A casino is a gambling establishment that offers various forms of chance-based games. These include card games, dice, roulette, and other table games. Some of these games involve an element of skill, and others have mathematically determined odds that are uniformly negative to the player. In games such as blackjack and video poker that involve an element of skill, casinos earn money through a commission known as the rake.

In the United States, most casinos are commercial establishments licensed by state governments to offer certain types of gambling. In addition to casino games, most have restaurants and bars, and some even host live entertainment. Most casinos are also heavily secured, with security cameras and one-way mirrors that allow surveillance personnel to watch players and guests.

The precise origin of gambling is unknown, but it has long been a popular form of entertainment in many cultures and societies. It was practiced in Ancient Mesopotamia, the Roman Empire, Napoleon’s France, and Elizabethan England. Today, the world’s largest casinos are in Las Vegas and Macau.

The elegant spa town of Baden-Baden first became a playground for Europe’s elite 150 years ago, and its casino is considered by some to be the most beautiful in the world. Inspired by the baroque flourishes of Versailles, its red-and-gold poker rooms and dozens of blackjack tables are sure to impress. In addition to gambling, the resort’s facilities include a two-tier casino and an opulent hotel with three restaurants, a contemporary art gallery, and a flexible auditorium.
