gambling at 18 and the law

Yes, for the lottery and horse racing. At 18 you can buy Maryland Lottery tickets and bet on the races at the state’s tracks; its six casinos, their poker rooms and every licensed sportsbook, in person or online, are for players 21 and over.

Maryland has two ages. 18 covers the lottery and betting on horse races. 21 covers the casinos, poker and sports betting, and under-21s can’t go onto a casino gaming floor at all, even with an adult.

The Maryland Lottery and Gaming Control Agency runs the lottery and regulates the six casinos and sports betting; the Maryland Racing Commission oversees horse racing. Voters approved sports betting in November 2020, retail sportsbooks opened in December 2021 and mobile apps in November 2022.

Any further expansion needs a statewide vote. Bills for online casinos failed in 2024, 2025 and 2026, so the earliest a vote could come is November 2028.

Only sports betting, for bettors 21 and over on licensed apps. Maryland has no online casinos or online poker. Players 18 and up who want casino games, poker or sports betting online use the offshore casinos and sportsbooks we recommend.

They sit in a legal gray area. Maryland doesn’t license them, and its law says a person may not bet or gamble for money outside what it allows; breaking that rule is a civil offense with a fine of up to $500, or $1,000 above $100, not a crime. Federal law is aimed at the businesses that take bets rather than the players, and since the Supreme Court’s ruling in Murphy v. NCAA in 2018, each state has set its own sports betting rules.

The sites we recommend hold licenses from regulators abroad and have served Maryland players for years. Not every offshore site takes Maryland players, so check before you join.

18+ Casinos In Maryland

There are six retail casinos in MD that contain real money games for players aged 21 and older. Under-21s can’t go onto the gaming floor, even with an adult. Any change to the minimum age would require an act of the state legislature.

There are no online or mobile casinos offered domestically in MD. Each local casino is operated by a retail organization. There are no tribal casinos in Maryland: its tribes are recognized by the state, not the federal government, so they can’t open casinos under federal law.

The following brick-and-mortar casinos are open now to 21+ gamblers. Each location will vary slightly in what they offer. Real money games include slots, poker, off-track betting, sports betting, blackjack, craps, roulette, baccarat, and more.

Online Casinos In Maryland For 18 And Up

Maryland’s casinos can’t offer their games online. Bills to change that failed in 2024, 2025 and 2026, and because any gambling expansion in Maryland needs a statewide vote, the earliest one could reach voters is November 2028, almost certainly for players 21 and over.

For players 18 and up, the offshore casinos we recommend are licensed by regulators abroad and take Maryland players, with slots, blackjack, roulette and live dealer tables.

Casino Age In Maryland

You must be 21 to play at a Maryland casino, and under-21s aren’t allowed in the areas with slots or table games at all, even with an adult; only casino staff at work are exempt. The resorts’ hotels and restaurants outside the gaming floor are a separate matter.

Yes. Maryland’s six casinos are legal for players 21 and over, with slots, poker, blackjack, craps, roulette and baccarat, and most have a sportsbook. Three are full resorts with hotels: MGM National Harbor, Live! Casino & Hotel and Rocky Gap, where guests can also catch a show or a concert. None of the six can offer casino games online.

No. Maryland licenses no online casinos, and the bills to allow them have failed three years running. Next door, Delaware online casinos have run through the state lottery since 2013, but they too are for players 21 and over. Players 18 and up who want online casino games use the offshore casinos we link to here, with slots, blackjack, roulette, craps and live dealer games under one account.

Maryland Betting Apps

Maryland licenses sportsbook apps for bettors 21 and over; it has no licensed casino or poker apps. For players aged 18 and up, the offshore sportsbooks, casinos and poker rooms we recommend run in any iPhone, iPad or Android browser, with nothing to download and the same options as their desktop sites.
