Abstract: The present invention is a gaming device having a secondary game played in conjunction with a symbol-matrix base game. The symbol-matrix game includes a special designation symbol within the symbol set associated with the base game. Occurrences of the special designation symbol in the symbol-matrix base game are spatially re-represented in a secondary matrix that is a mirrored representation of the symbol-matrix from the base game. Through a series of plays of the base game, the occurrences of the special designation symbol accumulate until a pre-determined pattern is established in the secondary matrix indicating a winning outcome of the secondary game.
