Soma Cube

The Soma Cube is a three-dimensional puzzle consisting of seven irregularly shaped pieces made from unit cubes. The challenge is to assemble these pieces to form a solid 3x3x3 cube or various other shapes. Each piece can be rotated and flipped, making the puzzle a test of spatial reasoning and problem-solving skills. Designed by Danish mathematician Piet Hein in 1936, it combines geometric curiosity with creative assembly and is popular among puzzle enthusiasts and educators for developing visualization and thinking skills.
