Massachusetts Sportsbooks Promo Sign-Up Guide

Mar 10, 2023 - 8:20 PM

We finally made it folks. Massachusetts officially goes LIVE Friday (3/10/2023) in the mobile sports betting space, and I couldn’t be more excited. With the college basketball tournament, NBA and the 2023 NFL Draft quickly approaching, there’s no shortage of action for new bettors in the Bay State looking to dip their toes into the fun.

And there’s no better way to start (or continue) your career as a sports bettor than by taking advantage of several promotional sign-up offers provided by the sportsbooks.

I’ve listed out the sportsbooks available to new users based in Massachusetts that go live on Friday 3/10/2023. Catch you on the betting streets!

Sports Betting Advice and Tools

What is a Moneyline Bet?
The Moneyline is a wager option where sports bettors are betting on who will win the game, with the favored team seeing reduced odds and the underdog receiving increased odds. When it comes to football, the spread is generally the primary betting option for most sports bettors. It’s a little more straightforward in that your win amount is generally the same regardless of which side you pick. However, with the moneyline, you can see a favorite at -130 while the underdog is at +110. This discrepancy is where you can find hidden value as a sports bettor. For more on moneyline wagers, see the BettingPros Sports Betting 101 Moneyline Bet video.
