Loup Garou pour une Nuit

One Night Ultimate Werewolf is a social deduction game created by Ted Alspach and Akihisa Okui, published in 2014 by Bezier Games, with a French edition released by Ravensburger from 2016. Each player receives only one role for the whole game, which plays out in about ten minutes with no eliminations and no permanent moderator. The system has since branched into several variants, including One Night Ultimate Vampire and a Harry Potter licensed edition.
