What Is a Casino?

When many people think of casinos, they picture the flashy megaresorts that typify Las Vegas. These world-class casinos are more than places to gamble; they offer a complete luxury experience. The appeal is universal: high rollers, tourists, and people who simply enjoy a night of opulence.

Casinos are a major source of income for the companies, investors, and Native American tribes that own them. They also rake in billions of dollars each year for local and state governments. These profits are the result of both gambling and nongambling activities. In the United States, a casino falls under the North American Industry Classification System code 713210.

While some casinos have a traditional and elegant atmosphere, others are designed to be more modern. In general, casinos employ a combination of factors to motivate gamblers to spend money: the colors, sounds, and scents that are used in the gambling halls; the types of games offered; and the overall size of the gaming area.

In addition to creating an exciting ambiance, the best casinos have sophisticated systems for supervising game play. For example, in a game of roulette, computers monitor each spin and instantly reveal any statistical deviation from normal. In addition, in some casinos, betting chips contain microcircuitry that allows the house to oversee the amount of money wagered minute by minute.

Gambling has been a part of human culture for millennia. Archeological evidence of dice dates back to 2300 BC, and playing cards appeared in Europe around 800 AD. Today, the most popular casino game is blackjack, followed by poker and baccarat.
