The Pennsylvania Gaming Control Board reports slot machine revenue generated in March of this year is the second highest monthly total since the casinos opened in 2006.
The total gross revenue of $229,335.372 was slightly lower than March of 2012.
State Officials report Pennsylvania's 11 casinos have reported lower slot machine revenues in five of the past six months.
The Pennsylvania Equine Coalition says revenues at the six racetrack casinos have declined 6 percent during the first nine months of the fiscal year.
Fred Lipkin of the Hollywood Casino says they experienced a 2.4 percent drop in slot revenue for the month of March. He says bad weather kept casino goers home for four days.
Some experts say table games and competition from casinos other states are contributing to the decline. Lipkin says there is no hard evidence that table games have had an impact on slot revenue and he says their focus is catering to their customers who live within a 75-mile radius.
