It is a perspective view of the variable winning ball device 10. First, the basic operation of the variable winning ball device 10 will be described with reference to FIGS. 1 and 2.

When the pachinko game state becomes the specific game state, for example, when the display state of the variable display device described later becomes a so-called all 7 of "7, 7, 7", the variable winning ball device 10 is opened and closed. As shown in the drawing, the plate 12 is pivoted forward and opened, and the pachinko balls can be easily won in the winning opening 14, which is a first state advantageous to the player. When the variable winning ball device 10 is in the first state, the winning opening 14
When there are 10 pachinko balls that have won
When the time after reaching the state of 30 has reached 30 seconds, the opening / closing plate 12 rotates rearward, becomes flush with the surface of the mounting substrate 16, closes the winning opening 14, and moves to the winning opening 14. Is in a second state, which is disadvantageous to the player who cannot win the prize. Among the pachinko balls that have won the winning opening 14 while the opening / closing plate 12 is open, if there is at least one pachinko ball that has won a predetermined special prize area, for example, the central area, the opening / closing board 12 is opened again and variable. The winning ball apparatus 10 is in the first state, which is advantageous for the player, and the state continues until 10 pachinko balls are won or 30 seconds have passed, as described above. Then, the repetition of the above operation due to the pachinko ball winning in the special prize area is controlled to continue up to 10 times.
