Gamblers continue to return to Atlantic City’s casinos this summer, even as a contagious new variant of the coronavirus continues to spread, yet it was internet gambling that set a new monthly record in July. Figures released Monday by the New Jersey Division of Gaming Enforcement show the nine casinos collectively won $118.6 million online in July, the best month ever for a state that was an early adopter of internet betting. The previous record was $113.7 million in March of this year. July’s figure was an increase of almost 36% from July 2020, when casinos had just begun to reopen after a 3 1/2-month virus-related shutdown.
