About this puzzle

Hippo 15x15 Nonogram is an easy 15x15 picture nonogram from the animal collection. Coverage sits near 38% (85 of 225 cells), giving you a fairly balanced picture to uncover.

The biggest single run here is 13 cells long — fill that first and the surrounding lines fall into place faster. Most solvers clear a board like this in around 2 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.

FAQ

FAQ

Which grid sizes can I play the hippo nonogram in?

15x15, 20x20. Smaller grids show a simpler outline and take a few minutes; larger ones add detail and turn into a longer, more careful solve.

Does this puzzle save my progress?

Yes. Your moves and timer are saved in the browser after every action, so you can close the tab and come back later without losing anything. Each grid size keeps its own progress.

How do I check for mistakes?

Tap Check any time for a manual review, or turn on Challenge mode for immediate feedback as you play.

What do the X marks do?

X marks flag cells you've proved are empty. They don't affect the solution, but they make bigger grids much easier to track.
