A casino, or gaming house, is a place where people can gamble and play games of chance. It also serves as a social gathering place. Some casinos offer a full range of entertainment, including stage shows and dramatic scenery. Many offer free food and drinks to keep patrons happy. Some even give out comps to “good” players—free hotel rooms, meals, tickets to shows and even airline and limo service.
There are more than 1,000 casinos worldwide, and most of them are located in the United States. The world’s best-known gambling venue, the Bellagio in Las Vegas, offers high-end dining and entertainment options, along with the usual range of tables and slot machines. The casino is perhaps best known for the dancing fountains that appear to be choreographed to music and are featured in the movie Ocean’s 11.
Although there are some games of chance that require skill, the majority of games are purely based on luck. Because of this, the house always has an advantage over players. This is called the “house edge.” Casinos have built-in advantages that ensure they, not their customers, will win in the long run.
Casinos employ a number of security measures to prevent cheating and theft. Many use cameras that can be adjusted to zoom in on suspicious patrons. They may also have a room filled with banks of security monitors where employees can watch the whole floor at once. In addition, dealers are required to keep their hands visible at all times, and table managers and pit bosses keep a close eye on each game, looking for blatant cheating like palming or marking cards.
