Troubleshooting Numberblocks Generator Not Loading

A blank frame does not always mean the project is dead. Sometimes the runtime is still loading, and sometimes the iframe host is just taking its time.

My rule is: wait a bit, refresh once, then stop hammering refresh. If it is still blank, I open the site player in a new tab because that removes some of the page-frame weirdness.

Privacy extensions and school filters can block the embedded player while the rest of the page looks fine. That is annoying because it makes the site look broken even when the issue is outside the article page.

If I suspect that, I try a cleaner browser profile or a different network. On a managed school device, the filter may simply be the answer.

Phones are not always kind to Scratch-style stages. If the controls feel tiny, I rotate the phone and close extra tabs before judging the page.

For heavier pages, especially Websim, I would rather move to a tablet or laptop. It is more fun than pretending a cramped phone screen is good enough.

Some browsers want a real tap or click before they allow fullscreen. I click inside the stage first, then hit the fullscreen or open-player button again.

On iOS, fullscreen can still be limited. In that case I usually use the site player route because it gives the game more of the screen without relying on perfect fullscreen support.

If there is no sound, I tap inside the project before changing anything else. Browser audio rules are weird, and a real click or tap often wakes things up.

Then I check the obvious stuff: muted tab, silent mode, device volume. If all of that looks right, I refresh after tapping once and try again.
