Over twenty years ago Nikoli, the Japanese puzzle and game company, started publishing a curious logic puzzle called Sudoku. The rest of the world recently joined the Sudoku craze by using computer programs to create puzzles, but Nikoli is the only company that still crafts their puzzles the old-fashioned way: by hand. As Ad Age wrote in a profile, the Nikoli credo is ÒThe Best Puzzles Are Made by Happy Employees.Ó And for solvers, it really does make a differenceÑthereÕs an elegance and symmetry to the puzzles, plus a sense of interaction. The puzzle-maker knows just when to encourage, and when to withhold. Puzzles marked ÒEasy,Ó are easy because the puzzler leads you through. Those marked ÒVery HardÓ are exactly thatÑthey pit your mind against the mind of the master, who seems to share the joy of that moment when one hard-won number is captured, and the entire puzzle tumbles into place. An obsessiveÕs collection, More Original Sudoku features over 300 puzzles, all in a chunky, easy-to-carry format (it even fits into a standard jeans-size back pocket). An introduction shows how to solve the puzzles at various levels of difficulty, and it includes a tutorial on how to create your own hand-made Sudoku. HereÕs wishing you Gokouun o inorimasu! (Good luck!)

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.

Just when you thought it was safe to pick up a pencil Killer Su Doku is based on the original Su Doku grid, with the same rules and numbers—1 to 9—but with an added deadly twist. This time there is an element of arithmetic involved and there are few, if any, clues. The aim is to not only complete every row, column, and cube so that it contains the digits 1 to 9, but to also fill in the outlined cubes so they add up to the same number. Hints to solve the puzzle are hidden in the joined squares where only one combination of numbers applies. In the case of joined squares, if the printed number is 3, it should be 1 and 2 that go into the squares. Likewise, in the case of three joined squares, if the printed number is 6, the only combination possible is 1, 2, and 3. To add one final fiendish level, each puzzle also has a time worked out by its Japanese creators so you can try to beat the clock.
