Gaming technology provider GAN has finally revealed the identity of its new European-facing real-money online gambling client.

On Tuesday, GAN announced that its heretofore secret ‘Overseas Internet Casino’ partner was none other than the Chickasaw Nation, the Oklahoma tribe that is the biggest multi-property US client of GAN’s Simulated Gaming free-play social casino product.

GAN had been teasing the identity of its overseas client for over a year, but the company says it can now reveal that the tribe’s WinStar.com site launched late last year and is now available in an unspecified number of regulated European markets.

The Chickasaw Nation operates over 20 gaming venues in the state of Oklahoma, and WinStar is the Chickasaw’s primary gaming brand, adorning the tribe’s flagship WinStar World Casino and Resort in Thackerville.
