What the code does
A Join Code gives a player a direct route into the host’s current session when the platform friend list is not enough. The official FAQ describes it as a code generated each time the host starts a world. That makes it useful for a known group, not a permanent identifier that can be reused for every future walk.
What the host should do
The host starts or opens the session, checks the session details and copies the current code. Share the code only with the intended players, then keep the session open while they complete the join flow. If the host starts another session, ask for the new code instead of assuming the previous one remains valid.
What the joining player should do
Open the game’s join route, enter the code exactly as provided and wait for the session to resolve. Avoid adding punctuation, spaces or explanatory text when copying the code. The collected sources confirm the host and session logic, while exact button labels can vary by platform and should be checked in the live UI.
Friend list versus Join Code
Use the platform friend route first when the friend is already visible there. The host can use a Join Code when the relationship is not exposed automatically or the group crosses platform boundaries. These are two entry paths for a known group, not separate matchmaking modes.
Crossplay context
Big Walk supports cross-platform play across its currently listed versions, so a Join Code can be relevant to a mixed-platform group. The code does not add an unsupported platform to the list and does not turn Xbox into a current version. If the platform itself is not listed, resolve that question before debugging the code.
Common failure checks
Confirm that the host is still in the session, that the code is from the current session details and that every player is using a supported platform. Re-copy the code if one character may have been lost, and verify that the host did not create a new world after sending it. Without a field-tested error table, exact failure messages remain待实测.
Protect the group and the save
A Join Code should be shared with the people who are meant to enter the session, not posted as an open public room password. The host also owns the save, so joining the right session matters for continuing progress. Read the save-progress page before handing the code to a different host or planning a long-running group.
