Voiced mysteries for game night.

A murder at a snowed-in hotel. A break-in at a company that should have seen it coming. Open a case on your TV, gather two to eight friends, and crack it in about ninety minutes.

  • Nothing to print
  • Nobody has to host or act
  • Every character is voiced
  • Plays in your browser

Ready in two minutes

Three steps, and the night starts.

  1. Open it on one screen

    A TV, a laptop or a monitor everyone can see. Paste your key once and the case opens in the browser.

  2. Gather your detectives

    Two to eight players work as one team. Nobody gets a role to memorize, and nobody has to run the game.

  3. Solve it together

    Read the evidence, question voiced suspects, crack the locks, then make your case and get scored on it.

Why no prep

Everything a party kit asks of the host, the game does instead.

Printable murder mystery kits are great for big costume parties. They also mean printing, cutting, handing out roles and someone reading the script. Ours is built for the nights you'd rather just play.

A note from the case room

We're a small studio that makes one kind of thing: mysteries a group can solve together on one screen. Every clue you need is in front of you, every suspect has something to hide, and the ending holds up when you go back and check.

We'd rather make a few cases well than a lot of them fast. How we make them →
