The Medinah Temple gaming floor is the first legally licensed gaming casino to operate in Chicago. The Medinah Temple gaming floor, classified as a “temporary” facility to stand in for Bally’s planned permanent casino resort on the North Branch of the Chicago River, contains nearly 800 slot machines and 56 table games. The doors opened on Saturday, September 9. After a tech rehearsal demonstrated readiness for full operations, Illinois casino regulators granted full operating licensure to the Bally’s gaming floor in Chicago’s River North.
