Next, an operation of the auxiliary accessory 8 having the above configuration and a control example performed by the control device will be described.

First, in the variable display based on the winning of the special symbol starting port 3, the same big three symbols will be displayed as a jackpot, and when the special game by the jackpot is completed, the control device is in the first posture until then. The rotating body 82 that has been stopped and waited for is rotated. Thereby, the rotating body 82
Rotates at a constant speed in the direction of the arrow in the figure. On the other hand, when the game ball passes between the obstacle nails 17 and enters the ball introducing port 8a, and further enters the ball engaging portion 82a in the vicinity of the first posture, this game ball is engaged with the rotation of the rotating body 82. It is rotated by about 180 degrees while being held by the portion 82a and the ball support wall 82b, released from the ball engaging portion 82a, and drops through the ball passage port 83. The passage of the game ball is detected by the ball detector 83a, and the passage detection signal is sent to the control device.

When the passage detection signal is input, the control device controls the game mode based on the passage detection signal and converts the game mode from a disadvantageous mode to an advantageous mode for the player. Then, when the passage detection signal is input again next time, the game mode is changed from a mode advantageous to the player to a disadvantage mode. That is, the game mode is switched each time the passage detection signal is input. Then, this game mode switching control is performed for a predetermined period, for example, a period until the variable display based on the winning in the special symbol starting port 3 is performed 10 times, and the rotating body 82 is provided at the time when the variable display is made 10 times. The rotation of is stopped in the first posture and kept waiting.

Among the above-mentioned game modes, a mode that is disadvantageous to the player is a game state in which the probability of being a big hit is a normal low probability, and the game is advanced with the low probability, and the mode advantageous to the player is The jackpot probability is set to be higher than usual, and the gaming state is advanced with the high probability. The control device switches the jackpot probability to one of two modes, high and low.

FIG. 3 is a flow chart of control performed by the control device in connection with the auxiliary accessory according to the present invention.

First, in step S1, it is judged whether or not the special game is completed, and if it is completed, the next step S
Proceed to step 2, and if not completed, end this program.

In step S2, rotation of the rotating body 82 is started, and the process proceeds to the next step S3.

In step S3, it is determined whether or not the game ball has passed through the ball passage port 83, and if it has passed, the process proceeds to the next step S4, and if it has not passed, step S4.
Skip to 5.

In step S4, if the current probability of being a big jackpot is a normal low probability, the probability is switched to a high probability, and if it is high, it is switched to a normal low probability, and then the process proceeds to step S5.

In step S5, it is determined whether or not the variable display based on the winning in the special symbol starting port 3 has become 10 times, and if it has reached 10 times, the process proceeds to the next step S6.
If not, the process returns to step S3, and steps S3 and S
4 and S5 are repeatedly executed.

In step S6, the rotation of the rotating body 82 is stopped in the first posture, and then this program ends.

As described above, in the embodiment of the present invention, each time the game ball held by the ball engaging portion 82a of the rotating body 82 passes through the ball passage port 83, the game mode becomes advantageous to the player. Since the game mode is switched so as to be disadvantageous, even when the game ball is held by the rotating body 82, the subsequent development is not uniform and the variation is rich. Then, the player always pays attention to whether it is advantageous or unfavorable for him to hold the game ball on the rotating body 82, and puts the game ball into the rotating body 82 in anticipation of an advantageous time. . Therefore, the player feels nervous in the development, and the interest as a game is greatly enhanced.

In the above description, as the switching of the game mode, the probability of being a big hit is switched to one of two modes, high and low, but this switching of the game mode is performed with respect to any other game mode. Can be similarly applied. For example, the probability that the normal symbol display device 51 will hit may be switched to one of two modes, high and low, and the variable display time until the symbol stops in the normal symbol display device 51 is either long or short. Alternatively, it may be switched to. In addition, the electric accessory 300
The opening time for continuing the second state in which the rotary wing piece 301 tilts and opens to facilitate the entry of a hit ball may be switched to one of two modes, long and short. Furthermore, the number of prize balls at the winning opening 9 and the large winning opening 41 in the special game state
The number of prize balls in 1 may be switched to one of two modes, that is, the number of normal prize balls and the number of prize balls twice the normal number.

Further, in the above description, the rotation of the rotating body 82 is started at the time when the special game is completed, and then the rotation is stopped at the time when the variable display based on the winning of the special symbol starting port 3 is made 10 times. However, the rotation start and rotation stop of the rotating body 82 may be performed in any other game state. For example, the rotation start time is
When the special game starts, an intermediate time until the special game starts and is completed, a display mode according to a display mode in which the variable display based on the winning of the special symbol starting opening 3 is a big hit,
That is, when the reach mode is reached, the special symbol starting port 3
When the variable display based on winning a prize is given a predetermined number of times,
The time when the variable display based on the winning of the special symbol starting opening 3 becomes a predetermined symbol aspect can be adopted. Also, as the rotation stop timing, the time when the special game starts, the time when the special game is completed, the time when the variable display based on the winning of the special symbol starting opening 3 becomes the reach mode,
When the variable display based on the winning to the special symbol starting port 3 is made a predetermined number of times, the variable display based on the winning to the special symbol starting port 3 becomes a predetermined symbol mode, the rotating body 82
When the number of revolutions reaches a predetermined number of revolutions, when the game ball passes through the ball passage port 83 and is detected by the ball detector 83a, etc., it is possible to adopt the above-mentioned respective timings of rotation start and rotation stop. By combining, it is possible to set an appropriate rotation period.

In the above description, the auxiliary accessory 8 is composed of the rotating body 82 and the ball passage opening 83, but the auxiliary accessory 8 may have various other configurations. For example, an obstacle that operates so as to prevent the game ball from passing through the ball passage port is provided above the ball passage port and driven by a solenoid, and the game ball is passed or not passed by turning the solenoid on and off. It may be configured. Also,
The ball passage opening itself may be movable by a solenoid. Further, it may be configured with a ball passage opening, and the validity or invalidity of the passage may be determined by a software program.
