Ultimate Werewolf is an interactive game of deduction for two teams: Villagers and Werewolves. The Villagers don't know who the Werewolves are, and the Werewolves are trying to remain undiscovered while they slowly eliminate the Villagers one at a time. A Moderator (who isn't on a team) runs the game. Ultimate Werewolf takes place over a series of game days and nights. Each day, the players discuss who among them is a Werewolf, and vote out a player. Each night, the Werewolves choose a player to eliminate, while the Seer learns if one player is a Werewolf or not. The game is over when either all the Villagers or all the Werewolves are eliminated.
