How to Play an AI Detective Puzzle Game
An AI detective puzzle puts you in the detective's chair. There's a body, a handful of suspects, and a web of lies — and it's your job to pull the truth out of it through logic, evidence, and careful questioning. Unlike a board game with scripted lines, every suspect here is played by an AI you can question freely. This guide walks you through everything you need to crack your first case.
1. Choose a case
Start by picking a mystery that grabs you — a fog-bound manor, an isolated mountain village, or a house that hides more rooms than its floor plan admits. Each case has its own atmosphere, cast, and central puzzle. Beginners can start anywhere; there's no wrong order.
2. Read the briefing
Every case opens with a case briefing: who died, when, where, and the strange details that don't add up. Read it carefully. The contradictions in the briefing — a stopped watch, a missing square footage, a cup of water no one should have drunk — are your first leads.
3. Interrogate the suspects
This is the heart of the game. Type questions in your own words, just as you'd speak to a real witness. Ask where they were, who they argued with, what they saw. The AI suspects stay in character: some lie, some deflect, some let slip more than they intend. Press on inconsistencies — a story that changes is a story worth chasing.
4. Search the crime scenes
Move through the rooms and search them for physical evidence. Bedrooms, studies, corridors, greenhouses — each location hides objects, marks, and documents that corroborate or contradict what the suspects told you. Evidence beats testimony, so let what you find guide your next round of questions.
5. Track your clues
As you investigate, clues are collected for you. Review them often. The solution is rarely one big reveal; it's a chain of small facts that only point one way once you line them up — means, opportunity, and a motive strong enough to kill for.
6. Make your accusation
When the pieces fit, name the killer. A strong solution doesn't just say who — it explains how the murder was done, why, the killer's state of mind, and why the obvious suspects (the red herrings) are innocent. Get all of it right and the case is closed.
Tips for new detectives
- Ask open questions first ("What did you see tonight?") before narrowing in on specifics.
- When two suspects' stories conflict, that gap is usually where the truth hides.
- Re-search a room after a confession — new information makes old evidence mean something new.
- Don't trust the first confession; the most suspicious person is often a red herring.
