King of casual plans to use money to aid expansion into social media and reaching new audiences.

The capital marks the first PopCap, maker of Bejeweled, Peggle and Plants Vs Zombies, has secured in the 10 years the developer has been in business.

“We're excited to have additional working capital that lets us be more aggressive with our expansion into social media and reaching new geographies," says David Roberts, CEO of PopCap in a press release. The money will also perform as working capital and be earmarked for potential acquisitions.

Though PopCap has had great success in selling games through demos on its own website and through affiliate games portals, it hasn’t yet made progress in the new gaming frontiers of social networks like Facebook, where companies like Playfish and Zynga attract millions of players a day.

Indeed, Facebook was behind making the deal with Meritech Capital Partners. According to Roberts: "Meritech is a premier late-stage investment firm with a portfolio that includes some of our most important business partners such as Facebook.”

PopCap has grown to number over 240 full time employees all over the world, and has remained profitable since its founding in 2000.
