Microsoft's game streaming service Project xCloud is live, and those who registered for the Preview should now be playing Xbox games on Android devices. That's assuming they're lucky, of course.

When Microsoft opened registrations for the Project xCloud Preview it also warned gamers there would only be a limited number of spots and a lot of interest. Registering was no guarantee of getting one of those spots, with invites potentially not going out for "several months" such was the anticipated demand.

Proud of the #ProjectxCloud team for launching the public preview – it's an exciting time at Xbox. Invitations are rolling out now and will continue over the coming weeks. We're excited for all of you to help shape the future of game streaming. — Phil Spencer (@XboxP3) October 14, 2019

The preview is limited to gamers in the US, UK, and South Korea for now, with the available games to play including Halo 5: Guardians, Gears 5, Killer Instinct, and Sea of Thieves.

In order to play you'll need the Xbox Game Streaming (Preview) app installed on your Android device, which needs to be running Adrnoid 6.0 or greater and have Bluetooth 4.0+ compatibility. Controlling games requires the use of a compatible Xbox Wireless Controller with Bluetooth, and you internet connection must be capable of at least 10Mbps for smooth streaming.

Footage of Project xCloud in action is already appearing on YouTube, and it looks to be a lag-free experience so far. We do have to keep in mind that this is a very limited preview of the service, though, and won't really stress Microsoft's Azure servers too much. The real test will be when Microsoft rolls out xCloud to everyone.
