Abstract
A gaming device including a free activation mode having a predetermined number of free activations wherein the probability of extending the free activation mode is increased by a triggering event which triggers an unlimited number of free activations. A termination event terminates the unlimited fee activations. A freezing event freezes the number of remaining free activations. A resetting event resets the number of remaining free activations. A locking event causes at least one symbol or at least one card to remain unchanged or lock during the unlimited free activations. The gaming device generates a plurality of symbols while not changing the locked symbol or re-deals the remaining cards an unlimited number of times until a termination event occurs.
