Abstract
An electronic gaming system includes at least one processor configured to provide a reel-based wagering game. In the game, a matrix of symbol positions is displayed, and during each spin of the reels, the processor determines whether at least one symbol displayed in the matrix is a target (or collectable) symbol. When at least one target symbol is displayed, the processor also determines whether a threshold number of such target symbols have been accumulated from the matrix by the player, and if so, the processor awards a plurality of free games, each of which is evaluated against an upgraded paytable. The upgraded paytable defines a plurality of upgraded awards for a variety of symbol combinations, at least some of which incorporate the target symbol. In some cases, a different (e.g., upgraded) version of the target symbol may be displayed during free games.
