The present invention provides a novel bonusing system implemented on gaming machines and associated network devices on a network. According to some implementations, a central system qualifies or eliminates sites and/or types of gaming devices for participation based on criteria such as contribution level, games available, date range, location, device manufacturer, denominations available, etc. In some implementations, the qualification or elimination process is performed at a site (e.g., by a site controller) according to criteria obtained from the central system. The methods of the present invention may be de-coupled from player tracking methods.
