What Is a Casino?

A casino is a facility for gambling, including card games and other entertainment. Its customer base is primarily composed of professional gamblers and recreational players, although it also includes tourists and local residents. In addition to gaming tables, casinos often contain restaurants and bars, and offer a variety of other services such as convention space, gift shops, and even wedding chapels. A number of the more prestigious casinos are owned by cities or regions and serve as regional tourist attractions.

Because large amounts of money are handled within a casino, both patrons and staff may be tempted to cheat or steal, either in collusion or independently; for this reason, most casinos have security measures in place. These include cameras in the gambling areas, which can be monitored by security personnel. Additionally, most casinos prohibit players from talking with each other while playing, and require that their cards be visible at all times. In some casinos, a catwalk in the ceiling allows security personnel to look directly down on gamblers from above.

A casino’s profitability depends on its ability to attract a sufficiently large number of customers, who generate income through gambling activities. In the United States, this income is generated primarily by slot machines and video poker, with a smaller share coming from table games such as blackjack and baccarat. In general, a casino’s advantage over its customers is mathematically determined and known as the house edge. Casinos often mitigate this advantage by offering comps to regular customers, such as free food or drinks.
