PROBLEM TO BE SOLVED: To perform a control so as to generate a winning by a shot ball image as randomly as possible in an image display type game machine so as not to loose the interest in a game. SOLUTION: Each shooting ball by an image in which winning/non-winning is preliminarily determined is temporarily arranged. A data forming an index is determined on the basis of a prescribed operation. A standard shooting pattern is set to (3, 5, 1, 2, 4), and the numerical value in the standard shooting pattern is replaced by use of the index. The numerical value in the standard shooting pattern shows the shooting order of the temporarily arranged shooting balls. |
