PROBLEM TO BE SOLVED: To effectively enhance interest in a game by changing an expectation to an advantageous game state.SOLUTION: The number of probability variation times that becomes a period where a control to a probability variation mode is made is designed to have a structure in which an addition is made, by a lottery winning of a BN symbol combination during a high probability RT game, to a number of ART progressed times relevant to the high probability RT game as an object. In this way, at a vicinity to the start of the high probability RT game and that is in a state where residual number of game times are left more than at a vicinity to the end (near to 30 times), a state can be created where a variation game can be played without anxiety. On the other hand, at a vicinity to the end of the high probability RT game (near to 30 times) and that is in a state where the number of progressed game times is more accumulated than at a vicinity to the start, a state can be created where an addition to the number of probability variation times can be expected. Accordingly, even during the high probability RT game, since the number of progressed game times that changes by a timing at which the BN symbol combination is won in the lottery is added to the number of probability variation times, interest in the game during the high probability RT game can be effectively enhanced while changing an expectation to the high probability RT game. |
