A cube packing comprises two truncated pyramids configured for a packing mode and a stand mode. In the packing mode, each pyramid touches three faces. In the stand mode, a first pyramid lays on a substantially horizontal surface, a second pyramid rests on the first pyramid and a large cube resides in the second pyramid while having a vertex pointing upwards. The large cube consists of eight small cubes, which in turn consist of a first group of eight pieces and a second group of 16 pieces. Each small cube includes one piece of the first group and two pieces of the second group. The eight pieces of the first group include at least three pieces different from each other at least by color, and may include at least three pieces different from each other at least by shape. In addition, the 16 pieces of the second group include at least three pieces different from each other at least by shape, and may include at least three pieces different from each other at least by color. Each small cube consists 3×3×3 mini-cubes by volume.
