Second-Degree Green Belt Sudoku(r)

This book is perfect for my skill level at Sudoku. It is not too easy or too hard. Easier puzzles are not a challenge for me and most books have differing levels in them so I end up only doing part of the book. This book is the right level from cover to cover.

I was afraid I would be wasting my money because the puzzles would be too difficult. I had started with the white belt edition and gradually worked my way up to this one and I am happy to say that I can complete these with little or no difficulty. I am working on the brown belt one at the same time and both are going exceptionally well. However, I feel it is because I developed good reasoning skills on the lower difficulty ones before tackling these. I might also add that I read the reviews of others who had done both the 2nd Degree Green and the Brown and with their encouragement, I was motivated to try them, too. Glad I did.
