Book preview

This book would not have been written except for my introduction to Sudoku by a very good friend and my buddy, Mr. Carl Zaby. Not only did he introduce me to Sudoku but he actually gave me help with some of the ideas contained here, which I desperately needed. Thank you, Carl.

I am also extremely grateful to a lovely couple in my home town who, when I let it be known that I was playing with Sudoku, pleasantly announced that they too enjoyed the challenge of Sudoku. I had already drafted some ideas toward this book. Then, low and behold, after I told them about what I was doing, I ask if they would entertain the possibility of looking over what I had written. Sure they said. What an eye opening experience. So, Tom and Tricia Hewitt, thank you, thank you, thank you for your powerful open & creative minds. It has been such a pleasure and I hope you recognize the incorporation of your helpful red lines. I could not have done it without you both.

Most books containing Sudoku puzzles identify the level of difficulty (at the top of the page) which is applicable to the puzzle presented on that page. Generally, there are 5 levels of difficulty; Very Easy, Easy, Medium, Hard, and Very Hard. This book presents Logics that will almost always allow you to solve Very Easy, Easy and Medium levels of Sudoku (9) puzzles. These logics may aid in solving portions of Hard, and Very Hard puzzles, however, to solve entire puzzles you will need these and additional complex logics.
