What Is a Casino?

A casino is a gambling establishment for games of chance and often also offers other entertainment, such as live performances. In some countries, casinos are operated by governments and have formal rules and regulations. In others, they are private businesses with looser rules and regulations. Some casinos are located in resorts, and others are standalone businesses or are combined with other attractions, such as hotels and restaurants.

A casinos business depends largely on the profits generated by players gambling with cash or other assets. Most casino games have mathematically determined odds that give the house an advantage over the players, a figure known as the house edge. In some games with an element of skill, such as blackjack and poker, the casino earns a commission on the money wagered, known as the rake.

The sheer volume of money handled within a casino can motivate both patrons and employees to cheat or steal, either in collusion with each other or independently. This is why casinos spend a large amount of money and effort on security. Cameras and video monitors are placed throughout the casino to record all activities. In some casinos, elaborate surveillance systems provide a high-tech eye-in-the-sky that allows surveillance personnel to watch every table and window from a control room with banks of monitors.

While musical shows, lighted fountains, shopping centers and lavish hotel accommodations help draw in the crowds, casinos wouldn’t exist without games of chance such as slot machines, roulette, craps, baccarat, keno and blackjack that generate the billions in profit that casinos bring in each year. Despite their enormous profits, some studies suggest that casinos actually harm the economy of the communities they serve through the loss of spending on other forms of local entertainment and by the costs of treating compulsive gamblers.
