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.

Companies in Baton Rouge collected nearly 9.8 percent of the state total, Louisiana State Police reported Tuesday.

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 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 only had two riverboat casinos.

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.

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 the same month a year earlier.

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 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 $172.7 million, which was 20.7 percent higher than combined collections for December 2013.

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