Legend has it that one day the overflow of a river occurred; the people, fearful, tried to make an offering to the god of the river Lo to calm their anger. However, each time they did it, a turtle appeared around the offering without accepting it, until a boy realized the peculiar marks of the turtle's shell, so that they could include in their offering the requested amount: 15, God being satisfied and returning the waters to their channel.
The inscriptions of the shell of torture were nothing more than a 3 x 3 grid in which the numbers 1 through 9 were arranged so that the sum of all rows, columns and diagonals gave the same value: 15.
Are you able to place the numbers from 1 to 9 on this 3 x 3 square to make it magical?
