The book starts out with discussing sudoku. It begins with taking more simple problems and through showing forced relationships in simple settings, is able to set the stage for understanding some forced relationships in sudoku squares. It goes through basic strategies and solution techniques. Soon after though the book starts getting into more abstract settings with fewer rules and more possibilities. It goes through various ways of looking at solutions to Sudoku and it looks at the similarities of various sudoku squares. For example rotations of sudoku squares are analyzed and are quite clearly solutions in themselves as are any sudoku square who's entries are all shifted by the same number (with any 0 going to 1). It discusses some group theory and some unsolved problems in Sudoku.
This book discusses some Sudoku and more importantly discusses how Sudoku introduces many interesting mathematical problems. Some of these mathematical problems are what the book explores. The book definitely motivates the readers ability to do some interesting math with a very concrete object and makes the learning process easier and more natural. Despite not being what I expected, i am really glad I picked this up.
Also enjoyable are a number of unsolved puzzles of various sorts, some quite unusual or advanced versions of the sudoku puzzles published in daily newspapers, etc. (with complete solutions provided at the end of the book).
Anyone interested in the mathematical underpinnings of these ubiquitous puzzles will find this book a worthwhile read.
Not to worry. It soon became evident that Rosenhouse and Taalman were using these other types of puzzles to cast Sudoku against a broader backdrop of puzzle solving, and the book is greatly enhanced by this approach. Let's face it, one big problem faced by ordinary Sudoku collections is the sameness of presentation and typography. "Taking Sudoku Seriously" nicely sidesteps this problem not only by the "adjunct" puzzles, but also by the way in which the authors highlight the wide variety of Sudoku-type challenges that have evolved during the genre's still relatively brief history. The result is a book that is both comprehensive in content and diverse in its displays. The use of color is both welcome and purposeful.
Perhaps the best thing I can say is that I'm not even a Sudoku nut and I enjoyed every page. The revelations of this book make Sudoku more interesting, not less.
The author used color to aid in some explanations and I could not see that on my Kindle. So I stumbled around the Amazon website until I found Kindle For PC and I downloaded it. Now I can read all my Kindle books on my PC as well as my Kindle and I can see the color book jackets and any color pictures that are included in my books. Also, I could probably have printed the many puzzles in Taking Sudoku Seriously from my PC to get a paper copy to work them. I chose, however, to make copies of a Sudoku template and make the paper copy of each puzzle by hand. Perhaps other Kindle users would be happier with a physical book to write in.
In summary, I enjoyed this book because it gave me a look at the many details that are behind the Sudoku puzzles that I like to work.
