A casino, or gambling establishment, is a place where patrons wager money on games of chance or skill. In the United States, casinos are usually located in commercial or resort hotels and offer a wide variety of entertainment choices for their guests. They are typically equipped with gaming tables, slot machines, and other gambling apparatus. Some casinos also feature restaurants and live performances.

Gambling has been a part of human culture for millennia. The earliest evidence dates to 2300 BC China, when wooden blocks were used in games of chance. Dice appeared in Rome in 500 BC, and playing cards followed soon thereafter. Modern casinos have adapted to reflect changes in society and the technology available, but their basic principles remain unchanged.

In modern casino settings, players bet against the house and are often given a number of inducements to encourage them to spend more than they can afford. These may include free spectacular entertainment, luxury transportation, and elegant living quarters. In games of chance, the casino’s mathematical expectation of winning is uniformly negative, or, in other words, its “house edge.”

Some casinos employ cutting-edge technology to monitor their game play and improve their odds of success. For instance, some use microcircuitry in their betting chips to track the amount of money wagered minute-by-minute, enabling the casino to detect any deviation from its expected value. Other technologies allow for electronic surveillance of the roulette wheel and dice to detect any abnormalities that might affect the outcome of a game.
