Caesars Sportsbook Massachusetts Promo Code: $1,500 Offer in MA, $1,250 for Other States article feature image

Caesars Mass. Boston-Celtics, 03/12/2023

Today is the day we’ll find out the 68-team field for March Madness, but that shouldn’t detract from the many betting opportunities. New bettors can use the Caesars Sportsbook Massachusetts promo code ACTION41BET for a $1,500 first bet on the house.

This promotion protects you from losing all your money on your first bet. Caesars matches your first bet in bonus bets if you lose. You’ll need to bet $1,500 to earn that amount in bonus bets.

In other legal Caesars states, new users can use the promo code ACTION4FULL for a $1,250 first bet on the house. It’s essentially the same offer, except the maximum you can earn is $250 less.

Betting with the Caesars Sportsbook Promo Code

Before we break down the process of using bonus bets, we have to bet on a sporting event at Caesars Sportsbook.

We have the NBA, NHL, MLB, college basketball, and more. Let’s go with Sunday’s night matchup between the Knicks and the Lakers. The Knicks have been the better team, but how will they fare on the road?

Let’s say the Knicks have +120 odds to win Sunday’s game. What happens if we deposit and bet $100 on the Knicks moneyline?

  • New York Knicks Win: Earn $120 in winnings and keep your $100 wager.
  • New York Knicks Lose: Your $100 turns into bonus bets.

Caesars Sportsbook Bonus Bets 

Learning about bonus bets is important because they aren’t the same as withdrawable cash. Bettors only keep the winnings when using bonus bets instead of the winnings and initial deposit.

We always recommend using bonus bets on a plus-money prop or longshot. This gives you the best chance to maximize your profit.

It only makes sense for Massachusetts bettors to wager on a local team. Let’s use our $100 bonus bets to wager on the Celtics’ winning the NBA Finals at +325.

  • If the Celtics win the NBA Finals, you’ll take home $325. That money is available to withdraw.
  • If the Celtics lose, your $100 bonus bet is gone.

Betting on Massachusetts Sports Teams

Massachusetts bettors have three chances to bet on their team today. Check out the schedule below to see when the Red Sox and Bruins will be in action.

  • Red Sox vs. Orioles: March 12 at 1:05 p.m. ET
  • Yankees vs. Red Sox: March 12 at 1:05 p.m. ET
