About this puzzle

Hippo 20x20 Nonogram is a medium 20x20 picture nonogram from the animal collection. Coverage sits near 37% (147 of 400 cells), giving you a fairly balanced picture to uncover.

The biggest single run here is 17 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. Turn Challenge mode on for instant feedback on mistakes, or leave it off for a calmer solve.
