The clues are intended to assist the player in playing of a secondary game. In an alternative embodiment, pieces of a set of pieces intended to be redeemed for a prize are 10 issued to a player instead of clues. The gaming system can take a number of different forms. In a first form, a stand alone gaming machine is provided wherein all or most components required for implementing 15 the game are present in a player operable gaming machine. 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 20 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, 25 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 30 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 35 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 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 5 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. 5 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 60 as illustrated in Figure 1. The player interface is 10 arranged to enable interaction between a player and the gaming system and for this purpose includes the input/output components required for the player to enter instructions and play the game. 15 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 and receive payouts, one or more displays 54 and a game play mechanism 56 that enables a player to input game play 20 instructions. 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 25 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 to any device that can process game play instructions in 30 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. 35 The gaming system of the embodiment includes a clue entitlement mechanism for determining whether a player is entitled to be issued a clue based on the player's game 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 6 play activity in relation to at least one primary game and a clue issuer for issuing the clue to the player. Persons skilled in the art will appreciate that in some embodiments there may be a plurality of different primary 5 games from which a player may obtain clues. Indeed, in some embodiments different clues for the same secondary game may be available from different games. Persons skilled in the art will also appreciate that the clue entitlement mechanism and clue issuer can take a number of 10 different forms; the two main forms are illustrated in Figures 6 and 7. In Figure 6, the clue issuer 66 is a component of the game controller 60 and incorporates the clue entitlement 15 mechanism 67. The clue entitlement mechanism 67 monitors game play activity and determines whether a player has become entitled to a clue based on their game play activity. When the clue entitlement mechanism 67 determines that a player has become entitled to a clue, 20 the clue issuer 66 sends a clue to the clue output mechanism 58. The clue output mechanism 58 may take a number of forms, for example, a display for displaying a message, a ticket issuer, or a write mechanism for writing data to a player tracking device. 25 The other main form of a gaming system including a clue issuer 70 is illustrated in Figure 7. In this form, the clue issuer 70 is provided as a separate component to the clue entitlement mechanism 67. In this embodiment, clue 30 entitlement mechanism 67 determines whether a player is entitled to a clue and, if it does, it controls clue entitlement output 59 to output a clue entitlement to the player in the form of a message, a ticket, data to a player tracking device, etc. The player then subsequently 35 retrieves the clue by providing the clue entitlement to a clue entitlement input 72 of a clue issuer 70. The clue issuer 70 incorporates a clue output mechanism 74 for 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 7 outputting the clue to a player as described in relation to Figure 6, the clue output mechanism 74 may be a display, a printer or configured to output data sent to the player's player tracking device. In an embodiment, as 5 described in further detail below, the clue issuer 70 may form part of a gaming machine arranged to play the secondary game and it may issue clues during play of the secondary game. 10 The game play activity used as the basis of determining the entitlement can be, for example, turnover on the gaming machine, the outcome of a game or a feature game, time, a machine related event, or an event related to a system to which the machine is connected. Persons skilled 15 in the art will appreciate that the clue entitlement mechanism will be configured to respond to the relevant game play activity. For example, in the case of turnover, the clue entitlement mechanism 67 may incorporate a meter for monitoring turnover and issuing of a clue entitlement 20 based on a threshold being passed. Similarly, if time is measured, the clue entitlement mechanism 67 may incorporate a timer for monitoring expired time. As described above, a clue can be delivered to a player by 25 one of many methods, including but not limited to a ticket printed by the gaming machine, a message on the machine, a message on a piece of auxiliary equipment, a ticket issued by an attendant or issued onto a player card and redeemed at a player information terminal, or issued on a player 30 tracking device, or redeemed during playing of another game. The delivery method may be adapted to suit the needs of the player, the regulators and the market in which the 35 gaming system is deployed. As in the example given in Figure 7, the clue entitlement 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 8 can be issued separately. For example, in the form of a message to "Call Mr Cashman on *** and use your PIN number ### to redeem your clue" or "Log into our website and use your PIN number ### to redeem your clue.". Clues can also 5 be delivered in other ways, for example by mail or messenger. In any embodiment where there is an interim step between determining that the player is entitled to a clue and 10 redeeming of a clue, this is referred to as a clue entitlement. A clue entitlement can be issued by a machine that is then subsequently redeemed by a clue issuer. The clues obtained from the clue issuer will typically be downloaded to the clue issuing machine over a 15 network. For example a PIN number can be correlated to a specific clue held in the database. Alternatively, the clues are programmed into the game code software run on the gaming machine and released at times 20 to suit play of the secondary game. For example, a primary game can be designed to generate a set of different clue entitlements corresponding to different clues that may be released by a secondary game. A plurality of clue entitlements can be stored on a player 25 tracking device. The player supplies the player tracking device to a gaming machine when playing the secondary game and clues are supplied to the player at appropriate times during play of secondary game on the electronic gaming machine based on the entitlements stored in the player 30 tracking device. Persons skilled in the art will appreciate that the primary and secondary games could be played on the same gaming machine. That is, in some gaming systems, gaming machines are configured to allow a player to select which game they play on a particular 35 gaming machine. Alternatively, the secondary game could be a bonus or feature game. 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 9 The clue will be of the nature to enable the player to use the clue in the play of the secondary game. Preferably the chance of winning the secondary game is enhanced by having large numbers of different clues. Once the 5 secondary game is concluded, the previously issued clues will be redundant and a new set of clues that are required will become available. In some embodiments, the clues can be categorised into 10 different classes of clues. Different classes of clues can be found, for example in different types of machines or can be available from different games. For example, clues can be in the categories of time, place or person and the time clues are found on $1 machines, place clues 15 are found on 10c machines and person clues are found on 1c machines. In the embodiment, clues can only be used to play the secondary game. Ideally the secondary game is a game 20 which requires the player to use the clues acquired from the play of the primary game. Preferably, the clues are designed such that the player with the most clues will have a better chance of solving the special game and winning. Alternatively, some clues will have more "value" 25 than others and the player with the more favourable clues will have more chance of solving the second game. In another embodiment, the clues can provide a key or information to a player which enables the player to enter 30 a special feature or play a special game which has an enhanced player return. In another embodiment, the player receives clues from a gaming machine or preferably many gaming machines which, 35 with all clues in hand, can lead the player to some destination. At this destination, a "hidden treasure" can be retrieved which can subsequently be redeemed. By way 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 10 of example, clues may direct the player to a location, provide an instruction or a limit. A gaming system in the form of a stand alone gaming 5 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. Depending on the embodiment, display 14 may also be used to output clues or clue entitlements. A 10 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 and thus provide a game play mechanism. The mid-trim 20 also houses a credit input mechanism 24 which in this example 15 includes a coin input 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 read/write device (not shown) may also be provided for the purpose of reading and writing a 20 player tracking device, for example as part of a loyalty program or if clues or clue entitlements are to be issued to the player tracking device. 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 25 reading device. The player tracking device reader may be provided in player marketing module connected to the gaming machine and adapted to communicate with the gaming machine. 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. 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 11 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. In some embodiments, clues or clue entitlements may 10 be displayed on a top box video display. 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. A 20 subset of the instructions and data will relate to implementation of the game. The clue entitlement mechanism and clue issuer may be implemented as another subset of the instructions implemented by the processor. Alternatively, separate hardware may be provided for issue 25 clues and/or clue entitlements. For example, a circuit that monitors meters 104. 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. 30 The gaming machine has hardware meters 104 for purposes including ensuring regulatory compliance and monitoring player credit, an input/output (I/O) interface 105 for communicating with peripheral devices of the gaming 35 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 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 12 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 5 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, a touch 10 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. In some embodiments, ticket reader 108 may read clue entitlement tickets and printer 109 may print clues or clue 15 entitlements. Additional hardware may be included as part of the gaming machine 100, or hardware may be omitted as required for the specific implementation. In addition, the gaming machine 100 may include a 20 communications interface, for example a network card 112. The network card may, for example, send status information, accounting information or other information to a central controller, server or database and receive data or commands from the central controller, server or 25 database. Figure 4 shows a block diagram of the main components of an exemplary memory 103. The memory 103 includes RAM 103A, EPROM 103B and a mass storage device 103C. The RAM 30 103A typically temporarily holds program files for execution by the processor 102 and related data. The EPROM 103B may be a boot ROM device and/or may contain some system or game related code. The mass storage device 103C is typically used to store game programs, the 35 integrity of which may be verified and/or authenticated by the processor 102 using protected code from the EPROM 103B or elsewhere. 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 13 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 5 provided remotely from the game controller 101. Figures 8 and 9 show two possible implementations of a clue issuer and clue entitlement mechanism in a networked gaming environment. In Figure 8, an electronic gaming 10 machine 810 is used by a player to play a primary game, noting that there may be a plurality of eligible primary games from which clues are distributed. In order to obtain clues, the player enters a player ID using player ID input 812 of the electronic gaming machine 810. It is 15 envisaged that the player ID input would typically be a player tracking device reader of the gaming machine (or connected to the gaming machine) so that the player ID would be provided by supplying a player tracking device to the tracking device reader but it could also be a keypad, 20 touch screen or the like. The gaming machine 810 includes a clue entitlement mechanism 814 that determines that the player is entitled to a clue in the general manner described above. When the player is entitled to a clue the clue entitlement mechanism communicates the clue 25 entitlement to a player database where it is a stored in a player record 822 of a player database 820 containing a series of player records. A player may at some later time provide their player ID to clue issuer, for example in the form of a kiosk specially designed to issue clues. The 30 clue issuer 830, examines the player record 822 for the player corresponding to the player ID input using the player ID input 832, determines what clues the player is entitled to base on the clue entitlements stored in the player record and outputs the clues using clue output 35 mechanism 834. The clue output mechanism 834 can be in any of the forms described above including a ticket printer. 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 14 In the alternative arrangement of Figure 9, the player uses a first electronic gaming machine 910 to play a primary game. Before playing the primary game, the player 5 inputs their player ID using player ID input 912 in the manner described above. During play of the primary game, the electronic gaming machine 910 determines whether the player is entitled to a clue entitlement 914 and sends entitlement data to the player database which updates the 10 player record 922. In this embodiment, clues are issued to a player during play of a secondary game on a second electronic gaming machine 940 arranged for play of the secondary game. 15 Prior to playing the game, the player enters their ID using ID input 942, and clue issuer 944 determines based on the ID whether their associated player record 922 contains any clue entitlements required for the secondary game. The clue issuer 914 issues clues on the basis of 20 the player's clue entitlement during appropriate parts of play of the secondary game. It will be appreciated that in such networked embodiments, the player database may be implemented as part of an 25 existing loyalty program. At least in this embodiment, the clue entitlement may be combined with the player reward program. For example, if a player obtains a series of rewards based on turnover, these rewards may be redeemable for clues for use in the secondary game. In 30 this embodiment, the clue issuer is typically configured to allow the player to selectively redeem rewards for clues. In at least this embodiment, things other than game play that contribute to reward entitlements may thus contribute to clue entitlements, for example other 35 purchases made at a gaming venue. Figure 5 shows more detail of a gaming system 200 that 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 15 includes a 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 5 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 simplified functionality depending on the requirements for implementing game play. While banks 203 of two gaming machines are illustrated in Figure 5, banks 10 of one, three or more gaming machines are also envisaged. 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. 15 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. 20 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 the gaming machine implement part of the game, they 25 collectively provide a game controller. Thus, depending on the embodiment, the clue issuer or clue entitlement mechanism could be provided on the gaming machine or the game server or a combination thereof. A database management server 206 may manage storage of game programs 30 and associated data for downloading or access by the gaming devices 202 in a database 206A. Typically, if the gaming system 200 enables players to participate in a Jackpot game, a Jackpot server 207 will be provided to monitor and carry out accounting functions for the Jackpot 35 game. In a thin client embodiment, game server 205 implements 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 16 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. Hence, 5 the clue entitlement mechanism and/or clue issuer would typically be provided by the server with the gaming machine merely acting to output the clue or clue entitlements. The gaming machine will receive player instructions, pass these to the game server which will 10 process them and return game play outcomes to the gaming machine for display. In a thin client embodiment, the gaming machines could be computer terminals, e.g. PCs running software that provides a player interface operable using standard computer input and output components. 15 Servers are also typically provided to assist in the administration of the gaming system 200, including for example a gaming floor management server 208, and a licensing server 209 to monitor the use of licenses 20 relating to particular games. An administrator terminal 210 is provided to allow an administrator to run the network 201 and the devices connected to the network. Server 212 may implement a player rewards program where reward data is collected against a record identifying the 25 player. As described above, clue entitlements may be stored in, and retrieved from, the player's player record. The gaming network 200 may communicate with other gaming systems, other local networks, for example a corporate 30 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 accordance with known techniques, functionality at the 35 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 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 17 separate server may be provided. For example, the game server 205 could run a random generator engine. Alternatively, a separate random number generator server could be provided. Further, persons skilled in the art 5 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. 10 Figure 10 shows a variation on the above embodiments. In this embodiment, rather than clues being issued, a series of "pieces" are issued. Thus, instead of a clue issuer, the system includes a piece issuer and a piece entitlement mechanism 66A, 67A and a piece output mechanism 58A. The 15 technique for deciding when to issue a piece operates substantially as described above in relation to clues. In this alternative, a player attempts to collect all pieces of a set and when they do so they can redeem the set for a prize. In some embodiments, this will form a secondary 20 game, for example where the secondary game is to be the first person to redeem the set. In some embodiment, the player's establishment of an entitlement to all the pieces will be sufficient and accordingly, depending on the embodiment, the input 1020 to prize issuer 1010 may be a 25 piece and/or entitlement - i.e. the player will not have to provide the pieces in some embodiments. The method of the first embodiment is summarised in Figure 11. The method 1100 involves establishing that a player 30 is entitled to a clue in a primary game 1110, issuing a clue entitlement 1120, receiving the clue entitlement 1130 and issuing a clue 1140 which then can be employed in the secondary game 1150. 35 The method of the alternative embodiment is summarised in Figure 12. The method 1200 involves establishing that a player is entitled to a piece 1210, issuing a piece 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 18 entitlement 1220, receiving a piece entitlement 1230, issuing the piece 1240, determining whether all pieces have been received and if so awarding the prize and if not returning to step 1210. 5 Persons skilled in the art will appreciate that the above functions, such as the clue issue entitlement mechanism and the clue issuer can be embodied, for example, in part, by program code executed by processor 60. Persons skilled 10 in the art will appreciate that such program code can be supplied in a number of forms, for example, on a computer readable medium such as a disk or a memory or as a data signal which can be downloaded. 15 In an alternative embodiment, the clues or clue entitlement are issued in response to play in the primary game for subsequent use during later play of the primary game. 20 Example 1 Great American Treasure Hunt (GATH) This is a version of the game, where the clues are used to 25 solve a puzzle in a special secondary game. The special games are played at regular intervals - in this example one per week. 30 A special game features a treasure hunt, where the players with a predetermined number of clues are required to find the treasure using the information provided in the clues. Players acquire the clues by playing clearly identified 35 GATH machines in the week preceding the special game. The clues are downloaded each week to equipment attached to the GATH machines. 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 19 In the course of playing the GATH machines, tickets are issued to players which include a printed image or message of a clue and a date on which the ticket was issued. 5 A Master of Ceremonies will conduct the special game. Players prove their entitlement to play the special game by showing sufficient of their tickets to the master of ceremonies to prove their entitlement. When the master of 10 ceremonies announces the commencement of the game, the entitled players play the treasure hunt game and use their clues to try to find the treasure. After a period of time, the master of ceremonies declares 15 the treasure hunt completed and players are awarded prizes according to the treasure which they have found. There can be a number of variations, for example: 20 Small time event - players play machines, get clues, use the clues to solve a problem (eg a treasure hunt) win a prize. All this can happen in one night. This can happen at a different machine or at a Board and this can be run by a Master of Ceremonies. 25 Bigger event - players play machines, get clues, at a special time - eg once per week, they use their clues to solve a problem. A Master of Ceremonies can oversight this. The problem can be solved at a machine or 30 independent of a machine. Bigger event - same as above, but players who reach a certain standard in round one, once per week are invited to participate in a bigger event once per month. Once 35 again, a Master of Ceremonies can oversight. Biggest event - same as above, but played say once per 4844312 _1 (GHMatters) P62605.AU.4 6/11/13 - 20 year. Entry to the event comes from success in the prior rounds (so you are earning your way up the success ladder or we can market it as a platinum level player). All players gather at a location and use their clues to hunt 5 the grounds with their spades etc. to find the treasure.
