A spinning top system, comprising a plurality of spheres, each sphere having a center. The spinning top are arranged according to one of several geometric formations, including a tetrahedron, octahedron, icosahedron, cube octahedron, and a hexagon, each of said geometric formations having several vertices. The spheres of the spinning top are arranged according to the particular geometric formation, wherein each vertice of the geometric formation corresponds to the center of one of the spheres. Arranging the spheres in this manner creates an symmetrical spinning top, which is capable of balancing and spinning upon one of these spheres. The spinning tops are also capable of stacking to form a stack of considerable height.
