New Jersey saw a 23% year-on-year rise in online gaming revenue in June.
The US state’s casinos reported flat takings during the month, at $197m (€170m), but soaring web revenue helped it to an overall rise of almost 2%.
New Jersey's Monthly Internet Gross Revenue Report showed that legal online casinos generated $20.2m during the 30 days in June.
While it was the fourth consecutive month to see more than $20m generated online, the figure was down slightly on the $21.1m reported in 31-day May.
Caesars was the only Atlantic City casino to report a revenue decrease in June, down almost 2% to $24.6m.
The largest percentage increase was posted by the Golden Nugget, which was up almost 23% to $23.5m.
Golden Nugget widened its lead in terms of online offering as it soared to $5.5m. The Borgata was second at $3.8m.
New Jersey's online casinos have now generated nearly $600m in gross revenue since online gambling was legalised and regulated in November 2013.
Steve Ruddock, lead analyst for gaming platform PlayNJ.com, said the potential for online gaming highlighted in New Jersey should be noted by other states.
“At its current pace, New Jersey's online gambling industry will blast past the $700m milestone before it celebrates its fourth birthday in November,” said Ruddock.
“Instead of listening to agenda-driven hypotheticals and what-ifs about online gaming, lawmakers considering online expansion in states such as Pennsylvania should focus on the sustained and prodigious growth occurring in New Jersey.”
