What is a Casino?


The modern casino is a glitzy, noisy, smoke-filled place where patrons can play games of chance for money. It is a business that makes billions of dollars in profit every year, and it has a number of built-in advantages that ensure its profitability. Every game has a mathematical expectancy, or house edge, that defines how much the casino will win on average. Casinos hire mathematicians and computer programmers to work out the expected return for each game, so they can budget their capital requirements.

Casinos try to give their patrons a five-star experience. Luxury suites, clubs, concerts, swimming pools, and golf courses are all part of the casino menu. The casinos also make sure their gambling spaces feel comfortable and safe, with a variety of surveillance systems. These include hidden cameras and catwalks that allow security personnel to watch the activities of slot machines and table games through one-way glass.

Gambling is a popular pastime around the world, and casinos are popping up everywhere from Las Vegas to the remote desert regions of Nevada. During the late 20th century, most of Europe changed its laws to permit casinos, and even formerly communist countries like Cuba opened up their casinos. Casinos are also common in American cities, and on Indian reservations, where state antigambling laws don’t apply.

Most casinos offer a wide variety of gaming options, including slots, table games, and card games such as baccarat (known as chemin de fer in France), blackjack, and trente et quarante in the French-speaking parts of the United States. Some also have poker rooms. Most casinos take gambling addiction seriously, and train employees to spot problem gamblers. They also display brochures for Gamblers Anonymous and other treatment options prominently in their premises.
