What is a Casino?

A casino is a place where people can gamble, play games of chance and win money. The word derives from the Italian casona, meaning “house.” Casino gambling has spread throughout the world, although most states still prohibit it or limit it to riverboats and Indian reservations. Most casinos feature a variety of gaming and entertainment options, including table games like blackjack, roulette and craps, slot machines, poker rooms and more. Some even offer luxurious accommodations, restaurants and other amenities.

Generally, most games at casinos have mathematically determined odds that give the house an advantage over the players. This advantage is called the house edge or expected value. Casinos make their profits by taking a commission, called the rake, from the games or by charging a flat fee for each game. In the case of card and table games, this is a percentage of the total wagers placed. Casinos have taken many steps to ensure that their patrons are not cheating. Security personnel watch casino games with a close eye, and can quickly spot blatant actions such as palming cards or marking dice. Table managers and pit bosses also keep an eye on the betting patterns of players to look for any unusual activities.

While casinos are popular with a wide range of people, they tend to attract older adults who have more free time and disposable income. In 2005, the average American casino gambler was a forty-six-year-old female from a household with an above-average income.
