Two months later, Jack entered into an agreement to sell the Greektown casino to Vici Properties and Penn National Gaming for a total of $1 billion. In September 2018, it was reported that Gilbert was looking to sell Jack Entertainment and exit the casino business. It also introduced a new customer loyalty program, ClubJack. The company stated it planned to spend $40 million on the rebranding. Throughout 2016, the company would also rebrand its casinos under the Jack name. On February 23, 2016, the company announced it was changing its name from Rock Gaming to Jack Entertainment. That same year, Rock Gaming bought out Caesars's minority equity interests and management contract, and assumed full operational control and full ownership of its Ohio gaming properties. In April 2015, the company took on an operational focus and was approved by Ohio Casino Control Commission to be licensed as a management company. In that same year, the company acquired the Greektown Casino-Hotel in Detroit. The company quickly expanded in 2013, opening ThistleDown Racino in the nearby Cleveland suburb of North Randall and Horseshoe Casino Cincinnati.

In May 2012, Rock Gaming, in a joint venture with Caesars Entertainment, opened Horseshoe Casino Cleveland as well as gained a stake in a Kentucky racetrack, Turfway Park. The company was formed as the seven men backed the Ohio Casino Approval and Tax Distribution Amendment, which was ultimately approved by voters in November 2009.

Jack Entertainment was founded as Rock Gaming in 2009 by seven businessmen led by Dan Gilbert, as chairman of its board and Matt Cullen as chief executive officer. The company operates two gaming facilities in Ohio, Jack Cleveland Casino and Jack Thistledown Racino. Jack Entertainment (formerly known as Rock Gaming LLC from 2009 to 2016) is a gaming, hospitality, and entertainment company based in Cleveland, Ohio.
