FIELD OF THE INVENTION

The present invention generally relates to a method of gaming, a game controller, a gaming device and a gaming system.

BACKGROUND OF THE INVENTION

With the increase of gambling at gaming venues has come increased competition between gaming venues to obtain a larger share of the total gambling spend. Gaming venue operators have therefore continuously looked for new variations and types of games in order to attract both new and return customers to their venues.
In response to this need, suppliers of gaming devices and systems have attempted to provide the sought after variety, while still developing games that comply with the relevant regulations in the jurisdiction of the gaming venue operator. Suppliers of gaming devices therefore are faced with restrictions on the types of games and gaming apparatus that are allowable, both in terms of the prevailing regulations and in terms of providing a return on investment to the gaming venue operators.
In addition, it is important that a player be able to understand the operation of a game quickly so that the player can start to quickly play the game and therefore extract maximum entertainment from the game.
Progressive jackpots may be offered on gaming machines. A progressive controller may be programmed to accumulate a percentage of the turnover bet on the machine, that percentage being accumulated in a progressive pool. On the occurrence of a predetermined event, the amount of money in the pool may be awarded to a player.
Recently progressive jackpot gaming systems have been implemented which operate across a group of linked gaming machines, accumulating a percentage of turnover bet on all of the linked machines into one or more progressive pools. Again the contents of a particular progressive pool may be awarded to a player when certain trigger conditions are met.
While the modified player progressive systems have increased player interest, there is still a need for further gaming systems.

One or more of the peripheral devices, for example the card/ticket reader 108 may be able to communicate directly with the network card 112.
The game controller 101 may also include a random number generator 113, which generates a series of random numbers that determine the outcome of a series of random game events played as part of a game on the gaming apparatus 100. As explained in more detail in relation to FIG. 4, the computational device 102 may include two or more controllers or processors, which may be local or remote from each other and the displays 106. It will be appreciated that the random number generator may generate pseudo-random or true-random numbers depending on how it is configured.
FIG. 3 shows an exemplary block diagram of the main components of the memory 103. The RAM 103A typically temporarily holds program files for execution by the computational controller 102 and related data. The EPROM 103B may hold 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 computational controller 102 using protected code from the EPROM 103B or elsewhere.
While the foregoing description has been provided by way of example of the embodiments of the present invention as presently contemplated, which utilize gaming apparatus and machines, those skilled in the relevant arts will appreciate that the present invention also may have application to internet gaming and/or have application to gaming over a telecommunications network, where handsets are used to display game outcomes and receive player inputs. Herein any device operable by a player to play a game such as the above described apparatus and machine is generically referred to as a gaming device.
FIG. 4 shows a gaming system 200. The gaming system 200 includes a network 201, which for example may be an Ethernet network. Gaming devices 202, shown arranged in three banks 203 of two gaming devices 202 in FIG. 4, are connected to the network 201. The gaming devices 202 may be gaming machines 10, as shown in FIG. 1 or form part or all of another gaming apparatus 100.

For example, a game server 205 may generate game outcomes for games played on the gaming devices 202, a database management server 206 may manage the storage of game programs and associated data for downloading or access by the gaming devices 202 in a database 206A, and a jackpot server 207 may control one or more jackpots associated with the gaming devices 202.
Further servers may be 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 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.
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 through a firewall 211.
An embodiment, which includes the feature of incrementing the progressive prize by a fixed amount upon the progressive prize not being awarded is illustrated in FIGS. 5A, 5B and FIG. 6. The embodiment describes an arrangement, where the method of gaming involves conducting a base game. The player can wager on the base game in a conventional manner. The base game may be, for example, a spinning reel game. In the alternative, the player may also place an additional ante bet when initiating a play of the base game. The ante bet provides eligibility for a first level feature game, exemplified below as the “Miss Kitty” feature from which the player can access three second level features as described in further detail below. The three second level features can each result in the award of a different progressive prize. The prize pools for the respective progressive jackpots are only incremented when the ante bet is made. The progressive prize pools are incremented in a number of ways as described below but notably, including increments of the respective prize pool by a fixed amount when a second level feature game is lost. In addition to the progressive jackpot prize, a mystery jackpot is provided which can be won irrespective of whether an ante bet is made.
Referring to FIG. 5A, the method of the embodiment involves receiving 1601 a player wager. It is determined 1602 whether the wager includes an ante-bet. If the player does not place the ante-bet, the player is not eligible for the Miss Kitty and second level features games but is still eligible 1603 for the mystery jackpot and accordingly the mystery jackpot pool is increased based on a percentage of the amount bet by the player. As in conventional mystery jackpots, the prize pool can include a seed pool such that when a mystery jackpot is awarded the mystery jackpot can start from a non zero number.
If the bet includes the ante-bet then the player is eligible 1604 for the mystery jackpot, the feature game, and the second level feature games including the progressive jackpots. Accordingly increments apply to both the mystery and progressive jackpots 1605 and there will be increments provided during the base game to both the mystery and progressive jackpot pool. It is determined at the end of each play of the base game whether a trigger condition has been met in respect of this play of the base game. If no trigger occurs, the process proceeds to the start and awaits the receipt 1601 of a player wager.
If a trigger condition occurs then the first level, Miss Kitty, feature game is started 1607. Referring now to FIG. 5B, in this example of a second level feature game, the player and “Miss Kitty” who is an animated fanciful cat each roll a pair of dice. If the player's total equals or exceeds Miss Kitty's total 1620 the player is awarded 1621 bonus credits or some other award which is typically based on the player's score. For example a multiplier of the number of spots shown on the player's dice.
If either the player or Miss Kitty role a double, the player is awarded bonus credits and may select to play any of three feature games as will be described in further detail below. Persons skilled in the art will appreciate that the number of feature games can vary and is advantageously a plurality of games with the upper limit of games corresponding to a desired number of progressives to be provided by the game. The third alternative 1680 is Miss Kitty's score is greater than the player's score. If this is the case a consolation prize, for example between 150 and 500 credits is awarded, and the progressive jackpot levels are incremented by set amounts of credits. That is each of the three progressive levels is incremented separately by fixed amounts. The amount that each jackpot is incremented may be the same or different. The increment is typically determined and applied at a progressive controller in data communication with a gaming device on which the game is played. However, persons skilled in the art will appreciate that progressives could only obtain contributions from one gaming machine be monitored at the gaming device. Further, there are two possible modes of operation, one where the gaming device simply indicates to a controller that there is a need to make an increment and the progressive controller applies the increment and another where the gaming device determines the progressive amount and communicates it to the progressive controller.
Returning now to FIG. 5B, the player is offered a choice 1631 of three selectable features each of which is associated with a respective one of three progressive jackpots. Typically, the size of the jackpots are different and are commensurate with the probability of winning a jackpot by play of the selected feature such that the player has a higher probability of obtaining award of a jackpot if they choose a lower value progressive jackpot, for example in the range of $100.00 to $200.00 than they have if they choose a game having an associated higher value jackpot, for example in the range of $2,000 to $4,000. Once the player selects the feature, the selected feature is played 1632 and it is then determined whether the player wins 1633. If the player loses then the game involves incrementing the relevant progressive associated with the selected feature by a fixed amount 1635. In the alternative if the player wins then they are awarded the progressive jackpot associated with the selected feature. The progressive jackpot pools may incorporate hidden seed pools in a manner known in the art to enable them to start from non-zero amounts.
In one example, the three features may be as follows: 1) a “granny” feature where the player has five shots determined by random trials to hit bottles displayed on a fence post. A person skilled in the art will appreciate that the reference to “random” above includes pseudo random. Accordingly, the gaming device determines by random number generator 113 how many bottles the player hits. The gaming device also determines whether an animated character named “granny” hits the bottles, and if the player's score equals or exceeds granny's score, the granny level progressive jackpot is awarded. Alternatively, if granny's score exceeds the player's score, the granny level progressive jackpot value is incremented by a set amount. Persons skilled in the art will appreciate that the odds of the player and granny hitting bottles could be 50/50 for each bottle or weighted in some fashion such that the player and granny need not necessarily have the same odds of hitting a bottle.
The second feature is a “bandito” feature where twelve windows are presented on the screen and the banditos hidden behind one of the twelve windows. The player gets four hits to try and find the bandito. If the player finds the bandito, the player wins the bandito jackpot level value. If the player does not find the bandito, the bandito jackpot level is incremented by a set amount.
The third feature is the “gambler” feature. The gambler is dealt two aces. The player is dealt five cards. If the player's poker hand beats two aces, the gambler progressive jackpot level is awarded. If the player's hand does not beat the pair of aces, the gambler jackpot level is incremented by a set amount.
FIG. 6 is a functional block diagram of a gaming system 1700 of a exemplary embodiment for implementing the method of FIG. 5. FIG. 6 shows a gaming system 1700 having a gaming device 700 and a jackpot controller 70. Persons skilled in the art will appreciate that in practice a plurality of gaming devices will be connected to the same jackpot controller in order to provide for substantial value jackpot pools as is shown in FIG. 4 where a plurality of gaming. However, a single gaming device 700 is shown in FIG. 6 for ease of exposition. It will be appreciated that herein it is assumed that each gaming device is eligible for at least one jackpot prize (provided it is being played). In other embodiments, eligibility criteria may be applied. For example, that the gaming device is in a particular part of a venue, offers a designated game, the wager is of a certain level, or the player has inserted a player tracking card.
Persons skilled in the art will appreciate that the connection between the gaming device and the jackpot controller 70 can be a conventional network connection such as an Ethernet. Persons skilled in the art will also appreciate that the game device 700 can be exemplified in the form of a gaming machine 10, 100 as described in relation to FIGS. 1 and 2 but as indicated elsewhere in the specification, the player interface which the player plays and the game controller need not necessarily be co-located.
Turning now to FIG. 6 the gaming device 700 has a player interface 50 in data communication with a game controller 60. The player interface includes a credit input mechanism 52, a display 54 and a game play mechanism 56. The game play mechanism includes a number of buttons and/or a touch screen to enable the player to interact with the game controller 60. For ease of exposition, a subset of these is shown including an ante-bet button 56X and feature selection buttons 56A, 56B and 56C.
In the embodiment, a series of modules are implemented by a processor 62 executing program code stored in memory 64 such that the game controller is configured to carry out the functions described below. Persons skilled in the art will appreciate that these modules could be provided in different ways, including by providing dedicated circuits configured to carry out the functions described below. Further, persons skilled in the art will appreciate that there will be other modules, for example a random number generator and a display controller for controlling the display and that these are omitted for the sake of clarity. The game controller 60 includes a base game module 621 which is arranged to carry out a base game each time the player operates input mechanism to place a wager. The game controller 60 also includes an eligibility module 625 which determines whether than ante-bet has been placed with ante-bet button 56X. When an ante-bet is placed the eligibility module activates progressive contribution module 626 which sends for each play 625 a of the game data to the jackpot controller to indicate that its progressive controller 705 should increment the progressive value 721 to 723 which are stored in progressive value database 720. To this end the progressive controller 705 includes a contribution handler 710 which knows the proportional amounts which each of the progressives 721, 722, 723 should be incremented each time there is a play of the game. In addition the eligibility module actives the trigger monitor 623A of the outcome evaluator 623 which is arranged to evaluate the outcomes based on base game data 641.
It will be appreciated there is also a mystery module 628 which operates irrespective of whether the ante-bet has been placed in order to send contributions based on a percentage of turnover to the mystery controller of the jackpot controller. The mystery controller 740 increments the mystery pool 741 accordingly.
The base game data 641 also allows the outcome generator 624A to generate the outcomes which as described above may be, for example, those of a spinning reel game. When the trigger monitor 623A determines that a trigger condition is met, for example, the occurrence of three designated scattered symbols at display positions of the virtual reels of a video spinning reel game, the trigger monitor 623A activates the second level feature module 624. The feature module 624 includes a feature game outcome generator 624A which, in the example given implements the dice game of the Miss Kitty game which generates outcomes based on the feature game data 642 which in turn are evaluated by the feature evaluator 624B based on feature game data 624 which specifies the rules of the Miss Kitty game as described above. The feature module 624 also includes a feature selection module to enable a player to select the feature by operating buttons 56A, 56B, 56C to select one the features described above when the player wins eligibility to the feature. As described above, the feature module 624 is arranged such as to communicate when a loss of the feature game occurs or that the first level features to the contribution handler 710 of the progressive controller 705 so that it can increment the progressive 721, 722, 723 in the manner described above.
When the player wins the first level feature, the feature selection module 624C enables the player to select one of feature A, feature B, or feature C 627A, 627B, 627C; these features being associated respectively with a first progressive 721, a second progressive 722 and a third progressive 723. Persons skilled in the art will appreciate that while these features are all shown as being implemented by a second level feature module 627 they could equally be provided as separate modules which are instantiated as required based on the second level data 643 which specifies each of features A, B and C 643A, 643B, 643C and the rules associated with those games. As described above if the player loses any of these features, the progressive that is specifically associated with it is incremented. That is, for example, if feature A 627A is lost by the player then the player's losing amount which is fixed is added the progressive. Thus, giving the impression that the player has lost to the animated character that forms part of the feature as described above. At the end of play or at appropriate points during play the meter data 644 is updated to reflect the outcomes of play the amount wager, any amounts won, etc. This is viewable by player on display 54. Persons skilled in the art will appreciate that if the player wins one of the second level features then the award handler 730 awards the progressive to the player. The award handler 730 can function in the same way as typical progressive machines such as to arbitrate when two gaming machines claim a progressive in close proximity which of those is to be awarded the first progressive and which is to be awarded the second progressive.
Persons skilled in the art will appreciate that other arrangements are possible. For example, rather than the second level feature module 627 being implemented within the game controller is could be implemented elsewhere, for example within the jackpot controller. Further, while the mystery and progressive jackpot controllers 740, 705 are shown within a single jackpot controller 70 and this is advantageous in terms of reducing equipment, it is not strictly necessary and they can be provided as separate controllers.
