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.

FAQ

FAQ

Which grid sizes can I play the lightning nonogram in?

50x50, 60x60. Smaller grids show a simpler outline and take a few minutes; larger ones add detail and turn into a longer, more careful solve.

Does this puzzle save my progress?

Yes. Your moves and timer are saved in the browser after every action, so you can close the tab and come back later without losing anything. Each grid size keeps its own progress.

How do I check for mistakes?

Tap Check any time for a manual review, or turn on Challenge mode for immediate feedback as you play.

What do the X marks do?

X marks flag cells you've proved are empty. They don't affect the solution, but they make bigger grids much easier to track.
