   Also Known As: Deposit Matches.

What Our Experts Say

"What makes Maine sportsbook promos so different is the exclusivity. With just two operators live and tribal partnerships capping expansion, bettors can expect fewer but often more targeted, locally driven offers than in more crowded state markets."

4. When was Sports Betting Legalized in Maine?

Sports betting was legalized in Maine in 2022. The state passed a bill allowing both online and in-person sports betting. Mobile betting apps launched in November 2023.

Since then, residents and visitors of Maine have been able to enjoy the excitement of placing bets on their favorite sports teams and events.

Maine and Legal Online Casinos

A proposal to legalize online casino gaming (previously thought to be off the table) was recently revived by the Veterans and Legal Affairs Committee. This unexpected move could position Maine to join a very select group of U.S. states with legalized iGaming.

At the time of writing, only seven states have authorized online casino platforms: Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, Rhode Island, and West Virginia. The most recent to do so was Rhode Island, which gave iGaming the green light in June 2023. If the bill in Maine progresses further, it could significantly expand the state’s digital gambling market beyond its current sports betting offerings.

While online sportsbooks have already established a presence in the state, the addition of digital table games and slots would bring Maine in line with some of the most progressive gambling frameworks in the country.

5. Who Can Access Maine Sportsbook Promos?

Maine sportsbook promos are accessible to anyone within the state borders. You don't have to be a Maine resident to claim these promos, including the welcome bonus. This rule applies not only to Maine but also to all U.S. states where online sports betting is legal.

As long as you are physically located within Maine or any other legal state, you can access and earn money from these promos.

6. Opting Into Maine Sportsbook Promos

Something many new bettors don’t realize is that not all Maine sportsbook promos are applied automatically. Some online sportsbooks require users to opt in manually before a promo is activated.

This could involve clicking a button in the "Promotions" tab, entering a promo code during registration, or placing a qualifying wager. Missing this step means you won’t receive the advertised bonus — even if you meet all the other conditions.

This is especially important in Maine, where smaller promo windows and localized offers make timing critical. Always double-check the activation steps on any Maine sportsbook before you deposit or place your first bet. It’s a small step, but one that can be the difference between bonus credit and missing out entirely.

7. Which States Close to Maine Offer Sportsbook Promos?

If you're looking for sportsbook promos and you're close to Maine, here are five neighboring states where online sports betting is legal:

1. New Hampshire
2. Massachusetts
3. Connecticut
4. Rhode Island
5. Vermont
   
   

Maine Sportsbook Promos and Physical Location

Like other states' bonus offers, Maine sportsbook promos are linked to geolocation verification.

In order to legally access any Maine sportsbook bonus, you must physically be within the state borders, even if you're eligible elsewhere. This is enforced using geolocation software built into both desktop and mobile sportsbook platforms. Trying to redeem a promo while across the border — even just miles into New Hampshire — will result in immediate access restrictions.

However, you can travel to different states to take advantage of their sportsbook promos, without needing to be a permanent resident.

10. How Do We Rate and Review Maine Promos & Bonuses?

Our team of sports betting experts have racked up decades of experience sourcing and converting sportsbook promos across the US and Europe. Using their industry know-how and the latest promo comparison software, they analyze, rate and rank the top bonuses in each state so you don't have to.

Six of the most important factors they consider when rating promos are:

• Maximum Bonus Value: While higher amounts are appealing, bigger isn't always better, as larger bonuses can be more difficult to obtain.
  
  
• Personal Investment: Most bonuses require a minimum deposit or wager to activate.
  
  
• Ease of Use: In most cases bonuses are pretty easy to claim - often requiring a small deposit to unlock. However, some promos have slightly more complex rules.
  
  
• Play Through Requirements & Odds Restrictions: Typically, bonuses cannot be immediately withdrawn as cash; you must wager the bonus amount a certain number of times first.
  
  
• Bonus Expiry Date: It's important to know how long you have to use the bonus funds and whether that timeframe is sufficient.
  
  
• Additional Perks: Some bonuses include extra rewards points or bonus spins at the sportsbook's casino.

While we'll do everything possible to bring you the best sportsbook promos in Maine every month, it's important to be aware of the potential risks that can come with these bonuses. 

11. Are There Any Risks Attached to Sportsbook Promos in Maine?

While claiming sportsbook promos can be a great way to maximize your betting profits in Maine, it's important to be aware of their potential risks.

Four of the most notable risks attached to promo offers are: 

• No Guaranteed Winnings: Whether it's a $150 free bet, a $1,000 risk-free bet or a 50% deposit bonus, if you place your bonus credit on a losing bet you will still come away with no more cash than when you started.  
  
  
• Risk of Losing Money: One of the most common ways bettors lose money through promos is through risk free bets. Let's say you're gifted a $500 risk-free bet and you place your $500 on the losing side of a game, you won't be refunded with $500 of withdrawable cash, but instead $500 of site credit (often in the form of a free bet). Place this free bet on the losing side and you've just lost $500 to the sportsbook.
  
  
• Limited Number of Sign-Up Bonuses: While sign-up bonuses can be generous, you can only ever receive one sign-up bonus from each sportsbook (when you first create an account). This means that there's only a set number of sign-up bonuses available to each user. As a result, relying purely on these may not be a sustainable long-term plan.
  
  
• Misuse of Promos: Certain promos have more complex rules and often hidden T&Cs. As a result, if you go into them without proper guidance and support you can risk reducing the amount of overall profit you earn, or worse, lose money.

But it isn't all doom and gloom! There is one way you can turn promos into profits...

12. How to Maximize Profit From Sportsbook Promos & Bonuses

While it's true that risks can arise when claiming sportsbook promos, one clever technique exists that can help you bank profits.

Promo conversion (A.K.A matched betting), is a fully legal, super simple (with the right platform) method of turning sportsbook promos into cash.

Simply put, it involves betting on one side of a game to qualify for a sportsbook promo, then betting on the other side to cover both outcomes, so no matter who wins, you win. Repeat this process using your new promo and voila! You've locked in a profit. 

And while this sounds simple on paper, to earn serious monthly profits with this technique you need rapid odds-matching software, an up-to-date promo database and tailored instructions for converting each offer at your disposal. 

That's where we come in.

At ProfitDuel we have over 10 years' experience in the matched betting industry. In that time we've provided the software, strategies and one-to-one support to help 500,000+ members in the US & Europe earn profits each month.
