Comments on Open Sudoku for Android

★★★★☆ By Czy · Nov 20, 2025

Nice open source app. Great difficult modes and cool import of new XML sudoku.

★★★★★ Anselm Peter · Oct 14, 2022

This is the best Sudoku game in play store. I liked every aspect of game, levels, themes, highlight features and all others. Seriously loving it. Great 👍 job devs.

★★★★☆ Graeme Geldenhuys · Sep 19, 2023

I would have given 5 stars, if not for the bug. The bug being that it doesn't seem to always detect my incorrect input. Only later in the Sudoku puzzle do I realize that I made a mistake, then I have to use the "Undo to solvable state". Seeing that most of the time it tells me when I make a mistake, I assume this is a bug. Bug aside, what makes this app great is the multiple input methods, and the ability to manually input your own puzzles. No other sudoku app seems to allow for that! Kudos!

★★★★★ Steve Shanafelt · Aug 28, 2026

Ideal sudoku experience. Customizable, easy to access community content, no ads or permissions. It just works.

★☆☆☆☆ Nick Daniels · May 25, 2025

Input modes are buggy and messed up. Tick marks only have the option for all and have to be manually edited and that is also messed up and buggy. Who messed up this upgrade?

★★☆☆☆ Bludra Kuře · Mar 5, 2021

Color picker in themes is broken. I can't play, when even and odd cells have different color, and I can't pick black

★☆☆☆☆ Cate Malone · Nov 12, 2025

Please add the old color scheme, the new one is too chaotic, I cannot tell what's selected as colors are too similar I'm more than happy to change my review if these criteria is fixed please.

★☆☆☆☆ Steve Adams · Sep 20, 2024

Was brilliant, now rubbish. The latest update has completely spoiled a previously good app. I'll uninstall it now.

★★☆☆☆ Eddie Beasley · Sep 5, 2022

New updates to open sudoku are an absolute bust!!! New version has hosed all my entered puzzles and now will not work on 3 different tablets. Thanks a LOT
