The cross-platform social gaming company SGN (Social Gaming Network) has agreed to purchase the mobile games studio Mob Science in a deal that will see it gain access to its full portfolio of games.

The LA-based casual gaming company announced the deal to buy the Californian developer founded in 2008 on Thursday. Financial terms of the deal were not disclosed.

“Mob Science is a proven game development company with collectively over 75 years of experience in top-tier social game creation,” Chris DeWolfe, a co-founder of MySpace and now CEO of SGN, said.  “Both SGN and Mob Science stand for quality, enabling us to continue our strategic growth and market expansion.”

Mob Science was helped along in its early days by the notable social gaming company Zynga, which also published Legends: Rise of a Hero, shown below. Although Zynga wasn’t publicly named as an investor at the time of Mob Science’s $1 million seed round, we’re told the social gaming giant invested in the startup.

SGN said the purchase will add the 11 full time staff of Mob Science to its team of more than 80 people, along with increasing its social gaming catalogue by about a dozen or so titles. It’ll also net the company a 50 million increase in its user base of installed apps.

The news followed an announcement from SGN on Monday confirming it had hired several new executives from rival companies such as Zynga, Storm 8, LucasArts and Playtika.
