Abstract: An electronic gaming device comprises a display and a game controller. The game controller sets a count limit for each reel bearing special symbols, the special symbols being borne by up to m?1 reels of a first set of reels. For each base game round, the game controller selects a plurality of symbols. For each occurrence of the special symbol within the displayed symbols, for the reel on which the special symbol appears, control the display to display an increment of a counter up to the count limit for the reel, wherein the count persists for the base game rounds. For a feature game round, the game controller further performs a wild reel substitution for each reel where the reel count satisfies an eligibility criterion to provide a second set of reels. A visual indicator of increased opportunities to win may be displayed for each established extended wild reel eligibility.
