The modern casino looks like an indoor amusement park for adults, but the vast majority of the entertainment (and profits for the owners) comes from games of chance. Those include slots, blackjack, craps, roulette and the like. While musical shows, lighted fountains and lavish hotels help lure the crowds, casinos would not exist without games of chance.
Although some people think casinos are a shady place to spend money, many casinos try to present a classy image. Some even offer spas, restaurants and luxury hotels. Some of them have been designed by famous architects, including Charles Garnier, who designed the Paris opera house.
Some casinos make a significant part of their profits from “high rollers,” who gamble with much higher stakes than the average person. Such high-stakes players may gamble in special rooms away from the main floor. They may also receive comps for free hotel rooms, dinners, tickets to shows and, in some cases, limo service and airline tickets.
The casinos also try to lure in patrons with flashy advertising and brightly colored floors and walls, which have been proven to stimulate the gambling impulse. Red, for example, is a popular color because it is believed to cause people to lose track of time. Some casinos even have no clocks on the walls to further encourage a sense of time loss.
Some casinos are prone to cheating by both patrons and employees. Casinos employ a variety of techniques to prevent this, from using video cameras to monitor games, to the use of chips with microcircuitry that allow casinos to oversee the exact amounts wagered minute by minute, and the electronic monitoring of roulette wheels to quickly discover any statistical deviations from their expected results.
