A Ba-Gua game disk includes a disk having a flat dice area and a Ba-Gua area surrounding the dice area, a transparent enclosure placed on top of the disk and composed of an outer cover enclosing the Ba-Qua area of the disk and an inner cover integrally formed with the outer cover to enclose the dice area so as to separate the dice area from the Ba-Gua area, a dice movably and rotatably received in the dice area to randomly indicate a numeral from one to six and a ball movably received in the Ba-Gua area to be randomly rested on a corresponding one of the sections such that combination of location of the ball and the numeral of the dice represents a meaning.
