Cube Soma-7 is a digital version of the classic 3D puzzle Soma Cube, invented by Danish mathematician and poet Piet Hein. The program offers more than 300 unique challenges and lets you solve built-in puzzles or create your own.
It’s ideal as brain exercise and perfect for passing the time while challenging your spatial awareness and logic.
