What is a Casino?

Casino is a popular establishment where a variety of gambling-related games can be played. These include slot machines, roulette, blackjack, poker, craps and keno. Casinos also feature entertainment, restaurants, hotels and nongambling activities. Historically, casinos were largely found in Nevada and other states where gambling was legalized, but the number of casinos rapidly increased as other areas legalized gaming as well.

In a casino, there are no clocks in the buildings or on the casino floors because they want gamblers to lose track of time and continue betting. The lights are bright and sometimes gaudy, and music and noise are designed to create excitement and encourage people to gamble. Casinos often provide free drinks, and alcoholic beverages are served at tables by waiters who circulate around the floor.

Despite the flashy decor and free cocktails, casinos are businesses built on a foundation of mathematics, engineered to slowly bleed patrons of their money. For years, mathematicians and other technically inclined people have tried to turn the tables on casinos by using their knowledge of probability and game theory to exploit weaknesses in a system that is designed to bleed players of their money.

Nevertheless, something about the environment of a casino seems to inspire people to cheat or steal. In fact, many people have been arrested for stealing chips from the table or even attacking other players. Fortunately, casinos spend enormous amounts of time and money on security. They also employ a wide range of technological tools to prevent theft and cheating. These technologies range from sophisticated chip tracking systems that allow casinos to monitor player bets minute-by-minute to automated and closed versions of games such as roulette, where a computer controls the action.
