Riverboat casinos’ winnings dropped 5.8 percent in the Baton Rouge market in October compared to a year ago, with L’Auberge and Hollywood Casino slipping while the Belle of Baton Rouge posted a gain.

Winnings at the three boats slipped to $21.4 million from $22.7 million last year, figures released by the Louisiana Gaming Control Board show.

L’Auberge continued to rake in more than the Belle and Hollywood Casino combined. However, L’Auberge’s revenue dipped 1.7 percent to $11.0 million in October from last year’s $11.2 million. Hollywood Casino dropped 19.3 percent to $5.6 million from $6.9 million. The Belle increased its winnings by 4.4 percent to $4.8 million from $4.6 million a year ago.

October marked the second month of year-over-year comparisons with Baton Rouge as a three-boat market.

The much-hyped L’Auberge casino opened in September 2012, attracting gamblers to immediately make an impact by raking in more than its two competitors combined and growing the Baton Rouge market’s total revenue by 69 percent above September 2011’s $14.8 million.

With the latest figures, Baton Rouge is still a bigger market than in 2011, but the growth margin was about 49 percent. That’s better than in September, when the margin was 41 percent higher than September 2011.

Statewide, gambling revenue from riverboats, racetrack casinos and the land-based Harrah’s casino in New Olreans totaled $187.3 million, a 1.3 percent increase from October 2012. Only the riverboat revenue was up over 2012.

The state’s 14 riverboat casinos, one more than a year ago, combined for a 5 percent gain to $132.3 million in October. Harrah’s New Orleans Casino fell 9 percent to $25.9 million.

The state’s four racetrack casinos took $29.1 million from gamblers in October, 4.1 percent less than a year ago. Evangeline Downs in Opelousas bucked the trend with a slight 0.1 percent gain to $7.1 million. The Fair Grounds in New Orleans was down 5.8 percent to $3.7 million; Delta Downs in Venton, down 1.9 percent to $13.7 million; and Harrah’s Louisiana Downs in Bossier City, down 14.1 percent to $4.6 million.

The Baton Rouge riverboat market joined New Orleans as the only two markets in the state with lower winnings in October. Winnings at New Orleans’ three riverboats dropped 7.5 percent to $20.6 million.

Shreveport-Bossier City — with a sixth riverboat casino in its fleet this year compared to last year — jumped 15.9 percent to $52.3 million.

The two riverboat casinos in Lake Charles combined for a 5.8 percent gain to $38.0 million.
