Sudoku

In Japanese, su do ku means "one number." A sudoku puzzle is a grid to fill with numbers so that the numerals one through nine occur only once in each row, column and box. Each puzzle has some numbers filled in -- you just need to work out the rest using your powers of deduction. It may not sound like it, but it's really fun. In 2005, British newspaper The Times published a sudoku puzzle by Wayne Gould and the game's popularity boomed. Soon, U.S. newspapers were printing the puzzles and everyone had their heads down, crunching the numbers.
