The Soma Cube was invented by the Danish poet Piet Hein in 1936 and became the rage of the early 1970s. It remains as one of the most popular and intriguing puzzles in history.
"It is a beautiful freak of nature that the seven simplest irregular combinations of cubes can form a cube again. Variety growing out of unity returns to unity. It is the world's smallest philosophical system." -Piet Hein, discoverer of the Soma Cube
Soma pieces are irregular shapes formed by joining identical cubes at their faces. The seven Soma pieces can be arranged in 240 ways to build the famous 3x3x3 cube as well as a whole range of other structures. This modern version of the classic puzzle is called Block by Block.
It is identical to the traditional Soma Cube and includes 60 cards with a whole panoply of Soma shapes to create such as the Lobster, Tyrannosaurus, Pyramid, Sofa, Castle and Shower Block.
