What Is a Casino?


A casino is a facility for certain types of gambling. Casinos are often built near or combined with hotels, resorts, restaurants, retail shopping, cruise ships, and other tourist attractions. In addition to gambling, a casino may also offer other entertainment options such as shows or concerts.

The casino business is regulated in many jurisdictions, and the legality of casinos depends on factors such as location, type of games offered, and the number and quality of tables. Several states have established gaming commissions to oversee the operation of casinos. Some casinos are run by Indian tribes, and some are owned by public corporations or private individuals.

Most modern casinos are designed with a theme, and the architecture of the building is usually related to that theme. For example, the Golden Nugget in Las Vegas is decorated with gold and mirrors, while Caesars Palace uses a Romanesque Revival style. The decor of a casino is intended to stimulate the gambler’s senses. The lighting is typically bright, and the walls and floor are frequently covered in colors that have a stimulating effect. Red, in particular, is a popular color because it is believed to make people lose track of time. In addition, the absence of clocks on casino floors is intended to create an atmosphere of perpetual night.

Table games are a staple of the casino industry and are found in most large casinos. Some of these games, such as craps and roulette, are operated by live croupiers, while others are machine-based. A casino’s table game revenues account for a significant percentage of its overall gross revenue.

Some casinos specialize in specific games, such as blackjack or poker. In the United States, poker tournaments and other events are held regularly at major casinos. The World Series of Poker is one such event, and it is the most popular live poker event in the world. In addition, some casinos host speciality table games, such as Casino War and Keno.

The house edge is the mathematical advantage that a casino has over its patrons in individual casino games. It is typically expressed as a percentage, and it gives the casino a consistent profit over the long term, assuming that the house does not change its rules or cheat. In some cases, skillful players can eliminate the inherent long-term advantage of the casino by making optimum decisions at the table. These players are known as advantage players.

During the 1990s, technology greatly improved the security and supervision of casino games. Electronic systems monitor the amount of money wagered on each bet, minute by minute; and automated betting wheels ensure that the results of each spin correspond closely to the expected values. Security personnel are also trained to spot any suspicious activity or behavior. Casinos also use surveillance cameras to monitor patrons’ actions. Some casinos have catwalks in the ceiling above the casino floor, where security personnel can look directly down through one-way glass at the tables and slot machines.
