Logic Masters Deutschland e.V.

Magic Arrow

Rules:

Place the the digits 0 to 8 exactly once each in every row, column and 3x3 box. Each box is identical to exactly two other boxes i.e. on same positions are same digits on those boxes (which boxes are identical must be determined by the solver). Digits along an arrow must sum to the digit in that arrow's circle. The middle box on the grid is a magic square i.e. the sum on each row, column and diagonal on that box is the same.
