Separated by One
Easy
Used by Smart Hint
Two clues with exactly one empty cell between them in a row or column — that cell is sea.
- Sea
- Cells that establish the pattern
- Where the conclusion lands
How it works
- Two clues sit in the same row with exactly one empty cell between them.
- That middle cell touches both clues — joining either island would connect them, which isn't allowed. It's sea.
