The Pennsylania Gaming Control Board on Wednesday approved an expansion at Parx Casino in Benesalem, that will add 268 slot machines and boost annual revenue by and estimated $15 million to $20 million.

Parx, which is owned by Greenwood Gaming & Entertainment Inc., had $507.6 million in gambling revenue in the 12 months ended June 30, ranking second in Pennsylvania behind Sands Bethlehem.

A portion of the expansion, which will increase Parx's gaming floor 15 percent by expanding into space that is currently unused, will be ready to open Nov. 5, Parx officials told Gaming Board members.

The remainder of the project, including the new XLounge, is expected to be finished by Christmas.

The project will add nine table games, with an emphasis on black jack and roulette tables, which are at capacity on weekends, a Parx official said.

Parx started with four roulette games five years ago and will have 15 after this expansion is done.

The company did not say how much it planned to spend on the project.
