<p><P>PROBLEM TO BE SOLVED: To enable the winning of a special symbol game with more game balls obtainable in the variable probability and time shortening state by differentiating the number of game balls obtainable between two special symbol games when both of the games are won separately. <P>SOLUTION: The game machine has the first starter prize winning slot 51 that allows game balls to win it anytime and the second starter prize winning slot 55 that enables the winning of it only when the ordinary variable prize winning device 53 is opened. When a game ball wins the first starter prize winning slot 51, the first special symbol game with less prize balls obtainable is carried out. When the second starter prize winning slot 55 is won by another game ball, the second special symbol game with more prize balls obtainable is carried out. The variable display time of the first special symbol game is made longer under the variable probability and time shortening states which make the second symbol game easier to conduct by frequently opening the ordinary variable prize winning device 53 so that the game balls may win the second starter prize winning slot 55 during the period. This enables the starting of the second special symbol game made preferential to the first special symbol game thereby achieving the winning of the second special symbol game as much as possible. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
