To enable a user to make a battle game or shooting game with a top given rotating power by providing the centers on both flanks of the top with apertures, inserting joint pieces of both from both flanks and fitting both joint pieces within the top.

The top 1 is formed of bisected hemispherical bodies 1a, 1b. A revolving shaft 8 is mounted in the central part of the flank of the one hemispherical body 1b. The centers on both flanks of the two hemispherical bodies 1a, 1b are provided with the respective apertures 1c, 1d. Both joint pieces 11 of a projecting part and a recessed shape are inserted from the respective apertures 1c, 1d and are fitted to each other in the central part on the inner side of the top 1. When the joint is released in a perpendicular direction, the user is able to make play as the rotating top 1. If the outer peripheral shape of the top 1 is formed as a polyhedron, the user is able to spring out the opponent's top 1 at the time of the battle game. When the joint is released powerfully, the top 1 jumps and travels while rotating and, therefore, the user is able to make play as the shooting game to a target.
