Scoreloop's decision to branch out from its base on iOS – instigated in timely fashion before the words Game Center had even crossed Steve Jobs' mind – seems to have brought the firm nothing but good news.

The Munich-based company has already revealed that Android is now outpacing iPhone in terms of sheer growth, and now sign ups across all platforms have hit 1 million new users a week, mainly on Android. 

Millions strong

It's a milestone that coincides with the news that the platform delivered 100 million game sessions during 2010 - a session defined by Scoreloop as a user actively engaging the platform's social connectivity features.

Players also uploaded 350 million high scores to Scoreloop across the course of the year.

Driving mobile social

"One million new users a week is a magic number for Scoreloop, and it's proof that users are actively taking advantage of the social element that we’re enabling thousands of developers to creatively integrate into their mobile games," said CEO Marc Gumpinger.

"Today's announcement represents an accelerating rate of growth that’s no doubt driven by the significant SDK uptake and an increasing number of developers using our tools to leverage the freemium model."

Scoreloop enjoyed something of a boon over Christmas, gaining 1.3 million new users over Christmas week itself – a surge that has no doubt helped inflate its average sign up rate to its current level.

Demonstrating its growth over a more long term period however, it was signing up 300,000 new Android users a week back in May 2010.
