I've been playing with a nonogram app for the last several days. The best thing about this one is that it has an editor where you can make your own puzzles, which is what I've been doing. There's something interesting about making nonograms that's more satisfying for me than just making pixel art (for which I lack the patience to make it really good). First I make the black and white shape and try to make it as readable as possible, while still complying with the nonogram solveability rules (the editor checks this for me, which is very handy). Then I draw the colour overlay that the app displays after you've solved the puzzle. These take like 10 minutes to make and 5 minutes to solve. I also made a few smaller zodiac themed puzzles, which are even simpler (but there's not much detail I can cram into 10x10 pixels).
The base game, which includes the community content, such as the puzzles I made, is free to play. The only thing it doesn't do is give me an easy way to export the puzzles in a printer friendly format, so if you want to solve these for yourself, you'll have to make do with the screenshots I made, or find them in the community art section ingame. They're all currently fairly high up in the "newest", and my username is "baku".
