What could be more appealing to Mensa members--or anyone who enjoys a good challenge--than a cunning test of intelligence and logic? That's exactly what these 250 puzzles provide. The trick to kakuro is in making it all add up: the game begins with a grid that looks like a crossword, except that some squares contain small numbers in the corner. Fill in all the empty boxes using the numbers 1 to 9 without repeats so that the sum of each horizontal set of digits equals the number in the black triangle to its left, and the sum of each vertical set of digits equals the number in the triangle above it. The kakuro puzzles start out simple...and get more difficult as the book progresses.

This popular, even more challenging variant of sudoku is for true puzzle warriors! Each one consists of FIVE sudoku grids arranged in an X-shaped array, with overlapping corners. No grid can be solved on its own; to complete the entire puzzle, players have to work on several grids at once, making their way to overlapping areas and constantly searching for new clues. While regular sudoku-solving techniques provide the starting point, the game's more complicated than that. Because the overlapping areas belong to two different grids, they must comply with the rules of both simultaneously. That changes the puzzle's underlying logic...and makes these sudokus more fun for the serious fan. An introduction, with a sample puzzle, shows all the strategies.

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.
