Abstract
Periodic prize draws are conducted by a jackpot controller (13) in a gaming system having one or more electronic gaming devices (10), where the probability of each electronic gaming device winning a particular prize draw is dependent upon the amount wagered on that gaming machine during a determined period of time preceding that prize draw. The prize can be a progressive jackpot with an initial value that is increased by contributions from the amounts wagered on the electronic gaming devices.
