Abstract

A gaming system including a central server linked to a plurality of gaming machines and a plurality of bonus awards. 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, wherein at least one gaming machine may be provided a plurality of bonus awards.

14. The gaming system of claim 1, which includes an accumulated wager pool which includes at least the total amounts of the wagers placed on the primary games of all gaming machines during the bonus event accumulation period.

15. The gaming system of claim 1, wherein a processor of one of the gaming machines functions as the controller.

16. The gaming system of claim 1, wherein at least two of said primary games of at least two of the plurality of gaming machines are different.

17. The gaming system of claim 1, wherein the bonus event is an award.

18. A gaming system comprising:

a plurality of gaming machines, each gaming machine including a primary game operable upon a wager placed by a player; and

a controller in communication with said gaming machines, wherein the controller is programmed to determine if a bonus event will occur, and if the controller determines that the bonus event will occur, said controller is programmed to;

(a) determine a quantity of said gaming machines to participate in the bonus event, said quantity being greater than one;

(b) determine which of the gaming machines were in an active state during a bonus event qualification period for said bonus event;

(c) for each gaming machine in the active state, determine a probability to participate in the bonus event based on the total wagers placed during a bonus event accumulation period for said gaming machine relative to the total wagers placed for all gaming machines in the active state during the bonus event accumulation period;

(d) select one of the gaming machines in the active state to participate in the bonus event, wherein said selection is based on the determined probabilities to participate in the bonus event;

(e) determine if the determined quantity of gaming machines to participate in the bonus event has been selected; and

(f) if the determined quantity of gaming machines to participate in the bonus event has not been selected, repeat (d) to (f) at least once, wherein at least one of the gaming machines is operable to be selected a plurality of times, even if said gaming machine was previously selected to participate in the bonus event.

19. The gaming system of claim 18, wherein a plurality of the gaming machines are each operable to be selected a plurality of times even if said gaming machine was previously selected to participate in the bonus event.

20. The gaming system of claim 18, wherein each of the gaming machines is operable to be selected a plurality of times even if said gaming machine was previously selected to participate in the bonus event.
