The 19th Century board game is simple to play, difficult to win. Also known as Reversi, there are several versions. This is a standard one. You can play another person, play the computer, or watch the computer play itself (useful for learning, but not much fun). If you want to play another person, then you're better off buying a real board game version. Computer-recommended moves if stuck.
