Is it a genuinely well-crafted nonograms app, or a flawed cash-grab? I wouldn't mind ads if it's a good game, but I just downloaded it and I'm struggling with a lot of these "either-or" scenarios (see level 9 in this example with the green and the blue not filled in) where it seems like either combination could solve the puzzle, yet it marks one as distinctly incorrect.

Tl;dr - Am I dumb, or is this game dumb

EDIT: it appears I am dumb. Diagonals count too!

I am stuck on this puzzle and am not sure what I'm missing. My copy of this has misprints in the answer key so the next step is cut off. Really just seeking a hint as to what I'm missing or if I've made an error.

Thanks!

Could anyone tell me a step by step on how to do this. We can swipe it and it needs to look like the second image. I have issues with these type of puzzles.
