Maine has a small but unusual legal sports betting market. Instead of opening the door to a long list of national sportsbook apps, Maine built its mobile market around federally recognized tribes, with the Maine Gambling Control Unit overseeing sports wagering operators, mobile platforms, facility wagering, suppliers, management services, and related licensing. The GCU’s current sports wagering operator list names DraftKings Inc., Caesars Sports Book, and Oxford Casino-Hotel & Sports Book.

For online bettors, the practical statewide app choice is currently between DraftKings Sportsbook and Caesars Sportsbook. Oxford Casino-Hotel & Sports Book belongs in the legal Maine betting conversation because it appears on the GCU operator list, but it should be treated as a facility/retail sportsbook option unless current statewide mobile app availability is separately confirmed through the operator or regulator.

This guide compares the best Maine betting sites for 2026, including legal sportsbook apps, retail/facility betting, Maine’s tribal mobile-license model, bonuses, payments, college restrictions, New England team betting, online casino status, offshore sportsbook risks, and responsible gambling resources.

Maine separates mobile sports wagering from facility sports wagering. A mobile sports wagering license may be issued to a federally recognized Indian tribe in Maine, while a facility sports wagering license may be issued to eligible casinos, commercial tracks, and off-track betting facilities.

Maine sports betting is regulated by the Maine Gambling Control Unit, which administers and enforces the state’s sports wagering laws and rules. The GCU says sports wagering includes wagers placed in person at a facility operator or through approved mobile applications and digital platforms.

Before using a Maine betting site, know these rules:

• You must be at least 21 years old.
• You do not have to be a Maine resident.
• You must be physically located inside Maine to place a mobile sports wager.
• Legal mobile betting must use an approved Maine operator.
• Mobile operators must use geolocation controls.
• Maine’s current statewide online app market is limited compared with larger states.
• Facility sportsbook betting is separate from statewide mobile app betting.
• High school sports betting is prohibited.
• Events where most participants are under 18 are prohibited.
• Events involving Maine college teams are prohibited, regardless of where the event takes place.
• Tournament games may be allowed only when a Maine college team is not participating in that specific game or match.
• Legal sports betting does not mean all online casino apps are legal in Maine.

Maine does not appear to have a simple standalone statewide ban on all college player props in the way some states do. However, all markets must be approved and offered by a licensed operator, and wagers on events involving Maine college teams are prohibited. In practice, users should check the live Maine app catalog and avoid assuming a college prop available in another state is available in Maine.

Maine also restricts certain wager types. Operators may not accept wagers on injuries, penalties, player disciplinary rulings, or replay-review outcomes for sports events governed by a U.S.-headquartered sport governing body.

Maine bettors do not have the kind of 10- to 20-app menu available in states such as New Jersey, Pennsylvania, Ohio, or Arizona. The online market is essentially a two-app market, while Oxford Casino-Hotel & Sports Book adds a Maine facility sportsbook option.

Oxford is included because it appears on Maine’s current sports wagering operator list, but bettors should treat it as a facility sportsbook option, not a statewide mobile app, unless Oxford or the Maine Gambling Control Unit confirms mobile availability.

Sportsbook / Betting Option	Best Maine Fit	App / Feature Strength	Best User Type
Caesars Sportsbook	Multi-Wabanaki partnership	Mobile and desktop betting, Caesars Rewards	Rewards users and casual bettors
DraftKings Sportsbook	Passamaquoddy partnership and New England sports fit	Props, same-game parlays, futures, live betting	Active bettors and bet builders
Oxford Casino-Hotel & Sports Book	GCU-listed facility sportsbook	Retail/facility wagering; not a statewide app unless separately confirmed	Oxford-area and in-person bettors

Maine’s review section is shorter than most state pages because only two legal online sportsbook apps are currently clear statewide options. Oxford still deserves coverage because the official operator list names it as a sports wagering operator, but it should be positioned differently from DraftKings and Caesars.

Caesars has one of the clearest Maine-specific stories because it launched through a partnership with three Wabanaki Nations: the Houlton Band of Maliseet Indians, the Mi’kmaq Nation, and the Penobscot Nation. Caesars also announced mobile and desktop sports wagering in Maine, which matters for bettors who prefer using a computer instead of only a phone.

The app fits Maine users who want a legal sportsbook tied to rewards, major pro sports, and a familiar casino-style account experience. Patriots, Celtics, Red Sox, Bruins, golf, UFC, NASCAR, soccer, and approved non-Maine college markets can all be part of the betting menu, depending on current sportsbook catalog approvals and market availability.

Caesars’ main betting functions include pregame markets, live betting, props, futures, parlays, same-game parlay-style features where available, in-app scoreboards, and Caesars Rewards tracking. The rewards connection is the reason Caesars should not be treated as a generic backup app in Maine.

Best for: Rewards-focused Maine bettors and users who value desktop/mobile access.
Top strengths: Wabanaki Nations partnership, Caesars Rewards, mobile and desktop access, major-sport coverage, live betting, futures, and rewards redemptions.
Potential drawback: Bettors who want heavier prop menus and more bet-building variety may find DraftKings more flexible.
Conclusion: Caesars is a core Maine sportsbook because it combines legal statewide access, a multi-tribal partnership, desktop betting, and a rewards system that gives it a different identity from DraftKings.

DraftKings operates in Maine through its relationship with the Passamaquoddy Tribe. DraftKings announced the agreement in 2023, describing it as the path to launching its online sportsbook in Maine through the Passamaquoddy partnership.

DraftKings is the better fit for Maine bettors who want a more feature-heavy sportsbook. The app is built around pregame betting, in-game wagering, same-game parlays, player props, futures, alternate lines, and larger event menus. That matters in Maine because many bettors follow Boston and New England teams rather than in-state pro franchises.

The Boston connection also gives DraftKings a natural regional fit. Patriots, Celtics, Bruins, and Red Sox bettors can use it for the kinds of bet-building tools that are harder to replace in a two-app state.

Best for: Maine bettors who want more bet-building control.
Top strengths: Passamaquoddy Tribe partnership, New England sports relevance, player props, live betting, same-game parlays, futures, and alternate lines.
Potential drawback: The app has more layers than Caesars, so bettors who want a lighter experience may need more time with the interface.
Conclusion: DraftKings is the best Maine betting site for users who want a larger wagering toolkit around New England pro teams, national events, and approved non-Maine college markets.

Oxford Casino-Hotel & Sports Book appears on the Maine Gambling Control Unit’s current sports wagering operator list, which makes it part of the legal Maine betting-site discussion. Its role is different from DraftKings and Caesars, though. Oxford should be described as a facility sportsbook unless current mobile availability is confirmed through official sources.

That distinction matters. Maine law separates facility sports wagering from statewide mobile wagering, and Oxford’s public sportsbook page focuses on facility wagering, house rules, betting tickets, and in-person sportsbook procedures.

Oxford’s best audience is the bettor who wants an in-person sportsbook experience, a Maine casino setting, or a retail alternative to mobile wagering. It can matter for bettors near Oxford, casino visitors, and users who prefer placing bets at a physical location.

Best for: Retail bettors and Oxford-area casino visitors.
Top strengths: Maine facility sportsbook status, in-person wagering, casino-property setting, and local retail relevance.
Potential drawback: It should not be positioned as a statewide online sportsbook app without fresh confirmation.
Conclusion: Oxford Casino-Hotel & Sports Book gives Maine a legal facility sportsbook option, while DraftKings and Caesars remain the two main statewide online betting apps.

Maine sportsbook rankings should start with legal status and state fit, not bonus size. With only two main statewide online apps, the goal is not to manufacture a long ranking. It is to explain which legal option fits which bettor.

Ranking Factor	Weight	What We Evaluated
Licensing and safety	25%	GCU operator status, legal app availability, geolocation, account security, responsible gambling tools
Maine-specific relevance	20%	Tribal partnerships, facility sportsbook status, New England sports fit, local legal structure
Betting markets	15%	NFL, NBA, MLB, NHL, soccer, golf, college rules, props, futures, live betting
App and desktop experience	15%	Remote signup, navigation, bet slip, mobile performance, desktop access, account tools
Odds and bet-building value	10%	Props, same-game parlays, futures, live markets, line comparison
Bonuses and promos	10%	Maine availability, opt-in rules, bonus terms, expiration, eligible markets
Payments and support	5%	Deposit methods, withdrawals, cashier reliability, customer support, complaint handling

Because the state has only two main online apps, some categories naturally name both apps.

Category	Best Pick	Why
Best overall Maine betting site	DraftKings	Better fit for users who want more betting tools
Best for beginners	Caesars	Desktop/mobile access and rewards-led layout may feel easier to start with
Best for rewards	Caesars	Caesars Rewards gives it the clearest loyalty angle
Best desktop betting option	Caesars	Caesars launched mobile and desktop wagering in Maine
Best for props	DraftKings	Better fit for player props and alternate markets
Best for same-game parlays	DraftKings	Stronger bet-building fit
Best for futures	DraftKings or Caesars	Check both apps because Maine has limited line-shopping options
Best for live betting	DraftKings	More natural fit for active in-game bettors
Best for soccer/international sports	DraftKings	Better fit for broader event-menu shoppers
Best for retail/facility wagering	Oxford Casino-Hotel & Sports Book	GCU-listed facility sportsbook
Best for line comparison	DraftKings and Caesars	Maine bettors should use both legal apps when price matters

Maine allows online sportsbook users to register remotely with approved mobile operators. Legal mobile wagering still depends on identity verification, age checks, account controls, and geolocation.

1. Choose DraftKings or Caesars.
2. Download the sportsbook app or use an approved desktop site where available.
3. Create an account with your legal name, date of birth, address, email, phone number, and required identity details.
4. Confirm you are at least 21 years old.
5. Enable location services.
6. Add an approved deposit method.
7. Review Maine-specific bonus terms before opting in.
8. Place bets only while physically located inside Maine.

Do not place bets for another person or allow another person to use your account. Maine rules identify suspicious wagering activity to include activity attempted through an agent or proxy, also described as messenger wagering.

Maine sportsbook promos should be checked carefully because offers can vary by state, app, user eligibility, sport, wager type, minimum odds, and expiration date. Do not rank DraftKings or Caesars only by the biggest advertised welcome offer.

Offers last reviewed: May 28, 2026. Check the sportsbook’s Maine-specific terms before depositing or betting.

Sportsbook / Betting Option	Bonus Type to Watch For	Best For
Caesars Sportsbook	Welcome offers, odds boosts, rewards-linked promos	Rewards users and casual bettors
DraftKings Sportsbook	Welcome offers, profit boosts, parlay promos, bonus bets	Prop, parlay, and futures bettors
Oxford Casino-Hotel & Sports Book	Retail/facility promos, if offered	In-person bettors

Before claiming any Maine sportsbook promotion, check:

• Whether the offer is available in Maine.
• Whether you must opt in first.
• Minimum deposit requirements.
• Qualifying wager rules.
• Minimum odds.
• Eligible sports and wager types.
• Whether parlays or live bets qualify.
• Promo expiration date.
• Bonus-bet expiration date.
• Whether bonus bets return the stake.
• Withdrawal, rollover, or playthrough rules.
• Whether college markets are excluded.
• Whether the promo is mobile-only, desktop-only, or facility-only.

Maine bettors should also avoid assuming that a promotion shown in another state applies in Maine. The legal app list is much shorter, and each operator’s Maine house rules and catalog control what can actually be offered.

Payment methods can vary by sportsbook, bank, card issuer, fraud checks, app channel, and account history. Maine rules allow operators to maintain mobile sports wagering accounts, but operators are not allowed to provide credit to patrons for sports wagering.

Do not assume credit cards are accepted. Maine rules prohibit operators from extending credit, and cashier availability can vary by sportsbook, issuer, bank, and current Maine law.

Payment Method	Typical Use	Notes
Online banking / ACH	Deposits and withdrawals	Useful for verified bank transfers; timing varies.
Debit card	Deposits	Acceptance depends on the operator and card issuer.
PayPal / digital wallet	Deposits and withdrawals	Check Maine availability inside the specific app.
Sportsbook prepaid card	Deposits and withdrawals	Availability varies by operator.
Cash at facility sportsbook	Retail account activity or in-person betting	Most relevant to facility operators.
Promotional credit	Bonus-bet use	Read stake-return and expiration rules.
Credit / credit cards	Do not assume availability	Operators cannot extend credit; app rules may be stricter.
Cryptocurrency	Not Available	Maine-Regulated sportsbooks don’t allow crypto. See our offshore betting guides for safe crypto options.

Maine’s approved betting menu can include professional sports, college sports, amateur sports, motor vehicle racing, international events, and esports, but the specific market must be approved and offered by the sportsbook. Maine law defines sports wagering broadly enough to include sports events, portions of sports events, individual performance statistics, and combinations of those markets when approved by the director.

The key limitations are state-specific: high school sports are prohibited, events where most participants are under 18 are prohibited, and games involving Maine college teams are prohibited. Esports is included in Maine’s sports-event definition, but availability still depends on approved markets and operator catalogs.

Market Type	Examples Maine Bettors May Find
Major pro leagues	NFL, NBA, MLB, NHL, WNBA, MLS
New England teams	Patriots, Celtics, Red Sox, Bruins, Revolution
College sports	Approved non-Maine college football and basketball markets
Maine college teams	Prohibited when a Maine college team participates
Combat sports	UFC/MMA and boxing
Individual sports	Golf and tennis
Motorsports	NASCAR, Formula 1, IndyCar
International sports	Soccer, rugby, cricket, international basketball, global tournaments
Esports	Available only when approved and offered
Bet types	Moneylines, spreads, totals, futures, parlays, same-game parlays, live betting, team props, professional player props

Maine does not have its own NFL, NBA, MLB, NHL, or MLS franchise, so betting interest often follows New England teams, Boston sports, national college games, golf, NASCAR, combat sports, and major international events.

Team / Sport	What to Look For	Best-Fit Sportsbooks
New England Patriots	NFL props, futures, live betting	Caesars, DraftKings
Boston Celtics	NBA props, playoff markets, futures	DraftKings, Caesars
Boston Red Sox	MLB moneylines, run lines, pitcher props	DraftKings, Caesars
Boston Bruins	NHL puck lines, futures, live betting	Caesars, DraftKings
Maine Black Bears	Maine college restrictions	No legal bets on games involving Maine teams
Non-Maine college basketball	Approved tournament and national markets	DraftKings, Caesars
New England Revolution / soccer	MLS, Premier League, Champions League	DraftKings, Caesars
Golf	Outrights, matchups, majors	Caesars, DraftKings
NASCAR / motorsports	Race winners, driver matchups, futures	DraftKings, Caesars
UFC / boxing	Fight lines, round props, method props	DraftKings, Caesars

Caesars deserves a look for rewards-focused Patriots bettors across a full NFL season, while DraftKings fits users building weekly props, same-game parlays, and alternate-line wagers.

For Celtics, Red Sox, and Bruins markets, DraftKings usually has the stronger bet-building use case. Caesars remains worth checking for futures, rewards value, and alternate pricing.

There is no best Maine sportsbook for betting on Maine college teams because those events are prohibited. Maine law bars wagers on collegiate sports or athletic events involving a Maine collegiate sports team, regardless of where the event takes place. The exception is limited to tournament games in which a Maine college team is not playing in that specific game or match.

That rule matters for the Maine Black Bears, Maine Maritime, Bowdoin, Bates, Colby, Husson, Southern Maine, and other in-state college programs.

Offshore sportsbooks are not licensed, regulated, or approved by the Maine Gambling Control Unit. The GCU says a person or entity may not engage in Maine activities requiring a sports wagering license unless all necessary licenses have been obtained under Maine law and rules.

If a site is not on Maine’s current GCU operator list or clearly connected to an approved Maine operator, do not treat it as a legal Maine betting site.

Maine has a new internet-gaming framework, but bettors should not treat sportsbook access as online casino access. The Maine Gambling Control Unit now has an Internet Gaming page and says it is responsible for administering and enforcing laws and rules governing internet gaming, including licensing and operation of internet-gaming mobile operators, management services, suppliers, and employees.

Governor Janet Mills announced in January 2026, that LD 1164 would become law, authorizing Maine’s tribal governments to operate online gambling. The announcement also noted that the GCU would develop rules and standards for the new form of gambling.

That does not mean every national online casino app is live or approved for public Maine users. Until GCU-approved internet-gaming operators and public platforms are clearly available, bettors should treat regulated Maine online casino access on hold.

Maine’s market is easy to misunderstand because it has legal online betting but only a small statewide app lineup.

• Assuming FanDuel, BetMGM, bet365, Fanatics, BetRivers, or Bally Bet are legal Maine sportsbook apps.
• Confusing fantasy contest operators with sports wagering operators.
• Trying to bet from New Hampshire, Canada, or another state.
• Betting near the border without allowing geolocation to confirm your Maine location.
• Treating Oxford Casino-Hotel & Sports Book as a statewide online app without official confirmation.
• Betting on games involving Maine college teams.
• Assuming every college player prop available elsewhere is approved in Maine.
• Using offshore sportsbooks because Maine has only two main online apps.
• Claiming a bonus without checking opt-in rules, minimum odds, and expiration.
• Assuming online casino apps are live because Maine enacted internet gaming legislation.
• Using crypto-heavy sites and assuming they are regulated.
• Ignoring deposit, time, wager, or cooling-off tools inside the app.

Maine responsible gambling support is separate from sportsbook customer service. A sportsbook can help with account access, password issues, cashier questions, and app tools. The Maine Gambling Control Unit handles regulatory oversight and complaints. Problem gambling services are for confidential help, treatment referrals, self-exclusion, and recovery support.

Maine DHHS directs people to 211 Maine for confidential problem gambling resources: visit 211maine.org, call 211, or text your ZIP code to 898-211.

ADEPT Maine manages problem gambling services and says self-exclusion for casinos and sports wagering is available online. Users can contact the Problem Gambling Services Coordinator to begin the process.

Helpful Maine resources include:

• 211 Maine: Call 211 or text your ZIP code to 898-211.
• National Problem Gambling Helpline: 1-800-GAMBLER.
• ADEPT Maine Problem Gambling Services: (207) 620-5229.
• Maine Gambling Control Unit: regulator and licensing oversight.
• In-app tools: deposit limits, wager limits, time limits, cooling-off periods, self-exclusion, and account history.
