# Turtle Noir > AI-hosted murder mystery game with lateral thinking puzzles, situation riddles, and yes/no mystery cases. Turtle Noir is a free online mystery game where an AI host runs lateral thinking puzzles, situation riddles, and yes/no mystery cases. Players solve mysteries by asking yes/no questions to uncover the hidden truth behind each story. ## Key Features - **AI Game Master**: AI characters host and judge each mystery in real time — no human moderator needed. - **Multiplayer Party Mode**: Create a room and share the link — up to 10 friends can join instantly from any browser. - **Solo Play**: Play alone against the AI at your own pace. - **Mystery Puzzle Library**: A curated library of AI-hosted mystery riddles, situation puzzles, and lateral thinking cases. - **Free to Play**: No downloads, no sign-ups required to start playing. - **Mobile-Friendly**: Fully optimized for phones, tablets, and desktops. ## How It Works 1. Pick a mystery puzzle from the library (or get a random one). 2. Read the "surface story" — a short, mysterious scenario. 3. Ask the AI host yes/no questions to deduce what really happened. 4. Piece together the clues and submit your answer when ready. ## Links - [Homepage](https://turtlenoir.com/) - [What is Turtle Soup?
