The central playing surface includes an annular abutment wall arranged in surrounding relationship relative thereto to maintain marbles within the central playing surface. A modification of the invention includes a magnetic member rotatably mounted underlying the table and radially adjustable relative thereto to effect deflection of ferrous metallic marbles projected on the playing surface in cooperation with non-ferrous metallic marbles.
