What Is a Casino?

A casino is a gambling establishment where various games of chance are played. Most casinos also offer food and drinks, as well as other entertainment. Some casinos are large and impressive, while others are small and intimate. They may be located in tourist destinations, or they may be built near resorts and other attractions. In addition to slot machines and tables, many casinos feature other games like video poker and keno. Some are known for promoting a particular type of gaming, such as baccarat or blackjack.

The word casino is derived from the Latin cazino, meaning “little house.” In modern usage, it refers to any place where gambling is legal. However, the term is more often used to describe a specific building or complex of rooms dedicated to gambling and other entertainment. Some of the largest casinos in the world are located in Las Vegas and Macau, China. Others are in Atlantic City and Chicago. Many states have legalized casino gambling, and more are considering it.

Gambling has a long and colorful history. In ancient times, people betted their possessions, including slaves and livestock, on events of uncertain outcomes. Later, the Romans and the Greeks developed games of chance, such as dice and alethia. In the 19th century, American railroads opened a number of new gambling houses, and the popularity of these facilities grew rapidly. By the 1930s, most major cities had at least one casino, and the number increased in the 1950s as more and more states legalized gambling.

Modern casinos are heavily guarded against cheating and stealing, both by staff and patrons. Security measures include cameras, which watch every table, window and doorway. Electronic systems monitor betting chips minute by minute, and can alert the staff to any significant deviation from expected behavior. Casinos also use specialized software to detect irregularities in the spin of roulette wheels, and to spot sloppy dealing.

Despite the emphasis on security, casino gambling is still a dangerous business. In addition to the potential for theft and fraud, there is a constant threat of violence from mobster gangs. In Nevada, where casino gambling first became popular, organized crime figures controlled the majority of the casino owners and were able to manipulate games of chance to their advantage. In some cases, they took sole or partial ownership of casinos and influenced the outcome of games with the threat of violence to casino personnel.

In addition to cameras, security personnel patrol the casino floor on foot and by car, looking for sloppy dealers or suspicious patrons. Security officers also keep close tabs on card and dice players, watching for blatant cheating or the switching of cards or dice. In more sophisticated casinos, an elaborate system of cameras offers a “eye-in-the-sky” view of the entire casino, and can be focused on a particular table or suspect by security workers in a room filled with banks of security monitors. These cameras can also record all transactions and payouts, allowing security personnel to check them after a game is over.
