Idaho 18+ Casinos
Every casino in Idaho lets players in at 18, and not one of them deals blackjack. In 1992 lawmakers blocked tribal casinos from offering class III games, so blackjack, craps, roulette, keno, baccarat, poker and traditional slot machines are banned statewide. The seven local Idaho casino locations run bingo halls and video-style class II terminals instead.
Eighteen is the legal age for everything else too: the state lottery, raffles, charitable gambling and pari-mutuel wagering on horse and dog races at the state’s nine racinos. That places Idaho among the states in the US that currently permit 18+ casinos, even if its casino floors look nothing like Las Vegas.
No Idaho law expressly prohibits playing at licensed offshore online casinos, which carry the table games the state bans. The only recorded penalty tied to online gambling was a misdemeanor for playing on state-based sites, which are illegal.

Can You Gamble Legally In Idaho At 18?
Yes, ID residents and visitors can legally gamble at the age of eighteen. This means eighteen-year-olds can participate in Idaho’s state lottery, pari-mutuel wagering on horse and dog races, bingo, raffles, slot-styled video terminals, online offshore gambling, and charitable gambling.
Bingo is actually a very popular form of gambling entertainment in the Gem State. This became so in 1993 when the Coeur d’Alene Casino and Hotel in Worley opened and offered a simple bingo hall. The bingo hall became so popular after its opening that other tribal casinos began offering bingo throughout the state as well.
The Coeur d’Alene Casino was also one of the only casinos to offer a poker room regardless of the state’s prohibition against poker. The casino has currently received an injunction from the state of Idaho to close the poker room, pending court hearings.
Is It Legal To Gamble Online In Idaho?
Yes, while the Gem State offers legal land-based gambling entertainment, there is no state law that expressly prohibits players from enjoying online gambling at online casinos that are legally operating offshore, such as the ones listed on Casinos18. The only recorded punishment relating to online gambling was a misdemeanor for playing forbidden games on state-based online sites, which are illegal in Idaho. You can learn more from our page created to specifically address 18+ casino laws.

Brief Explanation Of Idaho’s Gambling History and Laws
Idaho’s gambling history shows a lot of back and forth between its residents and lawmakers. Once a state as wild as the west could get, with card sharps and gambling players amuck, lawmakers decided to place strict bans on various games of chance and class III games throughout the state’s history.
In the 1930s, slots were popularized in Idaho’s Garden City, Idaho Falls, and Pocatello.
In 1947 slots were legalized statewide.
However, by 1953, lawmakers declared slots unconstitutional and banned them across the state.
In 1963, pari-mutuel wagering on horse races were legalized giving residents a new form of gambling entertainment.
In 1988, the state created its Idaho state-run lottery.
Simultaneously that year, the IGRA or Indian Gaming Regulatory Act passed in Congress, allowing reform to the nation’s gambling laws so federally recognized tribal organizations could forge gaming compacts with the states their lands were located in.
In 1992, ID state lawmakers wanted to curb the potential thriving casino gambling market in their state, which would undo their previous legislative acts, and went on their way to block tribal casino’s access to class III games. Therefore, games like blackjack, craps, roulette, keno, baccarat, traditional slot machines, and poker are banned in the Gem State.
