# YONQI Dark Stories: Detective

> YONQI Dark Stories: Detective is an AI-powered lateral thinking detective party game for iOS and Android. Solve 200+ mysterious riddles by asking yes-or-no questions, playable solo with an AI assistant or in party mode with friends across 8 languages.

YONQI Dark Stories is inspired by the classic "lateral thinking" / "situation puzzle" / "Black Stories" format, adapted into a modern digital mobile game with AI assistance and voice recognition. Players are presented with a mysterious situation or crime scene and must deduce what happened by asking questions that can only be answered with "Yes", "No", or "Irrelevant".

## Game Modes

- **AI Detective Mode (Solo)**: Play alone anytime. The AI assistant knows the full solution and answers your voice or text questions in real-time. Requires internet connection.
- **Party Mode (Multiplayer)**: Gather 3+ players. One person acts as the Game Master who reads the full secret solution, while other players collaborate as detectives asking questions. Works 100% offline.
