Today, Playphone and International Game Technology announced that DoubleDown Casino will be made available on Playphone’s social gaming network. DoubleDown is one of the more popular free-to-play social casino game platforms, with most of its players coming from Facebook FB +0.72% and mobile. The company boasts over six million active players and 30 different games. It was purchased last year by slot machine maker International Gaming Technology in a $500 million deal.

In March, Playphone became the backbone for Verizon’s social gaming portal, which is arriving on smartphones this month. The platform allows for a single social gaming platform, allowing for gifts, in-app purchases, chats, and other social features. It has also signed deals with AT&T T +1.15% and Rogers.

Earlier this month, the company also announced that it had also gone international by becoming a branded social gaming portal for Claro Brazil, where it is launching with 150 games. That’s something that Playphone CEO Ron Czerny is particularly happy about, because he’s originally from Brazil.

“I was one of the founders of a video game association in Brazil in 1995 when I was working for CapCom,” he told me. “Now in 20 years I’ve seen both the first arcade machine and the first social gaming network there. It’s quite an amazing experience.”

Czerny has equally high hopes for integrating DoubleDown Casino into the Playphone platform. “Gamers love playing casino games and DoubleDown Casino is the world’s most popular social gaming casino.  It’s a natural fit,” he said. This story originally appeared on Forbes.
