About this puzzle

Otter 30x30 Nonogram is a hard 30x30 picture nonogram from the animal collection. Coverage sits near 30% (270 of 900 cells), giving you a fairly balanced picture to uncover.

Its longest clue runs to 21 cells, so anchoring that block early gives you a reliable foothold. Most solvers clear a board like this in around 14 minutes.

How to solve this nonogram

On a large board, divide it into zones: lock in the longest clues, mark proven-empty cells with X, and only then chase the tight lines. With balanced coverage, alternate between filling forced cells and ruling out empties to keep both kinds of clue moving. Use Check whenever you want to confirm progress, and switch on Challenge mode if you prefer catching errors as they happen.
