Soma Cube invented by Piet Hein in 1936. This set of seven Soma pieces could be formed into a 3x3x3 cube. This puzzle can be used to help develop skills in visualizing spatial relationships. (Picture 1 ) It can be proven that there are exactly 240 different ways to put the Soma pieces together to form the 3x3x3 Soma Cube. In addition, many figures such as animals, furniture... can be made from the seven Soma pieces. (Picture 2) If you use your imagination and creativity, you can get more figures and more fun. (Picture 3) If you have more Soma sets, you can try more complicated constructions.
