About this puzzle

A hard 40x40 grid in the food theme, Cookie 40x40 Nonogram hides a recognisable picture once the logic clicks. About 50% of the grid is shaded — 803 filled cells out of 1600 — which makes for a dense, heavily filled board.

The biggest single run here is 35 cells long — fill that first and the surrounding lines fall into place faster. 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 so many cells filled, look for clues that nearly span their line; those leave little room and fill quickly. Turn Challenge mode on for instant feedback on mistakes, or leave it off for a calmer solve.
