Five top Massachusetts sports betting apps recently launched in the state, and if you use the bonus codes listed below, you can bet on all of these great sportsbooks right now.

Best Massachusetts March Madness Promos

BetMGM Massachusetts Bonus Code

Sign up for a new account using the BetMGM Massachusetts sports betting promo code BOOKIESMARCH and get $200 in Bonus Bets Instantly when you make a $10 pre-game moneyline wager on any team. This deal will run throughout the tournament. Here's how it works:

1. Sign up with the BetMGM bonus code BOOKIESMARCH
2. Bet at least $10 on any team in the March Madness bracket
3. Get $200 in Bonus Bets Instantly

BetMGM March Madness Betting Promo Terms & Conditions

• Bet at least $10 on any pre-game moneyline
• Get 4 $50 bonus bets (credited generally with 24 hours)
• Bonus bets can only be placed as a single bet (straight bet, parlay etc)
• You have 7 days to use the bonus bets
• Bonus bets have no cash value
• Any winning from bonus bets is immediately withdrawable

If you don't want that offer, you can use the BetMGM bonus code BOOKIES and get a first-bet bonus up to $1,000 (you can't combine the offers). This means that players can choose from any set of odds in any sports betting market and place a real-money wager up to $1,000 on its outcome—and then earn either cash profit on a winning bet or receive bonus bets that equal their original wager if it loses. 

For example, bettors who lose a $700 real-money wager will be awarded five $140 bonus bets for a second chance to get their bets correct. Note that losing bettors will receive a single matching bonus bet if their first wager is less than $50, but that’s still a great deal for bettors looking for some insurance on the first bet they make at BetMGM.
