<p><P>PROBLEM TO BE SOLVED: To prevent decision on whether control to a predetermined game state should be performed or not by a numerical value extracted at timing different from the timing at which a start condition is effectively established. <P>SOLUTION: When a game ball enters a first start winning port or a second start winning port, a random number is fetched to a random number value register provided for each start winning port regardless of whether the start condition is established or not on the basis of the entry. The random number value register does not fetch any new random numbers until the random number fetched once is read. Whether or not the random number is fetched to the random number value register for each start winning is monitored each time when game control timer interruption processing is executed. When a monitoring result that the random number has been fetched is obtained, the random number is read from the random number value register and is stored in a predetermined random number read section. On entry of a game ball and establishment of the start condition including a condition that a holding storage number does not reach an upper limit number, the random number for determining the result of a special symbol game is acquired from the random number read section. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
