PapayaMobile's portal, which is the leading social gaming network on Android, currently boasts 15 million users, though the company also offers developers what it claims is the most comprehensive social graph for gaming on iOS as well as Google's platform.

More products are set to be launched further down the line, the company claims, with the investment also set to be used to extend PapayaMobile's portfolio.

"Since launching our Papaya gaming platform last year, we have had over 350 applications integrated into our network, all of which have benefited from the viral capabilities of our social graph," said CEO and co-founder Si Shen.

"As our momentum on Android continues to grow, our latest funding from Keytone Ventures, an expert in the Chinese mobile market, and DCM, a pioneer in the gaming and social network investment space, will help us continue to expand our social network across the globe."
