Mafia , also known as  Werewolf , is a party game created by Dmitry Davidoff in 1986 modelling a conflict between two groups: an informed minority (the mafia), 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: one, during which the mafia may covertly "murder" an innocent, and two, in which surviving players debate the identities of the mafia and vote to eliminate a suspect. The game continues until all of the mafia have been eliminated or until the mafia outnumbers the innocents.
