Partner Check
Only two cells of this run are empty, so they split the remaining sum between them — a digit whose partner (remaining sum minus it) can't go in the other cell is impossible.
How it works
- 1Only two cells of this across run are empty, so they split its 11 between them — fix one and the other is forced.
- 2The right-hand cell shares a 16-in-two down run, and 16 over two cells is only 7 + 9.
- 3So 2 pairs with the 9 and 4 pairs with the 7, both fine — but 3 would need an 8 beside it and 5 would need a 6, and neither digit is available there.
- 4Strike 3 and 5 from the left cell.
- Cells that establish the pattern
- Where the conclusion lands
- Digit ruled out
