Great App

I am a new player of Sudoku and I’m thrilled that I have come upon the Sudoku Kai app! It is not only user friendly in offering five levels of challenge but creative in offering the user an option to choose playing while in the presence of meditative soundtracks. The app is captivating, with a balance of relaxation, intellectual stimulation, and fun! Although a novice currently, I fully anticipate returning to Sudoku Kai time and again, and plan on not being a novice for long!

I Love This App!

Its exactly what the developer says it is: a relaxing game. It’s easy on the eyes with pleasant calming music in the background. It’s the perfect game to play at bedtime or just to wind down. I have found that the levels match my skills and so far the app has been glitch free… Just easy and fun!

Beautiful and simple

I love this Sudoku game because there isn’t obnoxious sounds and visuals that would keep me up at night. Just peaceful music, pretty backgrounds and basic game play.
