A display grid includes a plurality of grid positions that are presented to a game player. One or more grid positions of the plurality of grid positions are defined as termination positions. One or more wild symbols are moved to grid positions proximate the grid positions associated with the one or more wild symbols using a random process. Winning results are determined using a pay table, based on both the one or more wild symbols and the symbols presented at the grid positions not associated with the one or more wild symbols after a spin. Random movement of the one or more wild symbols to grid positions proximate the grid positions associated with the one or more wild symbols is repeated until the one or more (or all) wild symbols move to the termination positions.
