<P>PROBLEM TO BE SOLVED: To provide a slot machine which can validate one of setting values in two or more stages and can appropriately set the difficulty of predicting the setting value. <P>SOLUTION: The slot machine 1 includes: a specific performance probability defining means 332 for defining a first execution probability of a large difference of the respective setting values and a second execution probability of a small difference of the respective setting values; a specific performance determination means 45 for determining whether or not to execute a specific performance by one of the first and second execution probabilities; an operation data sum-up means 48 for summing up operation data; an operation determination means 461 for determining whether the operation data are equal to or more than a reference value or less than it; a setting value determination means 462 for determining whether the setting value is more advantageous or disadvantageous than a predetermined reference setting value; and an execution probability selection means 47 for selecting an execution probability to be applied to the specific performance determination means 45 according to the combination of whether the operation data are equal to or more than the reference value or less than it and whether the setting value is more advantageous or disadvantageous than the reference setting value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
