Werewolves

Werewolf, is a party game created by Dmitry Davidoff in 1986 modelling a conflict between an informed minority and an uninformed majority, the innocents. At the start of the game, each player is secretly assigned a role affiliated with one of these teams. The game has two alternating phases: night, during which the werevolves may covertly "murder" an innocent, and day, in which surviving players debate the identities of the werevolves and vote to eliminate a suspect. Play continues until all of the werevolves have been eliminated or until the werevolves outnumbers the innocents.
