  • Patent number: 5201524
    Abstract: A marble game including a stationary top board having a plurality of spaced apart game holes to define a game path. A rotatable bottom board includes a plurality of randomly spaced apart sink holes for aligning with the game holes. A marble positioned in a game hole aligned with a sink hole falls through and on to a ramp surface which guides the marble angularly downward to a retrieval location. A slot opening in the top board registers with a shift aperture in the bottom board. Applying an external force inside a registered shift aperture in a clockwise or counter clockwise direction rotates the bottom board until another shift aperture registers with the slot.
