A casino is a building or room in which gambling games are played. Most casinos offer a variety of gaming options, including blackjack, roulette, poker, and slot machines. Some even have sports betting, where players can place wagers on American football, boxing, and other events. Many of these casinos are known for their luxurious design, which makes them popular tourist attractions. Las Vegas has the largest concentration of casinos in the world, while Atlantic City and Chicago are other major gambling centers.

A small number of casinos specialize in particular games, such as baccarat (in its popular variant, chemin de fer), bingo, or dice. Others have an emphasis on table games, such as baccarat, blackjack, and poker. In some cases, these tables are surrounded by restaurants and bars. Casinos may also have a large area devoted to electronic gaming, such as video poker and keno.

Given the large amounts of money handled in a casino, security is a high priority. Both patrons and staff may be tempted to cheat or steal, in collusion or independently; for this reason, most casinos employ security cameras and monitors. Some casinos use technology to improve the fairness of their games, such as “chip tracking” that allows a computer to oversee the amount of money wagered minute by minute, and to detect any deviation from expected results; or “chase” systems that electronically track each individual player’s bets to prevent collusion.

In addition to standard games of chance, most casinos feature several traditional Far Eastern table games, such as sic bo (which was introduced to American and European casinos in the 1990s), fan-tan and pai gow. Many of these casinos also offer a variety of Asian poker games, such as baccarat and trente et quarante.
