PROBLEM TO BE SOLVED: To effectively improve the interest in a game where the level of the degree of difficulty of continuation is variable.SOLUTION: During a set continued after going through a continuation lottery performed with lowest winning probability of a used continuation rate table, an additional lottery based on winning probability higher than winning probability in an additional lottery during the preceding set can be performed. Therefore, a benefit where the additional lottery is easy to be won can be imparted to a player having achieved continuation having the highest degree of difficulty of the used continuation rate table as the counter value thereof. Thus, the counter value can be imparted to the achievement of the continuation having the especially high degree of difficulty, so that the interest in a game where the level of the degree of difficulty of the continuation is variable can be effectively improved. |
