its usually a card game. look up ultimate werewolf on google. you can get the rules there. A brief explanation is that the werewolves are trying to kill off the villagers and the villagers are trying to figure out who the werewolves are so they can kill them. the game has two phases; night phase were the werewolves select someone to kill and the day phase were the villagers try to figure out who to string up. its a fun game of lies.
