About this puzzle

A hard 40x40 grid in the animal theme, Cow 40x40 Nonogram hides a recognisable picture once the logic clicks. About 32% of the grid is shaded — 509 filled cells out of 1600 — which makes for a fairly balanced board.

Its longest clue runs to 33 cells, so anchoring that block early gives you a reliable foothold. Budget about 25 minutes for a relaxed solve.

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.
