Almost perfect

This app is great except that for me, about 50% of puzzles in expert mode are solved by “singles chain”. So far none with swordfish, few with xyz wing. It’s either singles chain or a few xy wings. Personally, I am not familiar with singles chain and it appears quite difficult to perform on a phone.

Good, but strategy section needs work

I like this app, and it’s helped me learn more about how to play sudoku, but I have one big complaint. The strategy explanation section is really hard to read. The text is extremely light in color, and you cannot change the text size or zoom in to see it better. Even with my glasses on, I struggle to see the text, so the explanation is not very helpful. I hope the makers of this app will consider making the text dark in color and maybe bold type, as well as making the text size adjustable. It would also be nice if you could access strategy explanations and practice puzzles through a direct menu instead of only when you encounter them in a puzzle.

Terrible if trying to learn

Trying to learn sudoku and all this app did was make me more confused. Definitely NOT for beginners. Tutor implies teaching. This assumes you know already. That’s why I chose a tutor. Stupid waste of time for the name.
