About this puzzle

A easy 10x10 grid in the heart theme, Heartbeat 10x10 Nonogram hides a recognisable picture once the logic clicks. About 41% of the grid is shaded — 41 filled cells out of 100 — which makes for a fairly balanced board.

Its longest clue runs to 8 cells, so anchoring that block early gives you a reliable foothold. 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. Use Check whenever you want to confirm progress, and switch on Challenge mode if you prefer catching errors as they happen.
