What Is a Casino?

A casino is an establishment for certain types of gambling. In some countries, casinos are regulated by law. They may be located near or combined with hotels, restaurants, retail shops or cruise ships. Some casinos specialize in a particular type of game, such as poker or horse racing. Others are known for their entertainment offerings, such as shows or sports events.

Casinos make money by taking a percentage of the total bets made, often called vigorish or rake. This amount varies by game, but is typically less than two percent. Casinos also earn money by giving complimentary items to players, known as comps. They may also charge a flat fee for the use of a table, such as the cost of dealing chips.

Many casinos are situated in cities with large populations, where gambling is legal. In some countries, such as the United States, state governments regulate the operation of casinos. However, many casinos are located on American Indian reservations, which are exempt from most state laws regulating gaming.

In the twentieth century, casinos became increasingly upscale and began targeting high rollers. These gamblers spend more than average, and they are rewarded with free entertainment, transportation and luxurious living quarters. In addition to focusing on high rollers, casinos are investing in technological advancements that can detect cheating. For example, roulette wheels are now routinely monitored electronically to discover any statistical deviations from their expected results.

Due to the high amounts of money handled within a casino, both patrons and employees are occasionally tempted to steal or cheat. This may occur in collusion with other patrons or as independent acts. To prevent this, most casinos use security measures including video cameras and random auditing.
