The goal of Plunder is to collect the maximum amount of pirate booty, as quickly as possible. Each piece of booty has four attributes: number, pattern, color and type. To pick up pirate booty, you must make a group of three pieces where each attribute is either the same for all three, or different for all three. If two pieces of booty share an attribute and the third does not, then you can't pick it up! The game ends when there are no more groups possible to pick up.
