Winnings at Baton Rouge’s three riverboat casinos increased by 2.8 percent in September, but the higher winnings were all a result of increased business at L’Auberge.

The Baton Rouge gambling market brought in nearly $21.7 million in September, according to figures released by Louisiana State Police. That compares with $21.1 million in winnings during September 2014.

L’Auberge Baton Rouge brought in $11.8 million during the month, a 7.9 percent increase from the nearly $11.0 million that was won during September 2014.

That offset revenue drops at the two downtown casinos. Hollywood Casino was the biggest loser, going from nearly $5.4 million in winnings during September 2014 to $5.2 million, a 3.1 percent decrease.

Business at the Belle of Baton Rouge fell by 2.4 percent from $4.7 million in September 2014 to $4.6 million.

Statewide, the 15 riverboats, four racetrack slots casinos and Harrah’s New Orleans casino brought in $206.1 million in September, a 12.8 percent increase over the September 2014 total of $182.8 million. The increase would have been much narrower if not for the Golden Nugget Lake Charles. The riverboat casino, which opened in December, had nearly $21.8 million in winnings for the month.

The New Orleans casino market saw its winnings increase by 4 percent in September, thanks to increased winnings at the local riverboat casinos and Harrah’s.

Harrah’s, the market’s three riverboats and the slots at the Fair Grounds racetrack brought in $49.1 million, compared with $47.2 million in winnings during September 2014.

Revenue at Harrah’s rose by 2 percent, increasing from $24 million in September 2014 to $24.5 million. The casino’s winnings have been seesawing between beating 2014 numbers and falling short.

The casino has blamed its revenue drops on the New Orleans smoking ban, which forces gamblers to leave the slot machines and table games for a cigarette.

Lake Charles, the state’s largest casino market, saw its winnings go up by 38.3 percent, thanks to the addition of the Golden Nugget. The three riverboats and slots at Delta Downs brought in $72.6 million, compared with $52.5 million the year before.

Shreveport-Bossier City was up 1.1 percent, with the six riverboat casinos and the slots at Harrah’s racetrack bringing in $56.1 million.

The Opelousas market, represented by the slots at Evangeline Downs, was up 2.8 percent to $6.7 million.
