Eighteen is the only number a Montana gambler needs to remember. It is the minimum age for every legal form of gambling in the state, which puts all of Montana’s local gambling options within reach: tribal casinos, the Montana Lottery, horse racing at Yellowstone Downs and off-track at participating bars, and the video poker and keno machines found in bars and convenience stores.

Those casinos run on screens rather than dealers. Tribal casinos may offer only Class II games such as video blackjack, video bingo and video roulette, and since 1991 any establishment with a liquor license can host up to 20 video gaming machines.

Sports betting is open at 18 too. Montana was one of four states grandfathered out of the federal ban on sports betting, and since lawmakers approved local wagering in 2019, kiosks have taken bets in most casinos as well as in bars and restaurants. Our page on gambling laws shows how far that sets Montana apart.

Montana Gambling At 18, Including The Unusual Stuff:

  • Panguingue, cribbage and fishing derbies are all legal forms of gambling.
  • 18+ casinos include Silver Wolf Casino, KwaTaqNuk Casino Resort and Northern Winz Hotel & Casino.
  • Under 18, Montanans can still enter church or school raffles.
  • Voters approved the Montana Lottery in 1986.

Yes, Montana residents can enjoy all of the state’s gambling entertainment options at the ripe age of eighteen. The state offers many land-based casino options that are available to players that are of age and older, as well as many electronic gaming options available at local bars and convenience stores, horse race wagering at Yellowstone Downs, or participating bars and casinos that permit off-track wagering, and social gambling in private residences.

All residents over eighteen may participate in various gambling options. Even children under eighteen can participate in charitable gambling, such as church or school raffles. However, minors are not permitted to enter casinos or participate in other gambling activities outside of charitable games.

Tribal casinos can only offer Class II games, which are defined as video gaming terminals such as video blackjack, video bingo, and video roulette. Spin reels, on the other hand, must be for “entertainment purposes only.” Different video gaming options from the many bars and taverns may offer up to 20 video gaming devices in their establishments, all of which can be video terminals like video poker, video keno, and video bingo.

Montana also allows sports betting and features numerous sportsbook kiosks where wagers can be placed at 18. Online sports betting is also available on the grounds of these venues where available.

It is legal for Montana residents to gamble on legally sanctioned offshore gambling sites, and the state remains unconcerned that locals engage in online gambling. As long as residents use legal sources for their gambling entertainment and not illegal Montana-based online sites or illegal offshore gambling options run by fake authorities and entities, players may enjoy the numerous games and options legal online casinos offer.

Brief History Of Montana’s Gambling Laws

The Treasure State’s gambling history begins like many other Western States, first early settlers brought card games and gambling games along with them, which sparked a thriving lottery market in the 1800s.

In 1889, The new constitution of Montana banned all types of gambling.

After the great depression, Montana repealed its prohibition in 1933, and pull tabs became popularized.

In 1937, the Montana legislature passed The Hickey Act, which legalized a variety of table games only if the county licensed them.

By 1945, slot machines were popping up everywhere and the state of Montana was on the losing end of the battle, thus they decided to legalize them for nonprofit organization purposes and collect taxes from them.

In 1949, Montana allocated $40,000.00 to begin enforcing gambling laws within their state.

By 1950, Montana’s Supreme Court made slots & punch boards illegal.

In 1973, legislatures passed the Card Game, Bingo, Raffles, and Sports Pool Act.

In 1976, to take the place of live bingo, the Supreme Court in Montana legalized video keno.

In 1984, the Montana Supreme Court ruled machines with video poker to be illegal. This was later overturned in 1985 by the passing of the Video Poker Machine Act, which allowed five poker machines per licensed liquor and unlimited keno machines.

In 1986, voters approved of the Montana Lottery.

In 1991, legislators lift the number limit on video poker machines and authorized a new limit, each establishment with a valid liquor license ould host a total of twenty machines for video gambling. That same year, Montana became one of only four states to be grandfathered out of the federal ban on sports betting and currently permits pari-mutuel wagering on horse races and simulcast racing, as well as permitting season-long fantasy sports.

In 2005, the legislation prohibiting Internet gambling was approved.

In 2019, state lawmakers approved local sports betting. Kiosks now accept bets in most casinos as well as bars and restaurants.
