Abstract
A spinning reel slot machine which gives a multiplied payoff when certain conditions are fulfilled. Wins including a special symbol on the pay line are multiplied by an incremental multiplier when the machine is in a particular mode. A counter value is increased by one every time a second special symbol appears on the visible sections of the reels. Whenever the counter reaches a predetermined value, the counter is reset and the multiplier is increased. Whenever a multiplied payout occurs, the multiplier is reset to a minimum value.
