A casino is a gambling establishment, offering various games of chance to its customers. These games can include a range of slot machines, table games like blackjack and roulette, and card games such as poker. Casinos also offer a variety of entertainment options, such as live music and sports events. Some casinos are built as resorts and have other features such as restaurants, luxury accommodations, and shopping areas.

Most games have mathematically determined odds that ensure the house has an advantage over players, known as the house edge. This advantage is built into the game’s rules, and can be expressed in terms of expected value (which is uniformly negative from the player’s perspective). Some games have an element of skill, such as craps, baccarat, and blackjack, while others are purely random, such as sic bo and keno.

In addition to traditional casino games, some casinos offer Far Eastern games such as sic bo (which spread to several European and American casinos in the 1990s), fan-tan, and pai gow. Some casinos also have electronic versions of these games, which are monitored for statistical deviations from their expected results.

Many famous casinos are located in cities that are known for gambling, such as Las Vegas and Atlantic City. During the 1980s, a number of states amended their laws to permit casino gambling, and a few have casinos on Indian reservations, which are exempt from state antigambling statutes. Casinos can also be found in many cities around the world, as well as cruise ships and some airports.
