bright ads

i don’t see the point of an entire dark mode app if the ads are bright white and on the screen at the bottom the entire time. it makes it NOT easy to play on the eyes as needed

Response from developer

Thank you for sharing your feedback. I don’t have control over how ads appear, but the app does offer an option to remove ads entirely and permanently.

Game Sounds

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.

Response from developer

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!

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.

Turns my music down?!?

on my iPhone, why?!? I want to play Sudoku AND listen to music!!!

Please make the ads dark

I downloaded this due to insomnia because I can play a puzzle and get back to sleep without disrupting my brain too much with the brightness of my phone’s screen. Having a stark white ad at the bottom makes this game pretty much pointless. Please update this feature
