    Abstract: Apparatus is provided for the playing of a parlor game version of baseball. A playing field of nonferrous material has baseball markings delineated. A pitching mechanism is provided whereby a ferrous metal ball is positioned on the upper surface of the playing field. A first cart, positioned beneath the playing field and out of sight, carries a magnet for the guiding of the ball and is positioned on a first ramp device. A second cart is provided with a relatively heavy weight and positioned on a second ramp, the angle of which is determined by the defensive player of the game. The second cart is attached to the first cart by a string whereby movement of the second cart will affect movement of the first cart. Pitching of the ball is carried out by releasing the second cart and allowing it to roll down the second ramp and pull the first cart along the first ramp.
