Abstract
A gaming device including a plurality of reels, where in an unlimited free spin mode, the gaming device causes at least one of the reels to lock or remain stationary when a locking symbol appears on that reel. At least one of the symbols on the reels is associated with each of the unlocked reels. The gaming device enables a player to pick at least one of the symbols associated with the unlocked reels to determine a modifier. The gaming device activates at least one of the unlocked reels for a number of additional free spins. Each time the selected symbol occurs on at least one of the reels, the gaming device changes or increments the value of the modifier. When there are no additional free spins remaining, the gaming device modifies any awards obtained by the player in the additional free spins by the modifier to provide the player with a modified award.
