PROBLEM TO BE SOLVED: To provide a slot machine which adds interest without excessively stirring up a player's gambling spirit by securing the player's high technical intervention in a bonus game as a special condition. SOLUTION: The slot machine 1 has a first high probability condition generation means 431 to generate a first high probability condition and terminate the first high probability condition when the number of winning games reaches a first specified number of games, a second high probability condition causing means 432 to generate a second high probability condition where the degree of advantageousness is lower than the first high probability condition and bring the second high probability condition to an end when the number of winning games reaches a second specified number of games. An internal drawing means 42 can permit a first-type small winning combination and a second-type small winning combination whose internal winning probability is higher than the first-type small winning combination to be internally won in the second high probability condition. A specific varying display section 21L sets a stop operation range corresponding to the second-type small winning combination to a narrower range than the stop operation range corresponding to the first-type small winning combination.
