Claims (2)

Display means for displaying a symbol variation game performed by varying a plurality of symbols, start winning means for giving a starting condition for the symbol variation game, and whether or not a game ball wins the start winning means A lottery means for performing a winning lottery determined by a lottery and a winning means for releasing during a winning game, and when winning the winning lottery, a winning display indicating the occurrence of the winning as a display result of the symbol variation game In a gaming machine in which a result is displayed and then a winning game is performed to release the winning means,
The winning game is given when the lottery means determines the first winning game, and when the lottery means determines the second winning game, the winning game is more than the first winning game. A mode in which the player cannot discriminate the difference between the second winning game in which the maximum number of times the winning means is opened and the lottery means determines the third winning, and the difference between the second winning game and the second winning game. And a third hit game that opens the winning means.
Said selecting means, based on the lottery result of the per drawing, the determination of the first per and first hit judging and the first collision determination determines whether won per formed of the second per If the result is negative, a second hit determination is made to determine whether or not the third hit is won. If the determination result of the first hit determination is affirmative, the first hit and the first hit are determined. It is determined which hit of the second hit, the second hit determination is performed with a winning probability higher than the winning probability when the determination result of the first hit determination is affirmative,
In the case of winning in the first win, the game state after the winning game based on the first win is changed to a probability fluctuation state in which the winning probability of the first hit determination in the lottery means changes from a low probability to a high probability. In the case of winning the second hit, the winning probability of the first hit determination in the lottery means is low as the gaming state after the winning game based on the second hit If the winning state is determined based on the third win, the game state after the winning game based on the third hit is the same as the gaming state at the time of winning the third win. Gaming state determining means for determining the gaming state of
A special mode for concealing whether or not the gaming state after the winning game is a probability variation state is set after the winning game based on one of the second and third winnings , and based on the special mode. A concealment effect execution means for executing the concealment effect;
Wherein said by 2 per and the arrival of the mode setting timing of setting the special mode in response to any of the winning of the third per second per and setting timing determining one of whether the player wins the third per A determination means;
Said mode setting when the arrival of a trigger, a and a determining gaming state determining means for determining whether any of the game state when winning the second per and the third per is the probability change state,
A plurality of types of the special modes are prepared, and the plurality of types of special modes are ordered according to the probability that the probability variation state is given,
When the mode setting opportunity arrives during the gaming state in which the special mode is set, the concealment effect executing means is given the probability variation state more than the special mode set at the time of the mode setting opportunity. If the special trigger mode is selected, and it is determined by the setting trigger determination means that the second win is won, the probability is higher than when the third win is won. It is easy to select a special mode in which the possibility that a fluctuation state is given is large, and the probability fluctuation state is given when the gaming state determination means determines that the probability fluctuation state is present. It is easier to select a special mode that is more likely to be in the probability variation state than when it is not. The concealment effect execution means, when the game state is not a probability variation state and the mode setting opportunity has arrived during the normal game state in which the special mode is not set, among the special modes, the probability variation state 2. The gaming machine according to claim 1, wherein a special mode that is least likely to be selected is easily selected.
