Wagering game for implementing game-enhancement parameters with a guaranteed bonus

摘要

A gaming terminal is utilized for playing a wagering game. A wager-input device receives a wager from a player. A display displays symbols indicating a randomly selected outcome selected from a plurality of outcomes. The plurality of outcomes include at least one special-event outcome that awards additional game play at a time selectable by the player. The additional game play provides a guaranteed winning outcome. A special-event input device initiates the additional game play in response to the player activating the special-event input device. The additional game play is implemented with a game-enhancement parameter such that the guaranteed winning outcome has an enhanced payout.
