Is Gambling Legal In Montana At 18?
Yes, almost everywhere. Montana sets 18 for all the gambling it licenses: video poker and keno machines in bars and taverns, live poker, bingo, the lottery and sports betting through Sports Bet Montana. Some venues and tribal casinos set 21 for themselves.
Legal Gambling Age In Montana
Montana’s legal age is 18 across the board, by state law, for machines, card games, bingo, keno, raffles, sports betting and the Montana Lottery. Tribal casinos set their own age, and some bars and casinos choose 21 because they serve alcohol, so check before you go.
Legal Status Of Gambling In MT
Montana’s gambling happens in person. The Department of Justice’s Gambling Control Division licenses about 1,300 to 1,400 bars and taverns with some 16,500 video gambling machines, up to 20 per location, with a $2 maximum bet and an $800 top prize, along with live card games. Sports Bet Montana, run by the Montana Lottery since 2020, is the state’s only sportsbook, at about 568 licensed venues.
Tribal casinos operate under compacts with the same limits, so there are no house-banked table games such as blackjack or craps. Montana has no online casinos, online poker or statewide mobile sports betting; the Legislature next meets in 2027.
Is Online Gambling Legal In Montana?
No. Montana licenses no online casinos or poker, and its sportsbook app works only inside a licensed venue. A 2025 law made the ban on internet gambling explicit.
Are Offshore Gambling Sites Legal In Montana?
They sit in a legal gray area, and Montana is among the strictest states about them. Its law defines internet gambling as an illegal gambling enterprise, and a 2025 law extended that plainly to offshore and sweepstakes sites and made running one, or advertising or soliciting for one, a crime that can be a felony. Montana’s statutes aren’t aimed at the player. Federal law is likewise aimed at the businesses that take bets, and since the Supreme Court’s ruling in Murphy v. NCAA in 2018, each state has set its own sports betting rules.
The sites we recommend hold licenses from regulators abroad; check that a site still takes Montana players before you join.
