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. The game takes place over a series of 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.
