Friendly Sudoku

I really like the flexibility of this sudoku game. For example, you can start with either the cell or the numbers first. The visuals make it easy to look at choices. At the different level levels of difficulty make it challenging for anyone I would think. It’s just fun to play.

Best version of sudoku among the apps!

Cell color options would get it 5 stars

Cell color options would be appreciated. Also I’ll mention the numeric keypad could be smaller, smaller buttons, so as to make a nice 3x3 grid.a. This is helpful when you’re going for speed. And last…the “hard” is too easy. Thanks.
