How Old Do You Have to Be to Gamble? Age and ID Rules Explained

The short answer is 18 in most of the world and 21 in most American casinos. The fuller answer depends on the country, sometimes on the state or province, on the type of game and occasionally on the venue itself. A birthday that counts at home may not count at the door abroad, so anyone planning a casino visit, a cruise with a gaming room or a holiday flutter should check the rule where they will actually be playing.

Why the limits are not the same everywhere

A gambling age is set by whoever licenses the activity. In federal countries that is often a state or a province rather than the national government, and lawmakers frequently treat casinos differently from lotteries, bingo halls or racetracks. Alcohol rules play a part as well: where drinks are served freely on the gaming floor, matching the casino age to the drinking age keeps one check at the door instead of two.

The result is a patchwork. Two neighbouring states can set different limits, and a single resort can admit an 18-year-old to its bingo hall while sending the same guest away from the blackjack tables.

Typical age limits at a glance

Limits get revised from time to time, so read a table like this as a starting point and confirm the current figure with the venue or the local regulator before setting off.

The United States: mostly 21, with exceptions

Nevada, New Jersey and most other states with commercial casinos set the floor at 21. Some tribal casinos admit players from 18 under the terms agreed with their state, which is why a road trip can cross from a 21 venue to an 18 venue within an hour. Lottery tickets and scratch cards are usually sold from 18, though a few states set that limit higher too.

Under-age visitors can normally walk through a casino to reach a restaurant, a show or the hotel lifts, but they may not stop at a machine or stand behind a parent at a table. Security staff take this seriously, and so do the regulators who license the venue.

One consequence surprises people: if an under-age player slips past the checks and lands a big win, the casino generally will not pay it. Getting through the door does not turn an invalid bet into a valid one.

Canada, the UK and the rest of Europe

Canada's provinces set their own limits, which produces a split between 19 in most of the country and 18 in Alberta, Manitoba and Quebec. In Great Britain the age is 18 for casinos, betting shops, bingo halls and, since 2021, the National Lottery as well, which used to sell tickets from 16.

Continental Europe mostly uses 18, but casino entry sits at 21 in a few countries. Some places also treat their own residents differently from visitors: citizens of Monaco, for example, may not gamble in the principality's casinos at all, while foreign guests of age are welcome. The historic casinos of Europe tend to check ID at reception rather than at the tables.

What ID casinos ask for

• A passport is accepted almost everywhere and is the safest document to carry abroad.
• A national identity card works across much of Europe.
• A driving licence is the usual document in North America; some European casinos take one, others do not.
• Photocopies and photos on a phone are rarely accepted.

Many European casinos register every guest at the entrance, scanning the document and sometimes taking a picture. In American casinos the check is more likely to come at the edge of the floor, at a table when a dealer is unsure, or at the cashier when a large amount is paid out. Bigger cash-outs bring identity rules of their own, explained in our walk-through of the casino cage.

Online play works on the same principle

Licensed online casinos and betting sites must confirm a customer's age as well, usually before money can be deposited or withdrawn. The limit that applies is the one where the player is located, not where the operator is based, and an account opened with false details can be closed with its balance withheld.

Common questions

Can an 18-year-old gamble in Las Vegas?

Not in a casino. Nevada's gambling age is 21 for every game on the floor, slot machines included, and the same applies at the machines found in supermarkets and the airport.

Does a cruise follow the law of the home port?

The cruise line sets its own policy, which often depends on the itinerary. Our guide to cruise ship casinos covers how those rules work at sea.

Is the age for roulette different from the age for slots?

Inside one venue the limit is normally the same for every game. Before a first visit, reading up on a single table such as how roulette is played makes the evening calmer than learning the rules with chips already down.

Reaching the legal age opens the door; it does not make gambling a source of income. Decide on a spending cap before the trip, check the local rules where you will be, and if staying inside that cap starts to feel hard, the ideas in balancing fun with caution are a sensible next read.
