This document provides the rules for playing the Mafia party game. It explains that players are each dealt a card assigning them a secret role of Mafia, Doctor, Cop or Townsperson. At night, the Mafia chooses someone to eliminate, Doctors choose someone to save, and Cops guess the Mafia members. In the day, survivors discuss accusations until one player is voted out, with the Mafia or Townspeople winning depending on role percentages. The game proceeds in rounds of night actions followed by daytime discussions and votes until only one side remains.
