RealNetworks said today that it acquired Sao Paulo, Brazil-based Atrativa, a casual games Web site, to strengthen its already strong international game portfolio.

The acquisition allows Real to move into South America. Previously, it had a casual games footprint in Europe, China, Latin America and the U.S. Today, Real said it offers games to consumers through RealArcade, GameHouse.com, Zylom.com and Atrativa.com.br, accounting for more than 750,000 game downloads on a typical day.

The Seattle company said it purchased Atrativa for an undisclosed price at the end of 2006.
