Each of the second reels is aligned with one of the first display positions, and spins in a second direction to identify one of the prizes.

Abstract: A gaming machine having a number of reels. Each of the reels includes at least one special symbol that in either in an active state or a normal state. Each of the reels is in either a held state or a symbol collection state indicative of a number of special symbols currently collected. During a game, when the number of special symbols of a reel reaches a predetermined number, the special symbols on the reel are in an active state for a next play of the game. While in the active state, when a special symbol is selected for the reel, the reel is in a held state a subsequent play of the game.
