More about this game
Step into the shoes of a detective to solve a chain of five interconnected locked-room mysteries. Your goal is to examine crime scenes, gather documents, and build a flawless police report. The core loop involves scanning rooms for hidden traces, filing evidence, and confronting three witnesses per chapter to expose their lies. Difficulty increases as you must solve mechanical puzzles and decode ciphers to unlock new clues. A run ends when you successfully prove the culprit, method, and motive with two exact pieces of supporting evidence each.
Tips
- The magnifier takes time to focus. Hold it steady over a suspected trace for about a second until the marker appears, then inspect it.
- Every claim in your final report requires exactly two distinct supporting exhibits. If your case is rejected, review the timeline and motive connections.
- For the route puzzle in the second chapter, you must tap the four locations in the exact order shown by the wet trolley tracks.
FAQ
- Why was my accusation rejected?
- The prosecutor will reject your case if your hypotheses, evidence, and connections do not perfectly align. Ensure you have two direct exhibits for the culprit, method, and motive, and complete any scene puzzles first.
- How do I challenge a witness?
- Open the witness tab, read their statement, and tap the challenge button. You must select a specific piece of filed evidence that directly contradicts their story to force a new reply.
- How do I solve the cabinet code?
- Read the cabinet code rule and the shift slip evidence carefully. You need to enter the four digits of the final locking time in hours and minutes, ignoring the colon.
