Atlantic City’s nine casinos are taking in revenue at a pace that would bring them back to performance levels not seen in years. Roger Gros at Global Gaming Business Magazine is not surprised total revenues are at $2.5 billion, with some of the nine casinos projecting a year-end total on either side of $3 billion. The last time that happened was in 2012, when there were a dozen casinos and concepts like online gambling or sports books were unheard of in New Jersey.
