Abstract
According to the present invention, a wildcard symbol is provided at a stop position of one of the reels in a typical reel-type slot machine. In addition to the usual spin and payoff cycle of such a machine, the appearance of the wildcard on the pay line is used to trigger a supplemental pay off under certain circumstances. During the supplemental pay off sequence, the reel on which the wild symbol appears is caused to shake or jitter while coins fall into the trough as if money were being shaken off a tree.
