To provide a Pachinko game machine which informs a player of a start of re-variation display with an interesting game effect.

If a symbol element (watermelon treasure box) is variably stopped at a middle stage of a middle variation area C, an image of a cloth appearing from the treasure box and an image of the cloth becoming from its initial size to a shielding size are displayed. This cloth covers each symbol element in the left variation area L and right variation area R at the shielding size. If the image of the cloth having the shielding size is displayed, images of the left variation area L and the right variation area R exposed in response to the movement of the cloth are displayed. In this image, symbol elements appear as a combination of an effect 1 in the left variation area L and right variation area R. If the symbol elements appear as a combination of the effect 1 in the left variation area L and right variation area R, re-variation display is started.
