Mafia Deck Online

About the game
An online social deduction card game for up to 12 players. Take a secret role — Civilian, Mafia, Doctor, or Commissioner — debate with accusation, defense, and analysis cards, then vote to unmask the killers.
Original Steam description
Everyone at the table has a secret. Can you spot the lie?
Mafia Deck Online brings the classic social deduction party game online as a fast, card-driven showdown. Up to 12 players take seats around the table and are secretly dealt a role — Civilian, Mafia, Doctor, or Commissioner. Survive the day through debate and votes, then endure the night while the Mafia strikes in the dark.
How a Round Works
Role Reveal — You're dealt a hidden role. Civilians hunt the Mafia, the Mafia kills by night, the Doctor protects one player, and the Commissioner secretly checks identities.
Discussion — Speak through your hand. Play Accusation, Defense, and Analysis cards as speech bubbles to point fingers, plead innocence, or call out suspicious behavior.
Voting — The table votes, and the player with the most votes is eliminated.
Night — The Mafia picks a victim, the Doctor chooses someone to save, and the Commissioner investigates. Dawn breaks, and the next round begins.
