Connecticut Governor Ned Lamont agreed the amended compacts with the Mashantucket Pequot and Mohegan tribes in March this year as part of an effort to legalise sports betting and online casino across the state.
In May, Lamont signed off on a bill to legalise online sports wagering, fantasy sports and other forms of igaming.
The bill formalised the compacts and will allow the tribes to offer sports betting online and at land-based sportsbooks at the casinos they operate. The tribes will also be able to offer igaming and fantasy sports competitions, with each tribe permitted to operate one skin for online sports betting and another for igaming.
