Under one, Horseshoe would pay $6,000 to the commission. It received a violation notice in February alleging that "on five separate occasions, underage individuals were admitted into the casino and onto the gaming floor," according to an online copy of the document.
Under another agreement, Horseshoe would pay $2,000. A third agreement calls for Maryland Live to pay $1,000.
The remaining agreements didn't include penalties. A Horseshoe representative did not immediately respond to a request for comment. A query to Maryland Live was forwarded to a general manager, who was unavailable.
Keeping underage patrons out is a persistent problem for casinos. Each month, casino compliance reports compiled by state regulators contain examples of the problem.
In March, for example, three underage customers entered Horseshoe using suspected phony identification, while two others "entered the casino by climbing over the barrier into the smoking terrace," the latest compliance report said. All were evicted.
