Great puzzle game that gets you thinking logically, but it has a couple of minor inconveniences. While the puzzles are organized into their own folders, inside of the folder you can have a couple different types of puzzles with triangle and color picross mixed in with the others and no way to distinguish from the menu. Also ui is a bit difficult to manage for larger than 15x15 puzzles on most phones.

This game is similar to a game I fell in love with a few years ago called CrossMe. This game is so much better with it's implementation of hints and the sheer number of puzzles available. I play around 1-2 hours a day and no end in sight. The only problems I have are that I my ranking doesn't display properly and I cannot login to save my progress.

This has been my #1 favorite nonogram game for around 5 years now. It's the only one I've kept & will probably ever keep. It's great for all skill levels, which I especially love bc I really enjoy a challenge. Some of the advanced ones will totally wrack your brain. But then if I just need something simple to keep me occupied I can do an easy puzzle in 1-2 minutes or less. Very relaxing and mentally stimulating at the same time. I play to stay sharp and ease my anxiety. Can't recommend enough!
