Packed with more than a hundred color illustrations and a wide variety of puzzles and brainteasers, Taking Sudoku Seriously uses this popular craze as the starting point for a fun-filled introduction to higher mathematics. How many Sudoku solution squares are there? What shapes other than three-by-three blocks can serve as acceptable Sudoku regions? What is the fewest number of starting clues a sound Sudoku puzzle can have? Does solving Sudoku require mathematics? Jason Rosenhouse and Laura Taalman show that answering these questions opens the door to a wealth of interesting mathematics. Indeed, they show that Sudoku puzzles and their variants are a gateway into mathematical thinking generally. Among many topics, the authors look at the notion of a Latin square--an object of long-standing interest to mathematicians--of which Sudoku squares are a special case; discuss how one finds interesting Sudoku puzzles; explore the connections between Sudoku, graph theory, and polynomials; and consider Sudoku extremes, including puzzles with the maximal number of vacant regions, with the minimal number of starting clues, and numerous others. The book concludes with a gallery of novel Sudoku variations--just pure solving fun! Most of the puzzles are original to this volume, and all solutions to the puzzles appear in the back of the book or in the text itself. A math book and a puzzle book, Taking Sudoku Seriously will change the way readers look at Sudoku and mathematics, serving both as an introduction to mathematics for puzzle fans and as an exploration of the intricacies of Sudoku for mathematics buffs.

Emeritus Professor of Mathematics Jerry Janusz presents a survey, step-by-step, of most of the known techniques used in solving Sudoku puzzles and illustrates them with many examples so that the casual solver may learn to complete some of the "hard puzzles" that appear in some newspapers and other publications. He provides twenty-five pages of instruction for beginners to Sudoku puzzle solving and ninety pages for more advanced players. The book begins with a description of three elementary techniques that will allow the reader to solve "easy" and "medium" Sudoku puzzles. Then more advanced methods that depend on "candidates" are presented. Techniques such as wings, chains, several types of reduction, almost locked sequences and others are introduced as part of the detailed solution of some difficult and diabolical puzzles. Some consideration is given to puzzles with more than one solution.
