Hints: where to start on level 25
These clues allow just one set of digits, so they're the best openings:
- 16 in 2 (down) can only be 7 + 9.
- 34 in 5 (down) can only be 4 + 6 + 7 + 8 + 9.
- 3 in 2 (down) can only be 1 + 2.
- 17 in 2 (across) can only be 8 + 9.
Where an across and a down run with known digit sets cross, the shared digit is often the only one both allow.
