Case Mind: Detective Mystery

Sixteen separate murder files. Each one is a full story: a victim, a circle of suspects, a motive, physical evidence, contradictions, and a fair final deduction.

Case Mind is an interactive detective game where AI suspects answer the questions you type yourself. Ask about alibis, press a contradiction, calm a nervous witness, or confront someone with a clue you found. There are no fixed dialogue trees; the interrogation follows you.

A FAIR MYSTERY, NOT A RANDOM CHAT
The AI does not choose the killer while you play. Every culprit, timeline, clue and solution is authored in advance. The AI gives each suspect a voice; the case engine protects what really happened.

WHAT YOU WILL DO
- Interrogate suspects in natural language
- Search the board for evidence and hidden leads
- Rebuild the timeline of the crime
- Track stress, trust, lies and contradictions
- Accuse with culprit, method, motive and proof

SIXTEEN STORIES TO SOLVE
From locked rooms and country houses to theatres, trains, factories and poisonings, every case has its own cast and logic chain. Clues matter: miss one and the picture stays incomplete; connect them and one answer remains.

FOUR WAYS EVERY CASE CAN END
Naming the killer is not the end of it. Every case has four different endings, and which one you get depends on what you proved, who trusted you, and what you left buried. Close the same file twice and it can finish differently. Your casebook keeps a record of which endings you have unsealed.

SOLO OR CO-OP
Play alone, or invite another detective into the same investigation. You share suspects, evidence, notes and timeline without waiting for each other. Only the inviting detective needs Premium; the invited partner joins that shared case free.

FREE TO START, FAIR TO FINISH
Cases open through play, not through a paywall. Premium removes ads and adds 5 hints each month, but the case stories themselves stay playable for everyone.

Available in English, Turkish, German, Spanish, French, Italian, Korean, Arabic, Chinese and Hindi.
