Massachusetts sports betting got its start at the end of January with retail betting and will now be adding some of the top online sportsbooks in the industry. Here are the three best MA sportsbook promos and how to claim them.

DraftKings Promo Code

All new users who sign up using our DraftKings Massachusetts promo code link below and make an initial deposit of at least $5 can claim up to $1,250 in bonus bets.

The $5 deposit automatically qualifies you for a $50 bonus bet and a 20% deposit match worth up to $1,000.

Users can then place a $5 wager on any pre-game moneyline and receive an additional $200 in bonus bets plus the winnings from your wager. These bonus bets will be split into eight $25 DraftKings Sportsbook site credits.

With the BetMGM Massachusetts Sportsbook promo, your first bet comes with a “safety net” so to speak. All new users who deposit at least $10 and sign up with the BetMGM Massachusetts promo code ROCKYBET will be eligible for the first bet offer.

If the first wager you place with BetMGM settles as a loss, your stake will be matched as a bonus bet with a maximum value of $1,000. You can then use the bonus bet on another wager to win your money back.

If your first bet is worth $49 or less, you’ll receive one bonus bet credit. Wagers over $50 will be broken down into five equal bonus bets.

Caesars MA Promo Code START1BET

The Caesars MA Sportsbook new user offer is essentially the same as the BetMGM offer laid out above. If the first wager you place results in a loss, Caesars will match your stake as a bet credit all the way up to $1,500.

The main difference between the two is Caesars will give you only one bet credit regardless of your first bet amount. Whether your first wager is for $20 or $1,200 if the bet loses you’ll receive one bet credit.
