A manipulative puzzle game consisting of a rectangular parallelepiped box having a transparent front wall. A plurality of identical cubes are disposed within the box. At least one plane face of each cube bears a visually distinguishing feature. The objective of the game is to arrange the cubes by manipulating the box, so that the visually distinguishing features of the cubes are in a selected order. The number of cubes is one less than the capacity of the box for such cubes. The width of the side walls of the box is slightly greater than the diagonal of a face of a cube, and less than twice the edge length of a cube, so that the stacks or layers of cubes are of a thickness of the edge dimension of a cube, i.e., one cube thick, and so that careful manipulation of the box by horizontal twisting or by tapping the box causes the rotation of at least one of the cubes about a central vertical axis. The height of the box is slightly greater then the total height of the highest stack of cubes in the box to permit at least one upper cube to roll over about a lower horizonal edge upon careful tilting of the box.
