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.

Is Online Gambling Legal In Montana?
At this time, there is no locally regulated online gambling for players of any age in the Treasure State. Since the region offers local sports betting, we wouldn’t be surprised to see them offer domestic sportsbook sites or mobile apps in the near future.
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.
18+ Casinos In Montana

Online Casinos In Montana For 18 And Up
There are only a few states that offer online casinos, and unfortunately, the Big Sky Country isn’t one of them. Considering the number of gaming options in MT, there is a chance that lawmakers could make a push to legalize them at some point.
The only legal option for 18+ online casino gambling at the moment is by becoming a member of a betting site that is located overseas. These sites don't have to adhere to local laws because they are only bound by the regulations in their home countries.
The casinos listed here on this page are our top recommendations for online gambling in MT. Each of them has earned our trust through long term membership and legit payouts, and they all accept players starting at eighteen years old.
Most Trusted 18 And Up Casinos In Montana
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.
There are also numerous gaming hubs around the state that feature electronic gambling machines offering keno, poker, and bingo. These venues are 18-friendly, but you may encounter one that requires players to be at least 21 to participate.
Are Online Casinos Legal In Montana
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+ Sports Betting In Montana
Anyone who is at least 18 and standing in the Treasure State can legally bet on sports at a retail sportsbook location. Sports Bet Montana, which is run by the state lottery, is the only operating sportsbook in the region.
Bets must be placed at electronic kiosks that can be found in gambling venues and casinos throughout MT. There is no online or mobile option available. There is an online and mobile sportsbook that allows you to submit a wager and create a barcode that you can then pay for at an in-person location.
If you are interested in betting on sports online at 18, there are several international gambling sites that serve the area and accept under 21 players. However, not all of them are reputable, which is why we’ve created this guide.
By choosing any of the sportsbook sites that we link to on this page, you are guaranteed to find a legitimate operator who will pay out your winnings when the time comes. Venturing outside of these top online sports betting sites is not advisable.
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.
Best Montana Sports Betting Sites For March 2025
Is Sports Betting Legal In Montana?
Yes. Current law allows for local sports betting with a minimum age of 18. The local sports betting industry is entirely controlled by the Sports Bet Montana, a sportsbook that is regulated by the state lottery.
All wagers must be placed using electronic kiosks that can be found in casinos or gambling venues located around the state. There are no domestic online or mobile options at the moment, but offshore sportsbook sites will allow you to bet over the web or using your smartphone.
Is Online Sports Betting Legal In Montana?
The Treasure State has been hesitant to legalize local sports betting sites despite the presence of numerous retail locations that will accept your wager. Much of the issues are due to Native American casinos and their desire to control a majority of the industry.
Signing up for an account with an offshore sportsbook in Montana is legal because there are no laws that prohibit them from operating within the state’s borders. Because these betting sites are located in another country, they are only required to obey the laws that are enacted there.
What Sports Betting Apps Are Legal In MT?
There are over 100 locations in the Treasure State that will allow anyone 18 or older to place a wager on sports. The same is not true for mobile betting apps, as area politicians have not voted to allow any web-based gambling options despite strong demand.
You can use your tablet or smartphone to access Sports Bet Montana and arrange a wager, but you'll then have to travel to a local kiosk to finalize the wager. Despite the lack of local avenues for mobile sports gambling, there are many opportunities to bet on your iPhone or Android at any time of day.
Any of the offshore sports betting sites that we recommend should be your first stop for mobile wagering on pro and college games. No download is required to access these apps. All you need is a mobile device that can connect to the Internet.
You can visit the site, log in, and place a wager anywhere in MT right now. All of the options that you can find at the desktop website are also offered on Androids, iPads, and iPhones. These are our preferred venues for placing mobile wagers, so look through our reviews for each of them and consider joining more than one.
18+ Montana Poker Rooms
There are numerous poker rooms around the state of Montana that allow 18 and older players to belly up to the felt and ante up. Some are attached to casinos, while others are featured at bars. We have provided a list of these venues in the dropdown menu below.
Online and mobile poker rooms are not permitted in MT at this time. Web-based games of poker are not offered domestically in many states, and the Treasure State doesn't feature any online gambling at all as of March 2025.
However, there are online poker sites that are based offshore that accept players 18 and up in the Treasure State. These sites can be legally accessed on any web-ready device across MT and offer video poker games as well as competitive head-to-head tables.
18+ Online Poker – Montana
For now, there are no state-regulated websites that offer real-money poker games in Big Sky Country. There is a chance they could become legalized in the future, but considering the state's current lack of any online gambling at all, it could be several years before that happens.
Online poker can be played at the age of 18 if you join an international gambling site like the ones we recommend in this guide. There are numerous offshore poker rooms that will accept Montanans at 18, but we advise restricting your options to the preferred sites that we list here.
The reason that these sites are legal to play poker with is due to their country of origin. They are each based in regions where eGaming is legal, and their regulations permit them to offer online hands of poker internationally, with the USA included.
Best 18 & Up Online Montana Poker Rooms For March 2025
Is Poker Legal In Montana?
Yes. Montana is a legal poker state where anyone eighteen or older can play for real money. Poker tables in MT are limited to in-person venues, and there are currently over 20 locations where players can ante up and gamble.
The only outlet for online poker in MT is to access a gambling site that operates from within another country where it is legal to do so. Each of the poker sites that we feature on this page are located offshore inside a country that has legalized international eGaming.
Is Online Poker Legal In MT?
Yes, online poker is legal in MT, but it is not offered by domestic vendors. Luckily, there are numerous poker sites based overseas that offer legal games over the web in MT. The reason this can happen is because there are no state or federal gambling laws that mention offshore poker rooms.
This provides a clear path for international poker sites to accept players in the US over the web and grant them access to their tables. Anyone in MT who is at least 18 can play poker with these sites, and we've provided a list of the best-ranked options here for your convenience.
Other Options For 18+ Gambling In Montana
Since Montana allows gambling starting at the age of 18, the law allows for a cornucopia of opportunities to place bets at retail locations or by using an offshore operator. Here are some of the options in play for eighteen and older gamblers in MT.
- 18+ Horse Race Betting Online – Local players can bet on the horses at any local kiosk, racebook, or betting site that resides overseas at the age of 18. There are also options for off-track betting via video feeds at in-person locations.
- 18+ Political Betting Online – Betting on election outcomes is a no-no in the USA. However, international sportsbook brands are not subject to state or federal law and offer them for most political events that are covered in the news. Bet on the next President of the United States by visiting any of the sportsbooks we feature here.
- 18+ Entertainment Betting – This is a category that includes betting on celebrities, television shows, movies, and even pro wrestling. Domestic sportsbooks do not offer this type of wagering in any US state, but locals can access these types of odds at any sports betting site that we recommend.
- 18+ Bingo – In-person bingo is legal in the state for anyone who is 18 or over. Some offshore betting sites provide locals games of bingo at 18, but they are single-player video versions that do not resemble what you'll find at a retail venue.
Montana Betting Apps
State-regulated mobile gambling in Montana is not permitted as of March 2025. All forms of gambling in the state are in-person only, but there is always the potential for the position of lawmakers to change down the line.

Legal Gambling Age In Montana
All current domestic forms of gambling in Montana can be done legally at the age of 18. This includes the state's in-person casinos, sports betting, bingo, poker, and lottery. Even though the minimum is 18, some venues restrict entry to players who are 21 and older, so call ahead before you head to one.
The international gambling sites that we suggest here are all 18-friendly, but there are some that only allow 21 and older members. This is largely due to the presence of alcohol sales, so some businesses would rather not risk serving an underage patron.
The sites featured on this page allow you to gamble on sports, casino games, and poker on any web-ready device that can handle current web standards. We have used these apps to gamble remotely for years and rate them above all other mobile betting sites that accept locals.
Legal Status Of Gambling In MT
The only option that locals are waiting for lawmakers to approve is online gambling on sports, poker, and casino games. There are limited online options, but they are restricted and can only be accessed while on the grounds of casinos that offer these types of services.
In-person casino gambling, sports betting, poker tables, bingo, and horse racing betting are legal for anyone who has reached the age of 18 in MT. We expect politicians to adopt online sports betting in the near future because of the added revenue, but web-based casino games may never happen due to tribal gaming interests.
Are Offshore Gambling Sites Legal In Montana?
Yes. Gambling sites that are located in other countries can legally accept members from inside MT as long as they are at least 18. The reason this is possible is because local laws do not govern businesses that are not inside the state. The federal court system recently ruled that online wagers are placed where the servers are located. This means the gambling is not occurring in MT or the USA from a legal standpoint.
Where Can I Gamble In MT Locally?
There are dozens of locations throughout MT that feature kiosks where 18+ players can wager on pro and college sports. Online sports betting is also an option, but only via offshore sportsbooks that are not located in the state. You can visit and sign up with any of our top sports betting sites by clicking any of the links we've provided on this page.
There are a few tribal casinos that offer all popular types of gambling around the state and several bars and restaurants that feature electronic gaming machines that are open to 18-year-old players. If you are interested in online casino gambling in MT, real money games are legally available through any of the offshore betting sites we recommend.
There are a lot of poker rooms scattered across MT that allow 18+ players to partake. Some casino locations run by Native American tribes restrict entrance to anyone under 21 because of alcohol sales. Online poker is limited to international gambling sites, and we've listed our favorite web-based options here in this guide.
If you are at least 18, local and off-track horse race betting is legal at any participating Montana racino or betting kiosk. Currently, there are two operating tracks in the state. Online horse race betting is offered offshore, and you can wager on the results using any sportsbook we mention here.
