5 stars: Best version of sudoko among free games out there. I've come across. Excellent layout and good graded levels that get more difficult as you play them. *Pencil* numbers nice and small but clear. Background easy on the eyes and unobtrusive. If you want them there are hints and if you're stuck or you've goofed up you always have the option of starting over which is satisfying too.
3 stars: Great game option... however, those ads need to be cut down to 5 seconds max. We shouldn't have to wait for those ads to complete. That just turns people off. You can grab someone's interest in the first few seconds of the ad and leave them wanting more. When it's drawn out, then I loose interest.
5 stars: I have been using this app for years and find it very easy to understand and manipulate. I play one or two games each day, just to increase my mental quickness and memory. It is easy to correct mistakes and to restart a game, if need be.
5 stars: Sudoku puzzles with built in feature that lets you put notes in cells to help you remember you placements. It is not stopped to force you to watch ads. This is why it is, literally, the only game on my phone!
3 stars: The app is decent but I would like the ability to turn off ALL sounds. I \
5 stars: I would give this more stars if I could! It does what it says it does - provides a game that is easy to learn, is always stable, and let's you train your brain with the best the playing experience.
5 stars: Thrilling exp...
