The best.
The best Sudoku WEBSITE, disappointed that it's just a web wrapper.
Sudoku with no ads, a great learning progression campaign, and always more nine by nine content. The best of its kind as of yet.
love the website, love the app. learned so much! great interface
my goat best sudoku app and website EVER
I love sudoku but have dyscalculia, which means my brain mis-reads or just doesn't see numbers. This is the first app I've found that allows you to colour-code the numbers, including the candidates, and it has made such a difference in my ability to play. The lesson and hint system is also incredible, and I am learning a lot about the logic behind the puzzles and how to solve harder ones. I feel confident saying this is the one of the most accessible and pleasant sudoku apps out there!
Thank you so much for this wonderful Sudoku app Jan!! I kept searching for an app to play Sudoku without any disturbance aka millions of ads and this is just that. Thank you for the endless puzzles and absolutely love that you can learn how to play the harder levels. Thank you thank you!! 😁 Also when I searched sudoku without ads, your website popped up on top and I just thought "ahh I wish this was an app" and voila! I found the app in website wohoo. Thank you, absolutely enjoying this!! ✨
Love the app, sometimes it signs me out though, and sometimes it lags quite a bit.
excellent
so so so good!!! thank you sooo much for making this amazing app!
Absolutely amazing! I've been waiting years for something like this. There's nothing better for learning techniques as well as setting your own puzzles. Looks amazing too.
The definitive best sudoku app on Google play in my opinion. Great quality of life features, no ads, the lessons make sense, no in-app purchases. An explanation of the difficulties is nice as well. you can jump in and do puzzles at any difficulty, or grow your knowledge in the campaign. Would recommend to anyone.
best sudoku app you can get
I liked the campaign mode the most. it teaches all the techniques one by one.
I've learned more using this app in less than 2 months then I have playing other supposedly learning apps for the last year!
best sudoko app
Best sudoku app/website ever!! Thank you so much to the dev, I think this website is one of the best ways to learn sudoku techniques systemtically. Exposited with passion and love!!
it's the best way to learn sudoku. after learning the basics I never had the patience to learn anything more since the explanations are so confusing and long. This app + the website make it all super simple. I will say that the controls (both on web and app) don't hold your hand like other sudoku apps. Specifically, you have to learn to remember to change your notes as you place things down unlike basic apps that remove the obviously conflicting notes.
The best sudoku app! Free with all the features you need. Also has lessons and tactics
What a gem! It's literally the best way to practise sudoku and learn new techniques. If you are into classic Sudoku like me, I recommend starting with the Campaign and completing every single lesson. The interface is clear and nice. No ads. The tips are interactive and so useful. If I'm stuck, I can get tips one by one or see the solution, where everything is explained with great care. I feel I'm mastering mySudoku. I admire the efforts Jan the developer has put into this app! Thank you 🧡
Very good app for improving sudoku skills. It has a lot of customization options, decent UI, adequate difficulty curve for non experts, it's lightweight and it limits itself to being a just to the point sudoku app, instead of trying to reinvent the wheel like some other apps do. This is the first one I haven't felt like uninstalling it after a couple days of use
Superb version of Sudoku with hints for when you get stuck
Very good & helpful app especially to begin learning sudoku. The practice puzzles are plenty and the difficulty is beautifully increased as the theory get more complex.
Truly an impressive app. Clearly a lot of effort went towards it.
Amazing app and website from Sudoku Coach. No ads or intrusive permissions to deal with. It also works offline so it's great if you need something to do on a flight. You can customize so many things. No other app compares.
absolutely beautiful app. perfect for beginners and will give a serious challenge to advanced players.
Excellent Explanations, great layout. The best sudoku app out there. Just play or get full coaching. No Ads!!!! Just send a donation if you like it. so happy 😊
been always a fan of the way this guy does stuf will always suport, the ui is confusing at first but it is like picking up a new controller wonderfully implemented, I hope that he is doing well. plz add the option for an ofline mode where it only includes the basics and the campaign maybe a random sudoku genarator is the only request again thank you for the hard work and ad free experience
The amount of work that must have gone into this app is astronomical. Every feature I've thought might be helpful I was able to find somewhere in the settings. It's totally ad free, the hint feature is mind-blowing, and it teaches complex strategies in really digestible ways. Kudos and thank you to everyone who worked on this.
I love this app. the best app to learn techniques and practice. highly recommended to all sudoku lovers!!
Using it to learn the more advanced sudoku solving techniques. With a huge number of puzzles to solve at all levels up to Beyond Hell, it includes a campaign that takes you through each technique and provides an explanation, worked examples, practice examples, and at least a dozen games that use that technique to hone your skills. I would love to see a working save system for games and settings (I have had a few half-finished games wiped overnight), but I still think it is brilliant.
INCREDIBLY GOOD, very complete, totally free and ad free a solid campaign to learn techniques and an endless supply of both user generated and automated sudoku puzzles. endless fun and endless option, highly recommend and suggest to support this app and developer instead of more predatory ad-ridden apps.
v confusing to use
Best tutor - a lot of work has gone into this app. it really takes the time to break down the decisions, not simply by showing patterns, but with explanation. I have learned a lot from the Solver section and now solve hard NYT sudokus correctly. highly recommend
This works just like their website but better in my opinion. It's taught me to make more sense of patterns I naturally saw therefore improving my solving skills.
By far the highest variety of puzzle difficulty. Learning steps and a bunch of settings. No ads and small app.
This is the best sudoku app by far. I've been using the website version for almost 300 days straight and never learned so many techniques until I started using this.
I've been using sudoku.coach on the web for a long time and the app is great! It actually teaches how to solve sudoku, not just trial and error. The campaign teaches sudoku step by step, from basic to advanced techniques, with practice levels, boss puzzles, and an Endless mode for mastery. I'm over halfway through the campaign and can now solve fiendish puzzles without hints. Clean design, very customizable, easy to use, and genuinely effective.
