It's nice to have dark mode, however I have to say the difficulty on this is strangely high. I'm no sudoku master, but I'm pretty good, & even on easy the puzzles are pretty difficult. Of the dozen or so other sudoku apps I've used, it's like the "easy" setting on this is equivalent to a "hard" setting on other apps. Just a bit frustrating. Ads are only a bottom banner, which is great. Difficulty is more my stupid brains fault, not the devs, so this is a good one for dark mode sudoku.

Edit : app is working again less than 24h after my review! Thanks! Used to be my favorite sudoku app but it doesn't work anymore, it won't open. I uninstall the app, restart my phone and reinstall. Still doesn't work after trying for over a week. Hope it gets fixed soon...

I'm sorry to hear that you encountered issues with the game. I always strive to fix all the bugs as quickly as possible, but unfortunately, I haven't been able to reproduce the problem you experienced. Once I manage to reproduce the bug, I will make every effort to release a fixed version as soon as possible.

I like Dark Sudoku because it is the only app that supports highlighting of candidates, to solve puzzles with Chaining Strategies. But I miss an option to scan sudoku puzzles from papers or websites to import them. There is also no option to import a sudoku puzzle scanned with another app.
