Checkers

Play Checkers online with players all over the world, or play with machine AI of 3 difficulty levels. Plays according to American Checkers/English Draughts rules.
Checkers (also known as draughts) is a board game played on an eight by eight squared board with twelve pieces on each side. These pieces may only initially move and capture diagonally forwards. Only when a piece is "crowned" or "kinged" may it move both backwards or forwards.
Players take turns making moves, the blue one always making the first move. To win, you must capture all of your opponent's checkers or block them so that they cannot move.
