Players start with a number of building cards in their hand; buildings come in five colors, with the purple buildings typically having a special ability and the other colored buildings providing a benefit when you play particular characters. At the start of each round, the player who was king the previous round discards one of the eight character cards at random, chooses one, then passes the cards to the next player, etc. until each player has secretly chosen a character. Each character has a special ability, and the usefulness of any character depends upon your situation, and that of your opponents. The characters then carry out their actions in numerical order: the assassin eliminating another character for the round, the thief stealing all gold from another character, the wizard swapping building cards with another player, the warlord optionally destroys a building in play, and so on.
