PROBLEM TO BE SOLVED: To raise feeling of tension and to improve interest of a game, by judging a case, when a prescribed number of variable displays are done by a number prescribed at more than a number corresponding to the inverse of the special game condition generating probability after a special game start timing judgement, as the special game condition finishing timing. SOLUTION: When a prescribed condition is established, a game is made to be a special game condition which is different from a special game condition but advantageous for a player. For instance, an ordinary pattern variation time on an ordinary pattern display 14 is shortened. Thus the frequency of a movable piece 24 is made higher to make the prize probability higher. When a variable display 4 is displayed by a number prescribed at more than a number corresponding to the inverse of the special game condition generating probability, it is judged the finishing timing of the special game condition and the condition is stopped. Thus expectation for big prized generation is raised and feeling of tension and interest are improved. |
