Well each player picks a color to play, then they arange themselves around the table in the same order as the colors on the back of the cards. The object is to defeat the guy who has the oposite color as you (white vs. black, etc.) and you have the people on either side of you to help you out. The problem is that they are allied with the OTHER guy or one of his allies, so things get really interesting. Jester might know a bit more about it.
