What a relief to find a simple version of Sudoku where the helper features can be disabled (like highlight selected number, highlight wrong inputs area, etc.). I want to use my brain to check my numbers instead of being assisted and this app makes that available as an option. The ads are very reasonable; they are either short or can be skipped after a short time. I find playing Sudoku on this app quiet and calming. Thanks for developing this classic version.

Ok app. No worse than the other half dozen I've installed and removed recently. My 2 biggest issues which seem to be common with all Suduko apps are twofold, (1) being able to see the board without ANYTHING highlighted. I want to see the board without visual distractions and (2) this app specifically doesn't allow me to select a specific cell to work in. With other apps, I can press &hold a cell, and the corresponding row/column are highlighted. I can't seem to find an app with these features.

Great port of Sudoku! I am not being bombarded with ads or fake clicks which is an issue i found on other apps. I really enjoy the helper setting and other personalizations as I am a beginner at Sudoku and it's helping me learn much quicker. I'm grateful for the different level challenges too. I only wish there was a setting to turn off (or maybe make invisible) the timer, as I like to play casually not competitively. Though, maybe the setting is there and I've missed it.
