Buffalo-based regional casino operator Delaware North has acquired social casino developer Ruby Seven Studios.

On Thursday, Delaware North announced that it had acquired 100% of Ruby Seven for an undisclosed sum. The purchase was made six months after the two companies had formed a strategic partnership to develop and deploy free-to-play online casino games. Ruby Seven’s equity had previously been held by investors including Rush Street Gaming.

The privately-held Delaware North says the deal will allow it to launch social casino operations at the casinos and racinos it manages across seven US states as well as with other brick-and-mortar casino operators. Delaware North also operates a range of non-gaming venues, including resorts in Australia, US state parks and food services at airports around the globe.

Ruby Seven, which has around 100 employees spread across two studios in Nevada and India, has existing social casino tie-ups with brick-and-mortar operators including the Tropicana in Atlantic City and the Pechanga Resort & Casino in Calfifornia, while the company also provides services to UK online bookies Coral Interactive.
