word of the day: sudoku

Sudoku, noun. A logic puzzle in which numbers must be arranged in a grid such that no number is repeated in a row, column, or subsection of the grid.

For example, "The rapid and inexorable rise of Sudoku mirrors that of the great crossword craze of the 1920s and 1930s." (Source: National Review)

Note: Sudoku is sometimes also written Su Doku; it comes from Japanese elements meaning roughly "single number." Sudoku puzzles typically use the digits one through nine in a nine-by-nine grid having three-by-three subsections (called regions), but some versions use letters or colors, or differently sized grids and regions.
