Revel, fresh from bankruptcy, was especially hoping for a strong month but took 10th place in June, as it had in May. The struggling casino, which opened in early April 2012, generated $11.6 million from slot machines and table games, a 22.6 percent year-over-year decrease.
The bottom-tier finish again for Revel came after it rolled out smoking lounges, a beach bar, and a new restaurant after Memorial Day in an effort to expand its customer base. On July 1, it started an aggressive slots promotion to refund players' losses over $100 for the month. Slots revenue at Revel was down 22 percent in June compared with a year ago.
Market leader Borgata had an 8.9 percent decrease from June 2012, generating $48.6 million.
Tiny Atlantic Club, which is still looking for a buyer, reported a 4.8 percent decline, the second lowest among the casinos, taking in $13 million.
"We are extremely pleased with June's performance," said Atlantic Club's chief operating officer, Michael Frawley. The casino "continues to significantly outperform the Atlantic City market and our prior-year profitability numbers."
For the first six months of the year, the Shore's casinos generated $1.38 billion in revenue, down 10.7 percent from the same period a year ago.
Blame for Atlantic City's steadily declining revenues has been heaped on new casinos in Pennsylvania, which had been a key feeder market for decades prior to 2006.
But even Pennsylvania is starting to feel the heat of competition. That state reported its first year-over-year decrease in gross slots revenue in June - down nearly 2.0 percent, from $2.48 billion to $2.43 billion.
"A leveling of revenue, and even a slight drop, is not surprising since no new Pennsylvania casinos opened in the past 15 months and opportunities have materialized for gamblers to play in bordering states like Ohio and Maryland, which now have casinos," said Pennsylvania Gaming Control Board spokesman Doug Harbach.
The pressure is nothing new for Atlantic City.
"Our view of continued declines into 2013 remains intact, as consumers in this market will be negatively impacted by higher taxes and commodity costs," said analyst Andrew Zarnett of Deutsche Bank.
"Further," Zarnett said, "we expect gaming revenues to be negatively impacted by incremental competition from the table games at Maryland."
