Well, we can’t say we’re too surprised with this one following this week’s leak, but it’s great to see Google Play game services has been officially confirmed at Google I/O this morning. The service will rival services like Game Center on iOS, and features will include cloud-based game syncing, online multiplayer, and more.

With Google Play game services and cloud-based saving, you’ll be able to sync your game progress across all of your Android devices. So when you complete a level on your Android smartphone, the same level will be automatically completed on your Android tablet.

The new service also delivers multiplayer matchmaking, allowing you to play Android games against your friends online. And like a lot of Google services, this one will be cross-platform, and it’ll be available on iOS, too — so you can play against friends with iPhones and iPads as well.

That’s one thing Game Center cannot do!

Google Play game services also boasts online leaderboards and achievements, so you’ll be rewarded for completing certain tasks within your games just like you do within console games. One of the first titles to support achievements is World of Goo, and you should see an update adding achievements today.

Google Play game services is rolling out to Android devices running 4.0 Ice Cream Sandwich and above from today.
