A casino is a facility for certain types of gambling. It is sometimes built near or combined with hotels, resorts, restaurants, retail shops, cruise ships, and other tourist attractions. Casinos can also host live entertainment such as concerts and stand-up comedy.
The word “casino” originally referred to a public hall for music and dancing in the 18th century, but it came to be used more generally to refer to any building or room where gambling games are played. The largest casinos in the world are located in Las Vegas, Macau, and Singapore. However, there are many smaller casinos around the globe. Some are housed in spectacular buildings designed by famous architects, while others are more modest structures. There are even a few floating casinos on rivers and lakes. Casinos earn billions of dollars a year from gamblers and provide jobs for thousands of people.
Because of the large amounts of money involved, security is a key consideration at most casinos. Employees have to be alert for patrons who try to cheat or steal, either in collusion with other players or independently. Cameras are routinely placed throughout the casino to monitor activities.
Because every game has a built-in statistical advantage for the casino, it is extremely rare for a casino to lose money on any given day. That virtual guarantee of gross profit allows casinos to offer big bettors extravagant inducements such as free spectacular entertainment, luxury hotel rooms, and reduced-fare transportation.
