(adsbygoogle = window.adsbygoogle || []).push({}); This beta was not meant for public release.

YOU CANNOT PLAY GAMES on the Beta if you are not invited to participate. Even if you aren't it is possible to look around and seeing as it's not a pain to download and will minimize further downloading when the full version is released i'd say it's worth it.
