Massachusetts allows for one slot parlor, which is Plainridge Park Casino, as well as three full casinos, two of which have been built: MGM Springfield and Encore Boston Harbor.

As part of trying to surface overall trends in slot payback in various markets where reporting is available, today I take a look at the slot machine payback for the three casinos in Masschusetts.
