Making yet-another-addition to its expanding empire, Yahoo has acquired PlayerScale, a California-based gaming infrastructure startup. But financial details of the deal haven’t been disclosed yet.

PlayerScale is a cross-platform game infrastructure startup that provides tools for games played by 150 million users on platforms such as iOS and Android. The company was founded in 2009 and had a team of 14 people, out of which 7 are joining Yahoo as part of the transaction.

According to Yahoo PR, it will continue to support and grow PlayerScale’s technology, and build great new experiences on Yahoo! using the PlayerScale platform.

PlayerScale CEO Jesper Jensen also sounds quite happy by the deal and said,

“Today is a great day — both in our journey with PlayerScale and for users of our Player.IO product. We are happy to announce the next big step toward our goal of building the best possible gaming infrastructure platform: we have been acquired by Yahoo! And don’t worry, we’re not going anywhere. Our platform will continue to support the same great games that you love playing today … and in fact, it will only get better from here!

With Yahoo!’s backing, we can crank out awesome products and improvements to our platform faster than ever before. We will continue to support our existing product and deliver new services to help you grow and manage your success in cross-platform gaming — whether it’s casual, social or mobile.

Today marks a milestone for PlayerScale and I want to sincerely thank the team, our developers and millions of users for the adventure so far and can promise there will be more to come.”

This is second acquisition by Yahoo in a row, after it bought Tumblr earlier last week at a $1.1 billion price tag. By acquiring Tumblr, Yahoo would gain much larger social presence and boost its ability to attract younger audiences as it attempts to counter the influence of rivals like Google and Facebook. Other recent acquisitions by Yahoo include Stamped, OnTheAir, Snip.it, Alike, Summly, Jybe, and Astrid.
