I just want to thank you for a REALLY great website on how to approach the Sudoku puzzle. I quit Sudoku several years ago out of frustration because I could never get ahead when the puzzles got a little more difficult. But after taking your online course, I am back and loving it! I even bought the Nikoli Publisher’s puzzle book and having a great time solving the puzzles in it.
For anyone who want to know about solving Sudoko puzzles, Chad is your guy! He’s a great teacher and his website is so easy to use and so professional. Step by step he gives you lots of approaches to puzzle-solving that you would never figure out on your own.
Thanks for your great work!
