Harrah's Entertainment

(HET)

has completed its acquisition of

Caesars Entertainment

, a deal that creates the world's largest casino company.

As Harrah's had predicted, the $6.8 billion deal closed Monday after receiving the blessing of Nevada regulators on Friday.

The merger is closing as casino companies continue to ride a gaming boom, particularly in Las Vegas. The industry has also seen consolidation in its top ranks. In April,

MGM Mirage

(MGM) - Get Report

closed its acquisition of

Mandalay Resort Group

.

The combined Harrah's and Caesars has more than 40 casinos operating primarily under the Harrah's Caesars and Horseshoe brand names. The company also has more than 40,000 hotel rooms and almost 100,000 employees.
