Abstract
According to a gaming machine of the present invention, a specific number of free games are generated when three or more trigger symbols have been stop-displayed in a normal game. Further, when one or two trigger symbols have been stop-displayed in a free game, numeric values in number equivalent to the number of stop-displayed trigger symbols are selected, and then the number of times obtained by summing up the selected numeric values is added to the number of free games.
