Revenue generated from people playing slot machines at Pennsylvania casinos fell more than 4 percent, or about $9 million in April, marking the fifth straight month of decline, according to the Pennsylvania Gaming Control Board.
The best showing compared with April 2012 was Valley Forge Casino Resort, which the board said increased its revenue by about a third.
The casino came online a little more than a year ago.
Of the 10 other casinos that have been operating longer in their markets, only two registered slots revenue increases.
Neither of them hit or surpassed 1 percent growth, according to numbers provided by the board.
Gross revenue from all slots play in the commonwealth was about $205.2 million, generating tax revenue of about $110.4 million.
Slots gross revenue at Hollywood Casino at Penn National Race Course in Dauphin County declined about 3.7 percent in April to about $20.4 million, the board said.
Despite the losing streak, March had been a particularly strong month for slots revenue in Pennsylvania.
The total for the month was the second-highest on record, falling only behind March 2012.
