The puzzle Verschlungene Quadrat or "Entanlged Squares" consists of 3 connected squares. The fields must be filled in such a way that each of the 3 squares is a magic square.
A square is called magic if the sum of the numbers in each row, column and 2 diagonals is the same. It is a very difficult puzzle.
