The Werewolf game is conducted solely through discussion and players must exert their cognitive faculties fully in order to win. In the game, players must hide information, in contrast to perfect information games such as chess or Reversi. Each player acquires secret information from other players’ conversations and behavior and acts by hiding information to accomplish their objectives. The game highlights various problems that have not been addressed adequately in the field of artificial intelligence, such as the asymmetric distribution of player information, the use of persuasion for earning confidence, and the use of speculation for detecting fabrications.
