I am just learning. I am 82 and want to keep my brain active. So far I am enjoying it VERY MUCH. Thanks
Best app
ckimyt on 8/4/2018
This is the best Sudoku app out there...it’s amazing how the hints system guides you along to help you learn better techniques.
Helps me focus
Floridagurrl on 7/31/2018
Good game, multiple levels of difficulty. You can close it and return later with no penalty so it’s great for times you have to be waiting in real life.
Dust Behind Truck on 7/25/2018
I’m noticing that with repeated use, the games are the same, with only minor variations. I no longer find Expert interesting because SAME solution method works each time. Becomes a bit boring. Hate to complain because app is otherwise awesome.
yailug on 7/23/2018
I love this game it makes your brain work better and you can test how smart are you because you have to go against the clock but most of all it’s super cool
Brain Exercise!!
Terra 1012 on 7/22/2018
This game is mentally stimulating & a great warmup before jumping into a project.
Best Sudoku I ever played!

Entertaining but also challenging!

Best way to play
ltrst on 7/19/2018
I love this game. And being able to correct immediately makes it much more enjoyable.

I really enjoy this
Pop up ads
cappy tom on 7/16/2018
Pop up ads are irritating
mklano on 7/15/2018
I keep having to start new puzzles because of glitches where the lines are accepting duplicate numbers - and Ben the same number in a 9-square box :-(
unicorn pwr lol on 7/12/2018
It’s so fun
ynotsolo on 7/11/2018
I am 65 years young and getting better playing this game. I enjoy it immensely!
A decent sudoku app
Vercalos on 7/9/2018
But my main issue with it is the constant ads. There is no in app purchase or premium version to get rid of the advertisements.
Great game, crappy ads
Troutboy58 on 7/7/2018
First of all, I did really like the game. I have nothing bad to say about the game, per se. I accept ads since, sheesh it’s free. However, for this game. Ad to play. Stop, ad to continue. Ad leads to another ad. Ad, Ad, Ad. I’m deleting and using another.
Really learn Sudoku
Pete Babes on 7/7/2018
Autofill and a fantastic hint feature. With the 1st you play more games. Pressing hint doesn’t just add another number. In this game you are nudged into a row, column or box and walked through what you’re missing, what it means and why, and what it’s called. I’ve learned more in one week of using this approach than I did in the two months I used a different. An excellent app.
dottiemo on 7/5/2018
Several levels from easy to a challenge. Options to replay. Saves a game if interrupted. A nice little brain exercise .
fuxkinha on 7/5/2018
Great for your brains
Pretty fun
the yoyo man on 7/3/2018
It was many digits that were puzzling, but then I get it know.
Ad Nausium
Snobrd2 on 7/1/2018
Sudoku is a great game and this one plays pretty well. The play is spoiled by the terrible ads that come between each game. I understand the need for ads, but audio ads a the worst. They kill whatever music you might be listening to while you play. The non-audio ads aren’t so good either. They frequently require multiple hits to get rid of them.
The best
Happ Ulee on 7/1/2018
This is the best Soduko game I’ve ever played. The ads are amazing. It’s like the best day ever when I play this game.
Love it
Sweetness1989 on 6/30/2018
The game is fun, challenging as you want it to be anyway. Try it! I am glad it’s not small text.
Not safe for work
Bill Bruck on 6/29/2018
Great game 5 star but features random ads that are videos with volume turned on so everyone around knows you are playing a game. Not cool.
Great Stroke Rehab
What a Beach Baby on 6/28/2018
There are few things that are as challenging as word and math/numbers games and puzzles as sudoku is for me. It’s as close to a workout for your brain as you can get.
thickslym on 6/24/2018
So many ads
Boymom75 on 6/21/2018
The game is fine, but there’s an add between each & every game. Fortunately you get through the add pretty quickly.
So much better!
Snapdragonme on 6/21/2018
Love the light up when each number completes. So much better than hand entering in the paper. No more writing in the corners 🤨
Hate those video ads you can’t mute
Dolce4356 on 6/17/2018
Love the app but hate the ads, especially the video ads that stop when you mute them and you can’t fast forward through. You can’t play until you let the video ad play through. I’d happily pay to make those annoying ads go away. Were it not for the ads I’d use this app much more often.
@mlevene on 6/14/2018
Hadn’t played before, got bored with other games and came across this ap really never thought math could be this fun! Try it!! Seriously!!👍👍
Good game. It’s great.
Av.Bert on 6/14/2018
It’s a great
Updating My Review
The Monkey Eats Custard ;o) on 6/13/2018
This was and now again is the best Sudoku app! The developers responded quickly to an ad issue and sent a positive and helpful response to my concern. Thanks to them for keeping a great thing great!
Easy Fun

Fun—as always!

And, by starting with the easy puzzles, the grey matter starts to once again get itself back in gear! Yay! Very helpful !
Pastor Dude 62 on 6/8/2018
I’ve always loved playing this game. This iPhone version has provided greater challenge for me than my previous experiences. I am gratified to have finally successfully completed a “Hard” level puzzle. I think I’ll stay on this level for a couple more before advancing.
Awesome game
tos2ken on 6/8/2018
I never played electronic b4 but I got this app and it teaches you your mistakes which in return helps you to play better

Solving techniques
Krbartfay on 6/6/2018
Great app, just wish there was a more comprehensive hint or lesson aspect of it to help get your skills to the next level. I switch between “expert” and “hard,” but sometimes it feels the “expert” a lot harder.
Learn sudoku
Lance LB on 6/5/2018
Not know how to play this game I tried this app. After 5 games I have a grasp of the game and figured out a few different strategies for game play. Get this app if you want to learn how to play or if you are a sudoku master this app has you covered
Pop up ad HELL
phaelam on 6/3/2018
Deleting this trash.
This game is awesome
plotosikeoo on 6/1/2018
And so good because I’ve been playing this for years but it has to be one of your favorite games
Good setup
Chazapps on 5/31/2018
Good setup.
Tdub59 on 5/31/2018
App drains battery on Samsung G7
A Great Game
Antwerp7386 on 5/27/2018
This Is a well thought out game. However, you do need thin fingers.
MaryPat948 on 5/27/2018
Has ads before you begin playing every game. That’s OK, but now the ads are videos with loud voices. Not cool when you have insomnia and want to play. Suddenly a loud voice(s) starts waking your spouse. Bad form.
