A casino is a place where people can play games of chance for money. It is not a glamorous affair, but it does generate billions of dollars in profits each year. While musical shows, lighted fountains and lavish hotels help lure customers in, casinos would not exist without games of chance. Slot machines, blackjack, roulette and craps are the main attractions that provide patrons with a reason to spend their cash in a casino.

For the most part, gambling was illegal throughout most of America’s history. Organized crime figures had plenty of cash from their drug dealing and extortion rackets, so they were eager to invest it in casinos, which were seen as lucrative money makers. But legitimate businessmen were reluctant to become involved in a business that had the taint of vice. It was not until Nevada legalized casinos in 1931 that the industry began to expand.

Today’s casinos are a little more choosy about who they let in the door. They focus on high rollers, who bet much more than the average gambler and who are likely to spend a great deal of money. In return, the casino offers them extravagant inducements such as free spectacular entertainment and luxury suites.

Modern technology also keeps casinos safe from cheating and theft by both patrons and employees. For example, electronic systems in table games monitor betting chips with built-in microcircuitry and alert security personnel when statistical deviations occur. Video cameras are another important tool used by security departments. In addition, windows and chimes are rare in most casinos so that gamblers can lose track of time.
