The Best

I had the LTE version which I have played for years but decided to upgrade to the paid app. Same app just more puzzles and colors available which is a very nice feature. This is, by far, my favorite app for Sudoku so much so that it is the only one I play on all our app devices. I’ve tried other ones but always remove them and come back to this one!

This sudoku is the best I’ve found. It has a simple clean look and is a fun way to pass the time. It’s my go to game on my phone.

Been playing it for years. 1000 distinct beginning grids, 250 at each of four levels of difficulty. After doing all of them, I reset stats and start all over. Will never run out of grids.
