Abstract
An amusement device has a housing with a chamber in which a game board is disposed. A player endeavors to guide a rolling ball on the board by manipulating a control lever to tilt the board in any selected direction. The board is supported by a tiltable shaft which is below the center of the board. A rigid link extends between the shaft and control lever and is connected to each by pivot couplings which constrain the shaft and board to tilt in synchronism with the lever. Compression springs in coaxial relationship with the shaft and control lever act to bias the board towards a horizontal orientation and the shaft and lever supports prevent rotational motion of such components about their own longitudinal axes. In a preferred embodiment, the board has openings through which the ball may drop and ball retrieval components detect the particular region of the board at which the ball was dropped and return the ball to the board. The construction precisely positions the board in response to control lever movements and enables simple interchanging of the board with other boards having different surface features.
