The Party Game That Lives in Your Browser

The fastest way to kill a party game is the setup. Someone's phone won't install the app. Someone's laptop needs an update. Fifteen minutes in, half the group is watching one person troubleshoot.

ColdCase Party was built to make that impossible. It's a real-time multiplayer murder mystery that runs entirely in the browser — every player joins by clicking a link. No downloads. No app store. No accounts. If the device has a browser, it can play.

Start a Room — First Case FreeSee the Cases

First case free · No download · Any device · 2–8 players

From zero to playing in under a minute

  1. One person opens coldcaseparty.com and starts a room.
  2. They share the room link or code with the group.
  3. Everyone joins from their own phone, tablet, or laptop.
  4. The case begins — evidence, suspects, and objectives appear for everyone in real time.

That's the whole setup. The game itself handles pacing, evidence releases, and hints, so nobody has to play game master.

A real game, not a gimmick

Browser-based doesn't mean shallow. Each ColdCase Party case is a full investigation: staged evidence drops, suspect interviews, a shared detective board, team chat, puzzles, and a final accusation your group has to commit to. Sessions run 45–60 minutes for 2–8 players, and new cases ship every 6–8 weeks.

Works wherever your people are

Because every player connects in real time through the browser, the same game works for an in-person party, a fully remote hangout, or a mix of both. Couch plus three time zones? Same room, same case, same shared board.

Try it free

Your first case is completely free, with no signup required. After that, the host pays once per session — never per player.
