Casino questions, answered

The same handful of questions come up before every casino trip: how old you have to be, whether they will want your passport, what happens to your winnings at tax time, whether you can smoke, and what to wear. The answers differ by country, so each one below is compared across every jurisdiction we have published rules for — 64 of them, reviewed August 2026.

Questions people ask before a casino trip

How old do you have to be to gamble in a casino?The minimum casino age is 18 across most of Europe, 21 in the United States and Macao, and 20 in New Zealand and Japan. Belgium, Estonia, Lithuania, Greece and Cyprus are the European exceptions at 21.Full comparison →Do you pay tax on casino winnings?In most of Europe, Canada, Australia and Macao, casino winnings are not taxed in the player's hands — the operator is taxed instead. The United States is the significant exception: wins above set thresholds are withheld at 24%, and non-residents at 30%.Full comparison →Can you smoke in a casino?Almost every country bans smoking on the casino floor and confines it to a sealed room or an outdoor terrace. Nevada is the best-known exception, where smoking is still permitted at the tables and machines.Full comparison →Do you need ID to enter a casino?Yes, almost everywhere. Continental European casinos go further than a doorman's glance: France, Germany, Spain, the Netherlands, Poland and others register every entry and screen it against a national self-exclusion register.Full comparison →What should you wear to a casino?Smart casual clears the door almost anywhere. The dress codes that are still enforced sit in the historic European table rooms — Monte-Carlo, Baden-Baden, Venice, Estoril and London's Mayfair clubs — and they tighten after 20:00.Full comparison →Who regulates casinos in each country?Casino licensing sits with a national regulator in most of Europe, and with states or provinces in the United States, Canada, Australia, Argentina and Spain. A regulator's public register is the only reliable way to confirm a venue is licensed today.Full comparison →Which country has the most casinos?The United States has more casinos than any other country by a wide margin, followed by France and Germany. The ranking below counts every venue in this catalog with a verifiable location.Full comparison →Which casinos are open 24 hours?Round-the-clock opening is a North American habit more than a global one: most casinos in Nevada and along the US river markets never close, while European casinos typically run afternoon-to-late-night hours set by their licence.Full comparison →
