About this puzzle

Cat Crest 20x20 Nonogram is a medium 20x20 picture nonogram from the cat collection. Coverage sits near 45% (180 of 400 cells), giving you a fairly balanced picture to uncover. 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 16 cells long — fill that first and the surrounding lines fall into place faster. Most solvers clear a board like this in around 4 minutes.

How to solve this nonogram

At this size, work the longest clues first, then use the cells they force to crack the shorter lines around them. 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.
