MGM National Harbor is set to roll the red carpet on Thursday after Maryland Lottery and Gaming Director Gordon Medenica finally signed its operational license.

“MGM National Harbor successfully demonstrated that it has met the state’s legal and regulatory requirements and is ready to open,”Medenica, who signed the operations license Wednesday, said, according to The Washington Post.

Before Medenica signed the last bit of important paperwork, Maryland Lottery and Gaming Control Agency conducted tests and assessed the facility’s systems and controls, including more 3,321 slot machines and 165 table games, internal controls, employee training, technical systems and other operations.

About 7,500 people gambled with real money when they took part in the controlled demonstrations held on December 1 and 5. Neither the casino nor Maryland Lottery and Gaming immediately disclosed how much money was gambled.
