A new era of legal online sports betting began when a range of high-profile Massachusetts sportsbook apps and sports betting bonuses went live on Friday, just in time for Selection Sunday and the NCAA Tournament.

Retail sportsbooks opened for business back in January, allowing sports fans in the Bay State to place legal wagers for the first time. However, it is a lot quicker and more convenient to use a mobile app, and you now have a wide variety of exciting options at your disposal.

Read on to discover the best Massachusetts sports betting apps and Massachusetts sports betting bonuses. You can download as many of these apps as you like, which will entitle you to all the best Massachusetts sportsbook promos.

BetMGM Massachusetts Betting App & Bonus Code


BetMGM unveiled a plus retail sports betting lounge at MGM Springfield in January, featuring a 45-foot LED screen and four betting windows. It has now rolled out its world-class sports betting app, which you can download via the App Store or Google Play today. This app allows you to bet on more than 20 sports from anywhere in the Bay State, with competitive lines and odds on a vast array of betting markets.

It is a very impressive, sophisticated mobile betting platform, offering more features than rival Massachusetts sports betting apps. You can stream live NBA, MLB and NHL games on your mobile device within the BetMGM app, and it also offers detailed stats and a variety of tools to help you easily compile bets such as parlays and one game parlays.

The BetMGM Massachusetts bonus code MCBET earns you a first-bet offer worth up to $1,000 if you sign up today. You will also receive weekly and recurring promotions, along with MGM Rewards points at this legal, licensed MA sports betting app.

Caesars Sportsbook Massachusetts App & Promo


Caesars Sportsbook is a new Massachusetts betting app that offers a large sign-up bonus, lots of odds boosts and a great rewards program. It is the mobile betting arm of Las Vegas-based casino company Caesars Entertainment, which purchased William Hill in 2021 for $4 billion. It rebranded the William Hill US app as Caesars Sportsbook, and it is now one of the top four sports betting apps in the country.

The team at Caesars Digital has made several improvements to the app over the past few years. It notably added a “Watch and Bet” feature a few months ago, which allows customers to stream select NFL games via the Caesars Sportsbook app. It does not have as many features as the BetMGM app, but it is very quick, agile and accessible.

The Caesars Sportsbook Massachusetts promo code MC1BET earns new customers a welcome bonus worth up to $1,500. You can bet up to $1,500 on any sport, and you will get the money back as a bet credit if your wager loses. Customers can also claim hundreds of odds boosts throughout the week at Caesars Sportsbook, while it offers profit boosts, bonus bets and other deals too.

DraftKings Massachusetts Sportsbook App & Bonus


DraftKings is a Boston-based company that has run Daily Fantasy Sports contests in its home state for many years. It was one of the first Massachusetts betting apps to go live on Friday morning, and it is determined to emerge as the market leader in the Bay State.

To that end, it has rolled out an appealing DraftKings promo code offer, which provides new customers with a “Bet $5, Get $200” deal. Just bet $5 on any pre-game moneyline – you can bet on heavy favorites – and you will receive eight $25 bonus bets no matter how your first bet turns out. There are various additional promos to claim, and you can compete in daily free-to-enter pools in a bid to win bonus bets too.

DraftKings often publishes lines before rival sportsbook apps, and its odds are competitive. It has a huge choice of props and futures markets to choose from, and the mobile user interface is very stylish and easy to browse.

WynnBET Massachusetts Betting App & Promo

WynnBET also opened the doors to an exciting retail sportsbook at Encore Boston Harbor in January. It added a beginner-friendly mobile app on Friday morning, allowing users to bet on football, basketball, baseball, hockey, UFC, boxing, golf, tennis, soccer and motorsports from anywhere in the state.

Most Massachusetts betting apps feature around 20 sports, whereas only 10 are covered at WynnBET MA. That makes it unsuitable for fans of table tennis, volleyball, cricket or Aussie Rules, but it is perfect for betting on the most popular sporting events in the United States. This app offers better odds than most rivals – especially on Tuesdays and Thursdays, when the Wynn Hour promo runs – and it is also more accessible for newcomers to sports betting.

The WynnBET Massachusetts promo code XMCCBET is a “Bet $100, Get $100” sign-up bonus. To qualify, just click through to the site using the link we have provided. Sign up for an account, make a deposit, download the app and sign in. You can then bet $100 at minimum odds of -150 on any game, and you will get a $100 bonus bet as a reward. There are lots of additional ways to earn bonus bets each week too.

FanDuel Massachusetts Sportsbook App & Bonus

Any guide to the top Massachusetts betting apps would be incomplete without mentioning FanDuel, which is the most popular online sportsbook in America. It is another very impressive sports betting app, with no discernible weaknesses. That has helped it achieve an average user rating of 4.8 out of 5 on the App Store and 4.7 on Google Play, having received more than 1 million reviews.

FanDuel also started out as a DFS site, before expanding into sports betting in 2018. Flutter Entertainment – the world’s largest online gambling operator, which also owns PokerStars – has a controlling stake in FanDuel. It has poured its expertise into FanDuel Sportsbook, which offers a very fast, ultra-reliable and accessible app, replete with features such as live MLB and NHL streaming and loads of betting options.

The FanDuel promo code for Massachusetts earns new customers a “Bet $5, Get $200” welcome bonus. You simply need to click the link we have provided, sign up and place a $5 qualifying bet to unlock $200 in bonus credits (which can be broken up however you choose). They have just a 1x rollover requirement as well.

Responsible Gambling

Always gamble responsibly. All licensed and legal operators in the United States have resources available to bettors, including educational guides on how to spot problem gaming, links to support services and tools to self-exclude for a set period of time. Support is available at the National Council on Problem Gaming, 1-800-GAMBLER and American Addiction Centers. Be sure to only wager on gambling sites that are licensed and regulated by the gaming regulatory body in your state. That ensures games are fair, bets are honored, customers’ funds are secure and that there are legal protections for the consumer.

Sports betting and gambling are not legal in all locations. Be sure to comply with laws applicable where you reside.
