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 special symbol (e.g., a $ symbol), initiates a special feature. Once the trigger event occurs, one of a plurality of features is randomly selected and applied to the symbols in the existing array of symbols, and an award is then granted based on the results. An example of the group of available features is: 1) multiply the number of $ symbols in the array by X credits; 2) randomly place a $ symbol on reels 1, 2, 4, and 5; 3) change certain predetermined symbols to the $ symbol; and 4) fill two, three, or four reels (randomly selected) with the $ symbol.
