A casino is an establishment for gambling. It features games of chance and skill such as blackjack, roulette, craps, baccarat, poker, and slot machines. Many casinos also have other entertainment activities such as restaurants, bars, and live music. Casinos are most often built near or combined with hotels, resorts, and other vacation attractions.
In some cases, casino patrons may be tempted to cheat and steal, in collusion or independently; therefore, most casinos have security measures in place to deter this. The most basic measure is security cameras throughout the facility. More sophisticated casinos use catwalks extending above the gaming floor, which allow surveillance personnel to view game play directly.
Casinos can be very large, with thousands of slots and hundreds of tables. They are usually decorated with bright and sometimes gaudy colors to stimulate the senses of players and lure them into making bets. Red is a particularly popular color used in casino decoration, since it has been shown to be a distracting color that makes people lose track of time.
Some casinos feature traditional Far Eastern games such as sic bo, fan-tan, and pai gow. In addition, some have specialty games that are popular in regions such as two-up (Australia), banca francesa (Portugal), boule (France), and kalooki (UK). Casinos have evolved into casino resorts where guests can enjoy well-rounded experiences that transcend gambling. As such, they have become a major source of revenue for a growing number of countries.
