<p><P>PROBLEM TO BE SOLVED: To provide a pinball game machine which can prevent drop in operation rate with raising expectation in players for the winning by raising the probability of acquiring the random number values to match the updated cycle of the winning random numbers. <P>SOLUTION: Pachinko balls winning the starter slot in the storage mode flow downward on the second path 20b. The downward flow of the pachinko balls is blocked with a shutter 25 in the second path 20b. As a result, the pachinko balls are stored on the second path 20b, and the number of the pachinko balls stored is counted. When the number of pachinko balls stored reaches four, the shutter 25 moves to the release position from the storage position. As the shutter 25 moves to the release position, the game balls stored flow down to the downstream side of the second path 20b and are detected sequentially with a release sensor 27. Each time four pachinko balls are sensed with the release sensor 27, the winning lottery is carried out sequentially four times. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
