A casino is a gambling establishment. Generally, casinos feature games of chance and skill. Gaming machines (slots) are the most common, but there are also table games such as blackjack and baccarat. These are usually conducted by croupiers and require the participation of the player. There are also random number games such as roulette and keno that involve the selection of numbers.
Gambling has been around for millennia. The earliest evidence of dice dates back to 2300 BC, while card games first appeared in Europe in the 1400s. Despite the fact that many casino visitors are not looking for a high-stakes game, gambling has become one of the world’s most popular pastimes.
The most prestigious and renowned casino in the world is the Casino de Monte-Carlo, which was opened in 1863. This belle epoque building is located on the shores of the Mediterranean Sea, in Monaco.
Modern casinos are usually divided into specialized departments for security and surveillance. These departments usually employ a physical security force that patrols the casino and reacts to requests for assistance or reports of suspicious or definite criminal activity. Surveillance is carried out by a separate department that monitors closed circuit television. Some casinos also have catwalks in the ceiling where surveillance personnel can look directly down, through one way glass, on the tables and slot machines. This system is called a “eye in the sky”. In addition, some casinos have specialized computer systems that supervise the games themselves, such as “chip tracking,” where betting chips are electronically monitored to determine exactly how much money is wagered minute by minute; and roulette wheels are regularly electronically monitored for statistical deviations from expected results.
