A casino is a public place where a variety of games of chance can be played. It can include gambling activities as well as other pleasurable activities like restaurants, live entertainment and shopping centers. Although casinos may be adorned with all sorts of extravagant extras such as musical shows, lighted fountains and expensive hotels, they would not exist without their primary focus of gambling. Slot machines, blackjack, roulette, craps, baccarat and poker generate the billions in profits that casinos bring in every year.
While the excitement and suspense of casino gaming keep people coming back, the truth is that it’s mostly a matter of luck. The mathematical odds of most games provide the house with an advantage, or a negative expected value, and the houses take a percentage of all wagers made by players on a game, known as the rake.
In addition to high-tech surveillance systems that give casino employees a virtual eye-in-the-sky, security also starts on the gaming floor. Dealers keep an eye out for blatant cheating (palming, marking or switching cards or dice) and can easily spot suspicious betting patterns on the tables. And pit bosses and table managers can hone in on specific patrons with the help of cameras pointed at each table, doorway and window.
Besides security, casinos also try to lure people with free food and drink and rooms at their adjoining hotels. But while these luxuries are fun, they can lead to addiction. That’s why casinos must carefully balance the fun with the financial risks and keep a close eye on the games that are most popular with patrons. They must be able to predict the average winnings and losings for each game. To do this, they hire mathematicians and computer programmers who specialize in gaming analysis.
