Troubleshooting board

Game not loading

Refresh, try fullscreen, or check if the school network blocks embeds.

Fullscreen issues

Use the dedicated /play/ route if the browser blocks iframe fullscreen.

No sound

Tap inside the game once; mobile browsers often lock sound first.

Mobile lag

Close extra tabs and use the lighter Main or Scratch version.
