If you want to try solving a nonogram on an iOS device, I made a show hn about that yesterday: https://news.ycombinator.com/item?id=44766657

Picross (which is based on nonograms) is my favorite puzzle game. Side note for anyone who thinks we're close to AGI, try giving an LLM even a simple nonogram to solve.
