About this puzzle

A medium 20x20 grid in the weather theme, Moon 20x20 Nonogram hides a recognisable picture once the logic clicks. About 36% of the grid is shaded — 144 filled cells out of 400 — which makes for a fairly balanced board.

The biggest single run here is 18 cells long — fill that first and the surrounding lines fall into place faster. Budget about 4 minutes for a relaxed solve.

How to solve this nonogram

At this size, work the longest clues first, then use the cells they force to crack the shorter lines around them. With balanced coverage, alternate between filling forced cells and ruling out empties to keep both kinds of clue moving. Turn Challenge mode on for instant feedback on mistakes, or leave it off for a calmer solve.

Which grid sizes can I play the moon nonogram in?

20x20, 30x30. 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?

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.
