Troubleshooting
Common Issues
Numberblocks Generator not loading
Refresh once, then switch versions or open the fullscreen player. If a third-party host is blocked, the local player page is usually the fastest fallback.
iframe blocked
School networks, privacy extensions, and browser settings can block third-party players. Open the site player or fullscreen player in a new tab.
mobile lag
Rotate to landscape, close heavy tabs, use the site player, or switch to the main generator if the Websim player feels slow.
fullscreen not working
Tap the player first, then press Open Fullscreen again. On iOS, open the dedicated player page for more room.
sound issues
Tap inside the game stage, check the browser tab is not muted, and turn off silent mode before restarting the version.
