Abstract: A jackpot triggering method comprising: determining a jackpot trigger value from a current value of at least one jackpot trigger parameter; generating a submission value in response to receipt of a contribution associated with a gaming device participating in the jackpot, by using a value of at least one contribution parameter associated with the contribution as a seed value to randomly generate the submission value; and making a jackpot award if the submission value corresponds to the jackpot trigger value.

Abstract: An electronic gaming machine, an electronic gaming machine method, and an electronic monitoring device for interfacing with a gaming machine are provided to permit game play for a time period and to allow subsequent periods of game play for the time period following the expiration of each preceding time period of game play. The arrangement permits monitoring data concerning the amount of game credits, winnings and losses on the gaming machine during each time period of game play. On the occurrence of aggregated losses reaching a set threshold amount there is inhibition of further game play for the remainder of the time period of game play. A computer programme code for enabling the above to be achieved is disclosed. A tangible computer readable medium comprising the programme code is also disclosed. A data signal comprising that programme code is also disclosed.

Abstract: A jackpot system comprising a first jackpot controller to act as a master jackpot controller and a second jackpot controller to act as either a master or a slave jackpot controller. The first jackpot controller acts as the master jackpot controller by conducting a jackpot during which the master jackpot controller aggregates jackpot data and periodically communicates the aggregated data to the second jackpot controller. The second jackpot controller acts initially as the slave jackpot controller and communicates jackpot data to the first jackpot controller for aggregation. The second jackpot controller stores the aggregated data received from the first jackpot controller and acts as the master controller if the master jackpot controller fails by continuing to conduct the jackpot based on the stored aggregated data and by aggregating further jackpot data.
