A casino (also called a gambling house or a gaming establishment) is an establishment for certain types of gambling. In the United States, casinos are primarily places where people can gamble in games of chance or skill. Some casinos also offer live entertainment and meals. Casinos can be found in many cities and towns, including those that are primarily tourist destinations. They may also be combined with hotels, resorts, restaurants, shopping, and other attractions.

Modern casinos are often large and luxurious, and they feature a wide range of games that appeal to all types of gamblers. Some of the most popular games include slot machines, roulette, blackjack, and baccarat. Many casinos have a high focus on customer service and provide perks such as comps to attract new customers and reward existing ones.

Gambling has been part of human culture for millennia, with evidence dating back as far as 2300 BC in China. It was followed in the 1400s by a variety of card games and in the 1600s by the game that would become known as blackjack.

Casinos are most widely spread in the United States, where they are legal under state law. The first legally licensed casino opened in Nevada in 1931, and other states soon followed suit. The industry has grown rapidly since then, and the Las Vegas economy is largely dependent on the casinos.
