Typically, a casino is a building where gambling games are played. There are many types of casinos and the games are varied. These include poker, blackjack, baccarat, slots, roulette, craps and a host of other games.

The word “casino” originated in Italy and has been used to describe gambling facilities over the years. Casinos are now legal in 40 states in the United States. In addition, there are legal casinos in many countries. These include Australia, France, Portugal, Finland and Britain.

Most casinos have security measures in place, such as cameras and security guards. These are meant to protect the casino from crime. However, a security guard can be overwhelmed by a variety of distractions.

Many casinos have specialized security departments that work together to ensure the safety of patrons and casino assets. These departments usually consist of a physical security force and a specialized surveillance department.

The specialized surveillance department is known as the “eye in the sky.” The department operates the casino closed circuit television system. It monitors casino games and statistical deviations in real time. The department also handles calls for assistance.

Traditionally, casinos are camera-shy, but this is no longer the case. Security cameras and catwalks are used to allow surveillance personnel to look directly down on the casino floor.

The casino also offers reduced-fare transportation to large bettors. Casinos typically offer free cigarettes to gamblers. They also have a “chip tracking” system that allows casinos to monitor exact amounts bet on minute-to-minute basis.
