The Mammoth Book of Sudoku: 400 New Puzzles - The Biggest and Best Collection of Sudoku Ever

This will keep you busy for weeks if not months. Nice Collection of Sudoku puzzles.

This book is so good, even my 7 year od daugther learned how to play this game.

Su Doku is a Japanese logic puzzle where rows, columns and regions must contain a certain number of digits only once. Su Doku has risen in popularity and an almost alarming rate and as such has been targeted by many variations. In a typical Su Doku puzzle, number digits appear only once in each row, column and region. These vary from the simple 4X4 grid to mammoth 16X16 monsters. But there are more variations awaiting the dedicated puzzler. Although this book does not contain the variation dubbed Killer Su Doku, it contains many others as well as related puzzles. The book begins with simple 4X4 puzzle grids and moves up through 6X6 and 9X9 to 16X16. Many of these puzzles will use letters from a word or symbols instead of the tradition numerals. Some even change the shape of the regions adding a new twist. We also have Samurai grids with five overlapping 6X6 grids. After that there are Slitherlink puzzles where you box in numbers following clues to how may sides are fenced in. Next there is Patchwork which works like Su Doku but has no region and uses a handful of clues relating specific boxes to one another like in a classic logic puzzle. As if that wasn't enough, there is also kakro which looks like a crossword puzzle but with clue showing what the rows and columns add up to. Finally there are the Super Su Doku that follow the standard 9X9 grid and are supposed to be tough. All in all this is a fascinating book with good examples of standard Su Doku puzzles with some nice variations thrown in to keep things fresh and fun. An excellent all-around Su Doku puzzle book.

I stubmled across SuDoku about 3 months ago in a local news paper and was boggled by it. I threw it to the wayside. Shortly before the thanksgiving holiday, I realized I'd have only one game on my PDA for a long road trip. I downloaded a PDA version of the game and was hooked on it once I figured out how to play it. Subsequently, I got my wife (who is a math teacher) hooked on it. While at our holiday destination, I dipped into a local borders and found this book. It has LOADS of puzzles going from simple to just down right evil. Very enjoyable. I'm not sure I can handle the 16x16 puzzles.

I love Sudoku. I went to Barns and Nobles and found about 25 different books and I went through them all, and picked this one because you get 400 puzzles that range from super easy to extremely hard. Also, there are different types of Sudoku puzzles that I didn't see in the other books that are really challenging. some puzzles use 9 letter words instead of numbers; some use shapes; one uses a fragmented LCD font and not only do u have to solve the Sudoku, but the extra challenge is thinking the number is something it isn't. There are also logi-place puzzles where instead of a cube it uses different shapes...much more challenging. There are also monster sudokus with 16 columns instead of the regular 9. There are also other types of Sudoku puzzles. So if you're getting tired of the regular 9 column ones or if you're up for a real challenge then you NEED to get this Sudoku book. Sometimes I like a challenge and sometimes I want something simple. This book has it all. It's the best i have found so far. 11-7-05
