The Official Book of Sudoku: Book 1: 150 All-New Puzzles - Paperback

The name of the game is Sudoku, Japanese for "number place," but no knowledge of Japanese language or arithmetic is required to enjoy the game that has sparked a mania around the world. It's a fever that is now spreading to the United States, as readers of the New York Post and Los Angeles Times can readily attest.

Veterans of other highly-addictive logic games such as Rubik's cube, Tetris, or Minesweeper will love the fresh challenge of Sudoku. It's a wordless logic crossword that leaves even the most dedicated puzzle enthusiasts scratching their heads. Here in one volume is all you need to get started--150 Sudoku puzzles (and solutions) along with easy-to-follow instructions and strategies. Solve these entirely with logic and you'll arrive at the right answer--but be warned: the more you solve, the more you'll want to play!

To solve, fill-in the blanks with the digits 1 through 9 in such a way that each digit appears in each column, row, and 3 x 3 box only once. You need numbers, but no math is involved.
