About this puzzle

Fish 40x40 Nonogram sits in the fish theme as a hard 40x40 picross board. 526 of its 1600 squares are filled, so it reads as a fairly balanced grid at roughly 33% coverage. The picture is top-bottom symmetric, so the lower half echoes the rows you work out up top.

Its longest clue runs to 33 cells, so anchoring that block early gives you a reliable foothold. Expect to spend roughly 25 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. Spot the symmetry early and you can copy solved sections to the mirrored side instead of re-deriving them. Use Check whenever you want to confirm progress, and switch on Challenge mode if you prefer catching errors as they happen.
