How it works

  1. 01

    Choose the mood

    Pick a theme, the occasion and whether you want it cosy and funny or properly dark.

  2. 02

    Get the premise

    A title, a setting, a victim and the question the whole table will be trying to answer.

  3. 03

    Make it a full mystery

    Save your plan and Murder At Mine can create the full mystery for your group, with a character for every guest.

What makes a good murder mystery idea

  • A setting guests can dress for without buying much
  • A victim almost everyone had a reason to dislike
  • One clear question, so the table knows what it's solving
  • Suspects with motives that pull in different directions
  • A tone that suits your group: funny, glamorous or spooky

From an idea to a murder mystery you can host

An idea is the easy part. The hard part is giving every guest a character with secrets, lies and something to do all night, then making sure the clues point to one answer. Murder At Mine does that part: it builds a full case for your exact guest list, runs three staged scenes on everyone's phones and saves the reveal for the end.

Interrogation notes

Frequently asked questions

Is the idea generator free?

Yes. Try as many themes and vibes as you like.

Can I use the idea without the app?

Of course. Use it as a starting point for your own mystery. If you want the characters, secrets and scenes written for you, save it and host it with Murder At Mine.

How many players do I need?

Murder At Mine mysteries are for 4 to 10 players, and the host can play too.

Will the app use the same idea?

Yes. A saved idea becomes the starting point for your mystery in the app, so the title, setting and premise carry through, with a character written for each of your guests.
