CASE 4376

Who's shooting at the diagonal

  • Diagonals
  • Arrows

The brief

Normal irregular 7x7 Sudoku rules apply, i.e. each row, column and region has to contain the digits from 1 to 7. Digits on an arrow sum to the digit in the circle from which the arrow emerges. On the positive main diagonal digits do not repeat.
