Developers looking to take part can download the platform's SDK from GREE's developer center, handing them access to a range of social and casual features, including leaderboards and achievements, as well as invite, request, and share services.
GREE claims it's looking for the platform's features to drive installs for developers, as well engage players and decrease acquisition costs all through the platform's socially-focused infrastructure.
The idea is, developers signed up should be free to concentrate on the business of making great games.
"The GREE platform has been built with the goal of creating a worldwide developer and player community," explains GREE's SVP of product, Ethan Fassett.
"We believe the GREE platform offers developers the tools to deliver unique and customised games to an engaged, global player base.
"We are looking forward to seeing the adoption of these new mobile-social features and helping innovate the mobile games space."
The beta launch of GREE's platform has been months in the making, with the network set to take advantage of the framework set in place by OpenFeint the social gaming network acquired for $104 million by GREE back in April 2011.
The firm has looked to boost its hand in the western market pre-launch as a result, acquiring western-focused studios such as Funzio, signing deals with prominent developers and launching its own studio in the US.
GREE's social gaming network is currently available in both English and Japanese, but wil alsol be available in 14 other languages by September, playing host to over 60 titles within its first few months.
