Yes. Montana is one of the few states that has their minimum age set to 18 years old for all forms of gambling. This includes betting on sports, gambling on casino games, wagering on horse races, or purchasing a lottery ticket.

Online casino gambling or web-based poker is not common in the USA, but that doesn’t mean MT won’t consider adopting these practices at a later date. For now, state-regulated gambling is restricted to in-person venues.
Offshore gambling sites are the only legal option for placing a bet on sports, playing hands of poker, or wagering on casino games over the Internet in MT. International betting sites are only subjected to the laws in their country, and can legally accept members in Montana or across the country.

Casino Age In Montana
The minimum age to gamble on casino games in Montana is 18 years old. This applies to all gaming hubs that offer electronic gambling machines around the state. Some of MT’s tribal casinos have opted for a minimum age of 21 due to the service of alcohol.
Even though the minimum age is 18, casinos reserve the right to restrict anyone 20 and under from entering and gambling.
Are Casinos Legal In Montana?
Yes. The state has authorized ten tribal casinos that operate on Native American lands. These venues are similar to what you’d find in Nevada on the Las Vegas Strip, as they feature gaming floors with slots and table games, poker rooms, and even sports betting in some cases.
Although the minimum age for casino gambling is 18 in MT, many of these tribal locations do not allow anyone under 21 to gamble.

MT has not yet warmed up to the idea of offering online casino gambling despite the numerous land-based opportunities available. The state is more concerned about driving business to these locations, and online options would keep players at home.
This is not a common option in the USA, as only 7 states permit locally regulated eGaming. The good news is, offshore casino sites accept members in MT and allow them to play online slots, blackjack, roulette, and other popular table games, all at the age of 18.
Any gambling site that is based overseas is not subject to federal or state gambling laws. This creates a legal scenario where locals in Montana who are at least eighteen can sign up for an account and start gambling without violating any current regulations.

18 And Up Online Sports Betting Montana
While there are numerous kiosks around the state that will accept your sports bet at the age of eighteen, politicians have yet to pass a bill that will allow online sportsbooks to exist locally. The entire spectrum of sports betting in MT is run by the state lottery, and so far, online options have not generated much interest.
The reason for being optimistic about the potential for domestic sportsbook sites in the future is the enormous amount of revenue they generate. The situation is layered with tribal interests, but they could adopt a Florida model where the Native American gaming groups are offered a piece of the pie.
If you want to bet on sports online today, anyone aged 18 and older that is standing in MT can sign up for an account with an offshore sportsbook site. We’ve compiled a list of the best sports betting sites that serve the area and have included convenient links that will take you directly to their homepage.
These websites offer betting odds for all major professional and college sports and have no restrictions for wagering on local NCAA programs. Until the state legislature changes their tune on local online options, these sites will remain the best and only legal option around.
