About this puzzle

Dog Bone 40x40 Nonogram is a medium 40x40 picture nonogram from the dog collection. Coverage sits near 32% (504 of 1600 cells), giving you a fairly balanced picture to uncover. The image is symmetric both left-to-right and top-to-bottom, so progress on one quarter mirrors across the whole board.

The biggest single run here is 36 cells long — fill that first and the surrounding lines fall into place faster. Most solvers clear a board like this in around 17 minutes.

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 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.
