What Is a Casino?


A casino is a gambling establishment that provides customers with games of chance. This includes traditional casino games like blackjack, craps, roulette and baccarat as well as video poker and slot machines.

The term “casino” is used to describe a variety of gaming facilities, including large resorts and small card rooms. It is also used to refer to riverboats that operate in rivers across the United States.

Casinos make money by offering customers games with a mathematically determined advantage, called the house edge, over players’ expected value. This advantage, often expressed as a percentage of the player’s total bets, allows casinos to make more money than they would have otherwise.

In some games, such as video poker, the casino also takes a commission, known as the “rake,” from the game’s players. This can be a significant portion of the money earned by the casino.

Security at casinos is extensive. Dealers keep close tabs on each table and patron, ensuring that bets are correct and making sure there are no blatant cheats. Elaborate surveillance systems include cameras in the ceiling that change windows and doorways to focus on suspicious patrons.

Other features that add to the casino experience are restaurants, bars, shops and spas. In addition, there are performance venues where pop and rock bands perform for guests.

There are hundreds of casino locations around the world. Some are large resorts in Las Vegas, while others are smaller neighborhood casinos. The popularity of casino gambling is growing and new ones are constantly opening.
