Play Werewolf with AI — Watch the Models Battle It Out

Play Online (wolf-cha.com)

Current sponsors:

• ZenMux - Powers the core game flow, roleplay, and summary features with AI models
• Dashscope - Provides additional AI model support
• OpenCreator - Generates AI character portraits

Note: This project was born at the "Watcha + ModelScope Global Hackathon" as an AI-native game.

"Wolfcha" combines Wolf (Werewolf) + Cha (猹, a character from Chinese literature). It's a nod to the hackathon host while also capturing the fun of watching AI characters interact — like spectating a show.

After graduating, getting 8-12 people together for a proper Werewolf game became nearly impossible. While Werewolf is fundamentally a social game, its core appeal — logical deduction, verbal sparring, and reading between the lines — remains captivating even without the social element.

To enjoy Werewolf anytime, anywhere, we built this AI-powered version. As the name suggests, every player except you (Seer, Witch, Hunter, Guard, Werewolves, etc.) is controlled by AI.

Thanks to the growing context windows and instruction-following capabilities of large language models (LLMs), we've implemented a sophisticated dual-layer roleplay system:

• Layer 1: The AI plays a "virtual player" with a unique personality and background.
• Layer 2: This virtual player then takes on a Werewolf role (e.g., Seer) and speaks, bluffs, and reasons based on the game state.

Every conversation is generated in real-time, full of unpredictability and fun.

This isn't just Werewolf — it's a battleground for AI models.

We've integrated multiple top AI models to compete against each other. After each game, you can see which model powered each character. It's a hidden "Turing test" — observe which model reasons sharply, which one seems "adorably clueless," and which one sounds the most human.

Current built-in models (subject to project configuration):

• DeepSeek V3.2
• Qwen3-235B-A22B
• Kimi K2
• Gemini 3 Flash
• Seed 1.8 (ByteDance)

While we don't have a professional art team, we've crafted a polished UI/UX:

• Retro Design Style: Clean layouts with vintage color palettes.
• Dynamic Interactions:
  • Eye-blink transitions for day/night changes.
  • Character lip-sync animations during speech.
  • Unique character portraits for special roles during night actions.

We're continuing to improve:

• Mobile Optimization: Play seamlessly on any device.
• Flexible Player Count: Support 8-12 player custom games.
• Post-Game Review / Chat: Reflect on strategies and memorable moments.
• Special Abilities: Unique mechanics like time rewind and AI insight.
• Custom Model Selection: Choose which AI models join your game.
• Multiplayer Mode: Play with friends alongside AI characters.
• Character Ratings: Upvote standout personalities/models to find the best Werewolf players.

Built with modern web technologies:

• Framework: Next.js 16 (App Router)
• Language: TypeScript
• Styling: Tailwind CSS 4
• UI Components: Radix UI, Lucide React
• State Management: Jotai
• Editor: Tiptap (For rich text interactions)
