Methods, apparatus, and program products provide for dynamically modifying a symbol matrix, such as a symbol matrix produced in a reel-type game, to provide the player with additional chances to win on a given activation of the game. In particular, one or more initial symbol locations in a matrix of symbol locations may be split so as to replace the respective initial symbol location with two or more symbol locations. The additional symbol locations produced in this way define additional sets of symbol combinations and these additional symbol combinations provide the player with additional chances to win on a given play of the game.
