It also owns and operates Harrah's Louisiana Downs in Bossier Parish, La.Ĭaesars, which changed its name in January from Park Place Entertainment Corp., had been the world's largest casino operator before the Horseshoe deal was completed. To appease regulators, Harrah's sold its Shreveport, La., casino to Boyd Gaming Corp. The Horseshoe merger made Harrah's - for the time being - the largest casino company in the world. The Horseshoe casinos are in Bossier City, La., Tunica, Miss., and Hammond, Ind. Harrah's recently completed its $1.45 billion merger with Horseshoe Gaming Holding Corp. Harrah's Entertainment, which operates heavily with riverboat casinos, has 26 casinos in 13 states under the Harrah's and Showboat names. 'I think it makes it more convenient for a lot of gamblers because they'll be able to use their slot machine cards and be better taken care of and have a great variety of options,' said Sheehan. Gamblers, however, may be pleased by the deal. The Harrah's-Caesars deal has been approved by the boards of both companies but is subject to approval by shareholders and regulators.
