<p>An objective of the present invention is to provide an improved top board in which a plurality of inclined portions are formed in a top movement path and a collision is generated through a rapid top movement so that a top battle can become fun, and popping of the top to a user after inter-top collision and deviation is prevented. The present invention includes a concave inclined portion; side wall portions that protrude at a predetermined gap at a circumference of the inclined portion so as to prevent top deviation; and an opening portion that is open between the side wall portions and allows any colliding top to deviate from the inclined portion when a collision occurs between the rotating tops. The inclined portion has a dual structure having a first inclined portion forming an inclined angle and a second inclined portion having an inclination angle larger than the inclination angle of the first inclined portion. Accordingly, a plurality of the inclined portions are formed in the top movement path, a rapid top movement and collision can occur, and a top battle can become fun.</p> |
