What Is a Casino?

A casino is a gambling establishment, often combined with hotels and resorts or located in the entertainment district of a city. Some casinos also offer live entertainment such as concerts and stand-up comedy, or offer dining and shopping options. Some casinos are also known for their celebrity chefs.

Some casinos are built into hotels and resorts while others are freestanding. Some have large gaming floors while others feature a combination of table games, slots and electronic gaming machines. Many casinos have restaurants, non-gambling game rooms, bars and swimming pools. Those in the Las Vegas area are notorious for their elaborate hotel-casino complexes with their giant pyramids, towers and replicas of famous landmarks.

While a casino’s main purpose is to earn money from patrons by offering games of chance, some also offer a little skill (like blackjack). All casinos, however, have built in advantages that ensure the house will win over the long term, even if the players are winning on any given day. This advantage is called the house edge, and while it may be as low as two percent, it adds up over millions of bets.

To offset this edge, casinos often give out “comps,” or complimentary items, to big spenders. These can include free shows, hotel rooms and transportation. They are designed to encourage gamblers to spend more money, and the more they do, the better the comps they get. Casinos are also highly secure, with surveillance personnel monitoring everything from the games to the people who play them. They have catwalks that allow them to see through one-way glass directly down on the tables and slot machines.
