well written mathematical view of a popular puzzle
on June 7, 2012
The authors are college professors in mathematics who also have extensive experience with sudoku puzzles. In this book, they cover a range of mathematical considerations from quite elementary to advanced, discussing sudoku puzzles from a number of different perspectives and drawing many interesting conclusions. In several cases, they analyze a smaller sudoku-like grid that uses entries only from 1-6 to simplify the math.
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.
