What Is a Casino?


A casino is a modern establishment where gambling activities take place. While musical shows, lighted fountains and shopping centers may draw in customers, the majority of the profits come from games of chance like blackjack, roulette, craps and slot machines.

Modern casinos are a blend of luxury and strict discipline. They employ a staff of security personnel to ensure that patrons do not cheat or steal, either in collusion with others or alone. Elaborate surveillance systems provide a high-tech “eye in the sky” to watch tables and windows as well as every doorway, entrance or exit. In addition, the security department keeps track of all the games and players.

Although the exact origin of gambling is unknown, it is believed that some form has existed throughout history in most societies. Ancient Mesopotamia, the Greeks, Romans and Elizabethan England all had games of chance. Modern casino gaming became popular in the United States after World War II, when many states passed laws allowing them.

The majority of today’s casinos are located in Las Vegas, Nevada, but there are many other casinos around the world. Many of these casinos offer online gambling for US players.

A few casinos are also devoted to card games such as poker. These are standalone establishments or small rooms separated away from other casinos where poker and similar games can be played in a small group. Unlike the traditional casinos, these facilities do not usually employ house dealers or pay out winnings in cash.
