Magic Squares

In this game, a starting number and a square of X * X squares are first selected (3x3, 5x5, 7x7, 9x9, 11x11). Then the fields are filled in with consecutive numbers from the starting number and up until all fields are filled in. All rows, columns and diagonals must give the same sum. It can be played without rules or after the rules specified in the game. If you play according to rules and a game board (3x3) is selected with the starting number 1, the sum of rows, columns and diagonals must give 15. A field is activated by a light tap with your finger.
