Abstract

The preferred embodiment of the present invention operates on a system of interconnected gaming machines and selectively provides one or more active features to all of the gaming machines linked to the system. The enablement of the feature may be based on the combined results from previous plays on the individual gaming machines. The feature may be a bonus award for a specific displayed combination, an increased possibility for a winning combination, or any other feature which alters the normal operation of the gaming machines. The first machine to generate a winning game result to which the feature applies will be given an award based upon the feature. The feature is then disabled and the system returns to normal play mode until the feature is again enabled. Various other features are described.
