Governor Arnold Schwarzenegger approved a bill that allows Red Hawk Casino to operate up to 5,000 slots, the latest head-turning gaming compact between the state and a tribe. The casino, under construction in Shingle Springs, plans to open by the end of this year, with room for 2,000 slot machines, but could expand down the road under the compact. It’s a much different deal than existing local casinos have, such as Cache Creek Casino Resort and Thunder Valley Casino. Those tribes pay a fixed amount per machine. Red Hawk Casino will pay revenue on a sliding scale to the state under the 21-year compact. The casino is hiring about 2,000 employees for everything from card dealers to child-care center workers. The Shingle Springs Band of Miwok owns the casino, which will be operated by Lakes Entertainment Inc.
