The Massachusetts Expand Slot Machine Gaming Initiative was a 2016 Massachusetts ballot measure.

Also known as Question 1, it was an indirect initiated state statute question that would allow the Massachusetts Gaming Commission to issue an additional license for another slot machine parlor to exist in the state.

The referendum question said that the extra slots parlor could only be permitted on a site that was at least 4 acres (1.6 ha) in size and located within 1,500 feet (460 m) of a racecourse.

[3] The measure was not approved, voting was 57% "no", 37% "yes", and 6% left blank.
