<P>PROBLEM TO BE SOLVED: To provide a game machine which can keep the continuity of game, increase a player's expectation for a big winning, and also keep thrill and excitation for a long period. <P>SOLUTION: When a ball enters in a special prize winning hole 12, a random number lottery having possibility to produce a big prize or a semi-prize is performed. When a result of the lottery is a semi-prize, a ready-to-win condition pattern that has only one symbol different from a big win pattern, is displayed in a variable display means 20. Further, in the semi-prize winning condition in the pattern matching game which is performed when a ball enters to the special prize winning hole 12 in the game rounds repeated thereafter, a pattern change limiting means 70 prevents the common symbols of the pattern in the ready-to-win condition patterns already displayed from being changed. For example, in the case that '777' is the big win pattern, and '767' that is a ready-to-win condition pattern of semi-prize is won, only a central digit symbol '6' is changed and the other symbols remain unchanged, in the pattern matching games repeated thereafter. <P>COPYRIGHT: (C)2003,JPO |
