About this puzzle
Heart 40x40 Nonogram sits in the heart theme as a hard 40x40 picross board. 764 of its 1600 squares are filled, so it reads as a dense, heavily filled grid at roughly 48% coverage. 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 34 cells long — fill that first and the surrounding lines fall into place faster. Expect to spend roughly 25 minutes from a blank grid to the finished picture.
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. 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. Turn Challenge mode on for instant feedback on mistakes, or leave it off for a calmer solve.
