Board game apparatus

An impoved game apparatus of the type employing sound producing pieces. A sonorous board is employed and the pieces are so constructed that certain ones will produce a concussion of the board by means of a hidden impactor. The concussion causes the board to vibrate, thus producing the sound. The pieces are of such form and appearance that those which will produce sound are not visually identifiable as such. In a first embodiment all the pieces have the same outward appearance but are of different colors on top and bottom faces. In a second embodiment the pieces display the same color on top and bottom but are constructed so as to produce sound in only one orientation, which is not visually identifiable. In a third embodiment each piece is colored on one face only and is supported upon the board by a compliant body. The impactor is concealed within the compliant body on certain pieces only.
