A Casino is a building where various types of gambling games are played. Although gambling likely predates recorded history, the modern casino grew out of a need to bring a variety of gaming activities under one roof. In the United States, casinos are regulated by state law.

The modern casino is a sprawling complex of entertainment that often includes hotels, restaurants, non-gambling games rooms, bars and swimming pools. It’s not unusual for the largest casinos to be more than a small city in size.

In the world of casino games, slot machines, black jack, roulette and craps account for billions in annual profits. But casino patrons can also gamble on sports, horse racing and other events.

Some people are tempted to cheat and steal at casino tables, either in collusion or independently. To avoid this, casinos use many security measures. These range from simple cameras to elaborate surveillance systems that provide an “eye-in-the-sky” view of every table, window and doorway. Video tapes are constantly monitored and can be viewed after a crime or incident occurs.

A casino’s success is largely dependent upon its reputation. It needs to be a place where patrons feel comfortable and safe, yet have the opportunity to win money. But it also has to provide an atmosphere that attracts people who enjoy gambling, food and drink. The best known casinos boast spectacular decor, enormous size and an overwhelming number of games. Some even feature theaters, contemporary art galleries and other entertainment amenities.
