One Night Werewolf is a board game released in 2012 for 3–7 players, 10 minutes per game, and ages 10 and up. It was designed by Akihisa Okui and its main mechanics are Variable Player Powers, Team-Based Game, and Hidden Roles.
In One Night Werewolf, a simplified version of Werewolf, there is a single night phase and a single day phase. As in werewolf, players are dealt roles which are kept hidden for the duration of the game. During the night phase, players who have the Sorcerer, the Werewolves, and the Phantom Thief each wake up and perform their special action for 10 seconds. During the day phase, players discuss who the werewolves are (or if there even are werewolves). Then all players vote simultaneously for a player. The player with the most votes is killed. If at least one werewolf is killed, the Human team wins. If no werewolf is killed, the Werewolf team wins.
One Night Werewolf supports 3–7 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for One Night Werewolf is 10 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists One Night Werewolf for ages 10 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
One Night Werewolf has a complexity rating of 1.2 out of 5 from BoardGameGeek players, which makes it a light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
