MGM Resorts’ National Harbor casino continues to run roughshod over its Maryland competitors, at least in terms of monthly gaming revenue.

Figures released Thursday by the Maryland Lottery and Gaming Control Agency show the state’s six gaming venues generated combined revenue of $134.5m in September.

The total is 38.6% higher than the Agency reported in the same month last year, although that predated National Harbor’s December 2016 opening. In a direct comparison of the five casinos that were open in both periods, revenue fell 12.3% year-on-year.

This September’s figure is also $3m less than the casinos reported in August 2017, which is understandable, what with all those elementary kids back in school instead of playing slot jockeys. (Relax, people, that was a joke. Besides, everyone knows elementary school kids prefer baccarat.)
