About This Game

A fog-bound city in the 1930s. The Town, the Mafia and the Triad hide among the crowd. By day you must talk your way into everyone's trust; by night you can only hope you live to see the morning.

Mafia is an online social deduction game for up to 15 players. Everyone draws a secret role: hunt down the villains, protect your allies, or pursue a goal that is yours alone. Who is lying? Who can you trust? The truth only surfaces through conversation, votes and bodies.

How a day unfolds

  • Discussion: share information, raise suspicions and defend yourself in chat.
  • Vote and trial: whoever gets enough votes takes the stand to make a final defence. Everyone then votes Guilty or Innocent, the scales tip, and the verdict stamp comes down.
  • Execution: the guilty are executed in a dramatic scene and their true role is revealed.
  • Night: investigate, protect, assassinate, kidnap... every role has its own night ability.
  • Dawn: the night's victims are revealed one by one, with their roles and last wills.

Features

  • 57 roles across four factions (Town, Mafia, Triad and Neutral), so no two games play the same.
  • Multiple game modes: Classic, Clue (last wills, private messages and trials), or a fully custom role setup chosen by the host.
  • Death is not the end: the dead gather in the Ghost Tavern to chat with each other, bet on who will die today, and play Russian roulette.
  • Film-noir style: ransom-note collage lettering, an old film-projector opening and finale, and dramatic sound.
  • Post-game story: after every match, the key moments are replayed as a story, and players vote for the match MVP.
  • Available in English, Traditional Chinese and Simplified Chinese.

Please note

An internet connection is required, and the game is played with other real players.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Generative AI tools were used during the development of this game:

Art: role icons, character portraits, backgrounds, and UI paper and texture images were created with AI image tools, then selected, edited and assembled by the developer.
Text and code: UI text, rule descriptions and parts of the code were written with AI assistance and reviewed and edited by the developer.

The game does not generate any content with AI while it runs. Everything players see is made in advance and ships with the game, and player chat is never sent to an AI.
Sound effects and music come from free sound libraries and are not AI-generated.

Name of AI model included with the game: ChatGPT (OpenAI) for images; Claude (Anthropic) for code and text assistance during development.
