I have played Sudoku Master before on another device and I loved it so when I got a tablet for Christmas knew I wanted it on my new device. Simple to play and a great brain exercise. Relaxing too and with this China virus a great time waster! I really like it!! I have tried several other Sudoku games and controls are too complicated. There are several degrees of difficulty too!
The best sudoku so far. I love how simple the app is. I can't tell you how much I recommend this app, it is so calm.
Using Sudoku to for about an 26 Years. I like This Brainy Game. I. wish to Rate it as 5 + Stars .
