While most books might have a few pages of introduction before proceeding straight to the sudokus, this one covers it all: hidden pairs, naked pairs, X-wings, jellyfish, squirmbag, bivalue and bilocation graphs, turbot fish, grid coloring, and chains. Every single one is here, and much more too, including the exclusive Gordonian logic methods (Gordonian rectangles and Gordonian polygons) that will turn even the hardest puzzles into a breeze. Of course, there are hundreds of sudoku for practice. A very special addition is a reprint of the very first sudoku ever published in 1979, from "Dell Pencil Puzzles and Word Games" magazine!"

Whether you are a complete beginner or have already acquired some solving skills, this book will be extremely helpful. For beginners it explains what Sudoku is, and deals fully with the basic solving techniques. For solvers already able to complete puzzles graded as Easy or Moderate, but who find themselves up against a brick wall when faced with more difficult puzzles, the book describes and demonstrates a selected range of techniques which will enable them to go further and solve all the puzzles likely to be encountered in newspapers or puzzle books, from Easy through Hard and Very Hard to Diabolical. There are 84 pages to explain the mysteries of scanning, matching pairs, twins, triplets and quads, pointing and claiming, the use of rectangles and other 4-sided figures, X-wings and X-Y wings, swordfish, jellyfish, turbot fish, and chains and loops. These explanatory pages are followed by 30 graded puzzles, ranging from Easy to Diabolical, with which to test the techniques described in the book. A novel feature is that the puzzles come with fully reasoned solutions and detailed explanations which, by taking you through all the logical steps, show exactly how each puzzle was solved and what solving techniques were used to do so. These provide in themselves a valuable aid to mastering the techniques..

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.

The sudoku craze keeps growing, with no end in sight--and as its popularity builds, fans keep an eagle eye out for fresh formats featuring their favorite puzzles. Here’s one sure to draw them in: sudokus that add a little spice to the mix by changing the standard 9 x 9 puzzles to 10 x 10. That means solvers get 100 squares to fill in instead of just 81! And the numbers go from zero to nine, rather than one to nine. Plus, the smaller sections within each grid are no longer 3 x 3: half the puzzles feature rectangular 5 x 2 boxes and the rest come in various random shapes, with heavy lines marking out the separate areas. It may seem daunting at first--but it’s fun!

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.
