Through its subsidiary NetEnt Americas LLC, the supplier was granted an Interactive Gaming Manufacturer Conditional License by the Pennsylvania Gaming Control Board (PGCB) in March.

With a population of 12.8 million, making Pennsylvania the fifth large state in the US and the second largest to regulate online gaming, the market represents considerable opportunity, which NetEnt says it is eager to engage.

Erik Nyman, Managing Director of NetEnt Americas said: “I am very pleased that the market in Pennsylvania has now opened.

“We are one of the few online casino suppliers offering our games right from the start, and I am convinced that our online casino games will be much appreciated by players in Pennsylvania.”

The supplier struggled in the first half of the year, as shown by its H1 report.

With revenue declining 3% year-on-year to SEK 837m ($32.9m), NetEnt pointed to struggles in the Nordic markets.

Therese Hillman, NetEnt Group CEO, said: “The weak development in the Nordic countries continued in the second quarter, particularly in Sweden, where we have seen fewer players and lower ARPU since the new regulation was introduced at the beginning of the year.

“Looking ahead, we continue to invest in increased game production, a technical platform featuring more functionality, and live casino, to defend and over the longer term increase our market shares in all our markets.”

The launch of the online casino market in Pennsylvania provides NetEnt the chance to offset its negative results in the rest of the year.

NetEnt signed an online casino supplier agreement with DraftKings in April.

At the time of the partnership, NetEnt said it was keen to utilise the operator’s large daily fantasy sports database.
