Anti-Knight
Cells a chess knight's move apart can never hold the same digit.
Tips
- ◆From any digit, the eight knight-jump cells are ruled out for that digit.
- ◆The rule reaches across boxes, so it links cells classic rules never touch.
- ◆Nothing is drawn on the grid — check the knight cells every time you place.
