Slots machine revenue at Pennsylvania casinos declined by more than 9 percent in February as compared to a year ago, the state Gaming Control Board reported on Monday.

The board blamed the 28-day month for part of the decline. As 2012 was a leap year, February had 29 days a year ago.

The Sands Casino Resort Bethlehem posted a 7-percent drop in gross slots machine revenue as opposed to a year ago, pulling in a little more than $23.5 million, a drop of $1.8 million.

Statewide, gross revenue from slots was $195.9 million, a drop of nearly $20 million from 2012. Tax revenue from slots play statewide was $105.1 million, the board reported.

Every casino in Pennsylvania pulled in fewer dollars, except for the Valley Forge Casino Resort, which was not open in February 2012.

When comparing just the 10 casinos that were open in 2012, slots revenue declined by 11.5 percent in February, the board said.
