A casino (sometimes spelled caino or kasino, from the Spanish word for “gambling house”) is an establishment that offers certain types of gambling. Casinos are often combined with hotels, resorts, restaurants, retail shopping, cruise ships, and other tourist attractions. In addition to offering traditional gambling, some casinos host live entertainment and sports events.

Though casinos may feature musical shows, lighted fountains, lavish hotels and elaborate themes, they would not exist without the games of chance that draw in the crowds and generate billions in profits each year. Slot machines, blackjack, roulette, baccarat and craps are the mainstays of American casinos, while Asian casinos offer sic bo, fan-tan and pai-gow.

While some form of gambling almost certainly predates recorded history, the modern casino as a place for people to find a variety of ways to gamble under one roof did not develop until the 16th century during a gambling craze in Europe. Italian aristocrats would gather in private places called ridotti to play dice and other games, often avoiding legal authorities as they did so.

Although the games of chance are central to the casino experience, other factors contribute to its popularity and profitability, including the appeal of the glitz and glamour that it exudes and the excitement of trying to win big. Something about the nature of casino gaming also encourages cheating and stealing, which is why casinos spend so much time and money on security. In addition to the use of high-tech surveillance systems, casino security teams rely on patterns and routines: The way dealers shuffle and deal cards, where players normally sit at the table, how they typically react and motion, are all closely monitored.
