Gamblers lost more than $234.8 million at Louisiana’s 20 major gambling venues in December, a combined year-over-year increase of 14.4 percent.

Much of that gain came from the addition of a third riverboat in Lake Charles, which draws many of its customers from Texas.

Nearly $55.9 million of that money — about 23.8 percent, went to companies in New Orleans, Louisiana State Police reported Tuesday.

In New Orleans last month, Harrah’s New Orleans Casino — the state’s only land-based casino — took in 6.5 percent more receipts than December 2013. Harrah’s had revenue of nearly $30.35 million last month.

The gambling machines at the Fair Grounds horse track pulled in another $3.9 million in December. That was 7.1 percent more than the same month a year ago.

New Orleans’ three riverboat casinos — Amelia Belle, Boomtown New Orleans and Treasure Chest — pulled in a combined $21.65 million in December, an increase of 5 percent over December 2013.

Amelia Belle pulled in $4.19 million of that total. Boomtown New Orleans collected $9.42 million, and the Treasure Chest was filled with more than $8 million.

The state’s biggest bucks, however, washed into Lake Charles’ three riverboat casinos last month. Those receipts totaled $72 million, which was 59 percent more than was collected in December 2013 when Lake Charles had two riverboats. It also was 30.7 percent of the combined take reported by State Police.

Companies in Baton Rouge collected nearly 9.8 percent of that combined total.

Baton Rouge riverboat casino receipts totaled nearly $22.85 million in December.

That was an overall increase of $295,264 over December 2013 receipts, despite a year-over-year dropoff of $341,729 at Hollywood of Baton Rouge.

Last month, Hollywood raked in a total of $5.44 million. Belle of Baton Rouge pulled in another $5.17 million, and L’Auberge Baton Rouge drew $12.24 million.

The combined take at the six casinos in Shreveport-Bossier City increased 2.8 percent over receipts for December 2013 and totaled nearly $56.19 million.

Collectively, Louisiana’s 15 riverboats became magnets last month for a total of $172.7 million, and that total was 20.7 percent higher than combined collections for December 2013.

Gambling machines at Louisiana’s four horse tracks — including the Fair Grounds — pulled in another $31.77 million in December, an increase of 3.9 percent over the same month in 2013.
