Best Sudoku app!
BillyCoe on 4/8/2018
I love this app. All levels of challenging games.
Played this since my iPhone 4
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
This is the best online sudoku game I have ever played. Its challenging and is easy to use with the least amount of key strokes. Love this one
CaptBobbo on 1/4/2018
Love it. Addicted! My favorite game of all time!
Slash789 on 1/4/2018

Very well thought out
JS luv on 1/1/2018
Easy to play, lots of help, from hints to displaying when a wrong number is used. Clear format. Uncluttered. Lots of levels of difficulty to try.
Excellent App!!

Excellent game
Ashokdev on 12/19/2017
Nice and correctly complex
Fun and challenging
Sparkynme on 12/15/2017
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
Great app for IPhone thanks
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!
Sudoku with the best features
dunk1904 on 10/29/2017
This app has features for the novice and the expert. It allows the option to elect helpful tools or go it alone. Has a good experience for any level player.
Great suduko app!
ABodes on 10/28/2017
Love the difficulty levels and pencil options! Great version of Suduko!!
Easy to use
Tcm8311 on 10/28/2017
I like the color option, nice touch when my brain just can't keep track of chains
My go-to sudoku
Jmcme on 10/27/2017
This game is brain food, for daily consumption. Helps me wind down or wake up, sometimes both. Highly recommended!
Great App!
RegulusBlk on 10/19/2017
I rarely write reviews but this app is good enough for me to do so. I highly recommend.
Great game
Bjavandel on 10/18/2017
Very good game.
Melper826 on 10/18/2017
Great Game - Really
Freewill365 on 10/17/2017
Easy to use, great puzzles that really challenge you!! You can stick to easy ones, or learn advanced techniques to tackle the nasty levels. Highly recommended.
THE best interface
Dvorcol on 10/17/2017
I’ve never seen a better interface than this. If I was going to add any features, I’d add the ability to input new puzzles - for example from the newspaper. Even if hints were unavailable (which wouldn’t be needed anyway), I just can’t do them with paper and pencil anymore.
Addictive challenge
PapaJ815 on 10/15/2017
Keeps my mind active with challenging puzzles! I'm enjoying the game tremendously!
The best Sudoku app
Thinn1 on 10/13/2017
The best sudoku app I've found. Lots of options.
Joan in Oakland on 10/10/2017
This is a great version of Sudoku with the option of hints when you want them.
Sudoku review
Grilo1950 on 10/8/2017
This is absolutely the best Sudoku app. Lots of games, easy to play. The tutorials are my only problem. They have a glossary of terms that I have no idea they are coming from.
dlong113 on 10/8/2017
Has everything a Sudoku app should have.
Excellent game!
Donnaxyz on 10/7/2017
I love the different levels, the way it auto fills used numbers, the hints, etc. The stats are great to see your progress also. GREAT GAME!
Great game!
Jdfpilot on 10/6/2017
This is one of those games I just never get tired of. Always very challenging but extremely fun as well. A perfect way to keep me occupied and my mind sharp. Great job!

Hotspotstopper on 10/6/2017
This app is so user friendly and very customizable! It seems to be endless the amount of "brain training" that I get ( being 60, it is important to keep that brain busy). If I have to find something negative to say, it would be you have to be careful that when you open it in public, the volume always goes to totally load! But, all you hear is key "clicking" and easily fixable with a quick volume down! Love this app!
A good app to learn and improve you sudoku skills
smithme7 on 10/4/2017
I like learning from the help, then using what I’ve learned to work my way up through the more difficult games.
Great App
Old Southern Geezer on 9/30/2017
This is a great App and a great way to exercise the brain.
Great game
Not happy noe on 9/30/2017
Always a brain tease. Never any problems with this game.
Challenging and instructive
Florida Pirates FF on 9/30/2017
Great fun and you can learn the more difficult ones.
It's the best! I love it!
Essoox on 9/29/2017
