• at least one display device associated with at least one of said gaming devices;
• and
• at least one controller configured to operate with each of said gaming devices and said at least one display device to:

• (b) determine a second, different rate that a second player at a second of said gaming devices is placing wagers on plays of a second primary game for the designated period of time;
• and
• (c) if a bonus event triggering condition occurs and the first player and the second player have each wagered a same designated amount for the designated period of time:
