Why Do Cruise Ship Casinos Close in Port?
It comes down to jurisdiction, not company policy. A cruise ship follows the gambling laws of whichever waters it’s currently in. While docked, that means the local port’s laws apply, and most countries don’t permit a foreign-flagged ship to run a casino inside their territorial waters or while tied up at their dock. Once the ship pulls away and crosses into international waters, typically 3 to 12 nautical miles offshore depending on the country, the casino falls back under maritime and flag-state rules instead, and it can legally reopen.
There’s a commonly repeated theory that ports also want to protect their own local shops and casinos from onboard competition while the ship is docked, and several cruise crew members have said as much anecdotally, though the legal mechanism is genuinely the jurisdiction rule above.
When Is the Casino Open on a Cruise?
Most casinos open once the ship clears the distance limit from shore and stay open until the early hours, commonly 9 or 10 am to 2 or 3 am on sea days. The exact hours vary by cruise line and ship.
Alaska cruises work a little differently. Because ships there often hug the coastline for the whole itinerary, some routes never actually reach international waters. Cruise lines get an exception here: the casino can open 3 miles after leaving one Alaska port and stays open until 3 miles before reaching the next, regardless of distance from land. It’s also why the final night on a Victoria-to-Seattle route often sees the casino close early and never reopen; the ship goes straight from Canadian into U.S. waters without crossing international water at all.
The Ports Where the Casino Stays Open
A few destinations have negotiated exceptions that let the casino run even while docked, because the port itself issues a gaming license to the ship:
- Bermuda, typically 9pm to 5am while in port
- Nassau, Bahamas, typically 7pm to 3am while in port
- Private cruise line islands, such as Royal Caribbean’s Perfect Day at CocoCay, where the casino can stay open all day
Outside these specific cases, the rule holds: no international waters, no casino.
What Games Will You Actually Find?
Cruise ship casinos mirror land-based ones in scale-down form. Expect the same core lineup:
- Slot machines, including penny slots and video slots, usually the largest section by floor space
- Blackjack, roulette, and craps
- Poker variants like Three Card Poker and Ultimate Texas Hold’em, and sometimes baccarat
Table minimums usually start around $5 to $10, with a few $25 tables offering slightly better rules for bigger stakes. Most ships also run daily slot, blackjack or poker tournaments with modest entry fees.
One practical detail: cruise casinos generally run on a cashless system tied to your onboard account rather than cash and chips, which is convenient but easy to lose track of; it’s worth setting a personal limit before you start.
A Few Things Worth Knowing Before You Play
Age requirements typically follow the departure country: 18 on most U.S. and Canadian sailings, 21 for Alaska routes. Smoking is still permitted in designated casino areas on most mainstream lines, one of the last onboard spaces where that’s true. And if you’re a U.S. citizen or resident, cruise casino winnings are taxable the same as any other gambling win; a jackpot of $1,200 or more triggers a W-2G form, and the cruise line won’t always report it for you, so keep your own records.
What to Play Online Instead While You Wait
Port days, sea-day downtime, or simply not being near a cruise at all, this is exactly where live dealer casino games close the gap. The same table games running on the casino deck- blackjack, roulette, poker variants- are available online with real dealers streaming in real time, no waiting for international waters required.
If you enjoy the wheel-based excitement of a ship’s game show nights, our Crazy Time strategy guide and Monopoly Live strategy guide cover Evolution’s live wheel games in full detail. Prefer the classics, our live blackjack strategy guide and Lightning Roulette guide are built the same way. And if you’re comparing where to actually play, our best crypto casinos list and fast payout casinos guide are good starting points, especially since online payouts don’t run on a ship’s internal review schedule.
Final Thoughts
The closure itself isn’t a cruise line quirk; it’s a legal requirement tied to whichever waters the ship is sitting in, and it lifts the moment the ship reaches international waters again. Know the schedule for your specific itinerary, watch for the handful of exceptions like Bermuda and Nassau, and if the tables are dark on port day, live dealer games online cover the same ground without needing to wait for the anchor to lift.
