Teaches you as you go

TL;DR: Best Sudoku app, the only one you’ll every need/want because reasons (below). I have a couple silly suggestions (again, below).

I have had this Sudoku app for years. I love it! I have tried several other sudoku apps over the years and I haven’t found any that offer all the functionality this one has to offer. I don’t understand why anyone would ever want anything else.

This app makes it very easy for you to switch between making notes and filling in answers; it can highlight and erase numbers and notes, or not; it automatically gives you a difficulty progression to follow everyday, if you choose; you can work square by square (usually the only choice offered in other apps) or number by number (my preferred method); and if you need to use a hint, it will walk you thru a tutorial on how to find an answer to fill in, teaching you how to become a better sudoku master along the way!

My only suggestions would be to maybe add fluff, like levels or experience points to track how much work people have done, maybe personal high scores for difficulty levels and not just daily global high scores, and other choices along those lines that will make it seem more like some of those other apps that lure people away from this app, the best sudoku in the App Store (that I a m aware of).

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!
