What Is a Casino?

A casino is a building or room in which gambling takes place. It may also refer to a company that runs such an establishment, or the owner of such a building. The term may also be used to describe an establishment that offers certain types of live entertainment, such as stand-up comedy or a concert.

Modern casinos look more like a glamorous theme park than an old-fashioned gambling house, with musical shows, shopping centers and elaborate hotel accommodations. But casinos would not exist without games of chance, and the billions of dollars in profits they rake in each year come from patrons placing bets on dice, cards, slots and other machines.

While lighted fountains, restaurants and hotels attract the public, gamblers are the backbone of the industry. According to the American Gaming Association, about 51 million people—a quarter of all Americans over 21—visited a casino in 2002. That figure doesn’t include visitors to international casinos.

Gambling is a time-honored pastime that’s been around for millennia. It was practiced in many cultures, from the Ancient Mesopotamia to the Greeks and Romans and later by Napoleon’s France and Elizabethan England. Modern casinos have evolved from these early games, incorporating elements of traditional table games and exotic Far Eastern ones.

While most people play for fun, compulsive gambling is a serious problem that can destroy lives and bankrupt families. It also costs communities through higher crime rates, lower property values and a loss of jobs that could have been performed by addicts who were once casino customers. Ultimately, many experts believe that the net economic benefit of a casino is negative for a community.

Casinos make their money by imposing a built-in edge on every bet placed. This advantage can be very small (less than two percent), but over millions of bets, it adds up to a substantial profit for the casino. To counteract this edge, casinos offer free or discounted goods and services to “good” players. This can include free hotel rooms, dinners and tickets to shows. Some casinos even give away limo service and airline tickets to large bettors.

The most famous casino in the world is probably the Bellagio, which has featured in numerous movies and TV shows and is a must-see for visitors to Las Vegas. However, other casinos are also popular, including the Casino de Monte-Carlo in Monaco, the Casino Lisboa in Lisbon and the elegant spa town of Baden-Baden in Germany. Each has its own unique style that draws visitors looking for glamour, history or a bit of both.
