The numbers are placed on each square so that the total of columns, horizontal rows, and diagonal columns is all equal. The total of this number is called the magical invariant. In the medieval Europe, it was believed that the magic team had the power to transcend nature, so the magic team was also used as a amulet charm that protects himself from curse eyes, pests, and other illnesses. 。 (Reference document: "Shape Mysterious 1" Bruno Munari)
