User Reviews

Users mainly praise the ability to input Sudoku numbers by handwriting directly on the board and the slick, pen-and-paper feel, along with easy erasing and a generally fun experience. However, notes are a persistent flaw, being non-customizable and limited to certain candidates. Handwriting recognition can misread digits (8/9, 6/9) and erasing can be fiddly, sometimes letting errors slip through. Some wish for color-coded notes and more reliable input, and a few note that hint banking and error-prevention features have changed in newer updates.

Pros

Handwriting input lets you write numbers directly into cells
Slick, paper-like interface
Easy erasing with a double-circle gesture
Fun and addictive to play
Hints are helpful

Cons

Notes feature is restrictive and non-customizable, showing only certain candidates
Handwriting recognition can misread digits (e.g., 8/9, 6/9)
Erasing can be finicky and require repeated attempts due to motion controls
App sometimes allows errors even when configured to prevent them
Desire for color-coded or more flexible notes

Would like to be able to write in candidates.

So far my favorite sudoko app, I love that I can write in the numbers, it’s refreshing from all the other apps where u have to select the box then select a number. Erasing is easy with a double circle. My only issue is the notes. You give us only the numbers that CAN be notes, which is a border line cheat. For notes ALL numbers should pop up and we choose the note. other than that great app. Please consider the note fix in your next upgrade. Coming back for an update still my go to sudoku app, this app could be the number #1 app in the puzzle category but they don’t even care I believe. It’s absolutely fun being able to write the numbers.
