- Play offline. I see no reason you couldn’t play in airplane mode.
- Endless. No way you solve all levels in your lifetime.
- No ads. Nobody likes ads.
- No in-app purchases. Big one, isn't it?
- No account creation. Why would you need to create an account to play a game? Who does that?
- No tracking. The game imports 0 third party libraries so 0 is tracking you. I don’t need to know how, when and where you play.
- Synchronized progress. Pickup the game you started on any device logged into your iCloud.
- Available on iPad, iPhone, Apple TV and Mac.
Anything else? That's all! It's classic Sudoku but with Emojis instead of numbers.
