What Is a Casino?

A Casino is a gambling establishment where people can gamble on various games of chance. Casinos often add a variety of luxuries to attract customers, including restaurants, free drinks and stage shows. Casinos are generally regulated by state laws and must be licensed to operate. Some states require that the legal age to gamble in a casino be 21. The legal age to play casino games online varies by country.

Gambling probably predates recorded history, with primitive protodice and carved six-sided dice appearing in archaeological sites. However, the modern concept of a casino as a place where patrons can find many different ways to gamble under one roof didn’t emerge until a gambling craze swept Europe in the 16th century. This led to the development of aristocratic parties called ridotti, where gamblers could wager on anything from a horse race to the outcome of a battle.

Today’s casinos have gone far beyond the ridotti of old, with video cameras and computers monitoring all sorts of activities within their walls. Betting chips with built-in microcircuitry enable casinos to oversee the exact amounts wagered minute by minute, and roulette wheels are monitored electronically to discover quickly any statistical deviation from expected results.

Some casinos offer free goods and services to “good” players, a practice known as comping. These can include free hotel rooms, dinners and tickets to shows, and may even extend to limo service and airline tickets for the biggest spenders. If you’re a high-volume player it pays to ask a casino employee about which machines are hot, though keep in mind that most employees have strict confidentiality policies and may not be willing to share information with non-gamblers without a tip.
