The land-based casino operator will be offering NetEnt games to online players in the state, including its range of table games and Divine Fortune.
NetEnt games first went live in Pennsylvania last year after the supplier was granted an Interactive Gaming Manufacturer Conditional License by the Pennsylvania Gaming Control Board (PGCB).
The supplier signed a number of customer agreements with several gambling operators in the state prior to the market's opening.
Commenting on the Wind Creek launch, Brian Kraft, NetEnt vice president commercial, Americas, said: “It’s a major achievement to be supporting Wind Creek in its online journey.
“The deal underlines our status as a go-to supplier in Pennsylvania both with established operators and emerging brands.
“Given the strong performance of our content with local players, this partnership will no doubt see Wind Creek make a big impact in the online landscape.”
Pennsylvania gaming revenue saw strong growth for the month of August. Despite limits to occupancy, the state’s casinos saw a 6% year-on-year revenue increase last month, reaching $310.7m.
