The Palo Alto office of GSN Games, which is behind top grossing games such as Solitaire TriPeaks and GSN Grand Casino, is expanding.

Created when the social casino game publisher acquired SilverTree Games (Cordy, Sleepy Jack) in 2013, the studio is upgrading to a 4,919 square feet office that gives the 24-person outfit the headroom to expand to 34.

Indeed, it's also in hiring mode with available positions for engineering, game production, product management and art.

You can get more details here, including open positions across all GSN's studios in Boston, Santa Monica, San Francisco, Ukraine and India.
