We offer 4 difficulty levels. If you still get bored, please send us an email!

Not just back and forward!
Do I need a 6 or a 4 here? Why no try both? Any situation you encountered can be easily accessed in our History

Gesture input:
Tired of buttons? Just write the number on the screen with your finger!

Usefull assistances:
Need a hint? OK, we give you one. But you can not only check if you've made any mistakes so far. You can even let us take you back to the last correct status. Among other stuff.

We don't need internet.
SudoQ doesn't need to connect to any server before or while you play.
We neither need to download the sudokus nor do we need to send data anywhere.

Cow
We have a cow. Take that other sudoku-apps!

100% open source
Suspicious about what our app really does? Check the source!

SudoQ doesn't crawl for your data
We don't want it. Really. Check the code. Actually:

You don't need to give permission to:
-access any network, send or receive data
-look through your contacts
-read your phone state
-kidnap your grandma
-Whatsoever

-> we want you to enjoy sudoku, nothing more.

If you have trouble with the app please open an issue on github(or fix it on your own) or send us an email.
