This doesn’t happen every time either. Okay pros: highlight any number, everything’s free, ads do not bombard you (very few), auto note taking, auto error highlight, the option to turn those features off. You can write with your Apple Pencil and apparently 3rd party too. There are tips if you want to learn, and hacks if you’re a speed runner. Honestly worth the shot to try it, again it’s free. I paid for the app to show support. **Developer response:** Thank you for your feedback! I have addressed the highlighter issue you described in version 3.1 (releasing tomorrow), it should now allow strokes crossing multiple cells. ### 5/5 — Excellente mise à jour *2025-11-29, version 3.0* C’était déjà un plaisir de pouvoir jouer avec le Pencil, et les nouvelles fonctionnalités de la dernière mise à jour rende le jeu encore plus agréable à jouer. Merci :) ### 5/5 — I’ve played 1100 games on Expert level. *2025-11-17, version 2.15* Yes, it’s that good! :-) Get it, pay for pro. You won’t regret it. I play this nearly every day. Best sudoku game out there. The “Learn” mode is fantastic. Many thanks to the developer. ### 5/5 — Apple Pencil ile kullanılabiliyor. *2025-10-29, version 2.15* Apple Pencil ile kullanılabilmesi muhteşem. ### 5/5 — Great *2025-10-26, version 2.15* Haven’t done sudoku since high school this is great ### 5/5 — Amazing *2025-09-18, version 2.15* This app is exactly what I want. I love it ### 4/5 — Great experience *2025-09-14, version 2.15* I’ve played sudoku on my iPad and my phone for several years now,but whenever I tried to play using paper and pencil I struggled even with medium level games. Then I found this and it’s combines the ease of using the iPad with the bare bones of paper and pencil and I find it all the more exhilarating. ### 5/5 — 좋아요 *2025-08-13, version 2.15* 죄책감없이 놀수있는 앱 ### 5/5 — Apple Pencil support *2025-07-30, version 2.15* It’s great that it has Apple Pencil support. The Force Touch of the Pencil could be improved though. So could the backgrounds. Overall great! ### 5/5 — Great *2025-06-28, version 2.15* Haven’t done sudoku since high school this is great ### 5/5 — The best *2025-05-23, version 2.15* Amazing app ### 4/5 — Good, but needs improvement *2025-05-18, version 2.15* Easy to use, does everything I want. However I think it needs optimising, as it drains battery a lot and makes my iPad heat up. ### 5/5 — Absolutely the best sudoku app around! *2025-03-30, version 2.15* Works flawlessly with Apple pencil or any other iPad stylus I have used! I play every day and absolutely love it; so much better than typing out answers and annotations on an screen keyboard. Thank you soo much! ### 5/5 — Really great app *2025-01-27, version 2.15* Really great sudoku app. Was looking for something that was similar to doing puzzles on paper, and this excels. Simple and not too bloated. The features that are included work very well. I especially like the hint feature - the hints are very detailed and improve my understanding of strategies. I upgraded to the paid version since it is so well done. Developer suggestion- the “Expert” level has become quite easy. I would love to see more difficult levels added. ### 5/5 — Great game and use of the pencil *2025-01-20, version 2.15* I love this game, one thing I would love is the ability to input my own puzzle. That way I could play the newspapers puzzle on this great app. ## Most critical reviews (10 lowest-rated) ### 1/5 — Keeps force closing *2021-12-21, version 1.3* I really wanted to like this game. I have a new iPad Pro and Apple Pencil and every time I try to play the game it closes after using the pen. ### 2/5 — Too many ads and glitches *2025-01-26, version 2.15* Too many ads and glitches.it will keep randomly telling me that l put a number in error, but it is the correct number, so l frequently have to keep erasing and rewriting the number. I am using Apple Pencil, but my handwriting is clear enough. I literally rewrite it the same way and it works. Adds are a little annoying. I expect them to pop up when starting/ending a new game or opening the app, but there is an add every time you pause the game or go to the menus. ### 2/5 — Crashes *2025-01-08, version 2.15* I love the app but the new update won’t even let me open the app. It crashes every time I try to open it. ### 2/5 — Ads have become far too intrusive *2025-01-02, version 2.1* As the title states, having a multi-second add splashed on screen at the start of every new game, and at every Resume of a paused game, is far too intrusive. I will no longer use this app. ### 3/5 — Need more options for visibility *2026-03-26, version 3.1* I’ve been using this for a couple of days. I have a sudoku app that I’ve used for over 10 years but wanted one that works with Apple Pencil. This is easy to use. But I’m struggling with the puzzles because it’s difficult to see the font & colors. I am also finding that the hardest puzzles are not challenging enough. ### 3/5 — Latest update breaks notes *2025-11-29, version 3.0* Everything is green now for notes…. Same color as the correct number. Whatever you did broke the game. Otherwise it was fun while it lasted. ### 3/5 — App won’t open *2024-08-03, version 2.10* Love this app but since the update it won’t open so I can’t use it ### 3/5 — Paper Sudoku *2023-01-07, version 2.1* Does not show what numbers are left in the puzzle ### 4/5 — Good *2026-07-04, version 3.1* This is a great app for playing Sudoku. My only reason for 4 stars instead of 5 is that the “expert” level is not very challenging. I would love to see another level or more difficult puzzles in the expert category. ### 4/5 — Great app! Only one issue so far… *2025-10-02, version 2.15* I really enjoy spending my time with this app! It’s very convenient to use with Apple Pencil. The only issue I’ve run into is that it spontaneously corrects my “mistakes” even when the “correct mistakes” slider is off. It just turns this option on again which is annoying. Will give well-earned 5 stars once this issue is fixed ## Most praised reviews (10 highest-rated) ### 5/5 — Wow *2026-07-30, version 3.1* This game is amazing I am able to write the numbers in my own handwriting with my apple pen. This game is great when you are on a long car ride with nothing else to do. ### 5/5 — The best sudoku app, hands down *2026-07-12, version 3.1* This app is amazing! Tons of sudoku puzzles, clean UI, and the killer feature is being able to use the Apple Pencil. Even using it for notes is seamless, I love the new feature that automatically detects notes you write (even though my handwriting is awful lol). Highly recommend this to any fans of sudoku, 5 stars! ### 5/5 — Love this *2026-06-19, version 3.1* No notes. Love the app. ### 5/5 — The best pencil-compatible sudoku *2026-04-19, version 3.1* The “learn” function is so smart, and updates according to correct numbers I’ve placed. Hoping to get the highlight function that lights up an entire relevant row &/or column please. ### 5/5 — Amazing!!!! *2026-04-01, version 3.1* This app is compatable with the Apple Pencil and is everything I could have asked for as a sudoko app on my iPad. ### 5/5 — Brilliant app, very well made *2026-03-07, version 3.1* Really well made app. Easy to share puzzles to compete with friends and works very well with Apple Pencil. Thank you! ### 5/5 — Perfect sudoku game *2026-02-24, version 3.1* Okay pros: highlight any number, everything’s free, ads do not bombard you (very few), auto note taking, auto error highlight, the option to turn those features off. You can write with your Apple Pencil and apparently 3rd party too. There are tips if you want to learn, and hacks if you’re a speed runner. Honestly worth the shot to try it, again it’s free. I paid for the app to show support. ALSO DEVELOPER RESPONDED TO ME FAST, THEY ACTIVELY WORK ON THIS MASTERPIECE. ### 5/5 — Very addictive! *2026-01-10, version 3.1* Thank you for making this game. I can't stop playing! ### 5/5 — Perfect sudoku game *2025-12-26* I will give you the con before the pro; there is a glitch with the highlighter if you like to strike through whole lines when the boxes are more full.

The standout feature? Incredible handwriting recognition. You can write numbers just like you would on real paper. It makes the entire experience feel natural, fast, and incredibly fun. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
