About this puzzle

A easy 12x12 grid in the weather theme, Rainbow 12x12 Nonogram hides a recognisable picture once the logic clicks. About 35% of the grid is shaded — 50 filled cells out of 144 — which makes for a fairly balanced board. The picture is left-right symmetric — solve one side and you can mirror the same logic across the centre column.

The biggest single run here is 10 cells long — fill that first and the surrounding lines fall into place faster. Budget about 2 minutes for a relaxed solve.

How to solve this nonogram

On a small grid like this, read every clue against the full line length — many rows resolve in one pass. With balanced coverage, alternate between filling forced cells and ruling out empties to keep both kinds of clue moving. Spot the symmetry early and you can copy solved sections to the mirrored side instead of re-deriving them. Turn Challenge mode on for instant feedback on mistakes, or leave it off for a calmer solve.

FAQ

FAQ

Which grid sizes can I play the rainbow nonogram in?

12x12, 15x15. 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.
