A system and method for facilitating participation by a player in a bonus event of a slot machine. A reel configuration associated with the slot machine is presented, and symbols are presented in each of the active reel segments. At least some of the symbols are discontinue symbols which, if presented in an active reel segment, causes that reel segment to be deactivated, thereby eliminating it from the bonus event. The presentation of symbols and subsequent deactivation of symbols associated with discontinue symbols continues until a predetermined number of the active reel segments have been deactivated.
