It's a great Sudoku app. I've played many. And most are great. I like this one especially a little bit more because when you click on a number it shows and highlights all the other numbers on the grid. The one thing I would change is have a different font style for the numbers you put in place. They basically just use a different boldness for the one you put in place. I like the fact that they have different grids not just your standard 9 by 9 by 9

I really love this app, keeps me entertained when nothing else will, but, this morning I tried to Auto-Sync my progress between my phone and my Android Tablet, and for some reason, my PROGRESS WAS WIPED BACK 7 WEEKS! What the f***?! I had 25 puzzles done in each of the Standard Variation Categories, and when I synced, it wiped me down to 10 in each!? I WANT MY PROGRESS BACK!

Great app, but the daily averages of other players should be only for the particular puzzle that has just been solved, rather than all puzzles. It's not very interesting to know how you've done against all other's average times that day when it's not puzzle specific.

Well designed, easy to use, different levels suited for everyone. Adverts aren't invasive, for a free version of an app someone spent their time on, for us, they need the revenue from adverts and it doesn't bother me. In other apps they can be very annoying.

I like this app but it is rather power hungry and the ads are annoying. I would consider going ad free if it wasn't £7.99 which seems rather expensive considering other Sudoku apps charge£1.99.

Wonderful game! Simple to play, but can change difficulty to more challenging. Makes me think. Easiest one I've seen to make notations in the squares. Although I enjoy doing it from memory instead of noting boxes with only possible numbers.

Fun game, but recently I've been getting pop ups saying that "Google" has detected an Android virus on my phone. These are obviously fake and are likely attempting to get me to install malware on my device. The pop ups are coming from ads within this app. I recommend people find another game that won't serve ads trying to infect their phones!
It's fantastic application. I have only one comment, hopefully you can include advanced ways (i.e xwings...etc.) to solve complicated puzzles via clarification videos.
My brain has never been so well exercised. I added Sodoku to my growing list of games I use to keep my brain sharp and healthy. Sodoku is a game I enjoy immensely! It's a real teaser! ENJOY....
Absolutely hate trying to fill in a puzzle. You have to select the square you want, hit a number then hit it again? I'm not even sure after finishing a puzzle. Don't change the number if you haven't moved squares first, it'll change too. Horrid controls.
Ads are beyond annoying! You can't mute or close them while playing and keeps repeating over and over again 😒🔫
I enjoy Sudoku and this is much better than waiting on one in my daily paper! Plus, the difficulty level flexibility is a big plus. Great app - this is the best one I have found. Thanks!
Fun, stress reducing. Love being able to select difficulty levels and see how quickly I was able to solve puzzle compared to other players. Never have any issues like freezing or glitching.
The puzzles are great but the new controls slow gameplay quite a bit, pencilled numbers don't highlight when there are more than one number in the box so you might miss something you would have seen in the last versions. Going to see if i can find a different sudoku with fewer advertisements.
I didn't get a chance to play. You want too many permissions given to Google play services. I hate that. They, and you; have no right to my CONTACTS, MY PHONE, MY MICROPHONE, MY BODY SENSORS, MY SMS (TEXTING), or MY CAMERA. SO I DELETED YOU. Have a nice day. 😊
One of the better Sudoku apps, let down by seriously buggy achievements, invasive ads and a competely ridiculous and overly priced premium pricing strategy. A subscription for a Sudoku app, really?!? But really, the bugged achievements are what really bother me most. Please look into them and fix.
I am fed up with errors in your app. Year 2015 I started playing your mobile app sudoku in 2015. I played 166 hours, completed 532 games, won 1730 gold. It is listed under Leaderboard. I accomplished 30/60 achievements. It is all mentioned under my login. Then one day ALL the games I had completed, disappeared from my mobile app. I felt so angry, frustrated and sad that I stopped playing sudoku. Year 2017 I again started playing your mobile app sudoku in 2017 in my new mobile under the same login. It showed my year 2015 scores under Leaderboard. This year, I played 140 hours, completed about 550 games, won 1470 gold. This is shown in my mobile app. But under Leaderboard, it showed my year 2015 scores. Then yesterday ALL the games I had completed, again disappeared from my mobile app. App shows only the number of hours and gold won. I was playing online games when this happened. I am mad at your app. You cannot create such a clumsy app where the player looses his years of hard work. Do you have any remedy ? How can I get ALL my scores back ?
It's perfect. The other apps advance too fast. I like the super easy sometimes just for fun. I'm not trying to bust my brain all the time, ya know?
For the price excellent game.. No serious hang ups with the app and plenty of fun. Ads do get in the way however it is free.
Sometimes it's hard but still giving challenging spirit. Less adv will make it less annoying .
I just downloaded this since I got my s8. I had a s4 previously and had no problems but on my s8 it is not stable and crashes constantly. Very disappointing
Except some pencilled numbers retained even after a regular number is filled in the box row or column and some times check puzzle not enabled offline, the app is perfect compared all such free apps of 9/9 Sudoku.
The controls are lousy. Theres no clearcway to delete entry. I have to highlight/ hit too many selections to do one entry. The game play isnt fluid. The TRUE PUZZLE IS HOW TO USE the Number/note/erase buttons.
I installed the same sudoku app but it was so heavy. I like this one, not so heavy tho 👍
Unhappy. The game keeps running by itself and using battery. I have not played in 2 days, exited properly, and have killed it twice in the last 3 hrs. Pls fix this. I'll have to uninstall if this continues.
I really wish I could revert to the earlier versions. Color schemes were MUCH better without that bright blue bar on top, number highlights were better. Now a cell with only one pencil mark is not highlighted anymore and highlights are so bright that it's almost impossible to see anything in a cell in dark mode. And what the hell is going on with so many ads? I understand they help developers, but the number of ads is too high now. Ads when you open the app, covering a good part of the puzzle screen. I really liked this app, but this last update screwed up bad. If you haven't updated yet just don't!

Hi, I'm very glad to hear all your complains, about the pencil mark highlight you can enable in the settings, we'll refine the highlight cell in dark mode in next release.
And if you find any ads were not acceptable, just tap on the 'x' in the corner or send us the screenshot.
And we really value our players, your complains help us make it better! It is not a sure thing when I pushed the pencil button that it would stay on pencil mode until I say ink. It seemed to jump to ink on its own....
Don't like other games flashing up with really loud irritating music! Especially when you complete a puzzle. Otherwise its a fun brain teaser
Like the game and all the different boards. Ads are annoying but at least short.
Keeps me going I love the challenges. It's hard to stop i just have to solve it first. Even when i need to use the bathroom I sacrifice myself.
I recommend this game to you because it is really fun to play and usually in the paper is a sudoku puzzle and I and my family solve it and I enjoy myself and you can to if you download this app and to make you want it even more there are hardly any adverts 😍😃
I am hooked !! Play anytime, easy to use. I can relax, taking my mind off difficult problems in my life xx
Would like to be able to choose the difficulty of the games, I'm not super at this but I really don't want to go through 500 very easy to get more difficult games like medium.
Notes option and automatic clearing of notes when option is no longer available is really helpful. No game freezing.
I love it but dont really get how to put more than one number in a box, it would also be better if you could delete a number without having to delete half the game
While one of the better Sodoku apps I do find the controls counter-intuitive which causes me to have a high error rate! Please fix the controls! It would make more sense to select a number via the numbers at the bottom rather than trying to find the number in the grid.
The most perfect Sudoku app available. The squiggle puzzles aren't easy to find anywhere. I highly recommend this app and highly commend the developer(s) for their ingenuity.
Just learned the game Saturday. It took me a few times before I understood it and got quicker at it. Now I'm addicted to it!
A good sudoku app for passing odd moments. I could live without the stats page as I play for relaxation rather than competition.
Why would suduku be scary?.... No matter, its an awesome game. It's a nice brain teaser first thing in the morning
