Sudoku

New Zealander Wayne Gould introduced newspapers in England to the Japanese sudoku number grid puzzles one year ago. Gould had stumbled upon a completed puzzle while killing time in a Japanese bookstore in 1997.

Sudoku is now popping up in newspapers around the U.S., addicting puzzlers everywhere. White Sox pitchers have admitted to playing while off the mound. British Airways even sent an email to its staff last week banning Sudoku puzzles.

Japanese for "the numbers must occur only once," sudoku is based on a game created by Swiss mathematician Leonhard Euler in 1783 called "Latin Squares." Wayne Gould is the author of several sudoku books, including "The New York Post's Sudoku: The Official Utterly Addictive Number Placing Puzzle."
