Best sudoku app out there

The options alone make this app the best. You can go from easiest to hardest in all the different settings offered. Are you new to sudoku, this is the best app to start, not only can you adjust the settings to your perfect setup, the game also teaches you how to play with telling you how and why a certain grouping works or doesn’t.

I have had this app for years and it only gets better. I’ve lost a lot of older apps to the developers not putting time into upgrading it or even keeping it up to date with updates. The developers of this app make sure that doesn’t happen. They are amazing and every upgrade to the app I’ve seen I’ve absolutely loved. Thanks for such a great app.

This has all the options, and more!

This is the absolute best Sudoku app - and I've tried a bunch of them trying to get one I like! It has options for EVERYTHING, including all the different ways to do pencil marks! You can set "pick a number, then a cell," or vice versa! Best of all, the hints can do everything from a simple "is board solvable (do I have anything wrong)" to "undo until solvable" (!) to "hint" - which will then lead you through AND TRAIN YOU on advanced solving techniques! Absolutely amazing app! The free version gives you one of each game each day, which is a good hour+ of play time, but it'll be worth paying for the full version just because this is SO GOOD!

I love this game so far

I am just a beginner and just starting to use this app, but tried several others before I found this one. I don’t want to compete I just want a simple mind game. So far the game allows me to take as long as I want and doesn't rag at me with advertisements. The timer doesn’t seem to be optional, but I don’t mind that as I long as I have the option not to play with others. The variety of game levels seems wide. The other thing I like is that I can choose a harder game one day and a relaxing easy one the next day. The other apps I tried were in my face competitive. So I am very happy with this app.
