ATLANTIC CITY — The eight remaining casinos in Atlantic City brought in more than $230 million in revenue from table games, slot machines and Internet gaming in September, a nearly 11 percent increase over last year, according to data released on Thursday.

The data from the state Division of Gaming Enforcement shows revenue declining last month in only two of the city's eight casinos: Bally's and Trump Taj Mahal. Five casinos, meanwhile, posted double-digit gains and another experienced a slight uptick in gaming revenues.

The calendar, as well as luck, helped push up revenues.

All of Labor Day Weekend fell in September this year, while most of the busy holiday weekend fell in August in 2014. Overall gaming revenues were down 5 percent in August this year.

"The industry also experienced strong table game results for September 2015," according to a release from the state Division of Gaming Enforcement, "due primarily to a more favorable table game hold percentage."

Revenues still rose nearly 10 percent in September when casinos that were operating last year but have since closed are included. Trump Plaza was the last of four casinos to close in 2014, shuttering in mid-September.

Resorts posted the largest gain in revenues in September, at nearly 32 percent, followed by Golden Nugget at roughly 21 percent.

Revenues at Trump Taj Mahal and Bally's both declined by more than 4 percent.
