PC) or a server. General construction of the gaining device In an embodiment, the gaming device is a stand alone gaming 15 machine wherein all or most components required for enabling restoration of games or for restoring games are present in a player operable gaming machine. The gaming device has several core components. At the broadest 20 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 device and for this purpose includes the input / output components required for the player to enter 25 instructions to play a game, observe game outcomes, to enable restoration of a game, or to restore a game. Components of the player interface may vary from embodiment to embodiment but will typically include a credit mechanism 52 to 30 enable a player to input credits and receive payouts, one or more displays 54, a game play mechanism 56 including one or more input devices that enable a player to input game play instructions (e.g. to enable a player to input / output instructions for enabling the restoration of a game or for 35 restoring a game), and one or more speakers 58. 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 40 play rules and outputs game play outcomes to the display. 2024204540   30 Jun 2024 Typically, the game play rules are stored as program code in a memory 64 but can also be hardwired. As discussed earlier, a "processor" may be any device that may be arranged or configured to process game play instructions in accordance 5 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 device 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 by a player. Although not illustrated, the gaming machine also includes 15 readers / printers for a player to insert a ticket and / or to retrieve a ticket printed by the gaming machine, a keypad for a player to enter game restoration information and a transmitter for sending out game restoration information. A mid-trim 20 of the gaming machine 10 houses a bank of buttons 20  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 chute 24A and a bill collector 24B. Other credit input mechanisms may also be employed, for example, a card 25 reader for reading a smart card, debit card or credit card. 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 30 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. The display 14 shown in Figure 2 is in the form of a video 35 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 display unit, or the visible portion of an electromechanical device. The top box 26 may also include a display, for example a video display 40 unit, which may be of the same type as the display 14, or of a 2024204540   30 Jun 2024 different type. Figure 3 shows a block diagram of operative components of a typical gaming machine which may be the same as or different 5 to the gaming machine of Figure 2. The gaming machine 100 includes a game controller 101 having a processor 102 mounted on a circuit board. Instructions and data to control operation of the processor 102 are stored in a 10 memory 103, which is in data communication with the processor 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. 15 The gaming machine has hardware meters 104 for 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 20 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 devices. A random number generator module 113 generates random numbers for use by the 25 processor 102. Persons skilled in the art will appreciate that the reference to random numbers includes pseudo-random numbers . In the example shown in Figure 3, a player interface 120 30 includes game restoration devices that communicate with the game controller 101. These include a ticket printer 109, a ticket reader 108, an identifier transmitter 114 and a keypad 115. In addition, the player interface also comprise peripheral devices including one or more displays 106, a touch 35 screen and / or buttons 107 (which provide a game play mechanism), 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 as required for the specific implementation. For 40 example, while buttons or touch screens are typically used in 2024204540   30 Jun 2024 gaming machines to 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. 5 In addition, the gaming machine 100 may include a communications interface, for example a network card 112. The network card may, for example, send requests for information or other information to a session server and receive requests for information or other information from a session server. 10 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 15  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 integrity of which may be verified and / or authenticated by the processor 102 using protected code from the EPROM 103B or 20 elsewhere. General construction of the gaming device as part of a gaming system 25 In another embodiment, the gaming device is part of a gaming system wherein some of the components required for enabling restoration of games or restoring games are present in a player operable gaming machine and some of the components required for implementing the game are located remotely 30 relative to the gaming machine. For example, some of the steps for enabling the restoration of a game may be executed on a player operable gaming machine and some of the steps for restoring a game may be executed remotely by a session server. 35 In addition, it will be understood that other arrangements are envisaged. For example, a gaming system may be provided wherein a gaming machine is networked to a session server and the respective functions of the gaming machine and the gaming server are selectively modifiable. For example, the gaming 40 machine, although part of the gaming system, may operate in 2024204540   30 Jun 2024 stand alone gaming machine mode depending on the game being played, operating conditions, and so on. Other variations will be apparent to persons skilled in the art. 5 Figure 5 shows a gaming system 200 in accordance with an embodiment. The gaming system 200 includes a network 201, which for example may be an Ethernet network. Gaming machines 202A,202B,202C in Figure 5 are connected to the network 201. The gaming machines 202A,202B,202C each provide a player 10 operable interface and may be the same as the gaming machines 10,100 shown in Figures 2 and 3, or may have simplified functionality depending on the requirements for enabling restoration of games and for restoring games. While gaming machines 202A,202B,202C are illustrated as being individually 15 connected to the network 201, banks of two or more gaming machines are also envisaged. In Figure 5, there is also illustrated a session server 206 for administering session identifiers that are stored in a 20 database 207. As discussed earlier, these session identifiers may be used together with the game state identifiers to enable the restoration of a game or to restore a game played in any one of the gaming machines 202A,202B,202C. In Figure 5, the session server 206 is illustrated as a central server that 25 communicates with all of the gaming machines 202A,202B,202C. 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 30 example through a firewall 211. Persons skilled in the art will appreciate that in accordance with known techniques, the session server 206 need not be centralized and that the functionality at the server side of 35 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. That is, the session server can be implemented in a distributed fashion wherein the gaming machines are connected 40 to separate session servers each of which is able to 2024204540   30 Jun 2024 communicate with the database 207. It is also envisaged that the database 207 itself may be implemented in a distributed fashion. For example, a central session server 206 can communicate with multiple databases so that some of the 5 session identifiers are stored in one database and the other session identifiers are stored in another database. Further detail of the gaining system 10 Figure 6 illustrates, in an embodiment, the game controller of a gaming device. In Figure 6, the game controller 60 is shown implementing a number of modules to enable the restoration of a game. Persons skilled in the art will appreciate that the modules are based typically on program code 641 and data 15 stored in memory 64. Persons skilled in the art will also appreciate that the modules are implemented typically using processor 62 but that some of the modules could be implemented in some other way, for example by a dedicated circuit. 20 In Figure 6, the modules include a restoration request receiver 310 which operates in response to a player's operation of player interface 50 by having the player operate an input device 56 (e.g. pressing the touch screen and / or one of more buttons) to receive a request for subsequent 25 restoration of a game. The restoration request receiver 310 is also arranged to communicate the request for subsequent restoration of a game to a session identifier requestor 320 and a game state identifier selector 340. The session identifier requestor 320 is arranged to make a request for a 30 session identifier from a session server 306. In an embodiment, this request for a session identifier can be transmitted through a network via a network card of a gaming device. The session server 306 is arranged to receive this request. A session identifier generator 370 is arranged to 35 generate a session identifier. Persons skilled in the art would appreciate that this can be done in a variety of ways (for example by generating a pseudo-random number sequence) and that the session identifier can be of a variety of lengths (for example, a 16 bit sequence) and / or be in different format 40 (for example, a hexadecimal sequence). The session server 306 2024204540   30 Jun 2024 is arranged to output the session identifier upon receiving this request to a session identifier issuer 330. The session generator 306 is also arranged to transmit the newly generated session identifier to a session identifier database 380 to 5 update the database. The session identifier database 380 is arranged to store the session identifiers that have been issued. The session identifier issuer 330 is arranged to issue the session identifier to the player interface 50. 10 The game state identifier selector 340 is arranged to select one of a plurality of game state identifiers associated with respective ones of a plurality of game states based on the current game state presented at the gaming device. In this embodiment, the game state identifier selector 340 is arranged 15 to select a game state identifier from a game state identifier database 360. The game state identifier database 360 is arranged to store a predetermined set of game state identifiers corresponding to various game states. The game state identifier selector 340 is arranged so that the selected 20 game state identifier can be communicated to a game state issuer 350 which is arranged to issue the game state identifier to the player interface 50. The player interface 50 is arranged so that either the session 25 identifier or the game state identifier or both the session identifier and the game state identifier can be output to a user. In this embodiment, a ticket printer 309 is used to output the session identifier and / or the game state identifier by printing a ticket comprising either the session identifier 30 or the game state identifier or both the session identifier and the game state identifier. In an alternative embodiment, either or both the session identifier and / or the game state identifier can be output to a user by an identifier transmitter which transmits a Short Messaging Service (SMS) 35 message comprising either the session identifier or the game state identifier or both the session identifier and the game state identifier. Typically, users are output with both a game state identifier and a session identifier. 40 Figure 7 illustrates the game controller 60 implementing a set 2024204540   30 Jun 2024 of modules to restore a game. As with Figure 6, persons skilled in the art will appreciate that the modules are typically implemented by processor 62 based on program code 642 stored in memory 64 but that some of the modules could be 5 implemented in some other way, for example by a dedicated circuit. The modules include a game state identifier receiver 410 arranged to receive a game state identifier from the player 10 interface 50. In this embodiment, a game state identifier is received when a player inserts a ticket comprising the game state identifier into a ticket reader 408. Alternatively, a game state identifier may be received when a player enters the game state identifier on one of the input devices 56 of the 15 gaming device (e.g. by entering the game state identifier on a keypad). Person skilled in the art will appreciate that an input device can be used in various ways so as to allow a game state identifier to be received; for example, a "virtual" keypad on the touch screen of the gaming device can be used to 20 enter the game state identifier. The modules of the game controller 60 also include a session identifier receiver 420 arranged to receive a session identifier from the player interface 50. In this embodiment, a 25 session identifier is received when a player inserts a ticket comprising the session identifier into the ticket reader 408. It is envisaged that a ticket can comprise either the game state identifier or the session identifier or both the session identifier and the game state identifier. In an alternative 30 embodiment, the session identifier can be received when a player enters the session identifier using one of the input devices 56. It is envisaged that a player may enter a game state identifier (or a session identifier) using one of the input devices 56 but use a ticket to provide the session 35 identifier (or game state identifier). The session identifier receiver 420 is arranged so that the session identifier received from the player interface 50 may be communicated to the session identifier communicator 430 so 40 as to determine whether the session identifier received from 2024204540   30 Jun 2024 the player interface 50 has been previously used to restore a game. In an embodiment, this communication is transmitted through a network via the network card. In this embodiment, a session identifier verifier 470 is arranged to determine 5 whether the session identifier received from the player interface 50 has been previously used to restore a game by searching through a session identifier database 480 which stores the session identifiers that have been issued by not previously used to restore a game. The session identifier 10 communicator 430 is arranged so that the result of this determination can be communicated to a game state restorer 440. Person skilled in the art will appreciate that the determination of whether the session identifier received from the player interface 50 has been previously used to restore a 15 game can also be done in a variety of ways and can depend on how the session identifier was issued. The session identifier communicator 430 is also arranged to communicate to the game state restorer 440 that an otherwise invalid session identifier was received from the player interface 50. In this 20 embodiment, once the session identifier verifier 470 determines that the session identifier from the player interface 50 has not been previously used to restore a game, it deletes the session identifier listed in the session identifier database 480 so that the same session identifier 25 cannot be used in the future to restore another game. Persons skilled in the art would appreciate that the session identifier verifier need not always restrict each session identifier to be used only once. For example, each session identifier stored in the session identifier database can be 30 associated with a count value that is decremented each time a session identifier is used to restore a game. In this way, each session identifier can be used to restore a game a plurality of times instead of just once. 35 The game state restorer 440 is arranged to restore a game at the gaming device to one of a plurality of game states associated with respective ones of a plurality of game state identifiers based on the game state identifier communicated from the game state identifier receiver 410 if the game state 40 restorer 440 receives from the session identifier communicator 2024204540   30 Jun 2024 430 the determination that the session identifier has not yet been used and is otherwise valid. In this embodiment, the game state restorer 440 is arranged to restore a game by restoring the game to the game state that is associated with the game 5 state identifier communicated from the game state identifier receiver 410. Persons skilled in the art will appreciate that a game controller will typically implement not only the modules of 10 Figure 6 but also the modules of Figure 7. Accordingly, a game controller may be used both to enable restoration of games and to restore games. The method of enabling restoration of games is outlined in 15 Figure 8. First, a request for enabling restoration of a game is received at a gaming device 810. This request may be initiated by a player using a touch screen and / or buttons of the gaming device during play of a game. After the request is received, one of a plurality of game state identifiers (each 20 associated with a respective one of plurality of game states) is selected based on the game state currently being presented at the gaming device 820. A request for a session identifier from the session server is also made 830 after the request for enabling restoration is received. After a session identifier 25 is received from the session server 840, the selected game state identifier and the received session identifier is then issued 850 and a ticket printer prints a ticket comprising the game identifier and session identifier. Once the game state identifier is printed, the game presented at gaming machine is 30 stopped and a database is updated to reflect that the particular session identifier has been issued. Person skilled in the art will appreciate that the game identifier and / or session identifier can be issued in other 35 ways. For example, the session identifier can be issued by requesting the player to enter his / her mobile phone number on the keypad of a gaming device that is connected via a network to a SMS Gateway and transmitting from the SMS Gateway a Short Messaging Service (SMS) message comprising the game identifier 40 and / or session identifier to the player's mobile phone, where 2024204540   30 Jun 2024 it will be stored in a memory of the phone. It is also envisaged that a player may input player information (such as a player's loyalty membership details) 5 via a keypad, touch screen and / or buttons to register the ticket before or after the ticket is printed by a ticket printer so that the player can restore a game even if he has lost the ticket. 10 Additionally, the ticket, game state identifier and / or session identifier may also be associated with a pin or password so that only the player is able to use the ticket, game state identifier and / or session identifier. 15 The method of restoring games corresponding to the above method of enabling restoration of games is illustrated in Figure 9. A game state identifier is first received at a gaming device 900. This game state identifier can be received by having a player enter the game state identifier manually 20 using a keypad of the gaming device or by having the player insert a valid ticket into the ticket reader of the gaming device. Next a session identifier is received 910. The session identifier can also be received via the keypad or the ticket reader of the gaming device. This can involve entering player 25 information (if the player lost his ticket) and / or entering a pin or associated password using the keypad, touch screen and / or buttons. Both the game state identifier and the session identifier can be received simultaneously or one can be received before the other. The session identifier is then 30 communicated to a session server 920. Upon receiving this communication, a determination as to whether the session identifier was previously used to restore a game is made 930. It is envisaged that the session identifier or the game state identifier may also be validated before this determination is 35 carried out. If it is determined that the session identifier was previously used or either or both the session identifier or the game state identifier are invalid identifiers, the gaming device reverts back to the state of waiting to receive a game state identifier. If it is determined that the session 40 identifier was not previously used and that both the game 2024204540   30 Jun 2024 state identifier and the session identifier are valid, the gaming device then proceed to restore a game to one of the plurality of game states based on the game state identifier 940. 5 Further aspects of the method will be apparent from the above description of the gaming system. Persons skilled in the art will also appreciate that the method could be embodied in program code. The program code could be supplied in a number 10 of ways, for example on a tangible 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 transmitting it from a server). 15 Similarly, it will be appreciated that the identifiers can be supplied on any appropriate tangible data carrier, such as by writing them to a magnetic swipe card, storing them in a memory (including transmitting identifiers to a device having a memory) etc. 20 It will be understood to persons skilled in the art of the invention that many modifications may be made without departing from the spirit and scope of the invention, in particular it will be apparent that certain features of 25 embodiments of the invention can be employed to form further embodiments . It is to be understood that, if any prior art is referred to herein, such reference does not constitute an admission that 30 the prior art forms a part of the common general knowledge in the art in any country. In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due 35 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 not to preclude the presence or addition of further features in various embodiments of the 4 0   invention.
