(54) Slot machine with pattern-driven award feature


(57) A pattern-based award system for a slot machine. In one embodiment, a basic payoff is made if a symbol group displayed on the slot machine includes a basic winning combination and a supplemental payoff is made if the basic winning combination matches a target pattern. In another embodiment, an enhanced payoff is made if the symbol group displayed on the slot machine includes a basic winning combination which matches a target pattern; otherwise, a basic payoff is made if the symbol group includes a basic winning combination which does not match the target pattern. The basic payoff in each embodiment comprises a predefined amount of coin(s) or credit(s) or a randomly selected mystery amount. The supplemental or enhanced payoff is the product of the basic payoff amount and a randomly selected mystery multiplier.
