And that's not just about iPhone plants and zombies.
PopCap CEO Dave Roberts says mobile is now around 25% of the company's business, with iPhone success complemented by existing J2ME and BREW sales.
"iPhone has been huge for us," he tells TechFlash.
"I continue to be amazed at how much business we do on the iPhone. About a quarter of our business is mobile, in general."
PopCap has had big success on the App Store with Plants Vs. Zombies - which famously grossed $1 million in revenues in its first nine days - and Bejeweled 2.
However, Roberts says the company continues to "sell a lot of Java/BREW games" through its own efforts and its partnership with EA Mobile.

The next mobile frontier for PopCap? Android.
"We are certainly working on Android stuff. It is not quite as clean of an ecosystem as the iPhone is," says Roberts.
Meanwhile, PopCap also continues its push into social gaming, with Roberts claiming the company is on course to make $1 million from Facebook Bejeweled in August alone.
