WhoDunIt: A Procedural Murder Mystery Generator

View Game Page Play

Brief Description

Every time you run the setup commands, you get a brand-new case.

Welcome to a fully immersive whodunit experience—part sandbox, part solvable case, and entirely procedurally generated. Every game comes pre-built with a murderer, motive, method, timeline, setting, suspects, and a tightly woven web of clues. Your goal: uncover the truth through deduction, not meta-knowledge.

🎲 Step-by-Step Setup:

  1. /Generate Setting — Creates a lavish hotel as the crime scene, with rooms, staff, ambiance, and layout. Written in English.

  2. /Generate # Suspects — Generates your suspects (e.g., /Generate 6 Suspects). The output is in Mandarin Chinese—copy and paste it into {{suspects}} but don’t read it unless you want to spoil the mystery. Only names are readable. To learn about them, you'll have to question them yourself.

  3. /Generate Victim — Reveals who was killed, when, how, by which job title (not name), and generates a massive Mandarin Chinese clue matrix connected to your suspects and setting. Copy and paste into {{victim}}—again, don’t read it unless you want spoilers.

  4. /Help — Use this any time to get small, in-character nudges toward discovering new clues. It won't break immersion or give away secrets.

🔎 Your Role

Choose an investigator persona (or play as yourself). Explore the hotel. Interrogate guests. Cross-reference timelines. Seek inconsistencies. Investigate suspicious items, rooms, and relationships.

All clues are hidden logically and must be earned by your actions. NPCs will lie, deflect, or hide truths. Nobody knows who the killer is—not even them—and some may have good reasons to keep their mouths shut.

This isn’t random chaos: each case has a correct solution. Clues interlink to form a coherent, solvable story. You can absolutely get it right. Or very, very wrong.

♾️ Replay Forever

Every time you run the setup commands, you get a brand-new case. New victim. New killer. New suspects. New lies.

Good luck, detective. The truth is buried under charm, motive, and misdirection.

🔍 Welcome to Murder at the Grand Hotel: A Procedurally Generated Mystery

Someone has been killed. The truth is tangled in polite conversation, half-finished drinks, and deliberately timed glances. The suspects are cultured, charming, and utterly unreliable. And you—whoever you may be—have just arrived.

This is not a board game. There are no cards. Only people. Lies. Motive. Time. And the quiet, unnerving knowledge that the killer walks freely among the living.

🧩 How to Build Your Custom Mystery

Use the following commands to procedurally generate your unique scenario, one layer at a time. After each command, copy the result and paste it into the appropriate variable ({{setting}}, {{suspects}}, {{victim}}). Be sure to set each response to sticky so the AI can reference them during the game.

  • /Generate Setting → Produces a fully described, high-society hotel location in vivid English prose: location, layout, decor, staff, and atmosphere.
  • /Generate # Suspects → Generates a complete cast of guest suspects (in Mandarin Chinese), including personalities, relationships, alibis, and secrets.
  • /Generate Victim → Constructs the crime: the victim, the killer (by job title only), the location, time of death, method, body discovery—and a complex web of discoverable clues (in Mandarin Chinese).
  • /Help → Use this anytime to request a subtle narrative nudge or suggestion of where to go, whom to talk to, or what might warrant a second look.

⚠️ All murder information is encoded in Mandarin Chinese to prevent meta-knowledge. Clues cannot be accessed unless found in-character through logical action or interrogation.

🧠 How to Solve the Case

The game begins once all three elements—{{setting}}, {{suspects}}, and {{victim}}—are generated. You may speak to NPCs, examine rooms, check alibis, interrogate witnesses, and follow leads.

Clues will only emerge if you act in a way that uncovers them: Talk to the concierge. Check Room 417. Revisit the bar after midnight. Read the ledger in the manager’s office. Follow a whisper. Doubt a smile.

Every suspect is hiding something. Only one of them is hiding everything.

📜 Information Control Rules (For Your Protection)
  • No NPC knows who the killer is, not even the killer’s friends—or the killer themselves, until the murder is committed.
  • Clues are contextual: they are only revealed when the player fulfills a specific discovery condition.
  • NPCs may lie. Frequently. Even witnesses distort truth for self-preservation.
  • Narrative distance is enforced: characters only know what they’ve seen, heard, or been told.
  • The murderer will defend themselves: with logic, deceit, or charm—and every reason to believe they are innocent.
🛎️ Final Note

The Grand Hotel is opulent. Elegant. A place of piano lounges, bellboys, and champagne over ice. But underneath the marble floor and velvet carpet, something has gone terribly wrong. A murder has happened. A killer walks free. And you are the only one asking the right questions.

The mystery begins when you are ready. Start with: /Generate Setting then /Generate # Suspects (you pick how many) then after both of those are done and pasted, /Generate Victim Once you're ready to begin, type /START GAME.
