In each round, one player is the ghost who wants to leave valuable items to the new dwellers in the castle. But where? Cards give clues, then the ghost hides the key somewhere in the room, in any place matching the clues. The player who finds it gets a key card. If the ghost makes a mistake, letters are handed out to the "victims" of the round. After 5-8 rounds, the player with most keys and letters is the winner.
