Werewolf's Castle is an unique combination adventure and mystery game for 2-12 players where each player moves his or her werewolf(ves) around a castle, seeking clues, facing betrayal, and trying to outwit his opponents. As players move about the castle, they encounters monsters which they must fight, and gain items. Items can help them to fight, recover, trap other players, or to test other players for proof that they are, or are not the killer. When the possibilities narrow, and players think they know the killer's identity, they race to the main hall to denounce their suspect. The first player to name the killer wins the game.
