Frequently Asked Questions
Can I play Detective Mystery solo?
Yes. The AI host can run the entire game as a solo mystery experience, playing all suspects and witnesses while you act as the detective.
Is every mystery case different?
Yes. The AI generates a unique case for each session — different victim, suspects, motive, and method every time.
How do I win the Detective Mystery game?
You win by correctly naming the culprit, their motive, and their method. All three must be correct.
Can I ask the AI suspects any question?
Yes. During investigation rounds you can ask any question in natural language. The AI responds in character as each suspect.
How is Detective Mystery different from AI Dungeon?
AI Dungeon is an open-ended solo adventure. Detective Mystery is a structured multiplayer game with a fixed case, real suspects, and a definitive solution — you win by solving it correctly, making it more like a game than a story.
