Maryland's newest slots casino is expanding Thursday evening, opening more floor space with over 500 additional gambling machines and another bar.

At 6 p.m., the two-month-old Maryland Live Casino at Arundel Mills mall will open the Rams Head Bar and additional floor space with 531 more slot machines and electronic table games, according to a statement released Thursday by the casino.

The Cordish Cos., the owner and operator of the $500 million casino that opened June 6, expects to complete the facility by the end of November. A live music venue, an upscale steakhouse and more than 1,000 more slot machines are planned.

The casino, Maryland's largest, brought in more than $28 million in revenue to the state treasury during its first 25 days of operation.
