The state’s three casinos — Plainridge Park in Plainville, MGM Springfield in Springfield and Encore Boston Harbor in Everett — generated $90.39 million in gross gaming revenue last month, the Massachusetts Gaming Commission reported.

In addition, another $49.81 million in taxable sports wagering revenue was generated across the eight mobile/online licensees and three in-person licensees for September.

Plainridge is taxed on 48% of its gross gaming revenue. Of that amount, 82% is paid to local aid and 18% is allotted to the Race Horse Development Fund. MGM Springfield and Encore Boston Harbor are taxed on 25% of gross gaming revenue.

That cash is allocated to several specific state funds as determined by the gaming statute.
