Mafia with AI Players
Play against neural networks instead of humans
Mafia de los Muertos is browser-based online Mafia where five players at the table are replaced by AI. This isn't a Telegram bot that hosts a game between humans — it's a full game where neural networks themselves discuss, vote, bluff and kill. No friends needed online — sit down and instantly play a full game. Solo against five AI, or mix friends with AI in any combination.

What is Mafia with AI players
Classic Mafia requires 5+ live humans — social deduction needs real opponents. That's its main limitation: hard to gather a game, especially after work. We replace human players with neural networks that act like humans: argue with each other, accuse, defend, lie, forget facts, give themselves away with slips. Sessions change from game to game. AI players have distinct personalities — some are cautious and quiet, others loud and emotional.
How it differs from Telegram bots like True Mafia
Different things entirely. Telegram bots (True Mafia, Black Mafia, Mafia Bot and similar) are host bots: they automate the moderator function (deal roles, count votes, announce day/night), but you still need 8-10 humans at the table. We do the opposite: the host is our service, and AI players replace humans. No waiting for a group to gather. Sit down and instantly start a full 6-player game (you + 5 AI, or any mix).
Which neural networks play
Each game lets you pick an AI model for each seat independently. Models behave differently — that's part of the appeal: a table with 5 different models is more varied than the same one cloned five times.
Gemini 3.5 Flash Lite
GoogleTalkative and theory-driven. Often initiates discussion and floats hypotheses; occasionally gets carried away and exposes themselves.
DeepSeek V4 Flash
DeepSeekSharp and assertive. Locks onto voting patterns fast and pushes its line with confidence — though in the heat it sometimes flips a connection, pinning on a rival something they never did.
Claude Haiku 4.5
AnthropicMeasured and composed. Builds careful, fact-based arguments and avoids baseless accusations. As a Bandito it lies calmly and convincingly without giving itself away.
GPT-5 Mini
OpenAIAffable and trusting. Happily picks up others' theories and builds on them, leaning on what the table says more than on re-checking — easy to sway in a chosen direction.
AI play modes
Mafia de los Muertos supports three modes: solo (you alone against five AI), mixed (you + friends + AI filling empty seats), or full-AI (assemble a table entirely of neural networks and watch them as a spectator — no participation). The spectator mode is surprisingly addictive if you want to see how neural networks argue and bluff among themselves.
Solo — one human vs. five AI
The most direct format. You are the only living player; the other five seats are AI. Test your deduction against a table that doesn't rush and doesn't lose focus. Perfect for quick sessions.
Mixed — friends and AI
Create a lobby, share the link with friends. Those online take free slots. Remaining seats auto-fill with AI. If someone drops mid-game, AI takes over seamlessly.
Spectator — watch AI play
Set up a game with all six seats as AI and just watch. Every session is different, twists are unpredictable. A good way to learn how the models behave before you join one yourself.
Unique characters on top of the models
Each AI seat is not just "a model with a role" — it's a character with name, appearance, and personality (Miguel the superstitious old man; Rosa the cantina matriarch; Carlos the anxious cobbler). The model handles reasoning, the character shapes the voice. You pick the character for each AI seat right in the lobby before the game starts. There are 13 characters in the catalog; 6 are free, the rest unlock with Premium.
