A casino is a public place where gambling is a popular activity. This is the main business of a casino, and in modern times, casinos often feature free gambling devices and restaurants. In addition to gambling tables, casinos sometimes also feature stage shows and dramatic scenery. While these luxuries are generally expensive, less extravagant establishments can still qualify as a casino. In addition to the entertainment aspect, casinos are also a source of revenue for the principality of Monaco.
Many casinos have elaborate surveillance systems, so that security personnel can keep an eye on their patrons. These cameras are positioned throughout the casino, watching each table and window. They can even be adjusted to focus on suspicious patrons, and video feeds are recorded for later review. Casinos also have computer chips that determine how much a player wins in a slot machine. Luckily, there are no employees on the slot floor to catch anyone in the act of stealing money.
In the past, casinos were operated by gangsters, but as the casino industry became more reputable, real estate investors and hotel companies began buying up casinos from mobsters. Today, Donald Trump owns a number of casinos. The Hilton hotel chain is another notable example of this. Both of these companies bought up casinos and started running them without mob involvement. In addition to this, recent crackdowns by the government and the threat of losing a gaming license have discouraged the involvement of the mob in casinos.
