I have thoroughly enjoyed the lectures and the attendant exercises. I feel that my game is getting better and the mental acuity that Sudoku requires is also evident in my thought process in unrelated things. Additionally, Sudoku has become a great stress reducing agent.

My hat is off to you as a teacher, mentor, and personal coach. You are not only expert in Sudoku, you also know how to put it across to your students. Additionally, you do not allow us to get sloppy (or stay sloppy) in our habits or to get discouraged.

I am very grateful that you have made this course available to us at an affordable price.

Best wishes,
