  • the present invention is particularly relevant to jackpot gaming systems in which a number of electric gaming machines (EGM' s) are networked.
  • EGM' s electric gaming machines
  • These gaming systems can be externally triggered promotional jackpots, EGM triggered jackpots and externally triggered regulatory jackpots .
  • EGM triggered jackpots require EGM' s specifically made or this purpose . Accordingly a club wishing to offer this facility with their EGMs must purchase new ones that offer this feature . All EGMs participating in a linked jackpot of this type typically must be of the same type , e.g. manufacturer and game . Furthermore they tend to have a relatively limited configurability in terms of prize values, return to player, number of levels and themes .
  • Australian patent application AU1999434453 discloses a prize awarding system which addresses the problems experienced by the above non-deterministic jackpot systems.
  • a random process is implemented with the desired statistical properties based on the actual occurrence of turnover . While such methods attempt to reduce computational load and critical timing requirements compared to jackpots that are triggered off specific plays of an EGM, there is still significant software complexity, computational load and real time requirements associated with these methods .
  • the actual statistical properties of the jackpot depend critically on details of the implementation and the system on which it runs. Verification of correct jackpot operation under all patterns of play and system load is time consuming and itself requires statistical analysis to interpret the results .
  • Another Australian patent number 589158 describes a system which consists of a number of poker machines producing an incrementing signal which is totalled by a counting means.
  • a jackpot is triggered when the counting means reaches a predetermined value, with the jackpot being awarded to the machine that caused the increment to go over the trigger value.
  • the system described in this patent application has a number of drawbacks .
  • the jackpot prize cannot be a fixed value. It is always dependent upon the amount of turnover before the trigger value is reached by the counting means .
  • the jackpot is triggered from a combined count from each of the EGMs . In the above system the jackpot is triggered based on a uniform distribution for the random number which is used as the trigger value .
  • the random number range used must have a lower bound of the jackpot minimum display/prize value and an upper bound of the maximum desired display/prize value, leading to the situation that as the display value approaches, the maximum probability of the win inherently increases .

  • FIG. 1 shows a gaming system 10 having three EGMs 11, 12, 13 which are linked to a gaming system controller 14.
  • This gaming system controller 14 consists of a site controller device 15, a jackpot trigger device 16 and a jackpot prize calculator 17.
  • An overhead display 18 is also provided above each of the EGMs 11, 12, 13.
  • the site controller 15 receives meter information from each of the EGMs over a communications network such as that utilising fibre optics, ethernet or RS485.
  • the meter information includes a meter representing the cumulative turnover of the gaming machine since it was commissioned.
  • the site controller monitors and stores the latest value of the EGM meters and in particular the turnover meter .
  • the site controller sends the latest turnover meter value for each EGM to the jackpot trigger device 16.
  • An accumulator located in the jackpot trigger device stores a turnover meter value for each EGM.
  • jackpot trigger device calculates a total accumulated value representing total meter turnover value for all of the EGM' s 11, 12, 13.
  • the site controller passes on this incremental change to the jackpot trigger device which in turn recalculates the total accumulated value.
  • total meter values are stored for each EGM, being a meter value to date.
  • the jackpot trigger device records the total turnover value of the gaming system at any particular instant as well as the total turnover value for each machine at any instant.
  • the jackpot trigger device also stores a jackpot trigger value which it calculates .
  • a comparator in the jackpot trigger device compares the current total accumulated value with the trigger value and if the total has reached or exceeded the trigger value the jackpot trigger device outputs a jackpot win signal to the EGM from the which the last incremented count value was received by the site controller and which resulted in the total accumulated value equaling or exceeding the trigger value.
  • jackpot win would be awarded by the jackpot trigger device when the total accumulated value was equal to the trigger value .
  • the total accumulated value would have to exceed the trigger value in order for the jackpot trigger device to award a jackpot win.
  • jackpot trigger device outputs a jackpot win signal this is transmitted to the winning EGM as well as to the overhead display device 18. This results in an appropriate display on both the winning EGM and the overhead display for the purposes of indicating the jackpot win .
  • the jackpot trigger value is calculated in a random selection process .
  • the jackpot prize calculator obtains a random value from a random number generator based on an appropriate probability distribution. For the purposes of this embodiment a uniform distribution is used. The result is then modified by an inverse distribution function to give the desired geometric distribution.
  • the random number generator follows a geometric distribution model.
  • the random generator has a discreet ransom variable X to follow a geometric distribution with a probability parameter P between 0 and 1 , the trials must meet the following requirements : a. The total number of trials is potentially infinite; b. There are just two outcomes of each trial success and failure; c . The outcomes of all the trials are statistically independent; and d. All the trials have the same probability of success .
  • the geometric distribution has the desirable property that the resulting probability of a win per unit of turnover is constant.
  • probability terms each unit of turnover is considered a trial and hence P is set to the desired probability of win per unit of turnover.
  • the result from the random number generator is added to a turnover offset value to give the jackpot trigger value .
  • the system may incorporate software and/or hardware which controls operation of each of the EGM' s and issuing of a jackpot prize.
  • the total turnover for the system is set to zero in step 26.
  • the site controller polls each EGM to receive the latest turnover value of each EGM' s turnover meter. The value for each EGM turnover meter is then added to a total turnover meter located in the jackpot trigger device.
  • the jackpot trigger device in step 29 calculates a random value which is based on the value from a random source transferred to have a geometric distribution.
  • the trigger value is then calculated in step 30 by adding the random value to the total turnover value as received from the total turnover meter .
  • step 31 updating of this meter is completed.
  • step 32 if there is a change in the meter value of any EGM this is passed onto the site controller which in step 33 sets a new turnover value for the total turnover meter.
  • step 34 if polling results in the previous turnover for an EGM equaling the new turnover, then the total turnover meter updating is complete. If however the previous turnover does not equal the new turnover then the new value for the total turnover meter is set to a total turnover value currently stored minus the previous turnover for the EGM plus the new turnover in step 35. This means that if there has been an incremental increase in the turnover meter this is added to the total turnover value .
