Coronavirus in Oklahoma: Four tribes announce extension of casino closures Randy Ellis, The Oklahoman · April 29, 2020 at 7:40 am Oklahoma tribal casinos operated by the Chickasaw, Cherokee, Choctaw and Muscogee (Creek) nations will remain closed at least through May 15, tribal officials said Tuesday. Oklahoma has nearly three-dozen tribes that operate gaming operations at more than 130 locations in the state. Those gaming operations range from electronic machines at gas stops to full scale resort casinos. All the tribes closed their casinos in March in an effort to help slow the spread of COVID-19. Each tribe has its own government and will be making its own decision on when to reopen. The Chickasaw, Choctaw, Cherokee and Muscogee (Creek) nations all have been paying their casino workers while gaming operations have been suspended and said they plan to continue doing that at least through May 15.
