This is my unwind in the evening game. Relaxes me before bed.
Best I’ve found: If you like Sudoku, this is a must!
Possumlady on 6/20/2018
Nice app, the best I’ve found for Sudoku after a long search. It’s fellow app Joy Sudoku is good for multiple puzzles. Great gameplay, extensive learning system/hints, and no intrusive ads. One feature I’d like to see is an option to limit mistakes. For example if you make 3 mistakes your game is over. That is just a feature I liked from a previous app.
Great Fun

AppCheck05012018 on 5/5/2018
This has every feature you could ask for from a a Sudoku game. Easy to get in and out of games. Plenty of tutorials and hints if you ever need help. Finally, the games are as easy or as hard as you want them to be with the various skill levels that you can select.

Bozwik on 4/8/2018
In my experience, it’s by far the most playable Sudoku for phone. Enjoy playing against myself for speed, and this game is designed for super fast entry of numbers.
Great app!
Unique names are stupid on 4/4/2018
It’s the best Sudoku I’ve found. Only wish I could input my own puzzle to solve.
Easy to learn the format
guyjax on 3/31/2018
I love this app. I can’t find anything wrong with. If you like sudoku then this is your app. I have another one but it’s way too hard to use. If you are a beginner this is the app for you. Great job in development.
ViH bari on 3/13/2018
No bugs. Work exactly how you want it to, almost no matter how that may be. Has advice to improve the game of the most expert. Reasonable number of free games per day. Advertising not annoying.
This app has SO MUCH MORE than any other.
averyRadish on 3/6/2018
Every element is better on this app than any other sudoku app. From the screen organization (it is easy and swift to move back and forth to notes), to the concise, amazing lessons. If you want to expand your thinking or game, this is the finest app.
Everything you could want
Fabermeister on 3/1/2018
If you like soduko puzzles, this is the app you want.
Recent Average ?
Fjfinlo on 2/5/2018
Sometimes statistics for Recent Average not reliable. Sometimes it increases even though my time for a game has improved.
Reliable mental play
Dynogyno on 2/1/2018
Have used this app almost daily for two years. It was easy to get used to. Relaxing. Low stress. It’s graduated difficulty levels help teach one or two tricks at a time. I note my scores are relatively slower on weekends. Suspect that math nerds play more often on their days off.
Renni25 on 1/29/2018

It is intuitive enough to make it very easy to use. There are enough levels to challenge even advanced players.
I love it! Better than the rest!
b<3dlady on 12/6/2017
The hints actually teach you strategy, instead of just giving you the answer. For further explanations, there are links. Makes the game more fun!
proione on 11/27/2017

ellenm1342 on 11/22/2017
Well thought out ap. East to learn. Hints are very helpful.
Great Program
Baby Chris Cobra on 11/17/2017
I've learned how to play Sudoku from this game. There are many levels so that you can learn at your own pace. There's plenty of help and tutorials with online links to teach you new concepts. The ads are not invasive at all. I'd recommend this program to anyone interested in playing Sudoku regardless of their expertise.
Great game
Rico Suave 69 on 11/15/2017
Works perfectly and has numerous game options.
Allanah313 on 11/10/2017
That says it all!
Great mental exercise
ViolinDream on 11/8/2017
Great mental exercise with intensities for the half woken brain to the one needing a challenge.
Casual player, found level of comfort via in app help
shortmancom on 11/6/2017
I enjoyed the in app help up to a playing level of Difficult. After that it stopped being fun for me so I play the daily new difficult level on many days each month. I could advance me skill more but I know I wouldn't enjoy any more than I already do. The in app help is very well done and easy to understand.
John39133 on 11/4/2017
Love this sudoku app. Works flawlessly. Like a good friend, it's always there when you need it!
