What is a Casino?

Casino is a building where gambling takes place, including games of chance and some that require skill. The establishment has a number of features that enhance the customer experience, such as restaurants and bars, entertainment, top-notch hotels, spas and meeting and convention facilities. It also has gaming options like blackjack, roulette and poker, as well as slot machines.

There is only one thing that is certain about casinos: They will always make money. Every game has a built in mathematical advantage for the house, which guarantees that it will win at least a small amount on most bets, and often much more. This edge can be very low, less than two percent, but over the billions of dollars that patrons gamble every year, it earns the casino a large profit. This edge is sometimes called the house edge, vig or rake, depending on the game.

Because of this virtual assurance of gross profits, casinos are very choosy about who they let play their games. Big bettors are often offered free spectacular entertainment, limousine transportation and elegant living quarters. Even lesser bettors are frequently given complimentary drinks and cigarettes while gambling and other inducements.

Something about gambling (probably the presence of huge sums of money) seems to encourage people to try and cheat, steal or scam their way into a jackpot, instead of winning through pure random chance. This is why casinos spend a large amount of time, effort and money on security. Elaborate surveillance systems include cameras that watch every table, window and doorway and can be directed by security workers in a separate room filled with banks of security monitors.
