Apparatuses and methods for facilitating participation in a gaming activity. A reel configuration of a plurality of reels is presented, where each of the reels includes one or more associated gaming symbols. The presentation of the gaming symbols is modified on the plurality of reels, such as by spinning the reels or otherwise changing which symbols are presented on the reels. A replacement reel is presented, to supersede or otherwise supplant at least one of the gaming symbols of the reel configuration. Results of the gaming activity are established using the gaming symbols of the plurality of reels and the replacement reel. The result is thereby based on a resulting presentation of symbols that includes both the symbols of the primary reel configuration and the symbol(s) of the replacement reel(s).
