Version 4.0 is here: Killer Sudoku, quick 6x6 Minis, and more challenging hard & expert puzzles.
Sudoku is best on paper. Paper Sudoku is the only app that keeps it that way.
Write your numbers with Apple Pencil, in your own handwriting, exactly as you would in a puzzle book - then let the iPad handle the parts paper can't. No smudged pencil marks, no rubbing a hole in the page, no starting the whole grid again because of one wrong digit twenty moves ago.
NEW IN VERSION 4.0
Killer Sudoku, written by hand - cages, sums and all.
Mini. Quick 6x6 games, for when you have a few minutes rather than an hour.
More puzzles, and difficulty recalibrated from the ground up - with far more at expert.
Learn now walks you through advanced strategies step by step, showing exactly which cells each one rules out and why.
Writing rebuilt from the ground up: strokes land faster, automatic note recognition is more reliable, and games are far easier on the battery.
Paper Sudoku now speaks Spanish, French, German, Italian, Portuguese, Japanese, Korean and Simplified Chinese as well as English.
WRITTEN, NOT TAPPED
Built for Apple Pencil from the first line of code - not a number pad with handwriting bolted on. Pencil marks and candidate notes stay in your own hand, and when you would rather not write out a full set, notes fill themselves on demand.
FOR EVERY SOLVER
Highlighting to trace a digit across rows, columns and boxes. Check the whole grid for errors with a single tap. Unlimited undo and redo, so an experiment costs you nothing. And the interactive Learn mode teaches the strategies themselves, from the first scan of a grid to the techniques that crack an expert.
Unlimited puzzles. Every one playable offline, anywhere - a puzzle book that never runs out.
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.
Developer Response
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!
Best Apple Pen Compatible Sudoku App! <3
AshleeLC
This sudoku app is full of great features, and I absolutely love that the app is compatible with my apple pen! The learning mode is so helpful, and I love watching my average solve time get lower and lower as I figure out how to more effectively solve the puzzles. The ads are few and far between, so while premium isn't an absolutely necessary purchase to not get slammed by ads like with some apps, I highly recommend purchasing premium purely to support a great app and its developer(s)! Everything is beautifully designed, user friendly, and any sudoku lover, from beginner to expert, will get hours of fun and entertainment from this app. :)
Best ‘paper’ game for Apple Pencil
Pila808
This is by far the best implementation of an Apple Pencil interface for a game traditionally played on paper. Other games require you to write a particular way in a particular area of the screen and still occasionally struggle with handwriting recognition. In this app, the input is intuitive in that you write directly in the square, and your handwritten number remains on screen (though the app digitally converts it behind the scenes and changes color if the app is unable to recognize the number). Very accurate, very smooth, and the closest approximation to playing on paper.
Really great app
gutterlizard
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.
Developer Response
Thank you for your feedback! In the new version just released the expert puzzles are of greater difficulty- give it a go!
This update adds some of the settings you've asked for since 4.0.
PEN AND NOTE THICKNESS
Choose how heavy your handwriting looks, with a live preview as you pick.
BOLD DIGITS
Show the puzzle's printed digits larger and bolder, for easier reading.
HOVER PREVIEW
The Apple Pencil hover preview is back, showing where your pen or eraser will land.
NOTES
Matching notes are highlighted in the colour you choose, and undo now puts your notes back exactly as they were.
ALSO
Writing uses less battery, and you can attach up to five screenshots when you send feedback.
Thank you for playing, and for the feedback that shaped this update.
