Are You the Traitor?is a secret role selection game akin to Werewolf/Mafia. One player is the Evil Wizard, attempting to obtain the Magic Key for nefarious purposes. Another player is the Good Wizard, trying to destroy the Key to keep it out of Evil hands. The other players support Good or Evil in various roles.
Each round, there is a discussion period, after which one of the players acts. After someone acts, the players determine whether the forces of Good or Evil were served, with the prevailing side gaining treasure. Play continues until one player gets enough treasure to win.
