Big Walk Join Code Not Working: Session and Crossplay Checks
Use a valid Big Walk Join Code across PC, Mac, PS5 and Switch 2.
Direct answer
A Join Code is short-lived and generated each time the host starts a session. Ask the host for the current code, enter it exactly, and confirm the host has not closed or restarted the session. Same-platform friends may be able to join through the friends' games menu instead.
Do these in order
Shortest reliable path
Replace old codes
Codes are generated each time the host starts a session. A screenshot or message from a previous session may no longer apply.
Confirm the host is in-game
The host must start first and remain active while others connect.
Enter the code exactly
Avoid extra spaces and verify each character with the host.
Check updates on both systems
Install the newest build offered on each platform before retrying crossplay.
Use friends' games when available
If you are friends on the current platform, the host's game can appear automatically in the friends menu.
Rotate the code once
The host can restart the session and share the new code. Repeated restarts without collecting the error add little evidence.
