How our experts rate Massachusetts Sportsbook promos

Our experts have power-rated the top Massachusetts sports betting promo codes in the order you’ll discover below. The biggest variable for each sportsbook is the value of its welcome offer.

Other considerations included user experience and the ease of claiming the bonus using a Massachusetts sportsbook promo code.

BetMGM Massachusetts Bonus Code

BetMGM sports betting promo code

Without a doubt, BetMGM Sportsbook provides the best sportsbook bonus offer for Massachusetts residents. There’s no competition for the top spot as of now. By using the bonus code THELINES, first-time customers will reel in $1,500 in bonus bets if your first wager at BetMGM doesn’t cash in.

BetMGM Massachusetts initially went live in March 2023, right before the NCAA tournament.

Additionally, BetMGM Massachusetts separates itself from the rest of the pack with its tokens and early payouts. Whether you’re a new user or have been wagering at BetMGM Sportsbook for two years, the operator offers a 25% odds boost for any PGA Tour event. An example of early payouts is if you bet on the Red Sox before they lead by two runs in the early goings. In this case, you would win your bet without sweating out the remainder of the game.

FanDuel Massachusetts Bonus Code

FanDuel sports betting promo code

FanDuel is one of the country’s most reliable sports betting brands. The $300 bonus offer is a big reason why.

Their regular Dinger Tuesdays promo is among the best sports betting promos for new and old customers, to boot. With this weekly offer, customers will receive $5 in bonus bets for every home run hit. That includes wagers on Red Sox stars Jarren Duran and Rafael Devers.

For FanDuel, no Massachusetts sportsbook promo code is needed.

Caesars Massachusetts Promo Code

Caesars sports betting promo code

Even though Caesars Sportsbook isn’t at the top of the board, it’s still a top-tier Massachusetts sportsbook. Caesars Massachusetts’ bonus code will grant customers $1,000 in bonus bets if their first wager at Caesars loses.

Get started with the Massachusetts sports betting promo code of THELINES1000.

Moreover, Caesars covers you during the “slower” sports months, including weekly MLB and golf betting odds boosts.

Types of sign-up Massachusetts Sportsbook promo codes

It’s important to read the fine print for Massachusetts sports betting promos. The best sports betting sites have “Bet & Get” or “Deposit Match” offers, but customers should understand what they’re signing up for. Here’s the meaning behind bonus offers when using Massachusetts betting promos.

Bet & Get: The “bet and get” offer insinuates that a customer “gets” bonus bets for betting only a minimal amount of cash in his or her sportsbook account.

Bet insurance: Bet insurance is another intriguing promotion from Massachusetts sportsbooks. If you lose a bet, the sportsbook will give you “credit” (i.e. bonus bets) for the amount of your initial wager, usually up to a max amount.

Deposit match: Here, you deposit a certain amount of money in your sportsbook account, and the book will match it without needing a result from any bet. If you fund your Massachusetts sports betting account with $250, this operator will provide you with an extra $250 in bonus bets.

No-deposit promos: This last term applies when you do not have to fund your sportsbook account to earn bonus bets.

Types of Massachusetts sportsbook promos for existing users

Massachusetts sports betting promos are typically available to new and returning Massachusetts sportsbook users.

Bonus Bets: This term has been discussed throughout this Massachusetts sports betting guide. It refers to a set amount of money to bet as promotional credit, and that credit can’t be redeemable in cash. If you wager $5 in bonus bets and the profit churns out to $5, you’ll be up $5 in real money.

Parlay Insurance: Although parlays are appealing on the surface because of their potentially big odds, they require users to predict multiple outcomes correctly. Parlay insurance is here to help, allowing users to receive a refund in bonus bets if only one leg of the parlay is incorrect.

Reload Bonuses: A customer reels in bonus bets after funding his or her sportsbook account with more money.

Profit Boosts: An increase in the money you will net on a winning wager. These boosts will normally come in a 25%, 33%, and 50% profit boost.
