Ratings and reviews

I love playing binary games and this app is awesome. I really like that the puzzles go up to harder sizes and are actually challenging 😁 I've played too many other apps that only go up to 8×8 and penalize you for mistakes. This app doesn't do that! Also, the ads are minimal which is nice, you're not being bombarded every 2 seconds with one ad then another 👍

Good binary puzzles are hard to come by and this one was pretty awesome. There are great options to choose from. You can play 6x6 thru 14x14 squares. Choose difficulty between 1 and 4. My only recommendation for the developers is to create a button to click to place 1s or 0s, rather than tapping once for 0 and twice for . it's more time consuming and leaves room for more mistakes

I paid for No Ads. The charge came out of my account, the app updated to reflect the purchase for a couple hours and then Ads started back up. There's no contact method in the app. I had to go through socials and the message from had an option to attach screenshots that also didn't work. Very disappointed.
