The story
The horse track and the speedway opened together in 1969.
The track opened its casino, Dover Downs Slots, on December 29, 1995, following the enactment the previous year of a law allowing slot machines at Delaware's horse tracks. The casino was managed by Caesars World.
In 2002, Dover Downs Entertainment, the complex's parent company, spun off the horse track and casino as an independent company, Dover Downs Gaming & Entertainment. The former parent company changed its name to Dover Motorsports.
Dover Downs assumed management of its own casino in 2004, when the management agreement with Caesars expired.
A hotel expansion in autumn 2007 added 268 additional rooms, including 52 suites and 11 spa suites, for a total of 500 hotel rooms. This made Dover Downs the largest hotel in Delaware. Toppers Spa/Salon opened in the hotel on December 29, 2007.
A $56-million casino expansion was completed in 2008, adding 500 slot machines, a porte-cochere and atrium lobby, and an upscale shopping area called the Colonnade.
The casino added table games in 2010, when they were authorized by the state.
Dover Downs began a venture into the online gambling realm in late 2013.

In 2019, Dover Downs Gaming & Entertainment completed a reverse merger with Twin River Worldwide Holdings (later Bally's Corporation), a Rhode Island–based company with several casino and racetrack properties. Dover Downs shareholders were left with a 7 percent stake in the combined company.
In June 2021, Bally's sold the land and buildings of Dover Downs to Gaming and Leisure Properties for $144 million, and leased them back for $12 million per year.
The property was renamed as Bally's Dover in November 2021, as part of Twin River's rebranding to Bally's Corporation.
