A gaming machine for conducting a wagering game includes a display for displaying three or more reels, one having at least one triggering symbol representing a guaranteed award when it lands along an active payline selected by the player. When the triggering symbol lands along the selected payline, resulting in a triggering outcome, a corresponding outcome is retrieved from a table containing mappings of each triggering outcome with a corresponding outcome. The table is predetermined such that at the time the triggering outcome is presented to the player, the outcome is preordained. The outcome can further include another triggering symbol, in which case that winning outcome is further mapped to a retriggered winning outcome. In addition to mapping to each triggering outcome with a outcome, each outcome can be mapped to a game enhancement parameter.
