Various embodiments of a gaming system and method are disclosed as having secondary symbol sets that are used to enhance initial payout awards associated with winning symbol combinations. The gaming system may generate and display one or more symbols from the secondary symbol set in symbol display positions associated with symbols that formed a winning symbol combination. The generated symbols from the secondary symbol set and the symbols that formed winning symbol combinations can be displayed in the same symbol display positions at substantially the same time. In some embodiments, the symbols in the secondary symbol set comprise a plurality of different color symbols, where the color symbols are each associated with awards that may enhance a payout award associated with the winning symbol combination. Thus, generating the secondary symbols in association with the symbol display positions of the winning symbol combination may enhance or improve an initial payout award.
