Anti-Knight Invisible Arrows Sudoku
(Published on 24. September 2020, 20:03 by stephane.bura)

I'm done with arrow puzzles. Normal Sudoku rules apply. Two cells a knight's move away from one another can't contain the same digit. From each gray cell you can draw at least one straight 2-cell long orthogonal arrow. The digit at the origin of the arrow is the sum of the two digits on the arrow. All the possible gray cells are given. Enjoy! |
