After just announcing the purchase of Tumblr earlier this week, Yahoo (NASDAQ: YHOO) just acquired cross-platform gaming software company PlayerScale today. The company creates gaming software that can be used on multiple platforms, which are played by over 150 million people worldwide, and adds 400,000 new users every day.

The news was announced on PlayerScale's website, with the company stating that it won't be shuttered by Yahoo. PlayerScale said it will continue to support existing services, and create new ones, as well.

PlayerScale said on its site that: "Our goal has always been to help developers build the best possible games, without having to worry about building and scaling the infrastructure required to operate today's biggest successes. In working with the folks at Yahoo!, it has become clear that we share this passion."

No details on how much Yahoo paid for PlayerScale have been released yet, and Yahoo has yet to provide any other details of the acquisition.
