The effect image is displayed at any time. That is, when the special symbol is changed by the special symbol display means 26, one or a plurality of, for example, three effect symbols 38a to 38c are variably displayed on the image display unit 34 in synchronization with the change of the special symbol. At this time, the effect symbols 38a to 38c change for a predetermined time through a predetermined effect symbol variation pattern determined by lottery on the condition that the special symbol start means 31 detects the game ball, and then synchronize with the end of the variation of the special symbol. Stop sequentially in a predetermined order (for example, left, right, middle, etc.).

  The stop symbol after the change of the effect symbols 38a to 38c is a jackpot effect mode in which all are aligned when the special symbol is stopped in the jackpot mode, and at least a part of the off symbol effect is different when the special symbol is stopped in the miss mode. It becomes an aspect.

  For example, numerical symbols from 0 to 9 are used for the production symbols 38a to 38c, and when the special symbols are stopped in a big win mode, the production symbols 38a to 38c are jackpot productions such as "7 / 7.7". When it stops in the mode and the special symbol stops in the off mode, the effect designs 38a to 38c stop in the off mode such as “2, 4, 5”.

  In the operation instruction of the rotary light emitting effect means 14, a predetermined game state that gives the player a sense of expectation, such as when a highly reliable effect symbol variation pattern in which the special symbol after variation becomes a big hit mode is selected, For example, when the two effect symbols 38a and 38c except for one effect symbol 38b become the same reach, an operation instruction image 39 for instructing the operation of the rotary light emission effect means 14 to a predetermined position of the image display unit 34. Is displayed.

  And, for example, when the special symbol starting means 31 detects a game ball, the jackpot is drawn out, and when the special game state occurs after the changed special symbol becomes the jackpot mode, the operation instruction image 39 If the light emission cover 14a of the rotary light emission effecting means 14 is pressed at an appropriate timing during symbol variation, the light emission part in the light emission cover 14a turns into a rotation light emission state that flashes and emits light. A special symbol will be stopped and the following special gaming state will be announced.
