Ratings and Reviews



I love sudoku and when I found out there were different versions I searched for an app that had em this one does!! Love it I'm addicted just wish they had more different ones like Blackout sudoku and jigsaw sudoku

Almost perfect


This app is one of the only ways to play killer sudoku with sums. My only complaint is that I can't control the sound without it changing the volume if the ringer. Most apps have the sound separate from phone volume, I would recommend changing that.

Best sudoku app!
