Pennsylvania's 10 casinos recovered from their first ever decline in slot revenue in January by posting a double-digit gain in February.

Total slot revenue was $197.9 million, a nearly 18 percent increase compared with $168.3 million in February 2010, the Pennsylvania Gaming Control Board reported Thursday.

Harsh weather was blamed for driving down slot revenue in January for the first monthly decline since casino gambling began in Pennsylvania in late 2006.

SugarHouse Casino in Philadelphia, which opened last September, help-ed push up February's results. SugarHouse's slot machines generated $13.4 million in revenue, good for eighth place industrywide.

Of the nine casinos that were operating in February 2010, there was a revenue increase of nearly 10 percent for this February.

Pennsylvania will report February's table games revenue later this month. The New Jersey Casino Control Commission will release Atlantic City's revenue figures for February on March 10.
