BetMGM MA Bonus Code Offers for Massachusetts Users
Massachusetts bettors have two welcome offers to choose from. Both are available exclusively to new BetMGM customers in the state.
| Offer | Code | How It Works |
| $1,500 First Bet Offer | TOPACTION | Place any first bet. If it loses, receive up to $1,500 back in bonus bets |
| 20% Deposit Match up to $1,500 | TOPTAN1500 | Receive 20% of your first deposit as sports bonus, up to $1,500 |
For example, if you use code TOPACTION and place a $200 first bet on the Celtics spread -12.5 (-110) in Game 1 and it loses, BetMGM credits your account with $200 in bonus bets. If it wins, you keep the winnings. Either way, the bonus bet safety net gives Celtics fans a meaningful cushion for one of the biggest games of the year. Bonus bets over $50 are split into five equal tokens and expire seven days after issuance.
