EA will buy PopCap for US$750 million plus multiyear earn-outs. The deal includes $650 million in cash and $100 million in stock. In the earn-out, PopCap sellers will be entitled to additional cash consideration depending on certain non-GAAP (generally accepted accounting principles) earnings milestones through December 2013.

EA already has a wide range of games for PCs, gaming consoles, mobile devices and social networking sites. Some of the famous EA games include "The Sims," "Need for Speed," "Star Wars" and sports-themed games. PopCap Games will add a range of popular casual games such as "Bejeweled" and "Zuma" to EA's portfolio.

EA's reach will help push PopCap games into more digital devices in more countries, EA said. Casual games that do not demand extreme graphics are being increasingly used on smartphones and tablets. Games rank as some of the top downloaded apps .

Gartner last week said that worldwide spending on electronic gaming products will total US$74 billion this year, and continue to grow with the growing adoption of mobile devices.

The transaction is expected to close in August this year and is subject to customary closing conditions.
