What is Sudoku?
From Wikipedia:
Sudoku (??, sudoku?), also known as Number Place, is a logic-based placement puzzle. The aim of the puzzle is to enter a numerical digit from 1 through 9 in each cell of a 99 grid made up of 33 subgrids (called "regions"), starting with various digits given in some cells (the "givens"); each row, column, and region must contain only one instance of each numeral. Completing the puzzle requires patience and logical ability. An early variant of the puzzle was published in a French newspaper in 1895 and may have been influenced by the great Swiss mathemetician Leonhard Euler, who likely created Latin squares. Modern interest in Sudoku stems from a revival in Japan in 1986, leading to widespread international popularity in 2005.
