'''Checkers''', known as draughts in [[British]] English, is a two-player [[board game]] played on a square board. The number of squares on the board varies - in the [[United States]], it is often eight squares by eight squares; in other countries, the board may be ten squares by ten squares or twelve squares by twelve squares.
Checkers move forward and diagonally, unless they are kings, in which they move diagonally either forward or diagonally. Only half of the squares are ever used, because a checker can never legally change colors due to its diagonal move, similar to the bishop in [[chess]].
In 2007, a computer called Chinook [[solved game | ultra-weakly solved]] checkers on an 8x8 board, that is, determined that the game is a draw with best play, but as of yet, no specific algorithm for bringing about this result has been brought forward. <ref>http://www.msnbc.msn.com/id/19839044/</ref>
