If you have seen these murder-mystery evidence boxes and wondered how you actually play one, this is the plain-English version. No jargon. By the end you will know exactly what happens at the table, and you can try one free.

A crime scene report from a case-file murder mystery
It starts with a scene: who died, where, when, and why the case was reopened.

The short version

A case-file murder mystery hands you the same thing a detective gets: a folder of evidence about a death. You read it, you figure out who did it. There is no board to move pieces around, no app telling you what to do, and no host running the night. The documents are the game.

What is actually in the file

  • A crime scene report. The facts: the victim, the location, the time, the official ruling, and why someone reopened the case.
  • Suspect interviews. Each person of interest answers questions. Their words are where the lies live.
  • Evidence. A forensic report, recovered belongings, a photo, a phone record. The detail that cracks it is in here somewhere.
  • A way to check your answer. A good case lets you confirm online or with a sealed solution so nobody spoils it.

How you actually play

  1. Read the scene so everyone knows the basics.
  2. Read the suspects and note who has a motive, who has an alibi, and who says something that does not fit.
  3. Read the evidence and connect it back to the interviews.
  4. Name the killer and check if you were right.

That is the whole loop. It takes anywhere from half an hour for a short case to a full evening for a big one.

How does it compare to Hunt A Killer?

Hunt A Killer is the best-known version of this format, and it works the same way: solve a murder from physical evidence. The differences come down to who makes it, what it costs, and how it ships. We make ours in Canada, by hand, and we let you try a full case for free first.

Why people like it

It is the rare game that is both relaxing and sharp. You are reading and talking and thinking, not racing a timer. It works for one player or a tableful. And the payoff, the moment the pieces click and you name the killer, is genuinely satisfying in a way most games are not.
