Literally the best sudoku app on any platform
Perfect. The interface is clean and easy to use. You are able to enter digits and pencil marks with a single swipe, as opposed to the keyboard method used by most other apps, which makes it far quicker to complete puzzles, and it makes the app easier to use with a single hand/thumb. There is a great variety of puzzles, as well as stat tracking, and the ability to customise your experience with features like automatic pencil mark removal, error checking, etc.
However the biggest selling point of this app is the hint system. This app, unlike any other I have used, uses the hint system to not only help you with your current puzzle, but to teach you to get better at sudoku. There are so many techniques that I would never have known about if it weren't for the hint system in this app. It doesn't just give you the answer, it points out where you should focus, tells you what rule you need to apply, and then if you're still stuck, it tells you how and why to apply that rule. This has actually meant that 99% I no longer need to use hints. This system embodies the saying "give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime".

Nearly perfect
I play killer sudoku mostly, and out of many apps I've tried, I really like playing on this one. The clean interface is delightful to use. Number input is dreamy. The coloured and arrayed pencil marks are really helpful. The hints are a great feature: they are intelligent, the prompts leave you with some thinking to do if you like that, and the direct help means you don't get stuck. I'd like to be able to turn off automatic clearing of matching pencil marks when you enter a number. Help with valid number combinations for cages would be nice although I must admit that not having that forces me to think more. Help with adding cage sums would also be nice. Killer Sudoku + has a good rendition of both these features, and is another nice app, but it does not have arrayed pencil marks or the excellent hints that are given here.

Genius interface
The best user interface I have ever seen in a Sudoku game. The use of color and position to stimulate additional parts of the brain is a great plus
Love this game!
I love love love puzzles and I've never found another game that's so thoroughly challenging and logical in nature. It's a shame it isn't more popular!
Already love it
Looks much more fun and colorful than most sudoku apps and has a good selection of games and an intuitive pencil mark interface
Add support for iPad please!
Nice app otherwise.
Best Sudoku App, by far
This is a real tool for players that are serious about Sudoku. There are many many puzzles at many skill levels. The amazing, amazing hint system actually teaches you how to play better. The app is super smooth and responsive at all times. No competition.
Excellent sudoku
Took a bit to get used to putting numbers in cells. Very much worth it. Great sudoku game. My favorite
Awesome!
I love this app. It is well organized, easy to use and extremely addicting
Great!!
Best sudoku app I've used so far!
Tons of puzzles, great variations, and the hints really help you improve your skill!!

well-crafted puzzles
This deserves to be more popular! Lots of puzzles in the App Store are computer-generated, but you can tell these are handmade. Excellent! Interface is clean and professional. Optional hints for those who like, and those who don't can shut the hint system off.
This is the best KenKen I've found so far. It's nice to have Killer Sudoku included also.
I hope that a future release might include larger KenKen (up to 9 by 9 would be super, and fitting with the "9 digits" name) and maybe a re-skin choice. I can see why Mr. Wagner went for colored digits, but I usually prefer a black-on-white scheme.
Update: I bought several of the extra puzzle packs when they cost a few dollars. Well worth it. Now that the dev has generously made them free, this app gives you a large number of really nice puzzles. Very kind!

Great!
This is great! It's good to be able to 'show your working' by adding in the little numbers - and it's easy to do. Love the fact that numbers are colour-coordinated so it's easy to spot what's missing. And I've just discovered the undo button - which is greatly appreciated when one's fat fingers hit the wrong cell!

Love this .... Play the killer all the time and have just progressed up to the professional level. Great for stretching the brain!
Best number game app!
Love this app. So many different variations on sudoku plus the ken-ken ones. Difficulty is definitely more challenging then other similar app's. That killer sudoku can really give a headache thinking so hard!
Nice game
Once you get hang of entering numbers it's a fab little game. Addition to free version of more levels at no cost was a nice bonus
Fantastic
One of the best sudoku apps out there, and it's free! It really should be more popular.
Useless
I could not get the hang of the selecting numbers and marking small numbers in the squares, definitely not intuitive. Deleted it after 5 mins.
Best sudoku type app
Great and challenging app with a variety of number puzzle games. I've tried almost every kenken and sudoku app, but this is definitely the best one! 4 games, 4 difficulties, 15 sheets per difficulty, and packages you can buy when you finally burn through those. The killer sudoku really IS killer!
Very good
Thank you
Doesn't work
Had three people ( are really good at sudoku) try same puzzle nobody could get it right and that's the easiest puzzle
