Room ID format

Room IDs are six characters, alphanumeric, and case-insensitive. They expire when the host quits — they don't persist between sessions.

How to share

Copy the ID from the host's lobby screen and send it to your friends however you like — Discord, Steam chat, carrier pigeon. Friends paste it into Online → Join.

When the ID doesn't work

If the ID won't accept, double-check that you typed it correctly and that the host hasn't closed the lobby. Region mismatch is a separate issue — the game won't warn you.
