About This Game

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 6 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.

Key Features

  • Online rooms for up to 6 players — bots can fill empty seats
  • Card-driven debate: accuse, defend, and analyze instead of free chat
  • Timed day/night phases keep matches quick and tense
  • Customize your character's look, clothes, and color
  • AFK protection keeps games moving
