A casino is a place where people can play a variety of games of chance for money. Some casinos also offer other types of entertainment, such as stage shows and free drinks. Casinos can be found in a wide range of locations, from seaside resorts to downtown cities. They may also be combined with hotels, restaurants, retail shops, and other tourist attractions.

Gambling probably predates written history, with primitive protodice (cut knuckle bones) and carved six-sided dice being discovered in archaeological digs. The modern casino as a public gambling house developed in the 16th century, when a gambling craze swept Europe. Italian aristocrats would gather in private clubs called ridotti to gamble and socialize, even though the activities were technically illegal [source: Schwartz].

The main economic component of casinos is gambling, which produces more revenue than any other activity except for restaurants and bars. However, some critics point out that the profits are skewed by addiction and the cost of treating problem gamblers, which eats into any profits. In addition, local workers spend their wages in casinos, which decreases the amount of money in the local economy.

A casino’s security starts on the floor, where employees keep their eyes on players and the games to ensure that everything is going as it should. Table managers and pit bosses have a broader view of the action, watching for blatant cheating like palming or marking cards. In addition, slot machine players are tracked by a “higher-up” person to make sure that their play is consistent with the number of credits they deposit and to see if any irregularities occur. In addition, a casino will often reward loyal patrons with comps, such as free hotel rooms, food and beverages, show tickets or reduced-fare transportation.
