YONQI: Dark Stories Mystery

Murder mysteries, crime riddles and dark stories

YONQI turns strange cases into interactive yes-or-no detective games. Read a mysterious situation, ask smart questions, follow the clues and reconstruct what really happened. Solve more than 200 stories alone with AI or bring everyone together for a murder mystery party.

Two Ways to Play

AI Detective Mode — Play Solo
Investigate whenever you want, without a host. Ask questions by voice or text and receive instant answers from your AI detective companion. Test a theory, eliminate false leads, uncover the motive and solve each case at your own pace.

Party Mode — Play with Friends
Turn a house party, family game night, road trip or college hangout into a social mystery game. One player becomes the Game Master and secretly reads the solution. Everyone else asks questions that can be answered with “yes” or “no” until the group explains the entire story.

How Party Mode Works
• Gather your friends or family around one phone
• Choose a crime, horror or mystery story
• The Game Master reads the hidden solution
• Detectives ask strategic yes-or-no questions
• Follow the evidence and challenge every assumption
• Solve who did it, how it happened and why

No cards, board or lengthy setup are needed. Pick a case and begin the investigation in seconds.

More Than 200 Mystery Stories
Explore a growing collection of short, replayable cases across multiple categories:
• Murder mysteries, suspects, motives and alibis
• Crime scenes and detective investigations
• Dark Stories with shocking plot twists
• Horror, thriller and paranormal events
• Lateral-thinking puzzles and situational riddles
• Logic challenges, brain teasers and deduction games
• Spy missions, imposters and hidden identities
• Noir mysteries, lies and false evidence
• Ghost stories and unexplained events

Yes-or-No Riddles and Lateral Thinking
The answer is rarely obvious. Each situational puzzle hides an unexpected explanation. Ask whether a detail matters, connect clues that seem unrelated and look at the case from another angle. The better your questions, the faster you reach the truth.

Voice-First Investigation
Speak naturally instead of stopping to type. Voice recognition keeps the interrogation moving during solo and group play, while text input remains available whenever you prefer it.

An Intelligent AI Detective Companion
The AI considers the context of each mystery and responds to your investigation:
• “Yes” — your theory is moving in the right direction
• “No” — eliminate that lead and try another angle

Use precise questions to narrow the possibilities, identify contradictions and crack the case.

Built for Mystery and Puzzle Fans
YONQI combines the tension of a murder mystery with the simplicity of a guessing game. It is made for players who enjoy detective stories, crime riddles, brain games, Black Stories, social deduction and classic whodunits. Instead of guessing a single word, your group reconstructs a complete chain of events.

A Social Game That Starts Conversations
