The 18 retail sportsbooks in Pennsylvania don’t get as much attention as the 14 online/mobile sites on which to place sports bets.

After all, the bets placed in person at 15 casinos and three off-track betting parlors represent only 8% of the overall wagering volume. These brick-and-mortar venues aren’t heavily promoted on television and social media the way the FanDuels and BetMGMs of the world are.

But the casino operators count on them to attract customers, create excitement within the property, and, yes, even raise a few dollars to help keep the bright lights on 24/7. The latest report from the Pennsylvania Gaming Control Board that showed record volume of $797.1 million in overall sports betting last month included $64.8 million in bets placed in person, generating $6.1 million in revenue for the casinos (compared to $65.1 million grossed by online sportsbooks).
