Massachusetts officially legalized sports betting in August 2022 when then-Governor Charlie Baker signed House Bill No. 5164 into law.

Today, there are a total of seven (7) legal sports betting apps in the state of Massachusetts, and more are expected to launch in the near future. And the best part? Each platform is currently providing a huge welcome bonus to help you get started.

How We Rank the Best Online Sports Betting Bonuses

One of our main goals here at ATS.io is to provide our readers with the best sportsbook bonuses that their state has to offer. As a result, when evaluating Massachusetts sports betting promos, we always make sure to take the following factors into account:

• Bonus Amount: The size of the bonus offered by a sportsbook is a key factor in our ranking process. We typically assess the generosity of the bonus in terms of its maximum value. For example, a $500 deposit match would be more appealing than a $100 deposit match.
• Wagering Requirements: We also consider the terms and conditions attached to each bonus, paying close attention to the wagering requirements. High wagering requirements can diminish the value of a bonus, so we prioritize offers with reasonable playthrough conditions.
• Duration and Expiry: Some bonuses may have time limitations or expiration dates attached to them. As a result, our team factors in the duration of the bonus offer and its expiry conditions to assess its overall value to bettors.
• Reputation and Trustworthiness: Furthermore, we only recommend bonuses from reputable and trustworthy sportsbooks that have a track record of fair and transparent dealings with their customers. The reputation of the sportsbook plays a significant role in our ranking process.
• Additional Promotions: Beyond the initial bonus offer, we also consider the availability of ongoing promotions and rewards programs. Sportsbooks that provide regular bonuses and incentives for their customers rank higher in our evaluation.

How Do Massachusetts Sportsbook Promos Work?

So, how do sportsbook bonuses work in Massachusetts? Well, it depends on the type of offer you're dealing with. Here are a few of the most common types of sign-up bonuses at MA online sportsbooks as well as a quick explanation of how they work:

Deposit Match Bonuses

With deposit-match bonuses, the sportsbook matches a percentage of your initial deposit up to a certain amount. For example, if you deposit $500 and the sportsbook offers a 100% deposit match up to $500, you'll receive an additional $500 in bonus funds, giving you a total of $1,000 to wager with.

It's also important to note that these bonuses typically come with wagering requirements, meaning you'll need to bet a certain amount before you can withdraw any winnings.

Second Chance Bets

Second-chance bets are promotions that refund your stake if your first bet loses, up to a certain amount. For instance, if you place a $100 bet on a game and it loses, the sportsbook will give you a $100 bonus bet to use on another wager.

This type of offer provides a safety net for new bettors, giving them another opportunity to win without risking additional funds!

Bet & Get Offers

Lastly, Bet & Get promotions are quite popular among Massachusetts sportsbooks these days. They typically work by requiring you to place a qualifying bet to receive a bonus bet or bet credits.

For example, a sports betting app might offer a promotion where if you sign up and bet $5 on any game, you'll instantly receive $100 in bonus bets regardless of the outcome.

New bettors typically love these types of Massachusetts sportsbook promos because they have a low initial investment requirement and offer a significant boost to their bankroll!

Massachusetts Sportsbook Bonus Terms To Know

Before we go any further, let's take a quick look at some of the most important terms to know when it comes to Massachusetts sports betting promotions:

• Wagering Requirements: These are conditions set by the sportsbook that specify the amount of money a bettor must wager before they can withdraw any winnings earned from a bonus or promotion. For example, if a sportsbook offers a $100 bonus with a 5x wagering requirement, the bettor would need to wager $500 ($100 x 5) before they can withdraw any winnings.
• Minimum Odds Requirement: Some sportsbook promotions may require bets to be placed on selections with minimum odds in order to qualify for the promotion. This requirement ensures that bettors don't exploit the promotion by placing bets with very low odds.
• Maximum Bet Limit: The maximum bet limit is the highest amount that a bettor can stake on a single bet when using a particular promotion or bonus offer. Sportsbooks may impose maximum bet limits to manage their risk exposure or to prevent abuse of the promotion.
• Qualifying Bet: A qualifying bet is a bet that must be placed in order to be eligible for a specific promotion or bonus offer. The terms and conditions of the promotion will outline the requirements for a bet to qualify, such as minimum stake or minimum odds.
• Promotion Period: The promotion period refers to the timeframe during which a particular promotion or bonus offer is valid. Sportsbooks specify the start and end dates of the promotion period, and any qualifying bets or actions must be made within this timeframe to be eligible for the promotion.
• Restricted Markets: Restricted markets are specific sports events, leagues, or outcomes on which the sportsbook does not allow bets to be placed using certain promotions or bonus offers.
