- If you your friend is on your friends list on the platform you’re on — like Steam, or a console — your friend’s host game should automatically appear in a menu of active friend games.
- If you aren’t friends on a friends list, you can join anyone with a Join Code. A Join Code is a short, unique code that is generated every time the host starts a session. Your host can then share the code with you so you can join.
(Note that the Mac App Store version of the game does not support Game Center, so you’ll have to use a Join Code.)
