Polycube Puzzle, SOMA Cube

<< >>
The SOMA cube is a three-dimensional arrangement puzzle devised in 1936 by the Danish poet and puzzler Peter Hein (1905-1996) while he was a student listening to a lecture on quantum mechanics by Werner Heisenberg. The seven pieces represent all the ways three or four cubes can be arranged, other than in a straight line. In addition to forming a cube, the pieces can form in a wide array of other surfaces. According to Slocum and Bosterman, the name SOMA is taken from a drug envisioned in Aldous Huxley’s book Brave New World. The drug SOMA induced a dreamlike trance.
This example of the puzzle is made from light blue plastic. It closely resembles one sold by Parker Brothers from the late 1960s.
