BOSTON (AP) – Massachusetts gambling regulators are reviewing daily fantasy sports contests that have exploded in popularity in recent years.

The state Gaming Commission meets Thursday to begin considering policy questions they say the governor and legislature will have to decide.

Among them are whether fantasy sports are legal, should they be regulated, who should regulate them and what aspects of the games should be regulated.

Boston-based DraftKings is among the market leaders in daily fantasy sports, in which players pay an entry fee and compete for cash prizes in online contests involving college and professional athletes.

The companies say the games aren’t gambling and are exempt from the federal online gambling prohibition.

The discussion comes as Massachusetts Attorney General Maura Healey has been conducting a review and other states are weighing regulations.
