One-Night Werewolf Rules
In One-Night Werewolf, the Villagers must try to vote out Werewolves, while the Werewolves have to stay alive. All players act as a special role with a special ability.
At the beginning of the game, the "announcer" chooses and shuffles 3 more (possibly repeated) roles than the number of players. Each player receives card, and the remaining cards are put in the middle. The "announcer" follows a script to ask certain roles to wake up, do an action, and go back to sleep.
Once the night is over, all players discuss with each other who to kill, and then vote. Depending on who was killed, a certain team wins.
