If you’re planning a visit to Las Vegas, it’s important to understand the rules around gambling. The legal age for most forms of gambling in Nevada, including the city of Las Vegas, is 21. This applies to slot machines, poker, blackjack, roulette, and sports betting.
Knowing this age limit can help you plan your visit and avoid confusion at casino entrances. Casinos strictly enforce these rules, and identification is required to enter gaming areas.
In this guide, we’ll explain the age requirements for some different venues and situations, including airports and general casino access, so you can better understand what is and isn’t allowed before your trip.
In Las Vegas, anyone under 21 is not legally permitted to gamble. This rule is consistent across all casinos and gaming venues in Nevada.
Games that involve chance, such as slots, poker, and table games like blackjack or roulette, are considered gambling under state law. Sports betting, whether in-person at a sportsbook or via certain authorised kiosks, also requires participants to be at least 21.

Casinos are careful to check identification at entrances and before accepting any bets. Acceptable forms of ID include a passport, driver’s licence, or other government-issued photo identification. Even if you are 20 years and 11 months old, you are not allowed to gamble in any licensed casino or venue in Las Vegas.
If you arrive in Las Vegas by air, you may notice slot machines and other gambling options at McCarran International Airport (now officially Harry Reid International Airport). The same rules that apply in city casinos also apply at the airport. You must be 21 or older to play any slot machine or place any wager.
Airport security and casino staff may check your ID before you access the machines. This is part of Nevada’s strict enforcement of gambling laws to ensure underage individuals do not participate in gaming activities. Even though these machines are convenient, the age requirement is consistent with the rest of the city.

If you are under 21, you are not allowed to remain in or near any area of a casino where gambling takes place. This includes slot machines, table games, poker rooms, and sportsbooks. Nevada law prohibits anyone under 21 from being present in gaming areas, even if they are accompanied by an adult.
However, you can access non‑gaming areas of a casino, such as restaurants, shops, hotel rooms, and public walkways. Casino staff monitor entrances to gaming floors and may direct under‑21 visitors away from gaming areas to comply with the law. Even briefly stopping near a table or machine can be considered a violation, so movement through the casino must avoid these sections.
No. Anyone under 21 is not legally permitted to gamble in Las Vegas. All forms of gaming, including slot machines, table games like blackjack and roulette, poker, and sports betting, require participants to be at least 21 years old.
This age restriction applies across all licensed gaming establishments in the city, including casinos and airport slot machines. Attempting to gamble while under 21 can result in being refused entry or being asked to leave the premises. Nevada law does not provide any exceptions for under-21s, even if accompanied by an adult.

For adults based in the UK, online casinos such as Dream Jackpot provide access to a variety of slot games that are themed around Las Vegas. These are regulated under the UK Gambling Commission (UKGC), and players must be 18 or older to participate.
Online slot games use Random Number Generators (RNGs) to determine outcomes, meaning results are entirely based on chance. Payout potential, probabilities, and game rules vary depending on the software and game type. It is important to read the rules and understand that winnings are never guaranteed.
Responsible Gambling Reminder:
Gambling is an activity that involves chance, and any winnings can never be guaranteed. Players should set personal limits on time and money spent, and take breaks if needed. Always ensure you are of legal age for the type of gambling you choose.
