Abstract
A puzzle includes a plurality of elements or blocks stacked end to end and connected together for rotation relative to one another around a common axis. The faces of one or more of the blocks include face portions slidable along the surface of the device from block to block generally along the axis of rotation of said blocks. One block includes an 'open' face without a movable face portion so that the face portions can be redistributed around the device by rotating the blocks around their common axis and sliding the face portions from one block to another. The face portions bear indicia indicating a predetermined arrangement so that beginning with a device having its face portions randomly distributed around the device, the device is manipulated to rearrange the face portions into the predetermined order.
