A casino is a gambling establishment that offers the excitement and thrill of risking money for winning big. Unlike Internet gambling and lotteries, casinos offer a social environment where patrons interact with each other. Casino games are usually conducted by live dealers and involve random numbers. Casinos are also known for their luxury accommodations, high-end restaurants and breath-taking art installations. They have become a major tourist attraction in cities worldwide, and many people visit for a special vacation or even as a form of entertainment like seeing the famous dancing fountains at the Bellagio in Las Vegas.

A gambler’s experience in a casino is largely determined by the design and atmosphere of the building, its location and its gambling options. The decor, lighting and sounds are designed to appeal to the senses. A casino can be bright and noisy with the clank of coins, bells and the whirring of slot machines to attract gamblers. The walls and floors are often colorful, often with a cheery red color, to stimulate the senses and encourage gambling. There is almost always noise and activity in a casino, with players shouting encouragement or betting on the outcome of a game. Alcoholic drinks are readily available and served to gamblers by waiters circulating throughout the gaming floor.

Until the late 1950s, most casinos in America were owned and operated by gangsters with deep pockets. Mob members provided the money and were involved in every aspect of casino operation, including hiring dealers and establishing their own rules of play. Real estate investors and hotel chains began to see the potential profits of casinos, and bought out many of the mobsters. This, combined with federal crackdowns on mob involvement in casinos, helped to keep legitimate casino owners away from the mafia and gave the industry a clean image.
