A place that allows people to gamble on games of chance and, in some cases, skill. Casinos usually feature slot machines, blackjack, poker, roulette, and craps, among other games. They make their money by taking a commission from each bet, often called the rake.

Casinos are often located in large cities or tourist destinations, such as Monte Carlo, Atlantic City, and Las Vegas. In some countries, casinos are licensed and regulated by the government. In others, they operate in a legal gray area. Casinos often provide free drinks, hotel rooms, and other amenities to attract customers. Many offer live entertainment, including concerts and shows.

While most casino patrons are honest, some may try to cheat or steal, either in collusion with other patrons or independently. To counter this, most casinos have a variety of security measures. They typically employ a combination of physical security personnel and specialized surveillance departments to monitor the activities of players and staff.

In recent years, some states have expanded the number of casinos. For example, Arkansas has built a high-rise casino in West Memphis that towers over the city skyline. In addition, several states have legalized sports betting in casinos or online. Some critics say this expansion harms low-income residents and hurts property values in nearby neighborhoods. The industry is also attracting more people with gambling addictions. To combat this, some advocates call for a wholesale reform of the current system that operates more like a casino than an efficient machine for distributing capital.
