### 1/5 — bright ads

*2025-12-20*

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

**Developer response:** 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.

### 1/5 — Game Sounds

*2025-09-30*

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.

**Developer response:** 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!

### 5/5 — very good app

*2025-08-14*

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.

### 1/5 — Turns my music down?!?

*2025-08-08*

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

### 3/5 — Please make the ads dark

*2025-02-27, version 2.5.0*

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

### 2/5 — Dark sudoku, but so many bright ads

*2023-08-28*

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.

### 2/5 — Gives you mathematically incorrect puzzles with no possible ending.

*2021-05-22, version 1.2.3*

I’ve come across a couple mathematically impossible puzzles, where it will tell you all your numbers are correct, but then you get to the “end” and there is no possible correct number for the last few boxes. If it weren’t for that, this would be a great app because I love the user friendly interface.

### 1/5 — Multiple errors.

*2021-04-26*

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.

**Developer response:** Hello! I am sorry for the inconvenience. The problem has already been fixed. Please, update the app to the latest version. Contact me at support@darksudoku.com if the issue remains.

### 2/5 — Broken Game Save

*2020-05-11*

It does not save my game very often leaving me at some previous point when I come back to a game.

**Developer response:** Hi! Thanks for your feedback. My apologies for these inconveniences. Could you contact me at support@darksudoku.com and provide more details (like the device model, OS version, steps to reproduce)? This information will help me a lot to solve the issue faster.

As a temporary workaround for this problem, return to the main screen each time before you leaving the game.
