What no one disputes is that gaming revenue helps fund tribal programs for education, infrastructure, health care and more. The compact defining the state-tribal agreement is the subject of an ongoing and tense political fight. In Oklahoma, tribal nations have exclusive rights to operate casinos, except for games administered at horse racing tracks. “We’re third in the nation for number of slot machines, and yet we’re 20th in the nation in money for treatment, awareness and so forth,” said Wiley Harwell, director of the Oklahoma Association on Problem and Compulsive Gambling. Similarly, 38 percent think the government should do more. According to a June study from the National Council on Problem Gambling, 60 percent of surveyed state citizens think the gaming industry should do more to help addicts. Oklahoma ranks as the fifth most gambling-addicted state in America, with an estimated 75,000 problem gamblers and historically high numbers of gambling-related embezzlement cases.

Patrons file in - some wearing jeans and t-shirts, some wearing dresses or suit jackets. A cold front has chilled the December air, but a rainbow of neon lights warm the building’s sleek exterior. Friday, cars crowd the parking lot of Riverwind Casino just south of Norman.
