Puzzle IO - Binary Sudoku

This app is great! I would love to see: * dark mode - it’s blinding at night * better hints - the hint system seems to just randomly give you a digit. I want it to explain the logic of how the digit was selected so I can learn new ways to solve the puzzles Thanks!

Two basic things that annoy me to the point of uninstall: 1. pop ups in the middle of the game asking me whether I want to watch a video in exchange for hints I don’t ever want, 2. my iPhone goes to lock screen while I’m thinking about what numbers to place. Not so basic: several times I accidentally cleared a square and forgot what number I had in it. I feel like you could prevent this frustration altogether with some smart ux rather than relying on that undo button which feels like a quick and dirty solution. Just needs a bit more thought. I like binary sudoku, just not in this app.

I don’t like the new option of having only 3 errors and then waiting for a 30 second advertisement, for something I am not remotely interested in, to finish, before I can get on with a game that I wanted to play to fill in a short break. A real time waster and I don’t like playing this as much.

So disappointing, this app is very unstable. It just stops and cannot down load it again

now the app keeps asking me if i want notifications turned on. the options are Yes and Yes. weird, I don’t want notifications at all so a No option would be useful.

Really do enjoy your game. Well done

I love the game, just wish there was an option to for night mode so it reverses to a black background and lighter numbers

What are you guys running in the background. If this app genuinely needs to run that hard you need to find a new solution to the problem. The game itself is fun but after 7 minutes my phone is already the hottest it’s been. I have an iPhone X and have also played it on the 6+. Both times were always running hard when I played it. It really doesn’t need to use that many resources. You wouldn’t change the solution to this problem since you’ve got other apps to worry about so I think I’ll just swap apps.

Loved binary sudoku for a long time. Couldn’t get enough until this app came along. Great to use, levels of puzzles and nice interface.

I'd pay for an ad free version. Annoying videos advertising other games play after every round. Really disappointing. Otherwise would be best game ever.
