A casino, in the broad sense of the word, is a building that houses certain types of gambling. Slot machines, black jack, roulette, craps, and keno are all examples of casino games. A casino may also have entertainment on stage. The term is a contraction of the French words for “place where gambling is carried out.” The first modern casinos opened in the second half of the 19th century, and they were often built near water. Today, there are many casinos worldwide. Some states have laws that regulate the operations of casinos. Others have no such regulations, while some have banned the establishment of a new casino altogether.
Something about casinos seems to encourage people to cheat or steal in order to win money. That is why casinos spend a large amount of time, effort and money on security.
Despite their emphasis on gambling, casinos are actually businesses that rely on patrons to make money. The house always has a mathematical advantage over the players, and this advantage is known as the house edge. The casino earns its profits by taking a small percentage of every bet, or a commission called the rake.
While the idea of a place to find a variety of ways to gamble probably predates recorded history, the idea of a casino as an institution didn’t develop until the 16th century, when a gambling craze swept Europe. Italian aristocrats would hold private parties at places called ridotti, where they would be free to gamble as much as they wanted without fear of legal sanction.
