The invention provides a child game floor mat which comprises a first floor mat unit and a second floor mat unit. When the spliced floor mat is flatwise placed on the ground, the surface attached to the ground serves as the first surface, and the surface opposite to the first surface serves as the second surface, the portion simultaneously comprising the first surface and the second surface serves as a floor mat main body, the floor mat main body further comprises the third surface intersected with the first surface or the second surface, and the first surface of the floor mat main body extends far away from the floor mat main body to form bonding areas. The bonding areas of the first floor mat unit are provided with convex portions, and the bonding areas of the second floor mat unit are provided with concave portions; the bonding areas are provided with splicing areas, the splicing areas can be simultaneously spliced with multiple floor mats during splicing, and the splicing areas are closely attached to the splicing areas of the adjacent same-type floor mat unit. Compared with an existing floor mat, the child game floor mat has the advantages of being convenient to splice and not prone to loosen after being spliced.
