Abstract: A cube puzzle is provided utilizing a group of 27 smaller cubes which are adapted to be assembled into a larger cube having a 3 by 3 by 3 configuration. The 27 cubes have at least first and second different sets of identifying indicia on each face thereof. The first set of identifying indicia include up to nine different numbers, some of which may be duplicated on different faces of any one cube and which are also oriented differently on different faces. A preferred embodiment of the assembled cube utilizes the numbers one to nine for the first set of indicia. The second set of identifying indicia include up to six different colors which also may be duplicated on different faces of the same cube. The cube puzzle also includes a transparent case having at least one removable face which may be used not only to package the puzzle but also for its assembly.
