The central server monitors wagers on the gaming machines. Based at least in part on the wagers the central server determines when bonus events will occur and which gaming machine(s) will provide the bonus awards. In one embodiment, the central server determines which gaming machine will provide a primary bonus award and any secondary bonus awards. In one embodiment, the number of secondary bonus awards is determined based on the number of active gaming machines. The selected gaming machine then determines a component of or the amount of the bonus award to be provided to the gaming machine selected by the central server. ## Claims ### Claim 1 A gaming system
