Parx’s clock shows the days, hours, minutes and seconds until launch, scheduled for the first day allowed by the Pennsylvania Gaming Control Board (PGCB).

The online casino will include slots, blackjack, roulette, video poker, baccarat, live dealer games and more.

At present, no other operators are scheduled to launch an online casino on the same day.

However, the PGCB is due to meet on 10 July, where more details could become clear if others indeed intend to compete with Parx on launch day.

Pennsylvania’s online sports wagering market went live in May. Overall sports betting revenue still fell month-on-month to $2.9m, a 31% drop.

But May's overall gaming revenue in the state was up 3% year-on-year to $286.1m, during the most recent month for which the PGCB has released results.
