Shown below is a list of Oklahoma casinos. Some Oklahoma Indian casinos offer traditional Class III slots, which are the same type of slots that you will find in major gaming cities, such as Las Vegas. Class II gaming machines have the appearance of slot machines, but are actually games of bingo and the spinning video reels are for entertainment purposes only. These Native American casinos are allowed to offer both Class II and Class III gaming machines. All casinos in Oklahoma are affiliated with the Native American Tribes.
