PROBLEM TO BE SOLVED: To eliminate mannerism of a game by achieving a novel technique as a technique to raise expectations with respect to generation of a big winning, and to improve operation rate.SOLUTION: When entering a lottery period (S711:Yes), a random number is acquired from a counter for a specific video image lottery (S713), and a current holding number U1 of special symbols and a big winning determination result are read (S714, S715). In the case of the big winning (S716:Yes), a lottery table at the time of the big winning is referenced (S717). When the random number acquired in the S713 exists as a random number corresponding to the holding number U1 of special symbols in the lottery table at the time of the big winning (S719:Yes), a special video image is displayed (S720). If the specific video image having a high probability to be displayed when the holding number U1 of special symbols is large is displayed when the holding number U1 of special symbols is small, the degree of expectation with respect to generation of the big winning becomes high. |
