About this puzzle

Otter 30x30 Nonogram sits in the fish theme as a hard 30x30 picross board. 270 of its 900 squares are filled, so it reads as a fairly balanced grid at roughly 30% coverage.

The biggest single run here is 21 cells long — fill that first and the surrounding lines fall into place faster. Expect to spend roughly 14 minutes from a blank grid to the finished picture.

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. Turn Challenge mode on for instant feedback on mistakes, or leave it off for a calmer solve.
