Online gaming technology provider GAN has signed another brick-and-mortar casino operator for its social gaming product, but it won’t tell us who it is.

On Tuesday, GAN (formerly known as GameAccount Network) announced that it had partnered with “a commercial casino operator in America” to launch a version of GAN’s online free-play Simulated Gaming product.

GAN CEO Dermot Smurfit celebrated his company’s “thirteenth client win and our fourth major casino operator client.” It’s the company’s fifth signing this year, but like its three most recent casino operator deals, GAN says it will only identify its latest signing “following the receipt of suitable commercial and/or regulatory consents.”

The only hint as to the identity of GAN’s new client was that it was “a major multi-property casino operator in the United States.” Whoever it is, their Simulated Gaming product is expected to launch in “late 2016” and will be integrated into the client’s property rewards program.
