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.

Ratings and Reviews
Good but could be better
The puzzles are good and love the app’s focus on teaching how to solve puzzles.
It could do with some improvements however. The game centre reliance adds little. Every day I have to click through screens that say I was not in the top 250 in the world on the previous day. It’s rather disheartening and pointless. Also it requires internet connectivity to play or resume puzzles and it’s ridiculous that I cannot play sudoku offline.
Also would be good to be able to clear cells of notes.
Teaching me to enjoy sudoku more.
I’ve always enjoyed being bad at sudoku and leaning over and asking my wife to look and find where to put the next number or three. Now I’m enjoying being better at sudoku thanks to this great app. Several of zachs games are on my daily playlist so when I heard he was applying his skills (and jacks) to sudoku I was excited. It doesn’t disappoint. The daily challenges are there and all the tips and help you might need to get through even the toughest of challenges. The intuitive note taking options help so much and while it’s perfect for iPhone or iPad the skills you learn are easily migrated to traditional pen and paper puzzles.
Pretty good
The almost endless supply of games is great and it’s good that learners are able to get hints and tips as they progress. The interface function that lets you pick a number and see possible positions is very helpful.
However… I find a lot of the interface confusing – little beyond tapping a number and seeing where it can go is intuitive. I was hoping to learn clever ways of solving the puzzles but beyond the simple rules, but the tutorials are not that helpful. The “Y Wing” rule is explained in a few scant words and anything more advanced is just unfathomable.
Also, Expert, Pro and Advanced…they all sound like synonyms. Could the creators have not thought of a better naming scheme? There’s no “Medium” level even!
