The online casino is available at play.turningstone.com on desktop computers or mobile devices, or can be downloaded through the App Store and Google Play.
The app allows players to win virtual chips, purchase chips and earn points toward future on-site purchases.
Players can play the games for free, although they can purchase more virtual chips if they run out. But only virtual chips for online play can be won; the "chips" can't be used in the casino itself, Oneida Nation officials said.
Players get 5,000 chips just for creating an account, an additional 10,000 chips for linking their TS Rewards Card and up to 2,800 chips for logging in daily, Turning Stone officials said.
