A casino is a place where people gamble on games of chance. These gambling establishments can be massive resorts, or even cruise ships or truck stops that feature gaming tables and machines. Many casinos also have restaurants, bars, shops and other amenities. Casinos generate billions in profits each year for the companies, investors and Native American tribes that own them. Local and state governments often reap substantial taxes from casino operations as well.

Casinos rely on a variety of tricks to attract customers and keep them gambling. They offer food and drinks at low prices, stage shows with elaborate themes, and a wide array of gambling activities. But no casino can function without the games themselves, which are the source of the billions in annual revenues that casinos bring in.

The most popular games include poker, blackjack, roulette, craps, and slot machines. Most casinos have variations of these, plus a number of traditional Far Eastern games like sic bo, fan-tan and pai gow. In addition to these staples, casino owners try to differentiate themselves from competitors by offering other luxuries.

For example, some casinos use bright and gaudy colors to stimulate the senses, while others discourage patrons from leaving by removing clocks from the walls. Security is another important aspect of a casino. Elaborate surveillance systems provide a high-tech “eye-in-the-sky” view of each game area and can be adjusted to focus on suspicious patrons by security workers in a separate room filled with banks of monitors.
