Here's a quote from the press release which makes me think it may be slots only...

"The property will feature a casino including 86 new slot machines, full-service restaurant
and bar with amazing craft cocktails, and a delicious new menu that will include everyone's
most loved pizza in Deadwood which will be prepared in our brand-new state-of-the-art kitchen."

I hope I'm wrong - it would be great if they offered table games and chips!
