Legal and everywhere. Bars, taverns and truck stops with a liquor license can run up to 20 video gambling machines — video poker, keno, bingo and line games. State law caps them at a two-dollar maximum bet and an 800-dollar maximum payout per game. There are roughly 16,000 machines across the state — this is what ‘casino’ really means in Montana.
Legal since 2019, but with a catch. Betting is run by the Montana Lottery as ‘Sports Bet Montana,’ and you can only place a wager while physically inside a licensed location — a bar or restaurant with a kiosk. There is no statewide mobile app; the app only works on-site. The minimum age is 18.
Legal, but small-stakes. Licensed card rooms — again, usually attached to a bar — can spread poker and other card games under state rules, with prizes capped at 800 dollars. There are no Las Vegas-style poker rooms; this is low-limit tavern and card-club play, plus some games at tribal casinos and charity events.
Legal, and the closest thing to a real casino floor in Montana. Several of the state’s tribes run Class III casinos under federal compacts — and unlike the bars, they aren’t held to the two-dollar bet and 800-dollar payout caps, so this is where the higher-limit machines and table games are.
Legal since 1987. The Montana Lottery sells Powerball, Mega Millions and in-state draws like Big Sky Bonus and Montana Cash, plus the annual Montana Millionaire raffle. There are no official online ticket sales, but licensed courier apps such as Jackpocket buy tickets on your behalf. The minimum age is 18.
Legal. Live meets run on the fair circuit, simulcast wagering is available statewide, and advance-deposit horse-betting (ADW) apps are permitted for Montana residents. Racing is overseen by the Board of Horse Racing, separate from the state’s other gambling regulator.
Legal for qualifying groups and social settings — bingo, raffles, Calcutta pools, sports-tab games, casino nights and in-person fantasy leagues all fall under Montana’s broad social-gambling rules.
Illegal — and newly so. A 2025 law (SB 555) explicitly outlawed unlicensed internet gambling platforms, making it a felony to run one, with fines up to 50,000 dollars and prison time. There is no licensed online casino or poker in Montana, and offshore sites are unregulated.
Unavailable. Montana law makes it unlawful to wager on a fantasy sports league by phone or over the internet, so DraftKings, FanDuel, PrizePicks and Underdog do not operate here. Only informal, in-person leagues are allowed.
Banned — Montana was the first state to do it. SB 555 (2025) outlawed dual-currency online sweepstakes casinos along with other unlicensed online gambling, effective October 2025. Major sweepstakes sites began blocking Montana players before it took effect.
SB 555 outlawed online sweepstakes casinos, unlicensed internet gambling and prediction markets — a first-in-the-nation move — with felony penalties. Governor Gianforte signed it, and it took effect October 1. Montana’s recent direction has been toward restriction, not expansion.
HB 725 gave the Montana Lottery a monopoly on sports betting, running it on-premises at licensed locations. Governor Bullock signed it and vetoed a competing bill that would have allowed private operators. Betting launched in 2020.
When Congress banned sports betting nationwide, Montana was one of only four states — with Nevada, Oregon and Delaware — exempted, because it already ran sports pools and fantasy leagues. That exemption is why Montana could act so quickly once the ban fell in 2018.
Voters approved a state lottery, adding draw games to a gambling landscape already built on tavern card games and, soon after, video gambling machines.
Montana’s 1972 constitution let the legislature and the people authorize gambling — the legal foundation for the licensed tavern gambling, video machines and lottery that followed.
Montana is a study in contrasts. Few states have more everyday gambling — video gambling machines sit in nearly every bar, there’s poker down the street, sports betting at the tavern, tribal casinos and a lottery. And yet, when it comes to your phone, Montana is one of the most restrictive states in the country.
There is no legal online casino or online poker, and Montana has been actively closing doors, not opening them. In 2025 the state passed SB 555, which made running an unlicensed internet gambling site a felony and made Montana the first state to ban sweepstakes casinos. Even daily fantasy is off-limits: state law specifically bars wagering on fantasy sports over the internet, which is why DraftKings and FanDuel don’t operate here. Full-iGaming states like Pennsylvania, Michigan and New Jersey license real online casinos; Montana is heading the opposite way.
Sports betting is the one online-ish exception, and even it comes with a leash: it runs through the Montana Lottery and only works while you’re physically inside a licensed bar — there’s no statewide app. Montana got that ability early because it was one of just four states — with Nevada, Oregon and Delaware — grandfathered under the old federal sports-betting ban.
So for online casino games and poker, there’s no regulated option, and offshore sites are both unlawful to operate here and unprotected for the player. For a real card game, Montanans play the low-stakes tables in card rooms and tribal casinos, where poker is legal but pots are capped. Neighboring Idaho is even stricter online; for full casinos and mobile sportsbooks, the nearest options are out of state.
The practical reality: Montana’s legal gambling is almost entirely in person — video machines in the bars, on-premises sports betting, low-stakes poker, tribal casinos and the lottery. Online casino, online poker, daily fantasy and sweepstakes are all illegal, and a 2025 law made unlicensed online gambling a felony. There’s no legal online-casino route here, and the state is cracking down on offshore play.
In Montana, ‘casino’ usually means a bar with video gambling machines. Real casino floors are on tribal land. Here’s the lay of the land.

Montana has no Las Vegas-style commercial casinos at all. What it has instead is two very different kinds of ‘casino.’
The first is the one you see on every corner: a bar, tavern or truck stop with video gambling machines. Any business with a liquor license can run up to 20 of them — video poker, keno, bingo and line games — and these are what the roadside ‘CASINO’ signs point to. But they’re tightly capped: a two-dollar maximum bet and an 800-dollar maximum payout per game. There are roughly 16,000 machines in about 1,400 locations, making Montana one of the most gambling-saturated states in the country — about one machine for every 63 residents — even without a single resort casino.
The second kind is the real thing: tribal casinos. Several of Montana’s tribes run gaming under federal compacts — the Assiniboine and Sioux at Fort Peck (Silverwolf), the Chippewa Cree at Rocky Boy’s (Northern Winz), the Crow (Apsáalooke Nights), Fort Belknap, the Northern Cheyenne (Charging Horse) and the Blackfeet (Glacier Peaks), among others. Because these operate under Class III compacts, they aren’t bound by the two-dollar and 800-dollar caps, so the higher-limit machines, table games and larger poker sit here. For a casino floor that feels like a casino, tribal land is the place — and for a mobile sportsbook or an online casino, the nearest legal option is across a state line.
The Gambling Control Division licenses the state's video gambling machines, card rooms and the lottery's on-premises sportsbook, with responsible-gaming rules and a self-exclusion program for state-licensed venues.
Tribal casinos operate under federal compacts and tribal gaming commissions, and the state lottery and pari-mutuel horse racing are regulated, with consumer protections behind them.
No Montana protection. Online casinos, poker and sweepstakes sites are unlicensed and now illegal here — a 2025 law made running unlicensed online gambling a felony. No fund segregation, no recourse.
Our guidance: Montana has plenty of legal, regulated options in person — video machines, on-premises sports betting, low-stakes poker, tribal casinos and the lottery. What it doesn’t have is legal online casino or poker, and the state has just made unlicensed online gambling a felony and banned sweepstakes outright. So there’s no legal online-casino route here; offshore sites are unregulated and now squarely targeted by state law. If gambling stops being fun, Montana’s own helpline is below.
With gambling in nearly every bar, help matters. If gambling stops being fun — or you're chasing losses — free, confidential support is available 24/7 through Montana's own council and national resources.
