Online gambling operator Bwin.party and three casinos in the Atlantic City were ordered to pay fines reaching $33,000 for violating various gambling regulations.

The New Jersey Division of Gaming Enforcement told the Borgata Hotel Casino and Spa to forfeit more than $3,700 that gambling officials said it confiscated from gamblers who failed to prove they were 21 years old, the Associated Press reported. The seizures took place between 2012 and 2013, with at least 55 gamblers involved.

Meanwhile, Borgata’s online affiliate, Bwin.party, was issued a $10,000 fine for violating the terms of a divestiture agreement by one of its stockholders.

In 2013, two PartyPoker founders—Ruth Parasol DeLeon and James Russell DeLeon—had to divest their substantial holdings in Bwin.party digital entertainment. The couple’s shares would have been placed into separate trusts to be divested over a period of 36 months starting on the day Bwin.party received regulatory approval from New Jersey.
