A gaming machine (100) may determine that a trigger event for a bonus game occurred during a base outcome event of a base game, wherein the base game and the bonus game are both reel-based games being executed on behalf of a client machine. In response, the gaming machine (100) may award use of two or more replaceable symbols (610; 702, 704, 706; 920, 922) for the bonus game. Until all of the replaceable symbols (610; 702, 704, 706; 920, 922) have been used, the gaming machine may repeatedly carry out iterations of bonus game operations including: determining a symbol set (600; 700) for display on a plurality of reels, where the symbol set includes non-replaceable symbols and zero or more replaceable symbols (610; 702, 704, 706; 920, 922), and where each displayed replaceable symbol (610; 702, 704, 706; 920, 922) is successively replaced in the display (110) by either a new non-replaceable symbol or a new replaceable symbol (610; 702, 704, 706; 920, 922) until no displayed replaceable symbols (610; 702, 704, 706; 920, 922) remain on the plurality of reels. |
