SteamAbout Soma Cube
Test your spatial reasoning with Soma Cube, a classic 3D puzzle brought to life as a digital game.
The puzzle uses seven unique pieces made from small cubes. Your goal is to rotate, move, and fit them together to build a complete 3x3 cube or one of many other 3D shapes.
The rules are simple. Finding the solution is not.
The game currently includes 12 handcrafted puzzles, ranging from the original cube to more unusual constructions.
Features
Soma Cube is based on the puzzle invented by Piet Hein in 1933 and is also known as Block by Block. It is a compact but demanding challenge for players who enjoy logic puzzles, spatial thinking, and solving problems at their own pace.
