Zynga's CityVille Now More Than 25 Percent Bigger Than FarmVille

We knew Zynga’s Facebook game CityVille was a hit if the company ever had one (and it’s had several already) but the growth that it is displaying is simply mind-blowing.

We’ll kick off by pointing out that the game was released on December 2, 2010, which is less than a month ago.

The company subsequently reported that in the game’s first 24 hours on Facebook, over 290,000 people had already played CityVille. A few days later: 3 million daily active users. And while you turned your eyes away from the screen for a few minutes: bang, 6 million active users.

Last week, the Sim City-esque game logged about 61.7 million monthly active users, effectively eclipsing its other hit game, FarmVille. Today, CityVille is at close to 72.5 million monthly active users, which means that it has already outgrown FarmVille (which boasts roughly 57,4 million monthly active users) by more than 25 percent.

CityVille isn’t just the biggest game on Facebook, it’s now the biggest game on Facebook with one hell of a margin.

For the record: we got the numbers straight from the application pages, as AppData’s stats on monthly active users appear to be a tad outdated at the time of writing.

And just for the heck of it, here are the current usage stats for the other “Ville” games:

FrontierVille: 30,468,070 monthly active users
PetVille: 8,394,142 monthly active users
YoVille: 6,232,611 monthly active users
FishVille: 4,969,283 monthly active users

No wonder Google investor John Doerr famously said Zynga is probably his VC firm’s best investment to date. Its growth is simply astounding.
