A casino is a place for gambling and other entertainment. It may be accompanied by hotels, restaurants, retail shops and other tourist attractions. A casino also may have an arcade, theater or show to provide extra entertainment for its patrons. The games played at casinos are based on random chance. The profits made by the casinos from the games are small, but over the millions of bets they receive, they earn a substantial income. This is the reason that many casinos have fountains, towers or pyramids and recreate famous landmarks.
Something about the casino environment encourages people to cheat or steal, either in collusion with each other or independent of each other. This is why casinos spend a great deal of time, effort and money on security. Security starts on the casino floor, where employees keep an eye out for blatant cheating such as palming or marking cards, or for other activities that would detract from the gaming experience. Table managers and pit bosses have a broader view of the table games, and watch for betting patterns that could signal cheating.
Although gambling almost certainly predates written history, it wasn’t until the 16th century that the idea of a casino emerged, as a place where people would find all the different ways to gamble under one roof. These early casinos, called ridotti, were popular in Italy, where legal gambling was permitted. They were heavily supported by organized crime, which had a lot of cash from drug dealing and extortion rackets.
