Top Legal Games to Play at Montana Casinos
Montana offers a variety of gambling options despite its tricky history with many forms of gambling. Land-based casinos provide the traditional range of casino games from blackjack to roulette, although these are only permitted as tribal casinos. Free online slots are the most convenient way to play online casino games in Montana, given the state's strict regulations on online gambling.
Montana has 13 live horse racing dates on the calendar, and online advance-deposit wagering on horse racing is also legal in the state. Charitable raffles, bingo, keno, panguingue, poker, and shake-a-day are also permitted, as are sports pools, fantasy sports leagues, and sports tab games.

How to Win Real Money on Casino Games in Montana
As real-money online casinos are not legal in Montana, the only way to win real money on casino-style games is by playing at Reveal Gaming platforms like Horseplay. Horseplay offers hundreds of casino-style games and is fully legal and licensed by the Montana Board of Horse Racing.
The Return to Player (RTP) percentage is a statistical indication of how much of the total amounts wagered a game will pay out in the long run. For example, a game with an RTP of 94% will pay players $0.94 in winnings for every $1 bet on the game.
However, it is essential to understand that this is a payout number across millions of game sessions, where every game outcome is completely random. So, while one player may suffer a losing streak, another may win a large prize.

Montana Gambling Law
Throughout much of the first half of the 20th century, the state of Montana carried on a love-hate relationship with gambling. As far back as 1899, the Montana state constitution had declared all forms of gambling to be illegal in the state.
Despite this decree, gambling, even illegal slot machines, continued to operate at sites around Montana. In the 1940s, charity gambling was permitted, and pull tabs became popular. It wasn’t until 1950 that Montana lawmakers truly set out to put the clamps on illegal gambling. The Montana Supreme Court, by a 4-1 margin, ruled against the legalization of gambling.
In 1973, the state legislature passed the Card Game, Bingo, Raffles, and Sports Pool Act, bringing back forms of charitable gambling. Keno was added to this collection in 1976. Video poker was legalized in 1984, and the state lottery was created in 1986.
By 1994, Montana approved the first land-based tribal casinos. A significant change occurred in 2019, when the state government approved legal, regulated retail and online sports betting. At the same time, the state legislature was rejecting a proposal to legalize blackjack.

History of Online Gambling Laws In Montana
Like many states in the Wild West, the Montana government once sought to shut down all forms of gambling. Illegal gambling was prevalent across the state for much of the first part of the 20th century. That was finally reigned in during the 1950s, and it wasn’t until the 1970s that state government officials slowly began to remove the shackles on different forms of gambling in Montana.

Legal vs Offshore Casinos in Montana: What’s the Difference?
You’ve probably seen ads for online casinos claiming they are available to play in Montana. While this is technically true, those sites don’t tell you that playing real money online casino games is against US law. While there’s no record of anyone ever being charged for gambling at one of these so-called offshore casinos, the fact of the matter is that you play at these sites at your own risk.
Since the state does not regulate these sites, you have no recourse if you score a big win and don’t get paid. There’s no assurance that these sites are taking any precautions to protect your personal information or the money in your account. Likewise, if the site shuts down suddenly, you’d have no method through any regulatory body to be sure you’d get your money back.
