Rovio Now Lets Users Worldwide Sync Angry Birds, The Croods Gameplay Across Devices

What makes Candy Crush so addictive? A combination of perfected game mechanics, built-in social media virality, and the maddening timer that tells you can’t play right now – which somehow makes you crave the game even more. But the other thing Candy Crush has going for it is that it syncs your gameplay across all platforms – something that not all game publishers, big or small, bother to include. Case in point: Angry Birds maker Rovio is announcing today that it has finally extended its “Rovio Account” feature worldwide, allowing users of select Rovio titles to play cross-platform.

That’s right, select titles.

Apparently, building in gameplay sync and storing of users’ progress in the cloud isn’t the easiest of things to tack on after the fact.

Today, Rovio says that Rovio Account is available worldwide, but only on the original Angry Birds game and The Croods for now. (Yeah, The Croods. Um, hooray.)

After joining Rovio Account, you can then sign in again on any iOS or Android device to pick up where you left off. It also lets you sign in and out if you’re sharing devices, like with the family’s iPad, or if you’re handing your smartphone over to the kids, for example. You’ll need to provide an email address to register, and Rovio will also send out an email, asking you to click a link to verify your account.

The company says that the next step is rolling out Rovio Account to the other Angry Birds and non-Angry Birds titles in the Rovio lineup, but did not give an ETA on that. But to give you an idea, Rovio first announced its intentions to build this feature into its games back in May of this year.

Rovio has a lot of titles to still attack, including more recent launches like Amazing Alex, Bad Piggies, Angry Birds Star Wars and the new sequel, as well as Angry Birds Friends, Space, Seasons, Rio, and forthcoming racing game Angry Birds Go.

The company crossed more than 263 million monthly active users in January of this year, which put them roughy on par with Zynga at the time, and made them bigger than Twitter.
