What Is a Casino?


A casino is a place where people gamble using games of chance and, in some cases, skill. A casino also provides restaurants, free drinks and stage shows to entice patrons to gamble. In addition, casinos provide security and other services to prevent illegal activity, such as counterfeiting chips or stealing credit cards. Casinos must spend a considerable amount of money on these security measures because they are often targeted by criminals.

Although many casinos offer free drinks and stage shows, they have to make a profit from the gambling activities of their patrons. To do this, they rely on mathematics and statistics to ensure that they have a positive expected value per visit (sometimes called house edge). They also employ mathematicians or computer programmers who manage various aspects of their operations. For example, some casinos monitor the exact amounts wagered on specific games minute by minute, and they may employ special equipment that electronically scours roulette wheels to discover any deviation from their expected statistical distribution.

Casinos are designed to be attractive and entertaining to the maximum number of potential customers, but they also must have strict rules about gambling. They must enforce rules about who can play, how much a player can wager and whether players are of legal age. They must also deal with issues such as a patron using a stolen credit card or being unable to pay his debts. In addition, they must protect their own assets by using cameras and other surveillance equipment to keep a watchful eye on what’s going on in the building.

Gambling is popular among many groups of people, and casinos must cater to a wide variety of tastes and budgets. For example, a low-end casino might feature a few blackjack and roulette tables and a few slot machines, while a high-end casino might have a variety of poker tables and a luxurious hotel. The high-end casinos are often decorated in elegant, tasteful and lavish styles.

In the United States, patrons spent over $319 million in casinos in 2005, which was seven times more than they did in 1990. This makes casinos one of the most popular leisure activities in the country, ahead of baseball and other professional sports and Broadway shows. In addition, the casino industry is expanding in other countries around the world, especially on American Indian reservations that are exempt from state anti-gambling laws.

Because a casino’s profitability depends on the volume of customers, it must constantly focus on customer service. Its perks include comping customers, which means giving them free items such as show tickets and hotel rooms. This is done to keep customers happy, which translates into more money spent on the tables. For example, a person who loses $1,000 playing blackjack might be given a $500 hotel room or a few free dinners. This might not bring him back to the table, but it will make him feel as if his experience at the casino was worth it.
