Top 5 Best Maine Betting Sites in 2025

Maine's digital betting world offers plenty of options for both experienced bettors and newcomers. You'll want to look for reliable platforms with competitive odds and easy-to-use interfaces. Here's my complete analysis of the top five betting sites in Maine in 2025, based on real-world testing and research.

1. BetOnline.ag – Best for app experience

BetOnline has become the first choice for Maine bettors who want a smooth mobile experience. Their mobile platform is a perfect complement to their desktop site, giving users better access to features. The mobile site adapts naturally to any screen size, making it stand out from other betting platforms.

BetOnline really shines with its complete sports coverage. Users can bet on more than 30 different sports, from the major North American leagues like the NFL, NBA, MLB and NHL to global sports. You can also bet on cricket, rugby, darts and many other international competitions.

Key benefits include:

• 21-year-old platform licensed by Panama Gaming Commission
• 5% bonus boost on Bitcoin deposits
• 50% sports welcome bonus for new users
• Round-the-clock support through live chat, email, and phone

BetOnline processes payments faster than most competitors, with all payouts within 24 hours. Tech-savvy Maine bettors love their wide range of cryptocurrency options, including Bitcoin and Ethereum.

2. BetUS – Best for rewards program

BetUS leads the pack with a well thought out rewards program that grows with your deposits. The platform has been operating under a Curaçao eGaming license since 2005 and has built a reputation for reliability.

Their rewards program uses tiers from A to G based on deposit amounts. Tier D ($1,000-$1,999 in deposits) comes with a 125% sign-up bonus, 200% cryptocurrency sign-up bonus, 250% casino sign-up bonus, 30% re-up bonus, and 10% casino chip bonus.

BetUS covers more than 20 sports markets with competitive odds for every major league and event. Maine bettors can place bets from anywhere through their mobile-friendly site without downloading any apps.

BetUS TV differentiates itself by offering sports analysis that helps users create better betting strategies. Active players earn points that can be redeemed for free games, keeping them coming back for more.

3. XBet.ag – Best for international markets

XBet has carved out a niche as the go-to site for Maine bettors seeking international wagering options. Established in 2014 and regulated by the Curacao eGaming Commission, XBet offers a unique mix of international coverage and specialty markets.

A major advantage that XBet has over government-controlled sites is that it operates in an atmosphere of freedom. Being offshore, XBet can operate with lower overhead costs, which translates into better odds and higher payouts for the user. The site is legally accessible in 46 of the US states, but simply unavailable in New York, New Jersey, Pennsylvania and Nevada.

XBet's online sportsbook deserves special mention. With no apps to download, customers get the full sportsbook on their smartphones. Such ease of use, coupled with phenomenally fast payouts, puts XBet squarely in contention with Maine sportsbooks.

The site offers an enticing first deposit bonus of up to $500 with a 100% match upon sign-up. Players must meet a 7x rollover requirement to cash out. XBet also excels at covering niche markets such as table tennis, volleyball and even US politics.

4. SportsBetting.ag – Quickest early lines

For those betting on Maine and looking to beat the market, SportsBetting.ag stands out as the first to regularly publish early betting lines. Founded in 2012 and licensed by Curaçao eGaming, the site has built a reputation for speed and depth of coverage.

SportsBetting.ag offers an unmatched selection of betting options including Sides, Totals, Money Lines, Props and Futures odds. Each sport includes player performance props, so it's especially suited for the stat sheet obsessed bettor.

The site's commitment to in-depth sports coverage is evident in its offerings:

• All North American major sports like baseball, professional and college basketball, football, and hockey
• International sports like cricket, rugby, darts, snooker, and handball
• Soccer lines from over 25 countries with the top European leagues

Live betting has exploded in popularity over the past few years and SportsBetting.ag has risen to the challenge with one of the most diverse live betting schedules around. Their reload bonus program is incredibly generous, offering a 25% match on any deposit made after your first one, up to $250.

Banking options at SportsBetting.ag also include credit cards, bank wire, wire transfer, and more than a dozen of the most popular cryptocurrencies such as Bitcoin, Ethereum, and Dogecoin. Bitcoin withdrawals are available within 24 hours or less, while bank wire withdrawals take 5-7 days.

5. Bovada – Live Betting and Odds Favorites

Bovada has established itself as America's best place for live betting enthusiasts. Founded in 2011 and licensed by Curaçao eGaming, Bovada is known for being trustworthy, easy to use and offering fair odds.

What really sets Bovada apart is its sophisticated live betting platform. Its extensive live betting markets cover the best international events and all major US sports. The platform excels at providing real-time wagering opportunities with extremely competitive odds, especially for underdog bets with its extensive "recreational" player base.

Bovada's sportsbook is actually quite broad, including not only the major US leagues, but also tennis, soccer, UFC, Australian rules football and golf. College athletics is also included in their odds board, though limited compared to other sites.

New members at Bovada can earn a 50% match bonus up to $1,000 in bonus cash. Only a 5x playthrough is required to convert the bonus money into cash, much lower than most other sites offer. Their rewards program also integrates perfectly with this feature, allowing you to earn points for every wager you make.

Is Online Sports Betting Legal in Maine?

Sports betting is fully legal in Maine. The state launched its regulated sports betting market on November 3, 2023. Both online and retail options are available to residents 21 and older. It took the state several years and several legislative attempts to legalize sports betting.

Legalization timeline and key dates

Several key moments shaped Maine's path to legal betting sites:

• May 2018: The U.S. Supreme Court overturned PASPA, which allowed states to legalize sports betting
• June 2019: Maine's legislature passed its first sports betting bill, but Governor Janet Mills vetoed it
• January 10, 2020: Governor Mills formally vetoed the original sports betting legislation
• April 5, 2021: A new sports betting bill passed both legislative chambers before stalling on the appropriations table
• April 19, 2022: The Senate gave approval to Governor Mills' sports betting bill with a 23-11 vote
• May 2, 2022: Governor Mills signed sports betting into law
• July 31, 2022: The sports betting law took effect
• August 2023: Maine's Gambling Control Unit completed the rules for sports betting
• November 3, 2023: Both retail and online sports betting launched officially in Maine

Governor Mills authored the successful legislation (LD 585) herself after vetoing previous attempts. In 2022, Maine became the first state to give its four federally recognized Indian tribes control over mobile sports betting.

Who regulates Maine betting sites?

Maine's Gambling Control Unit (MGCU) oversees all licensed gambling sites. This regulatory agency operates within the Maine Department of Public Safety and performs these key functions:

1. The unit licenses sports wagering facility operators, mobile sports wagering operators, management services, suppliers, and employees
2. Laws and rules about sports wagering get enforced
3. Sports wagering systems and methods need approval
4. State gambling regulations must be followed

Milton Champion is the Executive Director of the Maine Gaming Control Board. He oversees the daily regulation of sports wagering. The MGCU created a complete regulatory framework to launch the state's wagering market.

Licensed betting sites are subject to strict oversight through careful application and approval. Operators pay high licensing fees and undergo detailed background checks. Mobile operators must pay $200,000 for a license, which must be renewed every four years. They also pay a 10% tax on adjusted gross revenues.

Retail vs. online betting options

Maine offers both retail and online sports betting with different structures and availability:

Online Betting:

• Maine's four federally recognized tribes control online betting exclusively: Penobscot Nation, Passamaquoddy Tribe, Houlton Band of Maliseet Indians, and Aroostook Band of Micmac Indians
• Each tribe can work with one commercial sportsbook brand
• DraftKings (with Passamaquoddy Tribe) and Caesars Sportsbook (with three Wabanaki Tribes) are the only active online operators
• About 85% of all Maine's bets happen online
• A $200,000 license fee needs renewal every four years

Retail Betting:

• Commercial tracks, casinos, and off-track betting facilities can offer retail betting
• The state allows up to 10 retail sportsbook locations
• Hollywood Casino (Bangor), Oxford Casino (Oxford), and various OTB locations can offer betting
• Retail licenses cost $4,000 and need renewal every four years
• Only 15% of total betting happens at retail locations
• Oddfellahs by Caesars opened Portland's first retail sportsbook in September 2024

Retail sports betting has grown slowly in Maine since it was legalized in 2022. Oddfellahs, powered by Caesars Sportsbook, opened the state's first in-person betting location in September 2024, nearly a year after online betting began.

Native American tribes operate the lucrative mobile wagering sector. The state's two non-tribal casinos (Penn Entertainment's Hollywood Casino and Churchill Downs' Oxford Casino) can only offer retail sports betting.

How to Choose the Right Maine Betting Site

There are several key factors to consider before choosing the right betting platform. Maine residents can choose between two regulated operators and other offshore options. Let me show you what matters most when choosing between Maine betting sites.

User interface and mobile experience

Your daily betting activity is heavily influenced by the quality of a betting site's mobile experience. DraftKings currently leads the Maine market with stellar mobile app ratings of 4.8/5 on iOS (from 725,000+ reviews) and 4.6/5 on Android (149,000+ reviews). Caesars Sportsbook isn't far behind with solid ratings of 4.6/5 on iOS (66,500+ reviews) and 4.3/5 on Android (25,700+ reviews).

Here's what to look for in mobile interfaces:

• Navigation efficiency: The app should let you switch between sports and markets quickly
• Visual clarity: Clean layouts should not sacrifice readability for looks
• Bet slip functionality: Building parlays and placing wagers should feel natural
• Live betting capabilities: Platforms with quick in-app scoreboards give you vital advantages

DraftKings shines with its "stylish app" that offers a premium user experience and polished aesthetics. Caesars offers lightning-fast in-app scoreboards and expanded in-play betting options. Both Maine betting sites work on iOS and Android, effectively serving the entire mobile market.

Bonus offers and promotions

Maine bookmakers offer different types of bonuses and their values vary. New customers in Maine can take advantage of several attractive offers, including Caesars' "Bet $50.00 and Receive $100.00 in Bonus Bets" promotion (available until December 13th).

Here's how to evaluate different types of bonuses:

• Match deposit bonuses: Sportsbooks match your first deposit by a set percentage (DraftKings offers 20% up to $100,000)
• Free bets: The sportsbook gives you stakes without using your money
• Risk-free bets: You get your stake back if your bet loses (usually as site credit)
• Cashbacks: You get back some of your losses as a safety net
• Loyalty programs: Regular betting earns you special perks

Each promotion has terms and conditions. Look for validity periods, minimum wagering requirements, market restrictions, and wagering requirements. Failure to meet these conditions may cost you your bonus funds.

The Caesars Rewards program has been called one of the best in the gaming industry. Players can earn points by wagering and redeem them for wagering perks or rewards at Caesars' casino resorts.

How to Sign Up and Start Betting in Maine

To bet on sports in Maine, you must follow specific steps that comply with state regulations. You can start betting within minutes of choosing your platform and completing a simple registration process. Let's take a look at each part of this journey, from registration to cashing out.

Step-by-step registration process

Maine betting sites require you to take a few key steps to get started. The entire process takes less than five minutes according to industry data:

1. Choose a platform - Choose between DraftKings (partnered with the Passamaquoddy Tribe) or Caesars Sportsbook (partnered with three Wabanaki tribes).
2. Download the app - Get it directly from the Apple App Store or Google Play Store. Apple users will find a simplified experience with all major sportsbooks accessible.
3. Create your account - Look for the "Join" or "Register" button on the home page to begin setting up your account.
4. Enter Personal Information - You must provide accurate information such as your full name, email, date of birth, and address. The Platform will verify this information during the identity verification process.

Offshore betting sites use a similar setup process, but lack the oversight of the Maine Gambling Control Unit. As a result, many bettors stick with state-licensed operators for better security.

Verifying your identity and location

Identity checks are a critical security step at all licensed Maine betting sites. This process serves two main purposes: making sure you're 21 or older and preventing fraud.

You'll need these items to verify your account:

• Social Security Number - At least the last four digits for all platforms
• Government-issued ID - Your driver's license or passport might be needed
• Utility bill - Some sites ask for this to check your address

Location tracking is also important because state rules only allow bets from within Maine. Mobile operators use advanced location tracking that:

• Checks where you are before your first bet
• Rechecks fixed connections every 20 minutes (or every 5 minutes near state lines)
• Instantly verifies your spot after any IP changes
• Does up to five quick checks in 5 minutes if it loses your location data

Your betting session will be terminated if the system cannot confirm that you are in Maine after several attempts.

Making your first deposit

The next step after setting up and verifying your account is to add money. Maine betting sites give you several ways to deposit money. DraftKings lets you start with as little as $5 as your minimum deposit.

Popular ways to add money include:

• ACH/e-check (sometimes called VIP Preferred) - Easy to use with high success rates
• PayPal/Venmo - Quick processing without extra costs
• Online banking transfers - Links directly to your checking account
• Play+ prepaid cards - Better acceptance rates and higher daily limits

Maine does not allow credit card deposits for sports betting. Here's how deposits typically work:

1. Head to the banking section (usually shown with a dollar sign)
2. Click "Deposit" and pick your method
3. Type in how much you want to add
4. Put in your banking info or log into your payment service
5. Confirm everything

Your money appears instantly, ready to bet.

Placing your first bet

Your funded account means you're ready to bet on Maine sportsbooks. DraftKings says it's easy - log in, choose your sport and bet, place your money, and see what happens.

The betting screen shows sports by type with big events at the top. After selecting your sport:

1. Look through available bets (moneyline, spread, totals, props)
2. Tap your pick to add it to your bet slip
3. Put in how much you want to bet
4. Check what you might win
5. Lock in your bet

New players often like Money Line bets because they're simple - just pick the winning team. More experienced bettors may try parlays and props for bigger potential payouts.

Withdrawing your winnings

Getting your money out is probably the best part of sports betting. You can usually withdraw your money the same way you deposited it, with e-wallets being the fastest option.

Here's how you get your money:

1. Find the "Withdraw" button in your banking menu
2. Pick how you want to get paid
3. Enter the amount
4. Confirm everything

Different methods take different amounts of time - e-wallets take about 24 hours, while bank transfers take 3-5 business days. You can use ACH/e-check, PayPal, online banking, or receive checks by mail.

Your first withdrawal requires additional security checks to prevent fraud. Most sites will ask to see your government ID before sending your first withdrawal. You only need to do this once, making future withdrawals easier.

Keep in mind that Maine betting sites have minimum withdrawal amounts, usually starting at $10. Major platforms like DraftKings and Caesars don't charge fees for most withdrawal methods.

What You Can and Can’t Bet on in Maine

The Maine betting market offers many betting options. Players need to know what they can legally wager on in order to make the most of Maine betting sites and avoid any problems when placing their bets.

Allowed sports and events

Maine betting sites give you access to a full range of professional sports contests. You can legally wager on all major professional leagues, including:

• NFL, NBA, MLB, and NHL games
• NASCAR, Formula 1, and other motorsports
• PGA Tour golf events
• ATP and WTA tennis tournaments
• UFC and boxing matches
• International soccer leagues (Premier League, La Liga, Bundesliga)

eSports and table tennis have become popular options at Maine betting sites. DraftKings and Caesars Sportsbook let you bet on Olympic events during the Summer and Winter Games.

Restrictions on college teams

Maine takes a strict approach to college betting. State law does not allow betting on any college team based in Maine. This rule applies to all but one of these schools: University of Maine, Bates College, Bowdoin College, and Colby College.

You can still bet on tournaments that include Maine teams. To cite an example, see March Madness - you can bet on the entire tournament, but not on games involving Maine schools.

Betting on out-of-state college teams is allowed. Football and basketball bring in big betting numbers during their seasons.

Prohibited bet types

Maine betting sites have certain types of bets that they cannot offer. These include:

• Political elections and events
• Entertainment awards shows (Oscars, Emmys, Grammys)
• Reality TV show outcomes
• Weather-related propositions
• Virtual or simulated sporting events (unless specifically approved)

Player drafts have their own limits on what you can bet. Maine rules do not allow betting on negative outcomes such as strikeouts or turnovers. The focus remains on positive performances.

Reviews of Maine betting sites show that the Maine market offers about 80-90% of the betting options you'd find in larger states like New Jersey or Pennsylvania.

Final Thoughts on Maine Betting Sites

Maine's betting market has changed dramatically since its launch in November 2023. The state generated $524.4 million in handle in 2024, which is remarkable for its modest population of 1.37 million. Undoubtedly, this rapid growth demonstrates strong consumer interest and points to promising expansion ahead. DraftKings and Caesars lead the regulated market, while offshore options like BetOnline and Bovada remain popular with bettors seeking broader market access.

Your ideal betting platform choice depends on five key factors. An easy-to-use interface makes a big difference in everyday betting, as evidenced by DraftKings' 4.8/5 app rating from over 725,000 reviews. Each operator's bonus structure varies widely, from simple free bets to big deposit matches worth thousands. Superior platforms stand out for their banking efficiency - e-wallet withdrawals take just 24 hours compared to 3-5 days for regular bank transfers.

Green gaming practices should guide your betting activities. Maine law requires strict age verification (21+), location tracking, and self-exclusion options on licensed platforms. Bettors should be aware of key restrictions, particularly the prohibition against betting on in-state college teams, regardless of the venue.

The current market allows for four licensed mobile operators, suggesting that new platforms may soon enter this lucrative space. Maine bettors can look forward to increased competition in 2025, bringing better odds, bigger promotions, and a better user experience. They may prefer the security of state-regulated platforms or the expanded offerings of offshore sites. It makes sense to get a full picture of each option based on the criteria we discussed before placing your first bet.
