Adjacent Triple
Easy
Used by Smart Hint
Three equal numbers in a row: only one may stay, and rejected cells can't touch — so the two ends are rejected and the middle is kept.

- Where the conclusion lands
How it works
- Three 2s sit side by side in the top row. At most one of them may be kept — so at least two must be rejected.
- Rejected cells can never touch, and the only way to reject two of three consecutive cells without touching is the two ends.
- Reject both end 2s and keep the middle one.
