What Is a Casino?

A casino is a public room where gambling games (such as roulette, baccarat, blackjack, poker, and slot machines) are played. It may also refer to a private club which hosts such games for members only.

Gambling is a common form of entertainment that has existed in most societies throughout history. Some of the oldest known games include dice, keno, and bingo. Modern casino gaming has developed from these roots to incorporate various aspects of chance and skill. Casinos typically feature multiple gambling options and can be combined with hotels, restaurants, retail shops, and other entertainment venues.

The majority of casinos offer a variety of table games, including card games such as poker and blackjack, dice games like craps and roulette, and wheel games such as baccarat. Some also have electronic gaming devices and arcade machines. Most of these games require the players to interact with each other, either directly as in poker or roulette, or indirectly through a dealer as in blackjack and baccarat.

A casino’s environment is designed to encourage gambling by promoting noise, light, and excitement. Many casinos use bright, often gaudy floor and wall coverings that are meant to stimulate the senses. Gamblers are encouraged to shout out encouragement, and waiters circling the casino offer drinks and food. Some casinos have no clocks in the rooms, because they want gamblers to lose track of time and stay longer.

Some casinos cater to high-stakes gamblers and have special rooms for them, away from the main gaming area. These high rollers are expected to spend tens of thousands of dollars or more, and casinos reward them with comps such as free suites, meals, and other prizes.
