Arrow

Arrow is a variant of Sudoku which adds arrows to the grid. Arrow consists of Sum cell marked with circle and Arrow line cells which have to sum to value in the circle cell. Values on the arrow line can repeat as long as that does not break any other rule.

German whisper image

In the image above we can see:

  • Green cell must be 5, because arrows with single cell arrow have same sum cell and arrow cell
  • Yellow cell must be at least 6 because all 3 cells on the arrow line are in same row, which means they cannot repeat. Minimal value for three cells is 1+2+3 which is 6.
  • Purple cell must be 9 because we have two cells in box 1 with minimal value of 3 and three cells in box 2 with minimal value of 6.
