  • Gaming machine
    Publication number: 20030207709
    Abstract: A gaming machine adapted to display and operate a base game 10 (such as a spinning reel type poker machine), and a feature game 15. The operation of the feature game 15 does not rely on any triggering outcomes in the base game 10. The random occurrence of a predetermined trigger 16 in the feature 15 causes an adjustment to the outcome in the base game such as the substitution of particular symbols on the reels for wildcards.
