Casino is a gambling establishment where a variety of games of chance can be played. It is usually a large, luxurious place that adds many extras to the usual gambler’s games such as free drinks, stage shows and dramatic scenery. Although gambling in some form predates recorded history, the modern casino as we know it did not develop until the latter half of the 20th century. Prior to that, casinos were often private clubs for rich members and were known as ridotti.

Most casino games are based on luck, but some involve skill. The odds of a particular game are mathematically determined, and the house always has a slight advantage over players. Casinos are able to make huge profits because of this.

Something about gambling seems to encourage people to cheat or steal, and casinos spend a lot of time and money on security. The typical casino has a physical security force and a specialized surveillance department. Casinos also employ a number of psychological tactics to discourage problem gambling. For example, they use bright and sometimes gaudy floor and wall coverings that are stimulating and distracting to the eye. They also avoid clocks on the walls because they can cause players to lose track of time.

Successful casinos bring in billions of dollars each year for the companies, investors and Native American tribes that own and operate them. They also generate a significant amount of revenue for state and local governments through taxes and fees.
