What is a nonogram?
A picture logic puzzle, also called picture cross, griddler or paint by numbers. The numbers beside each row and column give the lengths of the runs of filled squares in that line. Fill the right squares and a picture appears.
Is Hoopcross free?
Yes. It's free to download and play, supported by ads. There's nothing to buy.
How many ads will I see?
None during a puzzle and no banners. A short ad can appear between puzzles, at most every third break and never within a couple of minutes of the last one. Videos for coins only play when you tap them.
Do I ever have to guess?
No. Every puzzle is checked by a solver that only uses one row or column at a time, so there is always a next square you can work out.
Does it work offline?
Yes. No Wi-Fi or mobile data needed to play.
