Classically awesome

This possibly could be one of the oldest apps on my phone because it is great and I’ve never needed anything else from a Sudoku game. All the features you could need are there and work great and continue to work great over the years. I will not be looking for another Sudoku app as long as this is around.

Simply the best app. I’ve tried many.

I’ve been playing it for years. It has an infinite amount of levels for any skill, and a daily puzzle.

My only wish is to increase the contrast between the color of the numbers that are all placed and those which aren’t yet.

Good app

I really enjoy this version of sudoku, the only problem I have is the invasive adds that flash and spin and that literally keep you from concentrating, there outright irritating. Quite a few times I just end up shutting it off completely frustrated!
