Google+ Welcomes Its First ’Ville From Zynga

The No. 1 game on Facebook, Zynga’s CityVille, has just been added to Google’s social game network.

In August, Google announced it had added gaming to Google+, introducing a dozen or so games from a handful of developers.

Zynga, which is the leader on Facebook and has received an investment from Google, initially contributed Zynga Poker. Today, it added CityVille+ to the new game platform.

In a blog post, Zynga writes: “CityVille grew to become our largest game on Facebook, so naturally we wanted to ‘build’ a presence for it on Google+. Ultimately, we want to make our games accessible to everyone, everywhere — no matter where they play or what platform they play on.”

So far, the success of the Google+ games network has been limited, given the comparatively few users on the network versus Facebook. Today, Liz Gannes reported that Google+ has roughly 43.4 million users, according to the latest estimates. On the other hand, Facebook now is claiming up to 800 million on a good day.

Rovio’s Angry Birds, which has not yet launched on Facebook, is claiming to be the most popular game on Google+.

Recently, Zynga’s dominance on Facebook has been questioned by other recent rising stars, including the popularity of Electronic Arts’ the Sims Social, which has a chance to unseat CityVille as the No. 1 game in the not so distant future.
