SLOT MACHINE

PROBLEM TO BE SOLVED: To prevent fairness of a game from being harmed even when stop switches are operated on the basis of a contradictory report that a special combination is won though it is not really won.SOLUTION: When the stop switches 42 are operated in a specified operation order when the combinations of "PB=1" and "PB≠1" are redundantly won, a symbol combination corresponding to the combination of "PB=1" is stopped on an effective line. In a game in SBB or NBB, when the combinations of "PB=1" and "PB≠1" are redundantly won, the specified operation order of the stop switches 42 is reported, and the contradictory report that RB is won is performed. Thereafter, in a game in which a symbol combination corresponding to SBB or NBB can be stopped on the effective line, an appropriate report that SBB or NBB is won is performed before the first stop switch 42 is operated.
