How to Use a Big Walk Join Code

The useful answer

The host must enter the world first, then share the active session code. Other players choose Join Game and enter that code while running a matching game version.

Step by step

Have the host load the save fully.
Open the active session information and copy the code.
Enter it from Join Game.
If it fails, compare the first two version numbers and system clocks.

Why players get stuck here

Codes are session access details, not permanent group identities. Do not leave a live code on a public page longer than necessary.

Verify it before moving on

Before inviting everyone, agree on the host, world size, voice or text preference and the next session time. Those four details prevent most groups from losing progress or creating a world they cannot continue.
