A public room or building where playing gambling games (such as roulette, baccarat, blackjack, poker, and slot machines) is the principal activity. Casinos are also used to host events and entertainment, such as concerts, shows, and other activities that appeal to a wide audience. Casinos often have restaurants and bars as well, so patrons can eat and drink while they play.
In modern casinos, security starts with a network of cameras that provide an “eye-in-the-sky” view of the entire floor. These are controlled from a separate room filled with banks of monitors that can be adjusted to focus on suspicious patrons. Another technological advance is a system called “chip tracking,” whereby betting chips have built-in microcircuitry that allows the casino to track the amount wagered minute by minute and detect any statistical deviations from expected outcomes.
There are a variety of other steps casinos take to keep gamblers happy and coming back, including free food and drinks, luxury suites, clubs, pools, concerts, and golf courses. But the best way to keep people gambling is to make the place feel like a refuge, according to design experts. That’s why many casinos use red and gold tones, have soft lighting, and make the money they give away look more like chips than actual cash, so gamblers won’t think twice about losing it all.
