🔑 Room codes

The room code explained

The room code is the connective tissue of your party night — it's how a group of friends lands in the same lobby instead of a random public one. Here's exactly how it works, how to share it, and what to do when it won't let someone in.

What a room code is

When someone hosts a private room, the game generates a short code — a string of characters — that uniquely identifies that lobby. Anyone who enters the code joins that specific room. It's the difference between "play with my friends" and "play with strangers." For a party night, you always want a private room with a code.

In one line

Host creates private room → gets code → shares code in group chat → friends type it in → everyone's in the same lobby.

How to create a private room

  • 1. Pick a host. One person runs the lobby — ideally someone with a stable connection.
  • 2. Launch the game on Steam.
  • 3. Choose host / create a private room (not public matchmaking).
  • 4. Grab the code the game shows you.
  • 5. Share it in your group chat or Discord.

How friends join

Each friend launches their own copy of the game, picks join a room, and types the code. They should appear in your lobby within seconds. Wait for the whole group before starting — once a round is underway, late joiners usually have to wait it out.

tip →

If everyone's added each other on Steam, you can sometimes invite directly through Steam friends instead of typing a code — faster, no typos.

When a code won't work

  • Typo. The most common cause. Re-read the code character by character; O vs 0, I vs 1, etc.
  • Room already started. If the host kicked off a round, the lobby may not accept joins mid-round. Wait for the round to end, then have them rejoin.
  • Room closed / host left. The code dies when the host closes the room or quits. Get a fresh code.
  • Version mismatch. If some players haven't updated the game on Steam, the join can fail silently. Make everyone verify their game is up to date.
  • Wrong region / lobby type. Make sure everyone's selecting the same room type (private) the host created.
