Last night, Google took the wrappers off one of the worst-kept secrets in recent memory. Yep, Google Play game services. FINALLY, there's a reason to have a Google+ profile.

As of right now, though, Android (and indeed iOS) game developers are scrambling to integrate Google Play game services into their titles.

Some, however, already have done so. Clever boys.

Probably the biggest name to gain full support for Google Play game services (i.e. new Achievements, cloud saves, real-time multiplayer, and leaderboards) is Gameloft's grunt-blasting FPS Modern Combat 4: Zero Hour.

Two further Gameloft games, Asphalt 7 and Dungeon Hunter 4, will get the same Google Play game services treatment in the coming weeks.

Rather helpfully, Google has published a list of all the Google Play game services launch titles. Rather unhelpfully, The Big G opted against plonking names underneath them all.

Here's a Pocket Gamer mini-challenge for you, then, eh. How many Android games can you identify in the image above?

First person to correctly identify all 32 wins nothing. Post your 'winning' entries in the box below.

Ripping it up

To help you on your way, I can reveal that Vector Unit's Bronze Award-winning Beach Buggy Blitz and Silver Award-winning Riptide GP are both Google Play game services launch titles.

Gravity Guy, Eternity Warriors 2, and Chip Chain are all on that Wall of Fame, too.

Hopefully, it won't be too long until Google Play game services integration is so common we won't have to post lists of games that support Google's new initiative. Three of my fingers are now being crossed.
