No sound

It used to be a great Sudoku, but in recent months the sound has been almost constantly absent - it appears only at the beginning of the game for 30-40 seconds and then turns off. That's why I'm looking for a better sudoku now

Games fine

Ads make it unusable

Restore purchase

Why after four months do I have to press the restore purchase button and the button doesn’t work ? Frustrating when there is a lot of other sudoku games in the apps store and it happens that I bought the buggy one.

Privacy concerns

I literally paid for the ad free version and they turned right around and updated their privacy policy which states they reserve the right to sell your browser habits. Explain to me why a sudoku app needs to monitor and sell my browser history???

Garbage app due to ads

Trash click bait app. Ads that don't end after every game. Fing waste of time. Stay away.
