<p><P>PROBLEM TO BE SOLVED: To provide a game machine capable of changing the probability of giving a privilege to a player for making a game interesting. <P>SOLUTION: In the game machine 10, a plurality of pattern lines 85, 86 and 87 are variably displayed by pattern displays 21, 22 and 23 when a game medium is captured and a starting operation part 61 is operated. When stop operation parts 62, 63 and 64 mounted for each pattern line are operated and all the patten lines are stopped, a pattern combination is stopped/displayed and a round of game is terminated. At this point, it is determined whether the probability of giving the privilege should be changed or not based on a prescribed opportunity. The prescribed opportunity comes whenever a prescribed number of rounds of game are executed. Since the prescribed opportunity for determining whether the probability of giving the privilege should be changed or not comes whenever the prescribed number of rounds of game are executed, the player can know after how many rounds of game the determination to change the probability of giving the privilege will be made. As the time to determine the change of the probability of giving the privilege approaches, the player's expectation for a higher probability as the result of the determination is enhanced, so that the player can play the game pleasantly. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
