I built this, the list started as a tutorial and then grew out of control. Especially when I started experimenting with mixing text and interactive elements. I think nonograms are underrated and relatively unknown, I hope this text changes it a little. I link to my app[1] frequently, it's free right now, I hope this is fine. There's no Android version yet; for anyone who wants to try nonograms on an Android smartphon…
I am unfamiliar with nonograms. I don't understand from the explanation how the grouping hints work. "When there are two or more numbers, this means there will be two or more groups of filled cells." Is the "group number" the size of the first group? That seems to fit the tutorial example where (1, 2) = (., x, ., .) and (2, 1) = (., ., x, .). Thanks for making this - I've stumbled across these puzzles but never took…
Each number specifies the size of the corresponding group. E.g. numbers “5 4 7” would mean: “three groups of filled cells, first group will consist of 5 cells, second will consist of 4 cells, third group will consist of 7 cells”.
Have fun and I’m happy to hear that this is useful!
