What Is a Casino?

A casino is a building that is owned and operated by a person or group of people who allow guests to gamble. They are often regulated by the state in which they operate. Modern casinos are designed like indoor amusement parks and offer a variety of games that include slot machines, black jack, roulette, and keno. These games provide the billions in profit that the United States casinos rake in every year. It is very rare for a patron to win more than the casino can afford to pay, thus making gambling a mathematical game that gives the house an edge over the players.

The first government-sanctioned gambling house was the Ridotto in Venice in 1638, and this marked the birth of the casino. This early casino had many rooms with primitive card games, and it allowed a certain class of society to gamble and socialize without the risk of being caught. The idea spread throughout Europe as more and more people thought of the concept or copied it from the Italians.

In the twentieth century, the casinos became more choosy about who they accepted as patrons. They aimed their promotional efforts at high rollers, who gambled in special rooms that were isolated from the main casino floor and often had the stakes in the tens of thousands of dollars. These high rollers made up a large percentage of the gross profits, so the casinos lavished them with free spectacular entertainment, luxurious living quarters, reduced-fare transportation, and other gifts.

Today, a casino is often the destination of vacationers who enjoy the excitement of gaming and the luxury of a five-star hotel. It is also a popular venue for birthday and anniversary celebrations, and it is very common to see children and families at a casino. The casino industry has a very strong marketing and advertising campaign that promotes the image of the gaming room as being a fun place for the entire family.

Despite the glamorous lights and loud music of some casinos, there are strict rules of behavior for patrons. In addition to security guards, cameras are frequently used in casinos for surveillance purposes. The high-tech “eye in the sky” systems can be adjusted to focus on suspicious patrons by security personnel in a separate control room. In 2008, 24% of American adults had visited a casino at some time. Most of these were women over forty-five who lived in a household with an above average income. The majority of them were high-rollers, who spent a lot of money on table bets and hours at slot machines. They were rewarded with comps, such as free food and drinks, hotel rooms, tickets to shows, limo service, and airline tickets. The rest of the visitors were casual or occasional gamblers. The majority of them had no college degree. This compared with about 20% of Americans in 1989.
