Sudoku – The Clean One is a Puzzle game from Priit Trink, first launched in 16th November 2018.
It’s rated 4+ and currently has 55+ ratings on the App Store.
What Makes Sudoku – The Clean One Stand Out
Sudoku – Pretty puzzling. A free and offline Sudoku app.
Presenting you a modern and rethought Sudoku design. By removing excessive details from the screen, we managed to create a fresh and clean look for the puzzle that we all love – at the same time sustaining intuitive gameplay and customization.
The user interface is minimal and fast – starting a new Sudoku or continuing right where you left off is just one click away. There are no loading screens. What is more, you do not have to worry about not finishing a Sudoku. If you are in a hurry, just navigate back or leave the app in any other way and the app takes care of saving your progress seamlessly. This for all difficulty levels separately.
So there you go! Choose your favorite colors and begin your smoothest and most elegant journey through endless amount of Sudoku puzzles!
Oh, and hopefully you love gimmicks. Changing the colors of the UI is not only available during the solving of Sudoku – you can do it literally from anywhere within the app!

Community Insight:
Our favorite sudoku app Ive ever played. Love the clean look and distinct difficulty levels.
One of our favorite games to pass the time. Priits apps are amazing, we love the minimalist design. Please share, so we can get the other games on iOS.
Ive been using this app for many years, and its absolutely amazing! The seamless design! The incredible intuitive controls. We cant play sudoku using any other medium. Even most other games sour because we wish the had UI this good! Thank you for an amazing product! We wish more people knew about this.
We wish we could hide the timer. Plus, the timer starts at 18 or 25 minutes instead of 0 minutes 0 seconds. All of our scoreboard times are incorrect :/.
Had this on Android and was hard to find when we switched to IOS. Less than 10MB. Clean, efficient interface. Minimal ads.
Our favorite sudoku app since its got a clean look, nice animations, and doesnt have any unnecessary features like other apps.
We switched from Android to iPhone and was so sad to discover that our favorite minimal sudoku app isnt available for iOS. Finally, we found this as the perfect substitute! Beautiful interface, the puzzles are actually hard, and we love the various dark and light color schemes available. Truly a joy to play, and we hope that others will find this app with more reviews.
Ive tried way too many apps, and this is the best one Ive ever used! None of the other ones have as easy of gameplay options as this one.
Had this app when we had an android phone and it was our favorite sudoku app. There are some other good ones on the App Store but we were too used to this one. We looked up the android app to see if it might also be on iOS and luckily it was, but we could only find it on here once we saw that its called The Clean One.
Very simple and easy to use and great visual. The only issue we have with it, is some bugs with the timer. Very frequently we have to restart the app in order to get the timer to restart properly. When we start a new game it starts the timer at the same time as our previous solve. If this could get fixed we would have no issues at all.
We have really enjoyed using this sudoku app on our phone, but the display just is not adapted properly for iPad. It looks like the phone display is just in the middle of the screen, and does not expand to fit the whole resolution of our iPad.
A good improvement would be the ability to edit multiple cells at a time another problem we see is the difficulty is too easy.
We have used a lot of Sudoku apps and this is our favorite of all of them. This was our go-to when we used to have an Android, and Im relieved its available on iPhone as well. The note-taking feature makes it easy to mark multiple cells at the same time, which is amazing for the advanced and expert levels. Plus, the minimalist design is pleasant and easy to navigate.
Attractive design, Smooth game mechanics, Beautiful color schemes, this app has it all. Ive been using it for about a year on Android and it is a must have for our new iPhone. 10/10.
There are an overwhelming number of sudoku apps in the App Store. Only a few of them are any good. This is easily one of the top 3, and the only one we use daily. It is minimal, but has all of the solving options we need, and is the only app Ive found with big chunky number buttons in two rows. This is our favorite feature.
We love sudoku puzzles and often get frustrated with other apps, mostly because of layout. And for a while we had a Samsung and downloaded this companys app. And we thought it was lost forever. And then we googled them, found their Facebook, and realized that we couldnt find their app was because there was only a handful of reviews so here we are writing a review so other people can find it.
This Sudoku app takes sudoku and makes it so beautiful, so intuitive, and so clean Ive lost hours to this app! We feel like our grandparents who play sudoku all day and we love it! We will never ever trade to another sudoku app after using Sudoku – The Clean One.
The cleanest and nicest sudoku by far! We just wish supported iPad horizontally.
Came from android. Best one ever.
Clean and sleek. Nothing to complain about. Love it a lot.
What reason is there for reading the contents of the clipboard on every launch.
Interferes with the sound on our phone, and not just during ads. Not in love.
