Minimum Age to Gamble at Sea
The minimum age to gamble on a cruise ship is 18 years old on most cruise lines, though some require you to be 21. The exact age depends on which cruise line you book with and sometimes on which country the ship is registered in. Royal Caribbean, Carnival, and Disney Cruise Line all set their own policies, and these policies can differ between their ships.
Age verification happens at the casino entrance. You will need to show a valid photo ID — a passport, driver's license, or state ID card. Cruise staff check IDs before letting anyone into the gaming area, and they check again if you approach a table or slot machine. There is no way around this step.
If you are under the minimum age for your cruise line, you cannot enter the casino at all, even to walk through or watch. The casino is a restricted area for minors on every major cruise line.
Key Takeaways
- Most cruise lines require you to be at least 18 years old to gamble, though some require 21 — check your specific cruise line's website before you book.
- You must show a valid photo ID at the casino entrance, and staff will verify your age before you can enter the gaming area.
- The casino is completely off-limits to anyone under the minimum age; you cannot enter even to observe.
- Age requirements can vary by ship within the same cruise line, so confirm the policy for your exact sailing.
- Gambling losses at sea are not covered by consumer protections that explore on land in most U.S. states.
Age Rules by Major Cruise Line
Royal Caribbean requires you to be 18 years old to gamble. This applies to all their ships, including the newest ones. You can gamble on sea days and when the ship is in international waters, but not when docked in U.S. ports.
Carnival Cruise Line also sets the minimum at 18 years old across their fleet. Like Royal Caribbean, gambling is not available when the ship is in U.S. ports.
Disney Cruise Line does not operate a casino at all. Their ships have no gambling, so age is not a factor for this activity.
Norwegian Cruise Line requires you to be 18 to gamble on most ships. Some of their older vessels may have different rules, so check your specific ship before sailing.
Princess Cruises sets the minimum at 18 years old. Their policy applies to all ships in the fleet.
If you are sailing with a smaller or international cruise line, contact the cruise line directly to confirm their age requirement. Policies can change, and some lines operate under different maritime laws depending on where they are registered.
What Happens When the Ship Is in U.S. Waters
When a cruise ship is docked at a U.S. port or in U.S. territorial waters, the casino closes. Federal law prohibits gambling in U.S. waters except under specific circumstances that cruise ship casinos do not meet. This means the casino will be shut down during port days in places like Miami, New York, or Hawaii.
The casino reopens once the ship leaves U.S. waters and is in international waters — typically a few hours after leaving port. If your cruise includes multiple U.S. port stops, the casino will close and reopen multiple times during your sailing.
Some cruises that visit only U.S. ports (for example, a short cruise from Florida that stays in Florida waters) may not have a functioning casino for the entire trip. If gambling access matters to you, check the itinerary and ask the cruise line whether the casino will be open during your specific sailing.
Types of Gambling Available on Ships
Cruise ship casinos offer slot machines, table games like blackjack and roulette, poker rooms, and sometimes bingo. Bingo often has a lower age requirement — some cruise lines allow passengers as young as 16 or 18 to play bingo even if the casino minimum is 21. Ask at the bingo desk about the age rule for that specific game.
Sports betting, online gambling, and betting on horse racing are not available on cruise ships. The casino offers only the games listed above.
Slot machines and table games operate 24 hours a day when the ship is in international waters, though some cruise lines close tables during very slow hours. Poker rooms and bingo have set schedules that are posted in your cabin and on the ship's app or daily program.
Bringing Minors on a Cruise with a Casino
If you are traveling with children or teenagers under the gambling age, they cannot enter the casino under any circumstances. This includes not being able to walk through the casino to reach other parts of the ship, if the casino is in the way.
Most modern cruise ships have alternate routes around the casino, or the casino is positioned so that passengers do not need to pass through it. If you are concerned about your route to other areas of the ship, ask at the front desk when you board.
Minors can use other ship amenities — pools, restaurants, entertainment venues, and shops — without restriction. The casino is the only area that is completely off-limits based on age.
What to Know Before You Gamble
Cruise ship casinos operate under maritime law, not state law. This means consumer protections that exist on land — such as problem gambling resources or dispute resolution processes — may not explore the same way at sea. If you have a dispute with the casino or believe you have been treated unfairly, your options for recourse are limited.
The house edge on cruise ship games is the same as in land casinos — the odds favor the casino, not the player. Slot machines, blackjack, roulette, and other games are designed so that over time, the casino makes money and players lose money on average. Gambling should be treated as entertainment you pay for, not as a way to make money.
If you plan to gamble, set a budget before you board and stick to it. Bring only the cash you are willing to lose. Do not use credit cards or ship credit to gamble, as this can lead to debt that follows you home.
Frequently Asked Questions
Can I gamble if I am 18 but my cruise line requires 21?
No. If your cruise line's policy is 21, you must be 21 to enter the casino. Age requirements are strictly enforced, and there are no exceptions. If you are unsure of your cruise line's rule, contact them before you book your cruise.
What if I forget my ID at my cabin?
You will not be allowed to gamble without a valid photo ID. You must go back to your cabin to retrieve it. Cruise staff will not let you into the casino without proof of age, even if you are a regular passenger or have gambled on the ship before.
Can teenagers watch people gamble in the casino?
No. The casino is a restricted area for anyone under the minimum age. Minors cannot enter the casino for any reason, including to observe or accompany an adult.
Does the casino close on sea days?
No. The casino operates 24 hours a day when the ship is in international waters, regardless of whether the ship is at sea or docked at a port outside the U.S. It only closes when the ship is in U.S. waters or U.S. ports.
Can I gamble on a cruise that never leaves U.S. waters?
No. If the entire cruise stays in U.S. waters, the casino will be closed for the entire trip. This applies to some short cruises from Florida and other U.S. ports. Check the itinerary and contact the cruise line to confirm whether the casino will be open during your sailing.
