One Night Ultimate Werewolf crams all the suspicion and drama of a full social deduction game into a single round. Everyone secretly receives a role — one of the dastardly Werewolves, the helpful Seer, the tricky Troublemaker, or one of a dozen other characters, each with a special ability — then, over one frantic morning, the village debates, bluffs and votes, because lynching just one werewolf is enough to win.
Designed for 3–10 players, each game lasts about 10 minutes, making it a light, endlessly replayable party game recommended for ages 8 and up. Notable mechanics include hidden roles, bluffing, deduction, voting and variable player powers.
Released by Bézier Games in 2014, it is a condensed version of the party game Ultimate Werewolf. Unlike the original, it needs no moderator, has no player elimination, and finishes in minutes. It can also be combined with other titles in the One Night series for epic battles.
