Abstract

A gaming machine is described herein. The gaming machine includes a display device for displaying a game and a controller connected to the display device. The game includes a plurality of reels, each reel having a reel strip including a plurality of symbol positions and a plurality of game symbols displayed in each of the symbol positions in a predetermined order. The controller is configured to determine an outcome of the primary game, responsively spin and stop the reels to display the outcome of the primary game, and provide a first award to the player based on the primary game outcome. The controller detects if a triggering graphic is being displayed with the primary game outcome and is associated with at least one reel, modifies a reel feature of a reel strip associated with the reel, and generates an outcome of a secondary game including the modified reel strip.
