A game projectile is configured as a polyhedron rather than being spherical or cylindrical in shape. The projectile is independently supported above the low friction base by which it moves across the playing surface. Provision may be made to permit the polyhedron to rotate about its independent supp
Apparatus in which a movable piece is projected across a playing surface comprising a polyhedral projectile; and low friction means for moving said polyhedral projectile across said playing surface coupled to said polyhedral projectile such that a vertical axis of symmetry of said low friction movin
