A puzzle device includes a plurality of cubes. Each cube has visual matter on a plurality of its faces. The cubes are arrangeable at least twice in a pre-determined way into a rectangular parallelepiped with the cubes in adjacency and with their exposed faces forming at least five of the six sides of the parallelepiped. Each cube is unique, with respect to its visual matter, with respect to all other cubes, and the visual format on the cubes is such that in each pre-determined arrangement, the exposed faces of the cubes together form a pre-determined visual format. For example, a set of cubes is arrangeable in three different ways into a parallelepiped thus providing a total of fifteen different visual formats, one on each of the four sides and top of the parallelepiped formed by arrangement of the cubes.
