During a play of a game, the disclosed gaming system determines that an ending condition has occurred. For example, the gaming system determines that an ending condition has occurred when no winning symbol combinations are displayed for the play of the game. Following determination that the ending condition has occurred, the gaming system determines whether to provide access to an additional win opportunity for the play of the game. If the additional win opportunity is to be provided, the gaming system removes one or more symbols from a plurality of symbol positions even though such symbols do not form a winning symbol combination. The gaming system fills any resulting empty symbol positions by shifting symbols and/or displaying generated symbols, and provides awards for any then-generated winning symbol combinations. The additional win opportunity may be accessed because of a player wager or because other additional win opportunity criteria are satisfied.
