Sudoku: Classic & Variations

I have been playing this soduku game every morning for several weeks now and love it. No ads, progressively challenging games, ability to change the help you get to solve it. Plus if I end up finishing all the free games, to buy more is not outrageous. This is the first game I ever thought I would spend money to keep playing. Thank you developers!

I have been playing this and other Conceptis apps for years and I love them, but please make dark mode an OPTION instead of automatically adjusting based on phone settings. I have my phone on dark mode but that doesn't mean I want to play my sudoku with white numbers on a black background. It really strains my eyes and I don't want to have to go into my phone settings to change to light mode every time I use the app. I'm sure some people like the dark mode but if you give us a choice then everybody wins. Sorry if there is already an option to turn it off but I'm not seeing it.

This is generally one of the first apps I turn to when I have a few minutes to kill, or when I need to chill out before falling asleep. My only complaint is that on some of the Very Hard levels (at least in the Diagonal puzzles), you have to guess sometimes when there are no logical moves to make and you're stuck. You then either need to use the Assistant to verify your guess, or keep playing until you reach a logical inconsistency and have to go all the way back and guess something else. It kind of ruins the whole logical vibe of the game.
