Are You A Sudokulist?

November 3, 2005

Sudoku is a crossword puzzle for people who like numbers. The object is to fill a 9×9 square grid so that each row, column, and 3×3 sub-grid (or “region”) contains every numeral 1-9.

The game is based on Latin Squares, a puzzle created by famed Swiss mathematician Leonhard Euler in the late 18th century. The name Sudoku means “numbers single” in Japanese.

Here’s an example from The Daily Telegraph of London. You can click on the smaller box below to see a full-sized version of the answer.
