A casino, also known as a gambling house or a gaming establishment, is an establishment for certain types of gambling. Casinos are most often built near or combined with hotels, restaurants, retail shops, and other tourist attractions. They may also be found in the vicinity of military bases and cruise ships. The largest casinos in the world can be found in Macau, Oklahoma, and the Philippines.

Gambling in its various forms, from the casual with a bookmaker to a full-blown casino experience, has been part of human culture for millennia. Evidence of betting has been found in China as early as 2300 BC, and dice were first used in Rome in 500 AD. In modern times, the popularity of casino games such as roulette, blackjack and poker has skyrocketed.

Some of the most opulent casinos on earth are found in cities around the globe, where luxury and decadence are elevated to an art form. The elegant spa town of Baden-Baden was first a playground for European royalty 150 years ago, and the opulent Hotel Grand Lisboa in Macau is crowned with the largest LED dome on the planet, consisting of more than a million lights.

Some of the best online casinos offer a wide selection of casino games, including slots and table games. They also feature a variety of payment options, such as PayPal, Skrill and Neteller. A good casino will be able to offer support in multiple languages, and should have a 24/7 live chat service.
