description Soma Cube Overview
The Soma Cube is a three-dimensional assembly puzzle invented by Danish mathematician and poet Piet Hein in 1933. The puzzle consists of seven distinct pieces, each formed by gluing together three or four unit cubes (polycubes) at their faces. The six tetracube pieces and one tricube piece must be assembled into a 3×3×3 cube. There are 240 essentially different solutions, excluding rotations and reflections.
The puzzle has been marketed commercially since the 1960s and has inspired numerous combinatorial and recreational mathematics studies.
help Soma Cube FAQ
Who invented the Soma Cube puzzle?
The Soma Cube is a three-dimensional assembly puzzle invented by the Danish mathematician and poet Piet Hein in 1933. He reportedly conceived the idea during a lecture on quantum physics.
How many pieces make up the Soma Cube?
The puzzle consists of exactly seven distinct pieces, each formed by gluing together three or four unit cubes at their faces. These pieces include six different tetracubes and one specific tricube.
What is the goal of the Soma Cube puzzle?
The objective is to assemble the seven non-identical polycube pieces into one larger 3x3x3 cube. There are 240 distinct ways to solve it, but finding one requires strong spatial reasoning.
Can you build other shapes with the Soma Cube pieces?
Yes, beyond the standard cube, the seven pieces can be combined to form thousands of other interesting geometric shapes and figures. Players often challenge themselves to create animals, buildings, and abstract designs.
