I consistently come back to this app when I need some Zen time. There are a plethora of puzzles available from small (black and white) and quick to huge with lots of colors involved and occasional reasoning required to determine the correct pixel to paint. [ At the high end of the scale, I spent hundreds of hours on and off over months on a Frank Loyd Wright image. ]

This is THE best nonogram puzzle app in the play store. There tens of thousans of puzzles of various sizes and colors. Some of them even have squares that are half one color and half another. It's a totally new level of difficulty. I've found a few VERY challenging puzzles, that I had to clear and restart several times. 10/10 recommend.

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.
