The casino floor at the Rio is one of Vegas's most lively places to play. The casino is perhaps best known for hosting the annual World Series of Poker, six weeks worth of poker tournaments that culminate with the "Main Event" in which one pro takes home millions of dollars in cash. Elsewhere, the gaming floor offers table games with some of the worst odds in town (it's one of the only Vegas casinos to spread Mississippi Stud). Perhaps the spontaneous performances by sexy
"bevertainers" (cocktail waitresses who double as dancers) will provide a pleasant enough diversion for you to overlook the house edge. There's also more than 1,200 slot machines, including dozens of different statewide progressives.
