PROBLEM TO BE SOLVED: To provide a slot machine which can control rotation of a rotary reel with 20 symbols by using a stepping motor for rotating a rotary reel with 21 symbols, shares members, and can reliably observe conditions imposed on a stop time of the rotary reel.SOLUTION: In a slot machine 10 provided with a stepping motor 26 where 21×N steps (N is a multiple of 4 equal to or larger than 16 excluding a multiple of 5) are set as the total number of steps, 20 symbols 51 are attached to a rotary reel 25. When a quotient after dividing 21×N steps set as the total number of steps by 20 is M and the remainder is P, P/4 symbols 51 to which M+1 steps are assigned and (20-P)/4 symbols 51 to which M steps are assigned are included within any of ranges of consecutive 5 symbols 51 among the 20 symbols 51. |
