What is a Casino?

A casino, also called a gambling house or a kasino in some jurisdictions, is a place where people can wager money on various games of chance. Casinos are most often built near or combined with hotels, restaurants, retail shops, cruise ships and other tourist attractions. They may also be incorporated into private estates. Some casinos host live entertainment such as musical performances or stand-up comedy acts.

Gambling is one of the oldest forms of entertainment in human history, dating back thousands of years. It was popular in ancient Mesopotamia, Greece and Rome. The modern casino industry is estimated to be worth billions of dollars and is a major source of revenue in many countries around the world.

Casinos spend a great deal of time and money on security. They use sophisticated surveillance systems to monitor patrons and games. These include catwalks suspended from the ceiling that allow security personnel to watch every table, change window and doorway at once; cameras mounted in the ceiling that can be directed at specific suspicious patrons; and “eye-in-the-sky” cameras with a view of the entire floor and the ability to zoom in on specific tables or slot machines.

In the early days of legalized gambling, casinos were controlled by organized crime gangs. But after real estate investors and hotel chains began to realize the potential profits, mob-controlled casinos were gradually phased out. Casinos are sometimes criticized for their negative economic impact on communities. Critics point out that the revenue from gambling shifts spending away from other forms of entertainment, and that the cost of treating problem gamblers and lost productivity due to addiction negates any economic benefits.
