Massachusetts Sportsbook Bonuses Explained

Here are details on the offers listed above:

DraftKings MA Sportsbook Promo: $1,250 in Bonuses

Fun fact: DraftKings is based in Boston, so it’s only fitting that you take advantage of the promos your hometown book has to offer.

DraftKings is the only sportsbook in Massachusetts that’s giving out more than one bonus to its new users. To be precise, it’s handing out three, which total $1,250.

The first two – a $50 bonus bet and a 20% deposit match bonus up to $1,000 – are the sportsbook’s standard welcome promos, while the third one is $200 in bonus bets after you place a single $5 wager.

With the $50 bonus bet, all it takes is clicking here to create your account. Once completed, you’ll see a fresh $50 bonus bet ready for use. You can use it on any of Saturday’s or Sunday’s conference tournament games, or on the national tournament starting Thursday.

There’s also the 20% deposit match bonus worth up to $1,000. Here’s how it works: DraftKings MA will hand you an extra 20% off your first deposit. So if you put $5,000 into your account, you’ll receive an extra one grand. Smaller deposits work just fine as well. If you deposit 500, you’ll get a $100 bonus. This deposit match comes with 25x playthrough requirement, which means for every $1 of the match you would like to withdraw, you must wager $25.

Lastly, new users can pocket $200 in bonus bets instantly just by wagering $5. Place any $5 bet, and the sportsbook will send you a $200 cash bonus on the spot. Normally, your first wager under DraftKings’ “Bet 5, Get $200” promo has to settle as a win for you to collect the bonus credits. But for Massachusetts players, you get the money, win or lose.

BetMGM Mass Sportsbook Bonus: $1,000 First Bet

BetMGM – the self-proclaimed “The King of Sportsbooks” – has set up shop in the Bay State and is giving its new users a second chance at winning big. The sportsbook will cover your entire First Bet, up to one grand.

Let’s say you’re really feeling the UCLA Bruins on Sunday and you put a wager of $1,000 on them to win their matchup. Normally, a loss would mean you lose the money entirely. However, when you sign up using the bonus code ‘TODAY,’ you get paid the money back in Bonus Bets.

If your first bet is more than $50 and it loses, you’ll receive five Bonus Bets, each worth 20% of the original stake. If your first wager is for $50 or less, you’ll receive one Bonus Bet, equal to the stake.

Caesars Mass Sportsbook Bonus: $1,500 Bet on the House

Massachusetts players should also check out Caesars and its $1,500 promo. It’s similar to BetMGM’s offer, except that it’s worth $500 more and it’s returned to you as a single Bonus Bet. Caesars will cover your first bet up to $1,500. If you lose, you get it back as a Bonus Bets.

Simply sign up for an account using promo code “TODAY1BET,” and the sportsbook give you credit for this $1,500 wager on Caesars. Use it on any betting line in March Madness, and the sportsbook will cover it entirely.

WynnBet Mass Sportsbook Bonus: Bet $100, Earn $100 Automatically

When you sign up with WynnBET Mass and place a wager at -120 odds or greater (for example, -110 or +125), the sportsbook will prime your account with $100 in betting credits.

This is another great way to build your betting bankroll in time for the NCAA Tournament.
