Seven mobile sportsbooks apps have been given the green light to start taking bets in time for March Madness.

Mobile betting goes live in the Bay State March 10 — four days before the NCAA tournament is set to roll out.

The mobile apps approved by the Massachusetts Gaming Commission Thursday include: Caesars Sportsbook, BetMGM, WynnBET, Barstool (Penn Interactive), FanDuel, DraftKings, and betr. In total, regulators cleared the way for nine mobile operators,  with two of those, Fanatics and Bally Bet, not planning to go live until May, according to bookies.com.

“We are very confident in that ability to allow the licensees to launch on the 10th that are ready to go,” the commission’s Executive Director Karen Wells said about the March 10 start date for mobile betting.

Sports Wagering Director Bruce Band added, “Everything seems to be moving forward very smoothly … I don’t really see, at this point, any stumbling blocks.”

There was another snag, however with betting on college teams that emerged at the meeting.

Band alerted commissioners that Encore Boston Harbor had recently allowed bets on a Boston College women’s basketball game, which is against the rules in Massachusetts.

Band said the matter is being vetted by the Investigations and Enforcement Bureau and will be before the commission in greater detail “in the coming week or so.”

An Encore spokesperson said, “Through our audits we identified a programming error in the system as it relates to NCAA women’s college basketball markets and are currently working with our provider on a permanent solution. In the interim, we have locked all NCAA women’s college basketball betting.”

Massachusetts law allows bets to be placed on Massachusetts colleges and universities only when the team is playing in a tournament with at least three other participants.

Whether to allow any collegiate betting at all was a major sticking point on Beacon Hill between the House (which wanted all college events open to wagers) and the Senate (which passed a bill prohibiting all college betting) last session. The in-state school exclusion was a key compromise that got the legalization bill done at the last minute.

All three sportsbooks open in Massachusetts — Encore, MGM Springfield and Plainridge Park Casino — are already under Gaming Commission scrutiny for having illegally accepted wagers on regular-season college basketball games that involved Massachusetts schools within the first few days of legal in-person betting.

The commission plans to hold adjudicatory hearings March 14 on the first two violations that came to light, at Encore and Plainridge Park Casino.
