JACKPOT CONTROLLER AND A METHOD OF PROVIDING A JACKPOT FOR A GAMING MACHINE

摘要

The invention generally relates to gaming machines and methods implemented with use of a gaming machine. A prize awarded on a gaming device is awarded by obtaining a turnover value for at least one gaming device over a period of time, calculating a probability value based on the turnover value and using the probability value to determine whether the prize is to be awarded. In some implementations there may be two prizes that are awarded with different probabilities when the gaming machine system is in different configurations.
