Hi Chad: I enjoy your lessons very much. We get two newspapers and they each have a puzzle, so that keeps me busy most of the time. I also have a magazine of puzzles. Being an 86 year old, it gives me a great excuse to sit and WORK. HAVE A GOOD WEEK.

I just decided to learn SUDOKU and this puzzle is a big challenge for me but I determined to learn and I am enjoying learning something new to me. You are excellent teacher. I am slow but I will learn lesson by lesson. You deserve the praise from all SUDOKU fans.

My 6 1/2 year old grandson is enjoying your videos. He is learning Sudoku and is doing quite well. Jacob and I watch your lessons together and we talk about what we see. Thank you.
