The Pennsylvania Gaming Control Board on Wednesday announced the fines against HSP Gaming LP, which operates Sugarhouse.
The board says one case happened when a person banned from gambling in the state played table games at the casino from June 29 to July 3.
Another case happened in August when the state says a banned gambler played slots and table games at Sugarhouse. Officials say the third case happened in May.
A message left with a casino spokesman was not immediately returned.
