disabled_by_defaultWe are aware of an issue with the sticky ad at the bottom of the page sometimes not loading correctly and becoming un-closable. This is not intended behavior and is meant to auto-close when zooming as well. We're working on resolving this with our provider but in the meantime, refreshing often fixes it. Sorry for any inconvenience.
edit: they do have it! it isnt marked as a clone or bootleg of space invaders though, meaning its confirmed as a real arcade game!
