Great features

I’ve tried many sudoku apps and this is my favorite out of all of them. I love that you have the ability to change the sudoku board from white to black, as well as being able to change the background. I usually play it at night when I can’t sleep and want it dark as possible. I also love the haptic feedback and having the option to choose between highlighted block borders or highlighted block backgrounds.
