About this puzzle

Heart 10x10 Nonogram is an easy 10x10 picture nonogram from the heart collection. Coverage sits near 48% (48 of 100 cells), giving you a dense, heavily filled picture to uncover. 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 8 cells, so anchoring that block early gives you a reliable foothold. Most solvers clear a board like this in around 2 minutes.

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 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.

10x10, 12x12, 15x15, 20x20, 30x30, 40x40. 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.
