What Is a Casino?

A casino is a building or room in which gambling games are played. The term may also refer to a group of gambling establishments or the industry that operates them. Casinos offer a variety of gaming options such as table games, slot machines, keno and bingo. Some casinos even feature top-notch hotels, spas and restaurants.

The term casino is most often used in the United States. However, the casino is a worldwide phenomenon and exists in many countries. The popularity of casino has led to the development of newer forms of the game, including online and mobile versions.

While music shows, lighted fountains, shopping centers and lavish hotels attract visitors, the billions of dollars in profits casinos make each year come from gambling on games like blackjack, roulette, craps, poker and baccarat. In fact, a casino without these games is not a casino at all.

Security at a casino begins on the floor, where casino employees keep their eyes on the action. Dealers watch for blatant cheating like palming or marking cards and dice, and they note patterns in betting that could signal a rigged game. Higher-ups monitor the floor with cameras positioned to cover every table, window and doorway.

In the past, mobsters controlled many casinos, but the threat of losing a license to operate at the slightest hint of mafia involvement has kept them out. Real estate investors and hotel chains have now taken over, and their deep pockets ensure that a whiff of organized crime will not affect their bottom line.
