Players Can't Join

"Game not found" (J201)

Cause: The session code on their phone doesn't match a live session.

Fix: Check the code on the audience screen. Make sure they're entering the 6-character game code, not the join URL. Codes are case-insensitive but must be exact.

If you've ended and started a new game, players who joined the old one need to re-scan the new QR code.

"Incorrect PIN" (J101 / S301)

Cause: You set a PIN on the session and the player typed it wrong.

Fix: Read out the 4-digit PIN from your host page. Or remove the PIN from the session settings if you don't need it.

"No internet" (J501) or join page never loads

Cause: The player's phone has no signal or is blocked from the site.

Fix:

- Ask them to switch to mobile data instead of the venue Wi-Fi (most common fix)
- Or, ask them to disconnect and reconnect to the venue Wi-Fi
- Test the join URL on your own phone via mobile data to confirm the site is reachable

If many players hit this, your venue's Wi-Fi may be blocking outbound traffic. See the Wi-Fi troubleshooting guide.

QR code won't scan

Cause: Light reflection on the screen, dirty camera lens, or QR too small.

Fix:

- Tap the QR overlay button to enlarge it on the audience screen
- Move the player closer to the screen
- Reduce reflection (close blinds, change projector angle)
- Ask them to type the join URL manually instead: letsgogames.co.uk/join with the code

"Game full" (J301)

Cause: Game has hit its player capacity.

Fix: Increase the player limit in session settings on the host page. Or end the session and start a fresh one with a higher cap.

"Join timeout" (J401) or "Rate limited" (J601)

Cause: Server slow to respond, or too many join attempts in a short time.

Fix: Wait 60 seconds, then ask the player to refresh and try again. If timeouts keep happening across players, check our status page.
