Werewolf is a social game, one where you show up in person. The game is more of a framework for socializing and mingling. You and the other players all take on roles that essentially boil down to being either “Werewolves” or “Villagers”.
In the game, you gather around a long table or sit in a circle and you’re assigned your role randomly. If you’re one of the few werewolves, keep it secret. Claim to be a Villager, because the objective of the game is to have the villagers identify and banish the werewolves from their Village. Your best strategy is to pretend to fit in by claiming to be a villager, too.
By adding additional roles into the game, such as variations of Werewolves and Villagers, the game becomes more complex and more levels of deception are introduced.
