Take a seat at the table. Someone here is mafia — discuss with cards, watch the suspects, and vote them out before the night falls.
Mafia Deck Online is an online social deduction game for 6–12 players. Classic mafia rules rebuilt as a card game: hidden roles, structured discussion cards instead of open chat, a day & night cycle, and a vote that decides who leaves the table. Play with friends in a private room, join matchmaking, or fill the table with bots and play solo. How it compares to other deduction games → games like Among Us, Town of Salem and Project Winter · the rise of online social deduction games.
Every player gets a secret role: Mafia, Doctor, Commissioner, or Civilian. The mafia knows each other — nobody else does.
No free chat, no shouting. Speak with discussion cards: accuse, defend yourself, or call out suspicious behavior — all in preset phrases anyone can understand.
Days are for spotlight speeches and voting. At night the lights go down and special roles act in secret — the mafia strikes, the doctor saves, the commissioner investigates.
Host a private room or jump into matchmaking. Empty seats are filled by bots, so you can even play a full game alone.
Your role is revealed to you alone. Mafia players learn who their partners are.
Each player gets a spotlight turn. Play cards to accuse, defend, or analyze.
Vote a suspect out of the game. A tie means nobody leaves.
Mafia pick a victim, the doctor protects, the commissioner checks a role.
Civilians win by eliminating all mafia. Mafia wins by taking over the table.
