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.

FAQ

FAQ

Which grid sizes can I play the otter nonogram in?

30x30, 40x40. Smaller grids show a simpler outline and take a few minutes; larger ones add detail and turn into a longer, more careful solve.

Does this puzzle save my progress?

Yes. Your moves and timer are saved in the browser after every action, so you can close the tab and come back later without losing anything. Each grid size keeps its own progress.

How do I check for mistakes?

Tap Check any time for a manual review, or turn on Challenge mode for immediate feedback as you play.

What do the X marks do?

X marks flag cells you've proved are empty. They don't affect the solution, but they make bigger grids much easier to track.
