A Casino is a gambling establishment where people can exchange money for chips and play games of chance or skill. Some casinos offer live entertainment shows. Most of these venues require customers to be of legal age and to abide by the rules and regulations of the establishment. Casinos earn billions each year for the companies, investors, and Native American tribes that own and operate them. The profits also benefit state and local governments, which collect taxes from the patrons.

Casinos use many tricks to attract gamblers and keep them gambling. They arrange the slot machines and tables in a mazelike way so that wandering visitors encounter them repeatedly and are enticed to try their luck. They make the environment noisy and opulent, with a mix of lights, bells, and whistles. The machine noises, especially the cling clang of coins dropping during payouts, are designed by computer to appeal to the senses and fit in with the general ambient noise.

Whether the casino is a megaresort in Las Vegas or a small town in the middle of nowhere, its primary goal is to make money. The mathematical odds are always against the player in games of chance, and the house gains an advantage from a percentage of bets made (called a “house edge”). In games where players compete against one another, such as poker, the casino earns a commission called rake.

While most Americans see casino gambling as acceptable for others but not for themselves, about a third of them visit such facilities. The most popular gambling destinations include the Las Vegas Strip and Atlantic City, but a growing number of smaller, more modest casinos are opening in towns across the country and even abroad.
