A puzzle device is provided which comprises a series of channels, formed around the surface of a spherical core by a series of transparent hollow arcuate members, having two diametrically opposed points of intersection forming chambers. A plurality of spherical puzzle members is disposed in surface to surface contact within said channels. With the puzzle disposed with the chambers located on a vertical axis the lowermost puzzle pieces in each of the channels are in contact with each other and one puzzle piece is located in the uppermost chamber and is supported herein by contact with the uppermost of the puzzle pieces in at least one of the channels. Rotation of the puzzle through 180 DEG in the plane of one of said channels causes the latter puzzle piece to be directed into that channel and, simultaneously, a puzzle piece originally located in the lowermost part of the same channel is caused to enter the chamber which has become the uppermost after the rotation has been completed. The puzzle pieces are present as groups the members of each group having visually identifiable characteristics. An object of the puzzle is to rearrange the puzzle pieces by successive 180 DEG rotations so as to achieve any predetermined arrangement of the visually distinguishable groups in the various channels.
