About this puzzle

A hard 40x40 grid in the emoji theme, Grinning Face 40x40 Nonogram hides a recognisable picture once the logic clicks. About 52% of the grid is shaded — 824 filled cells out of 1600 — which makes for a dense, heavily filled board. The picture is left-right symmetric — solve one side and you can mirror the same logic across the centre column.

Its longest clue runs to 36 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 so many cells filled, look for clues that nearly span their line; those leave little room and fill quickly. 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.
