Abstract

In a slot machine, pay-out data about previous games that represent the relationship between a total number of inserted coins and a total number of paid coins, are stored and displayed. There is further provided a game simulation device which simulates the games that are intended to occur thereafter. The simulated games are repeated at a high speed with neither coin insertion nor coin payment, during which time the reels are not rotated. Hypothetical coin pay-out data are formed based on a total number of coins assumed to be paid out for the simulated games on the assumption that a predetermined number of coins were inserted for each simulated game. Also, the hypothetical coin pay-out data on subsequent games are displayed on request.
