Awesome app! Just 2 suggestions…
Oct 2026 update: Still here and loving this app! Thanks to the developer for continuing to keep the app and options fresh!
Update: I wish I could give 6 stars. Hats off to the developer! The app was just updated and I saw that the pen colors were added and the backgrounds were fixed for dark mode! That was a real quick turnaround and it shows the care that goes into this app. I’ll be recommending it to my friends as well. 13/10!
really love how the app functions. It’s simple and I liked that there was a one time purchase rather than a subscription. Best app I’ve found for my Apple Pencil for sudoku! I would just suggest maybe 2 more pen colors? The white and blue can be hard to see. Finally, not all of the backgrounds show up which is disappointing because they look like they’d be cool! Otherwise, fantastic job developers.

Thank you for your feedback. In v2.7 (out now) I’ve added some more pen colours and improved visibility of the blue pen in dark mode. The backgrounds should now be fixed 🙂 Glad you’re enjoying the app!
Sucky Update
The difficulty levels weren’t fixed with the new update. Please fix
Better before
This game was better before they upgraded it. Even the “Very Easy” puzzles are too hard. I’ll probably quit playing it.
I don’t like the new update
Bring the old version back
A fun game
This is a great app, but can someone tell me how to get rid if this killer cage thing and get back to the classic version? It got switched somehow and I can’t switch it back.
iOS 27 breaks game
Double tap a number, guess what your number you just filled in that is the only number that could go into that area on a new puzzle, meaning 1st or 2nd move. Double tap that number doesn’t go green. Double tap another number, now your number that you just entered, now lights up green. Double tap another number, guess what that last number is still green. Something broke!

Absolutely love this game, only one thing could make it better
This is hands down the best sudoku game I have ever played. Only one thing could make it better- I would happily pay for the game instead of getting ads. Maybe there could be the option for free w/ ads, or a fee for ad-free?
Response from developer
I’m glad you’re enjoying my app, thank you for the feedback 😊 The option for removal of ads already exists in the settings page within the app - I will investigate if I need to make it more obvious!
Fun
Just started learning how to play on the iPad while using the Apple Pencil. I enjoy playing the game this way. One thing I noticed is that there isn’t enough room to make notations around the board (outside the borders) but I’m glad there is at least some room.
Response from developer
Thanks for your feedback! In version 4 (just released) you can now turn on even more extra padding around the board in settings :)
Apple Pencil support - yay!
Simple and perfect!
Wow
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.
The best sudoku app, hands down
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!

Good
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.
Love this
No notes. Love the app.
The best pencil-compatible sudoku
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.
Amazing!!!!
This app is compatable with the Apple Pencil and is everything I could have asked for as a sudoko app on my iPad.
Need more options for visibility
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.

Brilliant app, very well made
Really well made app. Easy to share puzzles to compete with friends and works very well with Apple Pencil. Thank you!
Perfect sudoku game
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.

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.
Very addictive!
Thank you for making this game. I can't stop playing!
Perfect sudoku game
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. This doesn’t happen every time either.
