"마피아" is a popular social deduction game that involves players taking on different roles within a fictional community. The game typically includes two main groups: the 마피아, who secretly work to eliminate other players, and the 시민, who aim to identify and vote out the 마피아. Players discuss, debate, and strategize during each round, trying to uncover the hidden identities of their opponents. The game can accommodate various numbers of players and often includes additional roles, such as the 의사 (doctor) or 경찰 (cop), which add complexity and intrigue. Each game session usually consists of alternating night and day phases, where players make decisions that impact the outcome of the game.
