Japan’s leading mobile social gaming platform, GREE, has announced that they have put $104 million on the table, to get their hands on the popular gaming service OpenFeint. In addition to Apple’s Game Center, OpenFeint is the largest game service for the iPad, iPhone and iPod Touch.

The service was also made available for Android in September last year, something that made it possible for Android and iOS users to play multiplayer games against each other.

A total of more than 5000 games are available via the service, including including the top selling games Fruit Ninja and Tiny Wings.

“We are excited that GREE shares our belief in the OpenFeint network and are ecstatic to partner with a renowned global leader to build a multi-billion dollar business,” says Jason Citron, CEO and founder of OpenFeint. “Together, we will deliver the strongest global ecosystem of gaming networks to our combined 100 million users.”

In order to further expansion their growth internationally, they will soon be opening offices in Beijing, Singapore and London. Both companies currently hiring, and OpenFeint is expected to double in size in 2011.
