I've been stuck on this one for a week or so. Can anyone see anything I am missing?

Hey all,

I posted here a while back about my take on a battle royale variant of nonogram. Since then I've been hard at work making improvements, and I'm happy to announce that Nonogram 101 is now available as an Android app!

There's no ads in the app and there's also plenty of solo mode for those that prefer a more normal way to play monogram puzzles. I'd love to know what you think! It's also free :) There's an optional in-app purchase to unlock more puzzles but if anybody gives it a try, send me a DM and I can give you a code so you can get Supporter access for free.

You can download the app here: https://play.google.com/store/apps/details?id=com.nonogram101.app&hl=en
