[origin: ES290776U] A puzzle cube consists of a plurality of components which in spatially interengaging manner fill out the volume of the cube and are one detachable from the other. The volume of the cube is subdivided into sixty-four equally large small cubes, wherein thirteen geometrically different components (1 to 13) are provided, each of which consists of several small cubes placed with their side surfaces flush one against the other and connected firmly one with the other. At least two small cubes are placed one against the other in each of three mutually perpendicular spatial directions in each of the components.
