About this puzzle

Worm 50x50 Nonogram is a hard 50x50 picture nonogram from the animal collection. Coverage sits near 39% (986 of 2500 cells), giving you a fairly balanced picture to uncover.

The biggest single run here is 43 cells long — fill that first and the surrounding lines fall into place faster. Most solvers clear a board like this in around 38 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. Turn Challenge mode on for instant feedback on mistakes, or leave it off for a calmer solve.
