(I) Normal time The winning probability of the normal electric starting opening 63 is controlled so that there are three starting winnings for every 100 balls fired. Specifically, the winning rate is controlled by properly using the winning probability of 1/3 and the random number of 1/30. (II) High probability The winning probability of the normal electric starting opening 63 is controlled to 1/3. Therefore, there is one starting prize for every three shots of the ball, and the player is in an extremely advantageous state and the game becomes interesting.

A. Conditions under which the probability of winning a prize changes: After the big hit of the center accessory device 62, whether it becomes a high probability by using one of the following six-stage probability values set by a probability setting device (not shown) To decide. In addition, when the next big hit occurs in the high probability, it returns to the normal probability. In addition, the normal probability is adopted during the big hit.

B. Probability setting value The probability value that the probability of winning the Poden prize changes to a high probability is as follows.
There are stages. [6] …… 17/32 [5] …… 13/32 [4] …… 10/32 [3] …… 7/32 [2] …… 5/32 [1] …… 3/32

The above six-step fluctuation probability values are changed in advance by a probability setter, for example, by a clerk before opening a hall.
It is set (that is, one of six stages is set).
Since this probability setting is important, a locking device is provided for sealing, and the probability is set by the staff of the hall inserting a predetermined key into the key insertion port. Therefore, the player is not easily touched from the outside, and the probability value cannot be seen from the outside.
