Ease of Use
Seconds matter, especially if you're live betting. FanDuel's easy deposits, quick navigation and instant withdrawals make it the easiest to use betting app. If anything, sign-up to use its live betting feature and you'll have the best chance to catch a good line.
Image
Promo Offers
While their casino free-spins are inconsistent, their sports betting profit boosts and no sweat parlays are as competitive as they come. The wide variety of game to game offers guarantees that they have a boost that your current book doesn't.
Image
Referral Bonus
What better way to make some extra bonus money, than by connecting with your friends, and FanDuel offers a great referral bonus. If you open an account and like what you seeing, telling your friends is a win-win.

BetMGM promo code

BetMGM’s physical presence in Massachusetts has helped the gaming giant establish a strong foothold in the state. You’ll find virtually every sport and bet type that you could ask for, as well as one of the industry’s best rewards programs.

When you sign up at BetMGM and claim the offer, you’ll get two bonuses after placing a $10 bet. You’ll get $100 in bonus bets plus a $150 casino bonus. Once the bonuses are credited to your account, you have seven days to use them before they expire.

Promotion Variety
Hopefully you haven't been too distracted by the twinkle in Jamie Foxx's eye, because the offers he is promoting for BetMGM are some of the best out there. Bonus Bet offers like a second chance offer on your first scorer bet make BetMGM a cut above the rest.
Image
Responsible Gambling
BetMGM have put an emphasis on the entertainment element of their product. To ensure it stays entertaining, and in line with their mission to "Focus on What Matters", they have a number of protections in place to ensure everyone has a safe and responsible approach, top of mind.
Image
Location Services
Even the top brands seem to struggle determining a user's location. With the variation in regulation from state to state, that can be really frustrating for people who live near a state-line or bet while they travel. BetMGM does not seem to have that same struggle. Maybe it's because of their association with the resort and travel industry, but they make it very easy to bet on the go.

Caesars promo code

The Caesars brand name is recognized from coast to coast, and the sportsbook has become a popular destination for Massachusetts sports bettors. Regular promos and odds boosts are a hallmark, as is its loyalty program where you can rack up perks based on your play.

You can get started at Caesars with a welcome offer that gives you a chance to continue boosting your winnings. After you place a simple $1 bet, you’ll receive 10 100% profit boost tokens, max winnings of $2,500, which can be used over the next 14 days.

Key features of the current Caesars Massachusetts promo:

Deposit $10 and place a bet of $1 to qualify.
Get back 10 100% profit boost tokens for doing so.
You’ll have the chance to double your winnings.

Caesars Rewards
Whether you live near a Caesars casino location or not, Caesars Rewards is one of the best rewards programs out there (including that BS your credit card company offers you). Our take - if you're betting somewhere anyway, why not earn benefits like early-access to concert tickets, VIP Travel Lounge access and top restaurant gift cards.
Image
Profit Boosts
Caesars extensive history in the Vegas industry means they can offer some of the most unique profit boosts you can't find at other sportsbooks. Vegas Grand Prix, the biggest Vegas UFC events, NBA Cup in Vegas will all be boosted at Caesars.
Image
Sports Variety
Of the major players in the US sports betting industry, Caesars has the widest variety of sports available to bet. Yes, we all love to bet on the sports we know, but if you're really trying to make some money it's the obscure sports that provide the most opportunity. The Vegas traders that work for these big books know NFL, NCAAF, etc., but are you confident they know Aussie Rules football? Sign up and find out!

types of sportsbook promos

A sportsbook promo is designed to attract new players. The best sportsbooks also take care of their existing players with a range of incentives. Here are some of the most common bonuses and promos you’ll come across at Massachusetts sportsbooks.

welcome promo
The top sportsbooks offer sign-up bonuses for new players to claim. Types and the amount of offers will vary. You can find details on the latest promos from the best Massachusetts sportsbooks on this page.
deposit match
For this promo, the sportsbook will provide you with a match of your deposit. It could be for a certain percentage, such as 50% up to $100, or a straight-up match up to $50 or more.
no sweat bet
This can go by different names, including “first bet insurance” or a “second chance” bet. In a nutshell, you have some protection for the first wager you place. If you lose, you get back your stake as bonus bets, up to the max of the offer
bet to get
For this bonus, you bet a certain amount, such as $5, to get back bonus bet credits, like $150. Watch the terms on this one, as some will require you to win to get the bonus, while others will give you the credit, win or lose.
odds boost
Sportsbooks will regularly boost the odds on select wagers, such as a moneyline, player prop over/under, or a same game parlay wager. When the odds are boosted, you have the potential to win more when compared to betting at the listed line.
referral bonus
Some operators have refer-a-friend bonus offers. If one of your referrals signs up and makes a deposit, there could be something in it for you in the form of a bonus bet or other promo offer.
reload bonus
From time to time, you may receive an incentive offer to reload your account. It could be a match of your deposit up to a certain amount, such as $25, or a percentage bonus on your next deposit, like 50%.
loyalty program
Players can join the rewards program at select sportsbooks and receive perks based on their play, such as bonus bets or entertainment discounts. Caesars and BetMGM offer rewards programs for Massachusetts players.

Legal sports betting in Massachusetts has been a massive hit since its debut in 2023. Sportsbooks in the state continue to go out of their way to attract players. That’s a big plus for bettors, as the result is a steady stream of new sportsbook promos to consider.

Image
User Experience: We are looking for sportsbook promos that make the betting process seamless. If we have a hunch on a game, we want the odds for that game at our fingertips. Easy-to-access Bet Slips, intuitive Parlay Features, and a detailed Betting History, are just a few of the user experience criteria our experts require from a top sports betting app.
Image
Bonus Availability: We look for sportsbooks that offer real value in their customer deals. Not some snazzy marketing lingo, but real dollars available for you to collect. From killer welcome bonuses and promo codes with realistic conditions, to lucrative everyday customer offers, Bet Boosts, rebates, and VIP programs. Sportsbooks must offer something we can understand and can reasonably collect upon, or we won't recommend them to you.
Image
Payment Process: We all want to be able to fully realize our winnings and take our money home. Too many sportsbooks make it so difficult to withdraw your funds, that you are forced to bet again, seemingly indefinitely. At Odds Shark, we only recommend betting apps that our experts are comfortable holding their own bankroll. The best sportsbooks in the United States offer a variety of reliable deposit methods with reasonable payout speeds, so that you aren't the friend that can't buy dinner because "all my money is in my betting account".
Image
Sport Odds Variety: We champion sites that provide extensive odds across a huge range of global sports. Sportsbooks must prove they are ready to promote big events properly. It isn't going to matter whether a betting site has Korean Baseball odds, if they can't get the Super Bowl right, but we know the way those popular betting markets are juiced. Every now and then, our Odds Shark handicappers have a gut-feeling on a European Handball match at 5am on a Wednesday. We want a sportsbook that lets us ride that out with them.
Image
Safety & Security: Odds Shark takes player safety very seriously. We only recommend betting sites that match our high degree of safety and security standards. That means a site must operate 256-bit SSL or TLS encryption as standard. They also need to provide fair, transparent Terms & Conditions for all players.
