The foregoing summary, as well as the following detailed description of certain embodiments of the present invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, certain embodiments are shown in the drawings. It should be understood, however, that the present invention is not limited to the arrangements and instrumentality shown in the attached drawings.
DESCRIPTION OF CERTAIN EMBODIMENTS OF THE INVENTION
Although the following discloses example methods, systems, articles of manufacture, and apparatus including, among other components, software executed on hardware, it should be noted that such methods and apparatus are merely illustrative and should not be considered as limiting. For example, it is contemplated that any or all of these hardware and software components could be embodied exclusively in hardware, exclusively in software, exclusively in firmware, or in any combination of hardware, software, and/or firmware. Accordingly, while the following describes example methods, systems, articles of manufacture, and apparatus, the examples provided are not the only way to implement such methods, systems, articles of manufacture, and apparatus.
When any of the appended claims are read to cover a purely software and/or firmware implementation, at least one of the elements in an at least one example is hereby expressly defined to include a tangible medium such as a memory, DVD, CD, etc. storing the software and/or firmware.
Referring to the drawings, there is shown a schematic block diagram of a gaming system 10 arranged to implement a probabilistic base game of the type wherein several symbols from a set of symbols are randomly displayed, and a game outcome is determined on the basis of the displayed symbols. With some such probabilistic games, the set of symbols include standard symbols and function symbols, and the outcome of the base game is determined on the basis of the displayed standard symbols and the function associated with any displayed function symbol. For example, standard symbols may resemble fruit such as apples, pears and bananas with a win outcome being determined when a predetermined number of the same fruit appear on a display in the same line, scattered, and so on. The function associated with a function symbol may be for example a wild function wherein display of the function symbol is treated during consideration of the game outcome as any of the standard symbols. A function symbol may be represented as the word “WILD”, a star, or by any other suitable word or symbol. Other functions are also envisaged such as scatter functions, multiplier functions, repeat win functions, jackpot functions and feature commencement functions.
The gaming system is arranged to facilitate storage of game state information associated with a game played by a player at a gaming machine and to facilitate retrieval of the game state information associated with the player should the player subsequently return to the gaming machine so that the player may continue with the game.
In this way, the gaming machine on which the game state information is stored becomes linked to the particular game associated with the game state information and the player associated with the game such that the player has an incentive to return to the particular gaming machine in order to continue with the game. In this way, the player develops an affinity for the particular gaming machine which increases player enjoyment.
The game state information may relate to a base game and/or a feature game and may be of a type including a plurality of stages or levels with a player receiving a reward based on the stage or level achieved. For example, the game state information may be associated with a feature game wherein a mission scenario is presented to the player. The outcome of the mission scenario, or the level of the mission scenario achieved, may be skill based, part skill based, or random.
The game state information stored at the gaming machine may include game state information associated with multiple players, and the gaming system may be arranged to reward players based only on their associated game state information or based on a comparison of the game state information. For example, a reward may be provided to the player achieving the highest level of the feature game.
In one embodiment of the present gaming system, operation is such that a feature game is triggered when a defined trigger condition exists during implementation of a base game, which may be occurrence of a defined game outcome, occurrence of a game event during a game such as display of a particular symbol, in response to player input, based on the amount or type of bet placed, when a special game is purchased by a player, or based on any other condition. The feature game in this embodiment is a multi level mission scenario type game and the gaming system is arranged to store game state information indicative of the current game state including the level achieved by a player.
Referring to FIG. 1, a schematic diagram of core components of a gaming system 10 is shown. The core components include a player interface 30 and a game controller 32. The player interface 30 is arranged to enable interaction between a player and the gaming system and for this purpose includes input/output components for the player to enter instructions and play the game.
Components of the player interface 30 may vary but will typically include a credit mechanism 34 to enable a player to input credits and receive payouts, one or more displays 36, at least one of which includes a touch screen, and a game play mechanism 38 arranged to enable a player to input game play instructions.
The game controller 32 is in data communication with the player interface 30 and typically includes a processor 40 arranged to process game play instructions and output game player outcomes to the display 36. Typically, the game play instructions are stored as program code in a memory 42 that can also be hardwired. It will be understood that in this specification the term “processor” is used to refer generically to any device that can process game play instructions and may include a microprocessor, microcontroller, programmable logic device or other computational device such as a personal computer or a server.
A functional diagram illustrating operative components of the game controller 32 is shown in FIG. 2.
In this example, the memory 42 is arranged to store symbols data 14 for use in a game. The memory 42 is also arranged to store game instruction data 18 indicative of game instructions usable by the gaming machine 10 to control operation of the game.
The game controller 32 includes a game implementer 20 which is arranged to implement a base game, in this example of a type wherein several symbols are selected from the available symbols 14, for example by spinning reels containing the symbols and stopping the reels so as to display at least one symbol on each reel. In this example, the selection carried out by the game implementer 20 is made using a random number generator 22.
It will be appreciated that the random number generator 22 may be of a type which is arranged to generate pseudo random numbers based on a seed number, and that in this specification the term “random” will be understood accordingly to mean truly random or pseudo random.
With this embodiment, the game implementer 20 is also arranged to implement a feature game when a trigger condition is determined to exist. A trigger condition may be occurrence of a game event such as a defined game outcome, or may be detection of a defined input from a player.
In this example, the feature game takes the form of a multi-level scenario type game, although it will be understood that any type of feature game is envisaged.
The game controller also has an associated data storage device 24, in this example in the form of a hard drive, for storing game state data 26 associated with a plurality of players. In this example, game state data for each feature game implemented by the gaming system is stored on the hard drive 24 for subsequent retrieval so that the associated player may continue with the game.
The game controller 32 also includes an outcome evaluator 28 which in accordance with the game instructions 18 determines game outcomes during a base game or feature game.
In this example, during a base game the game outcome is based on displayed symbols and defined winning symbol combinations, and during a feature game the game outcome is based on the level of the multi-level game achieved or based on a comparison between game state information associated with the player and game state information associated with other players. However, other alternatives are possible. For example, during a feature game, the game outcome may be based on the level of the game achieved with a bonus awarded based on a comparison between game state information associated with the player and game state information associated with other players.
In the embodiments described below, the game implementer 20 and the outcome evaluator 28 are at least partly implemented using the processor 40 and associated software, although it will be understood that other implementations are envisaged.
The gaming system 10 can take a number of different forms.
In a first form, a stand alone gaming machine is provided wherein all or most components to implement the game are present in a player operable gaming machine.
In a second form, a distributed architecture is provided wherein some of the components to implement the game are present in a player operable gaming machine and some of the components to implement 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, 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 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 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, and so on. Other variations will be apparent to persons skilled in the art.
A gaming system in the form of a stand alone gaming machine 50 is illustrated in FIG. 3. The gaming machine 50 includes a console 52 having a primary display 54 on which is displayed representations of a game 56 that can be played by a player. A mid-trim 60 of the gaming machine 50 houses a bank of buttons 62 for enabling a player to interact with the gaming machine, in particular during game play. The mid-trim 60 also houses a credit input mechanism 64 which in this example includes a coin input chute 64A and a bill collector 64B. Other credit input mechanisms may also be employed, for example, a card reader for reading a smart card, debit card or credit card.
A top box 66 in this example includes a secondary display 68 on which a feature game is implemented, although it will be understood that, as an alternative, the feature game may be implemented on the primary display 54. Artwork and/or information may be provided on a front panel 69 of the console 52. A coin tray 70 is mounted beneath the front panel 69 for dispensing cash payouts from the gaming machine 50.
The or each display 54, 68 may be in the form of a video display unit, particularly a cathode ray tube screen device. Alternatively, the or each display 54, 68 may be a liquid crystal display, plasma screen, or any other suitable video display unit. In the present embodiment wherein the secondary display is used to implement a feature game, the secondary display 68 includes a touch screen usable by a player to control movement of an object during feature game play. In an alternative embodiment wherein the primary display is used to implement a feature game, the primary display 54 includes a touch screen.
The primary display 54 in this example is arranged to display representations of several reels, each reel of which has several associated symbols. Typically 3, 4 or 5 reels are provided. During operation of a base game, the reels first appear to rotate then stop with typically three symbols visible on each reel. Base game outcomes are determined on the basis of the visible symbols together with any special functions associated with the symbols.
A player tracking module (PTM) 72 having a display 74 is also provided. The PTM 72 allows the player to interact with a player loyalty system. The PTM has a magnetic card reader for the purpose of reading a player tracking device, for example as part of a loyalty program. However other reading devices may be employed and 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. In this example, the PTM 72 is a Sentinel III device produced by Aristocrat Technologies Pty Ltd.
The PTM 72 also functions to identify a player for the purpose of identifying game state information associated with the player in the data storage device 24 so that desired game state information can be retrieved by the gaming machine and the game associated with the game state information continued, or for the purpose of storing new game state information and associating the game state information with the correct player.
While the present embodiment uses a PTM 72 to identify a player, it will be understood that alternatives are possible. For example, the gaming system 10 may be arranged so as to facilitate identification of a player by receiving identification information from a player such as login and password information, for example using a touch screen, using biometric sensors, RFID readers, or in any other way.
After a player has been identified, the gaming system may be arranged so that it is assumed that the identity of the player remains the same until an indication is received to indicate that the player may no longer be present or may have changed. For example, if no input or coin-in is received from a player for a defined period of time, the gaming system may be arranged to assume that the player is no longer present. Alternatively, the gaming system may include a video camera and the gaming system arranged to recognise when a person is present in front of the gaming machine and to assume that the player is no longer present when a person is not detected in front of the machine for a defined period of time.
In order to facilitate identification of a gaming machine by a prospective player, each gaming machine may be provided with a unique identifier, defined colour schemes, defined lighting schemes, a scrolling leaderboard, or any other identification arrangement. The gaming system may also be arranged to provide each player with a ticket which identifies the stored game(s) and gaming machines on which the games are stored.
FIG. 4 shows a block diagram of operative components of a gaming machine 100 which may be the same as or different to the gaming machine shown in FIG. 3.
The gaming machine 100 includes a game controller 101 having a processor 102. Instructions and data to control operation of the processor 102 in accordance with the present invention are stored in a 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.
FIG. 5 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 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 elsewhere.
The game controller 101 also includes a data storage device, in this example in the form of a hard drive 114, arranged to communicate with the processor 102 and to store and retrieve game state data. While the hard drive 114 in FIG. 4 is shown separate to the memory 103, it will be appreciated that the hard drive may constitute the mass storage device 103C shown in FIG. 5, with a portion of the mass storage device dedicated to storing game state data.
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 a player interface 120 of the gaming machine 100, the player interface 120 having several peripheral devices. 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 devices. A random number generator module 113 generates random numbers for use by the processor 102.
In the example shown in FIG. 4, the peripheral devices that communicate with the game controller 101 include one or more displays 106, a touch screen and bank of 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 based on the specific implementation.
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 data or commands from the central controller, server or database.
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 may be provided remotely from the game controller 101.
FIG. 6 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, a LAN or a WAN. In this example, two banks 203 of two gaming machines 202 are connected to the network 201. The gaming machines 202 provide a player operable interface and may be the same as the gaming machines 40,100 shown in FIGS. 3 and 4, or may have simplified functionality depending on the rules, guidelines, requirements, and/or preferences to implement game play. While banks 203 of two gaming machines are illustrated in FIG. 6, banks 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. 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.
In a thick client embodiment, a 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 205 and the gaming machine 202 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 gaming system enables players to participate in a Jackpot game, a Jackpot server 207 will be provided to monitor and carry out the Jackpot game.
In a variation of the above thick client embodiment, the gaming machine 202 may implement the game, with the game server 205 functioning merely to serve data indicative of a game to the gaming machine 202 for implementation.
With this implementation, a data signal containing a computer program usable by the client terminal to implement the gaming system may be transferred from the game server to the client terminal, for example in response to a request by the client terminal.
In a thin client embodiment, the 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 gaming machine will receive player instructions, and pass the instructions 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 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 system 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 monitor the network 201 and the devices connected to the network.
The gaming system 200 may communicate with other gaming systems, other local networks such as a corporate network, and/or a wide area network such as the Internet, for example through a firewall 211.
The gaming system 200 also includes a loyalty program server 212 and a feature database 214.
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 plurality of different computers. For example, elements may be run as a single “engine” on one server or a separate server may be provided. For example, the game server 205 could run a random number generator engine. Alternatively, a separate random number generator server could be provided.
A specific example will now be described in relation to flow diagram 250 shown in FIG. 7 which illustrates steps 252 to 270 of a method of gaming implemented by a gaming system. In this example, the gaming machine is a stand alone gaming machine 50.
FIG. 7 depicts an example flow diagram representative of processes that may be implemented using, for example, computer readable instructions that may be used to facilitate game play. The example processes of FIG. 7 may be performed using a processor, a controller and/or any other suitable processing device. For example, the example processes of FIG. 7 may be implemented using coded instructions (e.g., computer readable instructions) stored on a tangible computer readable medium such as a flash memory, a read-only memory (ROM), and/or a random-access memory (RAM).
As used herein, the term tangible computer readable medium is expressly defined to include any type of computer readable storage and to exclude propagating signals. Additionally or alternatively, the example processes of FIG. 7 may be implemented using coded instructions (e.g., computer readable instructions) stored on a non-transitory computer readable medium such as a flash memory, a read-only memory (ROM), a random-access memory (RAM), a cache, or any other storage media in which information is stored for any duration (e.g., for extended time periods, permanently, brief instances, for temporarily buffering, and/or for caching of the information). As used herein, the term non-transitory computer readable medium is expressly defined to include any type of computer readable medium and to exclude propagating signals.
Alternatively, some or all of the example processes of FIG. 7 may be implemented using any combination(s) of application specific integrated circuit(s) (ASIC(s)), programmable logic device(s) (PLD(s)), field programmable logic device(s) (FPLD(s)), discrete logic, hardware, firmware, etc. Also, some or all of the example processes of FIG. 7 may be implemented manually or as any combination(s) of any of the foregoing techniques, for example, any combination of firmware, software, discrete logic and/or hardware. Further, although the example processes of FIG. 7 are described with reference to the flow diagram of FIG. 7, other methods of implementing the processes of FIG. 7 may be employed. For example, the order of execution of the blocks may be changed, and/or some of the blocks described may be changed, eliminated, sub-divided, or combined. Additionally, any or all of the example processes of FIG. 7 may be performed sequentially and/or in parallel by, for example, separate processing threads, processors, devices, discrete logic, circuits, etc.
During a base game, a plurality of reels are provided, with each reel including standard symbols and optionally one or more function symbols. Win outcomes are determined on the basis of the symbols visible at the display positions when the reels stop rotating.
In this example, five virtual reels are provided and, as such, representations of the reels are displayed on a graphical display device 54 of a gaming machine 50.
The gaming system is arranged to implement one or more feature games. A feature game may commence automatically on the basis of occurrence of a trigger condition, such as a game event occurring during a base game, or in response to player input.
As indicated at step 254, prior to commencing play of a game at a gaming machine, a prospective player is first identified, for example by the player inserting a player tracking card into the PTM 72 of the gaming machine or by entering login and password information into the gaming machine, for example using a touch screen. After identification is received at a gaming machine, a check is made to determine whether the player is registered with the system by comparing player information received from a player tracking card or embodied in the login information with stored player identification information. Player identification information may be stored locally at each gaming machine or may be stored remotely from the gaming machine, for example at a loyalty program server 212.
If the player is not already associated with the system, a registration procedure may be invoked wherein a player tracking card is issued to the player and/or login and password information communicated to the player and stored in the loyalty program server. A new player game state record is created in the local gaming machine hard drive 24 as indicated at steps 256 and 258. Each game state record is capable of holding game state data associated with one or more games played by the player associated with the game state record.
If the player is already associated with the gaming system, the player decides at step 260 whether to play a new game or continue with an existing game. If the player decides to continue with an existing game, the game state record associated with the player is retrieved from the local hard drive using player identification data retrieved from a player tracking card or entered by the player as login/password information, and the game state data relevant to the game desired to be continued by the player extracted from the game state record, as indicated at step 263.
The gaming system then implements the desired game, whether a new game or a continuation of an existing game, and prizes are paid if applicable.
In the present example, as indicated at steps 264 and 266, if a trigger condition is determined to exist, for example at least 3 scattered special symbols, a feature game is implemented which may be complementary to or different to the base game.
As indicated at step 268, the player may choose to finish the game, and as a consequence of finishing the game, game state information indicative of the current status of the game is stored in the local hard drive, as indicated at step 270.
The game state information may include game state information associated with one or more base games played by the player and/or one or more feature games played by the player. For example, in an embodiment wherein a multi-level mission scenario type feature game is implemented, the game state information may be indicative of only the level achieved in the feature game. Alternatively, the game state information may be indicative of one or more, or all, game related events occurring during both base games and feature games, including wins achieved, coin in, and so on.
During a feature game, the prizes paid may be based on the game state information associated only with the current game, such as the current level achieved, and/or based on a comparison between the current game state information and stored game state information associated with other players. In the latter example, it will be understood that a community or tournament experience is provided to a player even though the tournament is not occurring real-time.
It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments and/or aspects without departing from the spirit or scope of the invention as broadly described. For example, it will be apparent that certain features of the invention can be combined to form further embodiments. The present embodiments and aspects are, therefore, to be considered in all respects as illustrative and not restrictive.
