Zynga said today it is launching its popular social game Farmville for iPhone and iPod touch.

The company said this week marks the one year anniversary of the game and Farmville has attracted 75 million users worldwide.

The move by Zynga builds on its strategy to bring social games to a broader audience across a number of platforms. The Farmville App offers players a new social gaming experience via the touchscreen. By swiping a finger or double tapping to zoom in and out, players can view their farms, harvest crops or drive tractors.

iPhone users will receive alerts about the status of their crops and farm through push notifications. In addition, current Farmville players can tend their farms on the iPhone or Facebook at any time or place.

"Mobile devices are an extension of people’s daily social lives everywhere in the world and the Apple iPhone is the most innovative breakthrough in this area," said Mark Pincus, founder and chief executive officer of Zynga.

"We are excited to bring FarmVille to the Apple iPhone and introduce our social games to a new audience of mobile users around the world."

Zynga says it will soon introduce additional in-game features for the iPhone 4 and iOS 4 including multi-tasking functionality and improved graphics to highlight the retina display. Zynga’s catalog of iPhone and iPod touch games also include Live Poker, Mafia Wars, Vampires: Bloodlust, Scramble 2 and Street Racing.
