Massachusetts would prohibit people under the age of 21 from playing paid fantasy sports games under a proposed set of regulations for the fast-growing, multibillion-dollar industry laid out on Thursday by state Attorney General Maura Healey.
The proposals would also prohibit professional athletes, agents and others connected to pro sports from taking part in paid fantasy contests related to their sports and ban promotions of paid fantasy sports on college campuses.
The fantasy sports business, led by DraftKings and FanDuel, has drawn increasing regulatory scrutiny over the past few weeks with state regulatory officials debating whether the paid daily games are gambling.
The approach is a more restrained one than that taken by New York state, whose attorney general on Tuesday sought a court injunction to shut down DraftKings and FanDuel, calling the games "plainly illegal."
Modern fantasy sports started in 1980 and have mushroomed online. Participants typically create teams that span an entire season in professional sports, including American football, baseball, basketball and hockey.
Daily fantasy sports, a turbocharged version of the season-long game, have developed over the past decade. Players draft teams in games played in just one evening or over a weekend.
