About this puzzle

A hard 50x50 grid in the weather theme, Lightning 50x50 Nonogram hides a recognisable picture once the logic clicks. About 26% of the grid is shaded — 648 filled cells out of 2500 — which makes for an open, sparsely filled board.

Its longest clue runs to 36 cells, so anchoring that block early gives you a reliable foothold. Budget about 38 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. Because the picture is sparse, X marks for empty cells do most of the heavy lifting — flag them generously. Use Check whenever you want to confirm progress, and switch on Challenge mode if you prefer catching errors as they happen.
