Abstract
Disclosed herein is a game played on a gaming device that displays a randomly selected array of symbols, where the symbols across one or more paylines are evaluated by circuitry to determine an award to be granted. A trigger event, such as the occurrence of a certain plurality of special symbols, initiates a series of free games. The number of free games and an award multiplier associated with each free game are dependent on the particular type of special symbols making up the trigger event.
