Whether you like to spin the roulette wheel, hit the tables for a game of blackjack, throw dice at a craps table, or put on your best poker face, a casino is the place to scratch that gambling itch. While casinos are famous for their opulent luxury, they have always been places where people could find a variety of ways to gamble under one roof.

While gambling has likely existed since recorded history, the modern casino as we know it began in the 16th century during a gambling craze that swept Europe. It was in this period that European nobles would hold parties at their houses, called ridotti, where they gathered to play a variety of games of chance including dice and cards.

Today, a casino is a highly structured environment that allows patrons to wager on various events with the house taking a small percentage of all money wagered. Casino security begins on the gaming floor, where dealers are trained to spot blatant cheating such as palming or marking cards, and pit bosses oversee the activities of each game with a more broader view. Players are required to keep their chips in sight at all times, and casino employees monitor betting patterns for signs of cheating or collusion.

Casinos also offer free food and drink to their patrons, which may help keep them on the premises longer and increase their likelihood of winning. In the United States, casinos are largely legal and provide a significant source of income for their owners. They also attract a wide range of tourists who spend money on gambling, restaurants and other entertainment.
