What is a Casino?

The word casino has multiple meanings, but its primary connotation is a building that houses gambling activities. Many casinos add luxuries like restaurants, free drinks and stage shows to lure patrons in, but even places without these amenities could technically be called casinos.

Many casinos have loyalty programs in which patrons are rewarded for their play. These usually involve a player card that can be swiped before a game to track play and tally up points that can be exchanged for discounts on meals, drinks or free slot plays. These programs also develop patron databases that can be used for marketing purposes.

Most casinos make money by absorbing the statistical advantage built into every game offered, sometimes as low as two percent of each bet. This edge may seem small, but over millions of bets it can yield substantial profits that enable casinos to build extravagant hotels, spectacular fountains, towers and replicas of famous landmarks.

To maximize profits, casinos target big spenders and offer them special inducements such as free hotel rooms, dinners, show tickets and limo service. High rollers often gamble in rooms separated from the main casino floor, where the stakes can be as high as tens of thousands of dollars. Security personnel watch players closely to spot unusual behavior that may signal cheating or stealing, either in collusion with other patrons or independently. The large amount of currency handled within casinos makes them susceptible to theft by both employees and patrons, but most have security measures in place to reduce these risks.
