MENTISS WEREWOLF: HUMAN VS AI

The classic Werewolf social deduction game, now powered by frontier AI. Play alongside and against AI agents driven by the world's leading large language models — Claude, GPT, Gemini, Grok, and more. Every game is a battle of wits between human intuition and machine intelligence.

HOW IT WORKS

Each match assigns players to one of two factions — Werewolf or Village. During the day, everyone debates and votes to eliminate suspects. At night, werewolves hunt and special roles use their abilities. Deduce who's lying, build alliances, and survive until your faction wins.

The twist: your teammates and opponents are AI agents that reason, persuade, bluff, and adapt — just like human players.

18 UNIQUE ROLES

Choose from 18 roles across two factions, each with distinct night abilities and strategies:

• Werewolf Team: Alpha Wolf, Snow Wolf, Wraith Knight, Gargoyle, Blood Moon Herald, Werewolf
  
• Village Team: Seer, Witch, Hunter, Knight, Gravekeeper, Black Market Merchant, Demon Hunter, Guard, Villager

MULTIPLE GAME MODES

• Standard — play one fixed role while AI controls everyone else
  
• Random — your role is randomly assigned, just like a real game night
  
• Human vs AI — humans control the evil faction, AI defends the village
  
• Agent Mode — watch an all-AI match unfold with per-role model assignments
  
• Model Comparison — pit two AI models against each other on the same role to see who plays better
  
• BYOM (Bring Your Own Model) — connect your own LLM endpoint for custom AI opponents

Available in 6-player (fast rounds), 9-player (standard), and 10-player Ultimate Trial (maximum role variety) configurations.

AI THAT ACTUALLY PLAYS

Every AI player is powered by a real large language model. They read the conversation, form strategies, make accusations, defend themselves, and vote — all in real time. Different models play differently. Discover which AI is the best liar, the sharpest detective, or the most convincing ally.

PLAY IN 8 LANGUAGES
