What Is a Casino?

A casino is a gambling establishment where patrons can place wagers on various games of chance and sometimes skill. The word is derived from the Latin caino, meaning “bag” or “box.” Several states have legalized casinos, including Nevada and New Jersey. Casinos also are found in some American Indian reservations, which are exempt from state antigambling laws. During the twentieth century, casinos spread worldwide, and many European countries amended their gambling laws to permit them.

In order to attract customers and keep them gambling, casinos spend large amounts of money on color, sound, scents and other atmospheric enhancements. The noise, humming, flashing lights and the clang of coins dropping from slot machines are designed to stimulate the senses. Many people who go to casinos do so in groups. Some of the most popular casino games include poker, blackjack, baccarat and craps.

Casinos earn billions of dollars a year. Those profits are shared by owners, investors, and local, state and federal governments. In addition, some casinos are profitable because of a hefty commission paid by players to the house in games of skill such as keno and roulette. Most casino winnings, however, are subject to federal income tax, unless they are a lottery prize or are considered taxable gifts under applicable state law. Casinos must withhold federal taxes on these winnings if they are substantial. Some casinos may withhold additional state or local taxes. These withholdings must be reported to the IRS on a Form W-2G.
