New legislation was passed in August 2022 to legalize sports betting in Massachusetts. The Bay State has joined the growing list of US states to allow sports betting, meaning anyone aged 21 or older can now place real money wagers on a variety of different sports.

The state of Massachusetts has been heading toward legal betting for some time. The first senate hearings on the matter took place back in 2017, but it’s taken a number of years for the legislation to be fully worked out and signed into law.

While the new sports betting laws allow freedom for betting on all professional sports, there are restrictions on college sports. Those in MA won’t be able to bet on any college games involving any Massachusetts colleges.

While the law was established in August 2022, the launch of sportsbooks has taken longer to process. The MA Gaming Commission still needs to approve licenses. Full online and in-person betting is expected to go live in 2023, with the first online sportsbooks launching in March 2023.

Boston Celtics Betting Bonuses

With online sportsbooks now live in MA, sports fans are already signing up in droves. Aside from being able to bet on the Celtics, many fans are attracted to the betting bonuses on offer. Because there´s so much competition between sites, most sportsbooks advertise themselves through these special offers.

There are loads of great bonuses available at Boston sportsbooks, all of which allow you to get more value out of your bets. According to our research, these are some of the most popular betting bonuses on offer:

  • Risk-free bets – With a risk-free bet, you don’t need to worry about the outcome, as there’s no way to lose. Many sportsbooks offer risk-free bets, which will refund your stake up to a certain amount if your bet isn’t successful.
  • Matched deposit bonuses – You can claim matched deposit bonuses simply by signing up and making a deposit. These are commonly found online and help you increase the funds you have available to bet with. Your deposit will be matched up to a set amount.
  • Free bets/bet credits – Free bets of bet credits let you place bets for free. You don’t need any funds in your account to use a free bet, and if you lose, then you don’t lose any real money. If you win with the free bet, you’ll receive the winnings but not the free bet back.
  • Odds boosts – Bigger odds mean bigger potential winnings. With an odds boost, you can move the line in your favor, adding a boost to any potential profit you make. These are easy to use and help you find the best value.
  • Loyalty rewards – Many Celtics sportsbooks offer loyalty rewards, which give you special bonuses just for betting regularly. The more you bet, the bigger and more valuable your rewards will be. These include things like bigger withdrawal limits, exclusive promos, and more.

How to Get the Best Lines on the Boston Celtics

When it comes to betting on the Celtics, you want to always look for the best lines if you want to maximize your potential profits. Here are some tips for finding the best lines when betting on the Boston Celtics and NBA games:

  • Compare different sportsbooks – Lines can vary quite a lot between sportsbooks. If you want to find odds that are in your favor, you need to compare different books before you place your bet. Remember that better lines will improve your chance of winning or increase your winnings, and you’ll get the best odds at our recommended sportsbooks.
  • Bet early – Based on our research, betting early has the best chance of finding value. The odds on NBA games are released on the morning of the game, meaning you need to be ready early. As the day goes on, injury news and other factors can influence the lines, but you’ll be better placed to take advantage of this movement.
  • Use live betting – Live betting lets you bet on the Celtics when the game is in-play. The lines can move a lot during a game as momentum shifts, and the score changes, which we’ve found is an excellent opportunity to find value. Make the most of rotations and injuries to find value, and bet during breaks in the game to give yourself enough time.
