Description
Sudoku Extreme is a beautiful way to experience classic Sudoku puzzles for both beginners & advanced players! It's a great way to keep your mind active while relaxing to pass time.
Each puzzle has only one solution. The puzzle comes with a few cells pre-filled. Your job is to fill the remaining empty cells. Fill the empty cells with numbers 1-9 in a way that each row, column and block (3x3 cells) only contains a single instance of the number 1-9.
- No ads. No subscriptions.
- 6 levels - beginner, easy, medium, hard, unfair and extreme.
- It is highly customizable with many beautiful themes as well as settings to customize the app exactly the way you like it. App comes with both light and dark amoled themes to be comfortable on your eyes!
- The simple to use notes and hint features help you if you get stuck but we encourage spending time trying to figure out the puzzles without using hints. Cells filled with use of hints don't get any points.
- Haptic feature gives a positive vibration when correct and negative vibration when wrong answer is filled. This can be disabled in settings.
- If you make a mistake you can use the undo, delete and redo buttons. Note that each mistake deducts points from your overall score.
- Long press the undo button to restart the game
- After a game is finished, you get your overall stats like total time spent, best time, average time, overall score, hints used, mistakes made etc. Sudoku Extreme also comes with a graph of how your scores progress over time. As you play more difficult levels, you get more score. Each higher level gives twice the number of points as the previous level.
- Game can be paused and you can resume the previous game when you come back.
- Sudoku Extreme can automatically pre-fill the notes and auto-remove them when they are used in a row, column or block. Though we encourage disabling this setting and filling it manually as it makes your brain more active! Manually filling notes also gets you extra points!
- The quick fill feature lets you tap-and-hold a number and then simply tap cells and it will fill it with that number.
- Numbers show how many instances of that number are left to be filled in the puzzle. When a number has been used 9 times correctly, it hides itself. You can disable this setting if you like.
- You can swipe up/down to enter notes numbers quickly without having to enter edit/note mode (setting needs to be switched on)
- "Export Scores" from the app. This can be used in Excel.
- Advanced levels, Themes & Settings customization are part of a small one time only in app purchase. No subscriptions. No ads.
I offer a beautiful app free of ads, subscriptions, trackers and analytics for the absolute best experience for my users. If you are enjoying the puzzles, please leave me a positive rating on the app store as that helps get the word out to others! You can also purchase the one time only small in app purchase to help support development and future updates!

- Fixed a potential crash bug when launching a new game. If it persists, please email me.
- Fixed a bug where long pressing a cell with single note won't fill it if the note is incorrect solution.
- Fixed a bug where long pressing a cell won't work if a number is locked.
- Added two new themes - Chartreuse (on black background) and Blue (with white background)
- Added a blood orange theme.
- Added a new setting "Number-lock default mode" which locks a number by simply tapping it without having to long press. With the new locked mode on, you can tap the locked number again and that will unlock it. This is useful for those who prefer locking the number and then filling multiple cells as their preferred way of entry. This setting is OFF by default.
- Added a new setting "Start in note mode" which makes note mode on when a game starts. This setting is OFF by default.
- Added 2 new themes - Red on black and Pink on black.
- Fixed a bug where "when you lock a number, the numbers and notes are individually highlighted, but if you then enter note mode and tap a cell, you lost all of the individually highlighted notes." Entering note mode with locked number and then tapping a cell should no longer lose the highlights.

1. Fixed a bug where when using hold to fill in cell, if you complete the board, it wasn't triggering end of game.
2. Added a feature - you can now swipe up or down on the notes button to toggle hide/show the notes/candidates. There's also a new setting which can disable this feature. It's on by default and is called "Swipe or Long Press notes to hide notes"
3. Added a new setting - whenever a cell with either given or already filled is selected, it won't highlight the corresponding row, column and block. This setting is now on by default and is called "Don't highlight when given is selected".

1. Fixed an annoying bug where the animation or quickly swiping on the board after entering a number was preventing the number from being removed from the notes of other rows, columns and blocks.
2. Added a new setting "Haptic feedback long press override". If the "Haptic feedback" is turned off, this setting can be turned on to still allow haptic feedback when entering numbers using long press (when a cell has only 1 solution note left).
Merry Christmas and Happy New Year to you all!

Listening to user feedback:
- The "Long press to fill single option cell" now works for cells with only a single option in notes left too.
- Added a new setting "Long press to fill single option cell" which is on by default. If only a single number is left in that row / column / block or notes for that cell (note must be the correct answer), long pressing the cell auto-fills it. "This decreases finger stress (from having to go back to the number bar each time) and would make things a bit faster and more exciting." - Thanks Gregg!
- I have made changes to the beginner and easy level puzzle generation. It has been tweaked a bit to correctly reflect the difficulty. Before, many users mentioned that even the beginner and easy level was too hard. Now the beginner and easy level puzzles are easier.

- Small UI fix
- Added a feature to allow entering notes by swiping up or down on the numbers. Note that this is a setting which is OFF by default. If you want to enable it, switch it on and entering notes would be even faster by swiping on numbers!
- Added a setting to disable in-game animations. Few people wanted this as sometimes animations might slow you down when entering numbers quickly.
- Added a help button on the score screen which explains how the points are calculated. Hope this helps!

Apollolux,
Great with minor nitpicks
This is probably the most feature-packed sudoku I’ve found on iOS with tons of quality-of-life settings like auto-note at the start and highlighting cells with a chosen number/note. Long-press to auto-fill is pretty good, and I just found long-press to select number for single-touch-auto-fills.
The nitpicks I have are technological in nature though. Long-press (and probably even regular press) should allow haptic feedback, probably as a toggle; if I’m playing for speed then I can’t see if a cell is filled from long-pressing because my finger covers the entire cell so vibrating the phone would let me know the long-press activated. I also have an issue with animation blocking the ability to touch immediately.
I’ve found one legit bug though. With animation on, if you fill a cell (definitely with long-press, almost certainly with the normal way) and you cancel the animation super early (e.g. you accidentally slide your finger to the next cell too quickly from a long-press) the triggers of follow-up actions like erasing the number from the necessary notes don’t fire.
I currently can’t think of any other extras I’d like to have in a sudoku game, this one seems to have them all covered!

Dafaso,
Best sudoku I’ve found..a couple of suggestions
This is the best and cleanest sudoku I’ve tried. Well worth the one-time price. A few suggestions: 1. When I want to de-select all of the highlighted cells to see an un-highlighted board, I’ll click below the number row in the empty area of my pro max screen. However, the touch fields for each number extend so far below the actual number, that I end up accidentally hitting a number and filling in a highlighted cell - sometimes without realizing it - and it ends up messing up my board. 2. I like to play in dark mode. The border around the individual cells are very hard to see because they are almost the same color (or almost as dark) as the cell background color. Please lighten up the individual cell border color a bit. Otherwise when you have a lot of notes in adjacent cells, they all seem to just blend into each other and are hard to distinguish. 3. When you tap a cell that has notes (e.g. 1,4,7), the numbers 1, 4 and 7 at the bottom should be highlighted. Otherwise, good job.
CalBound,
Chose it for the Privacy; stayed for the Customization
Edit: I think the scoring system is broken at a certain point. Still a 5 star game, but until I can see the specific calculations for each of my highest scores, I cannot remove this. I read the scoring template and it holds true up to a certain point, then you’re capped
So many ways to customize this game! Was not expecting this. First app I’ve purchased in a long time. Great job!
I am curious about the scoring system because my friend and I cannot increase our score anymore. It feels like there is a cap.

BadWolf2112,
Probably my favorite sudoku app
I’m enjoying this version of sudoku. Most of the features that are needed in a sudoku app are here. The hard puzzles are VERY challenging.
I appreciate the automated pencil mark feature very much. The highlights are useful (though I do find some color themes to lack sufficient contrast).
I have a few suggestions for improvement:
The “coloring” technique is not an option on this app and it could be a very useful addition.
I sometimes use a solver to learn more about the extremely difficult techniques. It would be nice to be able to export the board in its current solve state to make that easier. Or, maybe the hint option can give a tutorial on the technique used to move you ahead, rather than just exposing an answer.

Shrikey,
Thoughtfully Designed, but flawed.
The UI is wonderful and clean, as well as instantly intuitive for Sudoku fans. The app has many novel features not seen elsewhere, such as pre-filled notes. It's clean and offers easy change of themes, which is nice- It's nice to see a developer recognize not everyone would like their first choice of colors.
Edit:
Apparently there has been an option added to toggle swiping notes off. That's a great addition, but it still doesn't totally alleviate the ease with which you can accidentally enter an incorrect number. Aside from toggling into note mode until ready to make an entry, that is still an issue. At least now my problem is incorrect notes, not accidental incorrect entries. To the Dev: I still love this game, but I consider issue where you can accidentally enter a wrong answer to still be fairly large.

KikiTheSunBird,
Really wonky levels
I bought this app because I liked the features and set up enough. But I increasingly regret it because the skill levels are truly bizarre. I don’t know how else to describe it. I’ve been playing sudoku for years and I usually play medium or hard levels. On this game, beginner is hard… and it goes up several more levels. It’s so strange. When I want to relax I like to ocassionaly play an easy level just to zone out for a bit, but that’s not possible on this app. If they’d fix this issue and make the levels more appropriate to their category, I would give it five stars. As is, I find it really obnoxious because I play most often late at night to relax and even the lowest level wakes me up because it’s a challenge. Seasoned sudoku players should be able to breeze through the beginner level.

Not Really a Free Sudoku App
I was looking for a Sudoku app that wouldn’t bombard me with 30-second unskippable ads like the others do. This one looks promising and offers many cool features but I think it is odd that I have to pay for the premium version just to play traditional Sudoku on what appears to be the ultimate Sudoku app. Specifically, the ‘auto-fill notes’ and ‘hide incorrect answers’ features are very cool but they are turned on by default and require a $4 app upgrade to toggle off. This is not a real Sudoku app to me. I ended up deleting the app without finishing the game I started because the auto-filled notes ruined the actual game for me. I would love to use this app as my main Sudoku app but I think I will stick to my plain paper Sudoku.
MontagFTB,
Brilliant Version of Sudoku
This is a great implementation of the game. The UI is fluid and intuitive, the score keeping is fun, and the hints help with deduction techniques.
I have two small requests: 1) can there be a preference to turn off the animation? Towards the end game of a puzzle the animation slows down a rapid-fire solving of cells as their possibilities whittle down to one. 2) for Hard (and beyond) levels, can we have an ‘auto-fill’ button for cells with only one possibility? My fat fingers have occasionally hit the wrong number filling in those cells and they’re counted as a mistake against me.
Keep up the great work! This variant of the game is my favorite on iOS.

Best Sudoku app on the AppStore
Since picking this version up back in July of this year I’ve logged almost 200 games in it. There’s a ton of options, and my favorite by far (well 2 now as of yesterday’s update) is that I can have all of the possible notes pre-filled!! And as of yesterday I can export my game stats so I can check them out in a spreadsheet and make my own graphs. Perfect if you’re a DataIsBeautiful redditor 🤘 If your old favorite sudoku app is boring you or if you’re new to the market and looking for a solid sudoku app, give Sudoku Extreme a shot 🤙 —mauirixxx
tincanmanios,
Great aesthetics but UX can be improved
Love the color schemes and overall interface design. The haptic feedback is wonderful. Definitely my favorite Sudoku app. There are two downsides:
1. The UX is not fast. When I click on a cell, it doesn't immediately select the cell and I can't immediately place a number. This slows down my fill speed.
2. When a number is fully used, the app should not allow it to be placed again. I've had multiple times when I accidentally hit a grayed out number which then counts as a mistake (usually when I'm trying to fill cells quickly toward the end of a game). This can definitely help reduce accidental mistakes.
Keep up the good work
