Wynn and Mohegan Sun have responded to a series of terms and conditions state gambling regulators seek to impose should either casino plan win the Boston-area casino license.

Mohegan Sun, in a letter released Monday, said it has secured $100 million more in equity for its proposed casino at the Suffolk Downs horse racing track in Revere, as the commission requested.

But it declined to market the Revere casino in Connecticut, where its flagship casino is located. Instead, Mohegan Sun proposes expanding those efforts to Maine and to honor any gambling promotions from its other casino properties at the Revere resort.

Wynn, meanwhile, rebuffed the panel's request to re-design its soaring glass hotel tower. It did, however, submit a revised plan to pay for area traffic improvements, especially in nearby Sullivan Square.
