A wagering game having a primary game and a secondary game. In one embodiment, an intermediate game outcome for the primary game is first determined. The intermediate game outcome provides the player with an indication of the probability of receiving a winning primary game outcome. The player may then use this indication for determining whether to play the secondary game. The optional secondary game, if won, modifies the play of the primary game to the advantage of the player. Consequently, the intermediate game outcome is resolved to determine the primary game outcome in accordance with the modified primary game. If the secondary game outcome is lost, the immediate game outcome is resolved to determine the primary game outcome without modifying the primary game.
