BACKGROUND OF THE INVENTION

The present invention relates to a gaming system, a controller, and method for awarding prizes.
Many venues employ controllers for awarding prizes to one or more of a plurality of gaming devices participating in a linked event. For example, in a linked event where jackpot prizes are awarded, a portion of turn-over on each gaming device will typically be forwarded to a jackpot controller as a contribution. That is, part of each wager goes towards the jackpot. The technique can be extended to a so called wide area jackpot where gaming devices from a number of different venues contribute to a single jackpot pool.
One common way of awarding a jackpot is a so called mystery jackpot where a trigger value, generally in a prize range, is randomly selected and stored by the jackpot controller. The jackpot controller determines to award the jackpot prize when the contributions cause the value of the jackpot pool to reach the trigger value.
While such techniques provide an opportunity for players to win large jackpot prizes, the need exists for alternative gaming systems in order to maintain or increase player enjoyment.

Further Detail of the Controller

The following embodiment is described in the context of a linked system 100A whereby a plurality of gaming devices contribute to individual prize pools from which the associated prizes are drawn. The gaming devices communicate with a prize server implementing a prize pool controller (which manages each of the individual prize pools), over a network such as the network 130 previously described with reference to FIG. 1. Prizes are awarded from the prize pool responsive to a gaming device detecting an internal randomly generated prize trigger, which is independent of a game outcome. It will be appreciated that in embodiments the individual gaming devices may contribute to a common jackpot prize pool and the individual prizes determined separately for each gaming device based on a prize determination criteria such as, for example, the amount which the particular gaming devices has contributed towards the prize pool.
To carry out aforementioned functionality, each of the gaming devices (hereafter gaming machines) employ a prize controller 131, as shown in FIG. 5 a. In the example embodiment, the prize controller 131 is incorporated into the game controller 301. For simplicity, only those modules needed to carry out embodiments of the invention are illustrated in FIG. 5 a.
The prize controller 131 includes a processor 520 which is arranged to carry out functions associated with generating the prize trigger and determining when the prize trigger has occurred. It will be apparent that the processor 520 implements a number of modules, namely a random number generator 521, trigger value determination module 522 and award module 524, based on program code stored in memory 540.
In the presently described embodiment, the trigger is associated with an accumulated turn-over value for the gaming device which is set based on both a randomly determined prize pool trigger value and the percentage contribution towards the prize pool. With the aid of the random number generator 521, the prize controller randomly selects the prize pool trigger value such that the trigger value falls within a range based on a required return to player (RTP) for the gaming device (i.e. as specified in memory 540), as will be described in more detail in subsequent paragraphs with reference to FIG. 6. It will be appreciated that by utilising the gaming machine prize controller 131 to make the random determinations (in contrast to conventional systems whereby all jackpot prize triggers are randomly determined by the jackpot controller), the jackpot controller can be classified as “associated gaming equipment” which is not subject to the same level of regulatory approval. This is advantageous since it means that the jackpot controller can be manufactured for a reduced cost and implemented in a faster time frame than conventional systems, due to the less stringent regulatory constraints.
The prize pool range and current prize pool value may be advertised to players of the gaming device. The accumulated turn-over trigger value is stored as trigger parameter data in memory 540. In this embodiment the value remains set until the associated prize has been awarded, at which time the determination module 522 randomly generates a new accumulated turn-over trigger value.
Upon completion of each game, the determination module 522 inspects the relevant machine parameter (in this example, accumulated turn over) to determine whether the accumulated turn-over trigger value has been reached. If a positive determination is made, the determination module 522 requests a payout value from a prize server 110, as will be described in more detail below, before awarding the associated prize.
As previously discussed, prizes are awarded from a prize pool. As individual games are played on the gaming machines 120, data indicative of the contributions made by each machine in those games is sent over the network 130 to a prize pool controller 134, implemented by the prize server 110. A schematic of the pool controller 134 is shown in FIG. 5 b. The pool controller 134 operates in much the same manner as a conventional jackpot controller in so far as maintaining the prize pool is concerned irrespective of whether individual prize pools are being maintained or whether a single pool for all participating gaming machines. That is, the pool controller 134 processes each machine contribution utilising a contribution processor 138 and updates prize pool data 140, stored in memory 142, by an amount corresponding to the contribution. Similarly, when prizes are awarded from the prize pool, the prize pool data 140 is adjusted to reflect the payout value. In other words, the prize pool data 140 reflects the total prize pool value at any given time.
In an embodiment the prize pool controller 134 additionally maintains rule data 144 (also stored in memory 142) which specifies how the prize pool is to be divided up, if at all, for each awarded prize. The rules may vary for different machines and also for different time periods. For example, the rules may be set up to award larger prizes during special time periods. In another embodiment, the value of the prize may depend on the number of machines contributing towards the pool (i.e. where a common prize pool is being maintained), the current wager amount of the machine which is to be awarded the prize, the total contributions made by that machine toward the prize pool, etc. Any number of different rules are envisaged, depending only on the desired implementation. Alternatively, in a simplified embodiment, the prize value may simply correspond to the value of the prize pool.
Upon receipt of a payout value request from a gaming machine 120, the prize pool controller 134 inspects the prize pool data 140 and rule data 144 to determine a payout value. For example, if the current prize pool value is $1,000 and the rule data specifies that 50% of the pool is to be awarded to that particular machine (e.g. which is determined based on the contributions made by the machine toward the prize pool), the payout value will be $500. Data representative of the payout value is then sent back to the gaming machine which issued the request, over the network 130. The award module 524 implemented by that gaming machine processes the data representative of the payout value and awards the player with a corresponding prize.
An example methodology 600 is summarised in FIG. 6. At step 602, a prize trigger value for a gaming device/machine is randomly determined by the controller 131. The prize trigger is independent of a game outcome of the gaming device. In this case, the prize trigger is based on “coin in” (i.e. the amount wagered on the gaming device) and the prize pool trigger value set to fall between the lower limit of $1000 and the upper limit of $2000. With the aid of the random number generator, a randomly generated prize pool trigger value is set at $1,567.28. Based on a gaming device contribution of 1.5%, the trigger value for the gaming device is $14485.33. Game play is then carried out as per steps 604 through 606 such that at the conclusion of each game the trigger value determination module 522 determines whether the coin in value has exceeded the trigger value (step 610).
Responsive to determining that the prize trigger has occurred, at step 612, a prize from a prize pool is awarded to the gaming device utilising the award module 526. Otherwise, play continues as normal (step 614).
Although in the above embodiments a monetary prize was awarded to the gaming machines, it will be understood that other forms of prizes may be awarded. For example, in an embodiment, upon determining that the trigger has occurred, the gaming machine may initiate play of a feature game. Various levels of prizes may be awarded in the feature game. For example, the feature game may have a major prize value corresponding, for example, to the total prize pool value. Secondary prizes of lesser value may be awarded for various other game outcomes. Persons skilled in the art will appreciate that value of the secondary prize can vary depending on the actual implementation. For example, in some implementations, the secondary prize value will vary as a function of time or as a function of the value of the prize pool.
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 without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute an admission that the publication forms a part of the common general knowledge in the art, in Australia or any other country.
In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due 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 invention.
