A casino, also called a gaming house or gambling establishment, is an institution where people can play various games of chance and skill for money. Casinos can be found in many cities and towns in the United States and worldwide. Some casinos are standalone buildings, while others are located within hotels, resorts, and other types of tourist attractions.

Generally, casino games involve a high degree of luck and low skill, but some do have elements of strategy. The house always has an advantage in casino games, and this is known as the house edge or expected value (EV). Casinos can generate huge profits for the owners, operators, and gamblers. In addition, the casinos bring in billions of dollars each year for local governments through taxes and fees. However, critics argue that compulsive gambling is a major problem that causes people to shift spending away from other forms of entertainment and that the economic costs of treating addictions far outweigh any revenue generated by the casino.

Casinos focus on customer service and provide perks designed to encourage patrons to spend more, such as free items or discounts on meals, drinks, shows, and room rates. For example, during the 1970s Las Vegas casinos were famous for offering cheap travel packages and free show tickets to encourage gambling. In addition, most casinos offer “comps” to big spenders; these include free hotel rooms, meals, and slot play, and some even offer limo service and airline tickets.
