A Big Walk join code is a short session code created when the host starts a world. The host finds it in the host menu before play or in Session Details after starting; invited players enter that current code to join the active session.

What Are Join Codes in Big Walk?
What to know
Join codes are private access codes for one active Big Walk session. They are not reward codes, redeem codes, permanent invitations, or a way to transfer a save. A new join code is created each time the host starts a session, so an old code from a previous night will not open the host’s current world.
Anyone who knows the current join code may be able to enter the session. The official FAQ recommends using a password when the host needs to control access, and keeping both the code and password out of streams, public posts, and screenshots.
02 · Steps
How to Find & Share Your Join Code
What to know
The host can read the join code in the corner of the host menu before starting the game. Once the session is running, the host opens the in-game menu and chooses Session Details to find the same session code again. Share it directly with the invited group rather than posting it publicly.
Steam players may also see an active friend’s world through the platform friends list. On PS5 and Nintendo Switch 2, use the normal platform-friend flow when it is available, or use a join code. Mac App Store players must use a join code because that version does not support Game Center friend-session discovery. Big Walk is not officially available on Epic, so there is no Epic-specific join-code route to publish.
- Choose the player who owns the returning save as host
- Start or load that world
- Before play, read the join code in the host-menu corner
- After play starts, open Session Details to find it again
- Send the current code privately to the invited players

How to Join a Friend's Game
What to know
First wait for the host character to finish loading into the world. Then use the supported friend-game menu when the host appears there, or enter the host’s current join code. A code entered before the host has a live session cannot make a world available.
[Screenshot placeholder: host menu showing the Join Code, followed by the guest join screen.] Use a fresh code only after the host has confirmed that the correct saved world is running. This avoids confusing a session code with a reward code or an older invitation.
- Ask the host to load fully into the world
- Confirm the host shared the current join code
- Open the supported join or friend-game flow
- Enter the code exactly as shared
- If joining fails, compare the first two version-number sections before retrying
04 · Steps
Fix 'Invalid Code' Error
What to know
An invalid-code message usually means the code was copied from an earlier session, entered incorrectly, or requested before the host created the active world. Ask the host to open Session Details and send the code again instead of guessing at characters.
- Have the host confirm the world is active
- Open Session Details and copy the current code again
- Check for mistyped characters or spaces
- Enter the new code once through the supported join flow
05 · Steps
Fix 'Session Unavailable' Error
What to know
A session unavailable message does not prove that a code is bad. Confirm the host is still in the world, has no connection warning, and has not ended or restarted the session. Then check that the guest and host have compatible versions before requesting a fresh code.
- Confirm the host is still loaded into the world
- Check the host for a connection warning
- Compare the first two version-number sections
- Ask for a new code only after those checks
06 · Steps
Fix 'Cannot Join' Error
What to know
When the code is current but a guest still cannot join, use the connection checklist rather than changing saves, files, firewall rules, or security settings. The official sequence is to check the host, both internet connections, system clocks, compatible versions, and a full game restart.
- Confirm the host is fully loaded
- Check both internet connections and system clocks
- Restart Big Walk completely for host and guest
- Retry with the host’s current join code

Crossplay & Join Codes
What to know
Join codes work for supported crossplay groups: Windows, Mac, PlayStation 5, and Nintendo Switch 2. The host still owns the save, and every player needs a compatible game version. Crossplay does not add split screen, public matchmaking, or support for a platform outside the official list.
If your group is in one home, each player still needs a supported device, display, copy, and account. Use the multiplayer guide for the split-screen and local-co-op boundary before planning the session.
What this guide does not claim
Community labels are not presented as official names. Approximate coordinates stay marked as approximate, version-sensitive facts need a publication-day check, and no unsupported platform, code, solo route or mod-only shortcut is invented.

Frequently asked questions
Are Big Walk join codes permanent?
No. A join code is generated for the host’s active session and changes when a later session begins.
Can I use a join code for crossplay?
Yes, across the officially supported Windows, Mac, PS5, and Nintendo Switch 2 versions when the group has compatible versions.

A Big Walk join code is a short session code created when the host starts a world. The host finds it in the host menu before play or in Session Details after starting; invited players enter that current code to join the active session.
How current is this information?
The source pack was reviewed on August 17, 2026. Platform status, prices, versions and live service information must be checked again on the publication date.
Are community puzzle names official?
Not necessarily. Big Walk does not provide an official name for every challenge, so this site identifies player-made labels whenever that distinction matters.
