One of the Shreveport casinos is located at a horse track. All six of them offer electronic gaming machines, as well as an assortment of table games. There are two riverboat casinos in Shreveport and four in Bossier City which is located across the Red River from Shreveport. All Louisiana riverboat casinos must remain dockside and they are not allowed to cruise. In 1991, Louisiana was the fourth state to approve riverboat casinos and its gaming law allows a maximum of 15 riverboat casinos statewide.
