What Is a Casino?


A casino is a facility for certain types of gambling. It can be combined with hotels, restaurants, retail shops and other tourist attractions. It may also be known as a gaming house or gambling hall. A casino is most familiar to people as a place where they can play games of chance for money or other prizes, but it also has a variety of other entertainment options that make it a popular tourist destination.

Casinos make their money from the people who gamble there, and they need the visitors to come back. Besides offering a wide selection of games, they add amenities like musical shows and lighted fountains to draw in the crowds. They also hire mathematicians and computer programmers to calculate the odds of winning and losing, so that they can advertise their games accurately and not overstate their probabilities.

Because casinos handle large amounts of cash, they have many security measures in place to prevent cheating and theft. One obvious measure is the use of security cameras, but more sophisticated systems include “eye-in-the-sky” surveillance that can monitor every table, window and doorway at once. Casinos also rely on electronic systems to oversee the actual games themselves: betting chips with built-in microcircuitry allow casinos to keep track of the exact amount wagered minute by minute; roulette wheels and dice are monitored regularly to spot any statistical deviation from expected results.

In general, casino gamblers are middle-aged to older adults with above-average incomes. They are more likely to be female and married, and a larger percentage are college graduates than in the general population.
