Not working
I loved this app but it seems it’s no longer being updated and just crashes all the time :( I just paid for the full version to try and fix it but no luck!

We put everything we could into making the best digital Sudoku game ever released:
- We wrote a puzzle generator from scratch to create over 70,000 of the highest quality puzzles you’ll see anywhere. We spent weeks figuring out how to generate intricate and complex puzzles you won’t find in other Sudoku apps. Our hardest puzzles require wild techniques like “XYZ Wings”, “Hidden Quadrouples”, “Jellyfish”, and “Swordfish”.
- Most people don’t know this but Sudoku puzzles are actually generated by programatic Sudoku solvers. The fastest way to know how hard your puzzle is, or if it’s valid, is to write a solver that knows all the strategies that can try it. With Good Sudoku, we run our solver as you are playing, so if you get stuck, it can detect what you know by looking at your answers and your notes, and then help you find the next technique you need to solve the puzzle.
- Most Sudoku games classify difficulty into vague Easy, Medium, and Hard difficulties — But what do these difficulties mean? Typically they refer to the kinds of solving techniques that are required to solve a given puzzle without resorting to guess-and-check. In Good Sudoku we aren’t vague about it at all. We lay out exactly which techniques are required for each difficulty level. Good Sudoku allows you to practice them individually outside of puzzles, and keeps track of which ones you’ve learned!
- When we first got interested in Sudoku we noticed that a lot of players spend most of their time looking at the board and counting. On easy puzzles, this counting serves as a way to increase the difficulty by making the puzzle take longer. We know some sudoku players love the counting but we found it a bit tedious and designed some tools to alleviate the busywork. At first these tools might feel a bit like cheating, but once your mind is freed up from counting you’ll have space to see the much deeper more fascinating side of Sudoku: all of the beautiful technique structures. Freed from the burden of busywork Sudoku becomes one of the best search-style games we’ve ever played. More fun than word-searches and solitaire, high-level Sudoku is a real treat — and with Good Sudoku and a little practice, anyone can learn it!
- We noticed when looking at other Sudoku apps although there are often daily puzzle modes, those modes never include global leaderboards. Weird! Good Sudoku remedies this problem!
- We wanted to make the best Sudoku out there, and while we’re proud of our puzzles, we recognize that puzzles come from all places. That’s why we built a quick and easy custom puzzle mode into Good Sudoku, so if you have a paper puzzle that you’re stuck on, or you’re trying some wild variant (Like the Miracle Sudoku!) it’s easy to put it into the game, play it, and share it with your friends. If the puzzle follows standard Sudoku rules, our hint system will even help you get unstuck!
We truly hope Good Sudoku can introduce you to, or deepen your love for this great game.

Achievements not granted
Completed 365 day streaks last weekend. Achievements still missing… How can this app still run and not have been updated for so long?
Will not back up to iCloud
Never been able to get this to sync which means I’m stuck playing it on the old device I started out with or lose all my badges and streaks. Otherwise, nice way to start off the day.
Fantastic app; wretched interface
I have paid money for the premium version of this app. I would pay money for it again. I would absolutely not recommend that anyone else pay money for it, and I shall tell you why: The crux of this app, its whole reason for being, as stated by the developer, is that Sudoku as a game suffers from a bit of an information overload if you're trying to track the board state. Good Sudoku does its stated job, and makes that much, much easier. However: it uses game centre for literally everything, and when game centre is doing ANYTHING (signing in, updating, etc), the app is brutally unresponsive. Also, it uses an absolutely laughable amount of battery for an app whose sole job is to print some numbers and rectangles. I get WHY it does this, but I am still relatively unsympathetic. Most unforgivably, though, the "Good" UI is *inconsistent*. The whole point is that I'm supposed to be able to drag-select some boxes, and highlight (or cross out) some numbers in them. The fact that the app decides that I am done this before I do, and exits highlight/cross-out mode while I am still selecting numbers? What even is that? This wouldn't be a huge deal except for the big obvious case where it is: arcade mode. You're sitting there doing your job happily, and then suddenly the game decides you're done crossing numbers out, and the next one you press is treated as an actual input, and suddenly you've input an incorrect number and you're down a heart. Also, the hint button? Criminally close to the cross-out button, such that it is very easy to go to cross out some numbers, and instead waste a hint on the puzzle that always turns out to be something incredibly banal like a hidden single. I guarantee you I saw the hidden single, but I sure would have liked to cross out the numbers around it! I will gladly, happily, enthusiastically change this review to a "5/5 no notes" if smart highlighting or whatever it's called gets fixed. I can live with the rest, and I've spent an enormous amount of time playing this game, and I will continue to do so. But please, please, for the love of everything that is holy, if the UI is supposed to make the game easier to understand, just make it behave consistently.
The best sudoku game on iOS
Once you quickly get used to how the app works, there’s no going back to any other sudoku apps. Definitely worth the price. I recommend it to everyone I know.
Love it
love this app but sometimes the squares will just randomly remove auto note on specific ones and i can’t stop it. still love it though!
Crashes often
Love the app but it crashes every couple of minutes…
Used to be great
Now it crashes frequently, erasing most of my notes. Please fix!
Crashing every few minutes
I love this app so much. But it’s basically unplayable with how frequently it crashes. Please fix!
High-Five
Your games are simple and addicting. I am not one to pay for apps, but you have broke me! My only suggestion would be adding Game Center syncing across devices. Looking forward to your next game development and me having to crack open my wallet again!
