MGM Springfield counted $22.29 million in revenue from its slot machines and tables games last month, its third-best since it opened, while Connecticut’s casinos continued a pattern of year-over year slots revenue declines.

Gamblers put more than $184 million into the slots at MGM Springfield, leaving $16.1 million or about 8.75 percent behind for the casino as revenue, according to reports released Monday by the Massachusetts Gaming Commission. On top of that, MGM Springfield reported another $6.18 million in revenue from its table games last month.

In terms of total revenue, May was the third-best month since MGM Springfield opened in August.

“We continue to be pleased with our performance. We’re capturing market share and growing loyalty,” MGM Springfield President and COO Mike Mathis said. He added that the casino was “buoyed” in May by the start of its outdoor summer concert series and its “Food Truck Fridays” series.

Connecticut’s casinos continued to see year-over-year declines in slots revenue, the only casino revenue reported by the state Department of Consumer Protection. Foxwoods saw its year-over-year take from slot machines drop from $38.47 million in May 2018 to $37.39 million in May of this year, while Mohegan Sun saw its take drop from $51.72 million to $47.76 million.
