Each tetracube consists of four cubes. There are eight tetracubes in total: five are planar, and three are genuinely three-dimensional. Tetracubes belong to the family of polycubes.

Shapes constructed from all eight tetracubes consist of 8 × 4 = 32 unit cubes. One example is a 2×4×4 cuboid. In addition to this, many other shapes exist.

Each of the 8 puzzle pieces can be assembled in an enlarged form from all 8 tetracubes. The resulting shape has twice the edge length and therefore 8 times the volume of the original game piece.

The 3D-print templates consist of 8 Tetracubes and a box.

The Online Tetrakubus Solver runs directly in the browser – no installation and no download required.

Figures can be assembled easily with a few mouse clicks and then solved. The found solutions are output without symmetry reduction – solutions that differ only by rotation or mirroring are counted as separate solutions.

The solution program for the Tetracube puzzle is part of a collection of programs available for download on Itch.io. It is for Windows only.
