very good app

i love playing sudoku at night on my phone, but all the other apps are way too bright for me. i’m very glad someone made a dark sudoku. not only is it dark and easy for my eyes, but the customization is pretty decent as well. i would definitely recommend this to someone who likes sudoku, even if their preference isn’t dark mode.

This app lowers the volume of whatever you’re listening to, even if you have game sounds turned off in settings. It also turns the sounds back on any time you close and reopen the app. Even if the toggle shows that sounds are off, this app will make the INSANELY OBNOXIOUS clicking sounds until you re-toggle it off. The sounds are completely unnecessary and truly make this app unusable.

Thank you for your feedback, and I’m sorry for the inconvenience you've experienced. I really appreciate you pointing out the issue with the sounds and volume lowering. I want to let you know that this bug has been fixed in version 2.6.3, which is already ready for release. The update will be available on the App Store very soon. I hope you’ll enjoy the game more in the future. Thanks again for your patience and support!

Multiple errors.

The resume game is still broken months after the last review pointed it out. I’ve had a game where it appeared unsolvable and the show candidate feature confirmed it. Another game flagged no errors, but led to a situation where two different numbers had to be in the same position. On top of that it’s not that dark, so it basically worthless.

Dark sudoku, but so many bright ads

Dark sudoku is good. But the amount of ads has gotten out of hand and for some reason, for a dark game, all of the ads are so BRIGHT and they take up the whole screen before and after every game for 30 seconds each.

Fixed an issue where sounds would always turn on after restarting the game, even if they were turned off in the settings.
