Maine is the newest online casino market in the country, and the honest position is that it is legal but not yet open. LD 1164 took effect on 29 July 2026, reserving online casino gaming for the four Wabanaki Nations, but as of July 2026 no app is live: the Gambling Control Unit is still writing the rules and operators are expected in late 2026 or 2027. Until then Maine has no regulated online casino, so any online play is offshore. All 13 offshore casinos we track accept Maine, and we rank them below with the trade-offs stated.

Facts checked against Maine law and casino terms: 23 July 2026
Maine’s online casino market is legal on paper but not yet open. LD 1164 reserved online casino gaming for the state’s four federally recognized Wabanaki Nations, each of which may partner with one operator. As of July 2026 the Gambling Control Unit is still writing the rules, so no app has launched. What we can show is the licensed framework, drawn from the state and the tribes’ own announcements, and we earn nothing from listing it.
| Licensed casino apps | Land-based partner |
|---|---|
| Caesars (announced, not yet live) | Penobscot Nation, Houlton Band of Maliseet Indians and Mi'kmaq Nation |
| Operator not yet announced | Passamaquoddy Tribe |

What the license will buy you: once live, a Gambling Control Unit-regulated app comes with independently tested games, deposits handled under state oversight, real dispute channels and Maine’s responsible-gambling tools. None of that exists offshore. It is worth waiting for if you can, and it is the standard everything below should be measured against once it arrives.
Maine is the newest market in the country, and the honest position today is that there is no licensed alternative yet. Until the tribal apps launch, expected in late 2026 or 2027, an online casino played from Maine is an offshore one. That is the whole pull: they are open, they take Maine, and the regulated version is still months away.
The cost does not change, though. Offshore casinos sit outside Maine law entirely, so if a payout stalls your leverage is the operator’s reputation and our complaints desk, not a regulator, and none of the protections the coming licensed market will carry apply now. On access, all 13 of the offshore casinos we track accept Maine, which is unusual and mostly a sign of how new the state is: no one has restricted it yet. Maine has drawn one clear line already, banning sweepstakes casinos outright in 2026. The ranking below is for readers who want the offshore route before the licensed apps arrive, with the trade-offs stated and the date we last read each casino’s terms on the card.

Most of it, with the newest piece still being built. Online casinos are legal but not yet live, and sweepstakes casinos were banned the same year they were authorized.
| Vertical | Status | The facts |
|---|---|---|
| Online casinos | Legal, limited | Legalized under LD 1164, which Governor Mills allowed to become law and which took effect on 29 July 2026, making Maine the eighth state to legalize online casinos. It is tribal-exclusive: only the four Wabanaki Nations may offer it. As of July 2026 no app is live; the Gambling Control Unit is still writing the rules and operators are expected in late 2026 or 2027. Caesars has signed with three tribes, and the Passamaquoddy hold the fourth license. 21+ once live. |
| Land-based casinos | Legal | Two commercial casinos, both from statewide votes: Hollywood Casino Bangor (2005) and Oxford Casino (2010). Neither is tribal, which is the root of the fight over online exclusivity. |
| Sports betting | Legal | Legal and live since 3 November 2023, also tribal-exclusive: Caesars runs the mobile book for three Wabanaki Nations and DraftKings for the Passamaquoddy. Retail books sit at the two commercial casinos. |
| Lottery | Legal | Maine State Lottery since 1974. |
| Daily fantasy sports | Legal | Legal and regulated: Maine licenses daily fantasy operators through the Gambling Control Unit. |
| Sweepstakes casinos | Illegal | Banned under LD 2007, signed by Governor Mills on 6 April 2026 and effective in mid-July 2026: it prohibits dual-currency sweepstakes casinos with civil penalties of $10,000 to $100,000 per violation. Entertainment-only social games with no cash redemption stay legal. |
| Charitable bingo & raffles | Legal | Licensed beano, games of chance and raffles under the Gambling Control Unit. |
No Maine statute targets an individual player for using an offshore site, and no player prosecutions are documented. Once the tribal apps launch, the legal online age will be 21. Enforcement targets unlicensed operators: online casino rights belong to the four Wabanaki Nations, running a sweepstakes casino is now banned by LD 2007, and offering internet gaming outside the tribal framework is unlawful. The federal UIGEA targets gambling businesses rather than the bettor. Until the licensed tribal apps go live, Maine has no regulated online casino at all, so any online casino play today is offshore and carries none of the protections the coming licensed market will.

Maine legalized online gambling through its tribes, and the fight over who else gets in is still running.
Online sports betting launches on 3 November, reserved for the four Wabanaki Nations, with Caesars and DraftKings as their partners.
Lawmakers pass LD 1164, extending that tribal-exclusive model to online casinos.
Governor Mills signs LD 2007, banning sweepstakes casinos, while the state’s two commercial casinos go to court over being shut out of online gaming.
LD 1164 takes effect on 29 July, making Maine the eighth state to legalize online casinos. Caesars has signed with three tribes; the launch is still expected in late 2026 or 2027.
Once the licensed apps launch they will report qualifying wins to the IRS on a W-2G. Winnings from any source, a coming licensed app, an offshore site or a Maine casino floor, are taxable federally (IRS Topic 419) and under the Maine income tax, which runs up to 7.15% at the top (Maine Revenue Services).
From the 2026 tax year, federal rules let you deduct only 90% of gambling losses against winnings under the One Big Beautiful Bill Act, so a break-even year can still leave you owing. Offshore winnings come with no paperwork at all, which makes your own session records the only trail. The tax is owed either way.
Not yet, as of July 2026. LD 1164 took effect on 29 July 2026, but the Gambling Control Unit still has to write the rules before any operator can go live. Industry timelines point to late 2026 or, more likely, 2027 for the first real launch. Legal on paper is not the same as open.
Only the four Wabanaki Nations: the Penobscot Nation, the Passamaquoddy Tribe, the Houlton Band of Maliseet Indians and the Mi’kmaq Nation. Each may partner with one operator, mirroring the state’s tribal-exclusive sports betting. Caesars has signed with three tribes; the Passamaquoddy, who use DraftKings for sports, hold the fourth license.
There is no licensed option live yet, so any online casino you can reach today is offshore and unregulated. No Maine law targets the individual player, and no player prosecutions are documented, but an offshore site gives you none of the protections the coming licensed apps will. If you can wait for the tribal launch, that is the safer route.
Because the law left them out. LD 1164 gave online casino rights only to the tribes, so Hollywood Casino Bangor and Oxford Casino cannot apply. Oxford’s owner, Churchill Downs, has sued, arguing the tribal-exclusive setup is unconstitutional. That case is one of the reasons the market is not open yet.
No. LD 2007, signed in April 2026 and effective in mid-July, bans dual-currency sweepstakes casinos with civil penalties of $10,000 to $100,000 per violation. Entertainment-only social games with no cash redemption stay legal, but the sweeps model that mimics real-money casino play is prohibited.
Rules change at every border. If you travel, the picture one state over:
