Championship Checkers is a great version of this traditional board game. It has beautiful graphics, nice background music and a nicely tuned AI with multiple levels of play for fun at any level.
The game starts on an 8x8 board with 12 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. The opponent's pieces are captured by jumping over them. A player wins by capturing all of the opposing player's pieces, or by leaving the opposing player with no legal moves.
