A casino is a place where people gamble on games of chance. It is a very lucrative business, raking in billions of dollars every year. Although many casinos have lavish hotels, fountains and towers resembling famous landmarks, the vast majority of revenue is generated by gambling on games like slot machines, black jack, roulette and craps.
Casinos are designed to keep patrons entertained, and that means a lot of attention to the details of design and decor. Lush carpets and richly tiled hallways compliment carefully designed lighting, which is often a little dim to help patrons forget about the passing of time. Casinos also display a large prize (typically a sports car or something similar) to lure gamblers in.
Because large amounts of money are handled inside a casino, security is very important. Some gamblers will try to cheat or steal, either in collusion with others or on their own. That is why most casinos spend a great deal of time and money on elaborate security systems. Cameras are placed throughout the facility to keep an eye on everything, and specialized cameras are used in high-risk areas like the gambling floor and the doorways.
In the past, casinos were open to anyone who wanted to gamble, but in the modern age they are much choosier about who they allow to gamble there. They especially look for high rollers, or people who bet a large amount of money. These people are given a great deal of attention by the casino, and are usually allowed to gamble in special rooms that are isolated from the main floor. They are also offered comps, which are free goods or services that the casino gives to its best customers.
