Best Sudoku training game ever

I rarely write reviews but this game deserves one. I've tried lots of others in the app store just to get some variety but this is the best one, hands down. The range of difficulty is amazing, I can dial in exactly how hard I want it to be - some patterns are too hard or time consuming for my preference so I can dial it down but still keep it challenging. The tutorials are excellent, the way it compares your time against other players is great, and the puzzles themselves are top-notch. Can't say enough good things about this game. If I had to find an area of improvement it would be the graphics - they're functional but not as nice as some other games out there. But they're not too bad and there are some customization options which are nice. Great game and kudos to the developers!

Best iOS Sudoku - only one missing feature

Probably the best & most complete Sudoku app on iOS. I love the many difficulty levels and the built-in training & hint system as well as the ability to create puzzles from the camera and photo library. The only missing feature is having “central” pencil marks in addition to the standard corner marks. I like using the Snyder (corner) notation to keep track of when there are exactly two possible positions for a number in a square, but I would also like to note where an individual cell has restricted possible solutions. The only app I am aware of that does this is “Classic Sudoku” by Cracking the Cryptic. I wish :)Sudoku+ had this feature - then it would be the only Sudoku app I need!

Good but some flaws

This is a really fantastic sudoku app, and I use it pretty much daily. However, the developer no longer supports it.

One major issue that has cropped up is that it frequently serves puzzles that are one or two grades above what you choose. So choose “mild”, and you’re dealing with an “intricate” puzzle. It’s not consistent, though. And what’s worse is that there’s no indication this has happened until you find yourself stumped on what should be a puzzle that requires no advanced moves.

Beyond that, the “best” time displayed will change pretty constantly while you’re playing a puzzle, so you won’t know what your actual record is until you beat it. And just a complaint, the “lessons” for advanced moves, etc., are incomprehensible. You could have just sat on a keyboard and created clearer instructions than what’s there.
