Massachusetts Sports Betting Bonuses for March Madness: Score $3,750 in Promos

At the conclusion of round one of March Madness, there were zero perfect brackets remaining out of more than 20 million. That’s how exciting and unpredictable this tournament has been. If you’re in Massachusetts, you don’t want to miss out on another round before getting in on the action. Fortunately, residents of the Bay State have a plethora of Massachusetts Betting Bonuses to choose from.

Online sports betting has been legal for a little over a week now, and many of the promos may change at the end of the month. We consolidated the current offer details in the state to make selecting your favorite much easier. Check below to see what is available to you.

DraftKings Massachusetts Promo Code: Score up to $1,250 in Bonuses

DraftKings Sportsbook makes sure new users receive a bonus for signing up. Some of the promo offers, although valuable, are dependent on whether your first wager wins. With DraftKings, you’ll walk away with a minimum of $250 in bonus bets. Here is how the sportsbook’s offer works.

$50 Bonus Bet + 20% Deposit Bonus up to $1,000

You will receive a $50 bonus bet instantly when you make your first deposit. This step is required to complete the registration process, and it takes no more than $10. You will be able to use the bonus bet on any March Madness contest you like, and it will be available to bet with as soon as you receive it.

However, it’s important to put consideration into just how much your first deposit is because DraftKings is matching it at 20% up to $1,000. That means if you deposit $800 when you create your account, you will receive an additional $160 in bonus bet credits.

Bet $5 and Get $200 Instantly

Once you are signed up and ready to wager, place a $5 or more bet on any March Madness betting line, and DraftKings will credit your account another $200 in bonus bet credits. The credits are not dependent on whether the bet wins or not, so you will receive them immediately after submitting the wager. They will be applied to your account in eight $25 bonus bets that you can use on any wagers you choose. 

BetMGM Massachusetts Bonus Code ROCKYBET: Land a $1,000 First Bet

The BetMGM bonus code ROCKYBET doesn’t guarantee a bonus, but it does allow you to take more of a chance with your first wager for a potentially bigger payout. If your first bet loses, you will get it back in the form of a bonus bet with the sportsbook to make another wager. That’s two attempts to earn a nice payout. 

Although March Madness is center stage at the moment, it’s important to think past the big tournament when selecting a potential long-term sportsbook for your sports betting activities. One thing that separates BetMGM Sportsbook is how many sports it has to wager on. From handball to water polo and ski jumping, the sportsbook has options that separate it from the competition.

Caesars Massachusetts Promo Code START1BET: Claim a $1,500 First Bet

The Manning brothers and J.B. Smooth helped launch Caesars Sportsbook into the mainstream just a few short years ago with some pretty memorable commercials. Now, the sportsbook’s biggest weapon is offering some of the most lucrative promos on the market. Currently, new users in Massachusetts who sign up with the Caesars Sportsbook Massachusetts promo code START1BET will land a $1,500 first bet on Caesars.

Like the other similar offers, that means you will get your first wager total back in the form of a bonus bet with the sportsbook. Could you imagine if you placed a $1,500 underdog wager and won because you knew you had a second chance? That’s what these types of offers bring to the table. If you see the next big upset in the tournament on the horizon, this may be the best sign-up bonus for you.
