A casino is a facility that offers the opportunity to gamble. These facilities provide entertainment to a wide variety of patrons, and their profits come primarily from the gambling business itself. While casinos feature many other attractions, such as lighted fountains, musical shows, and lavish hotels, their existence would not be possible without the billions of dollars in gambling revenues they generate each year. Gambling games that are legal to play in casinos include number games such as lotteries and instant lottery games, poker and other card games, casino table games, and slot machines.
Casinos are heavily policed for security, and modern technology plays a significant role in their operations. Cameras in the ceiling track every table, window, and doorway and can be focused to zoom in on suspicious patrons by security workers stationed in a room filled with banks of monitors. Roulette wheels are electronically monitored to discover any statistical deviations from their expected results. Casinos also use chip tracking systems to record every betting transaction, and some have wholly automated games, like blackjack and roulette, that can be operated by push buttons.
Casinos also focus on “high roller” clients, who are those gamblers who place bets of tens of thousands of dollars or more. They are often given free luxury suites, spa treatments and other amenities to entice them to spend money. They are also given special rooms to gamble in, away from the general gambling floor, where their bets can be made with a single chip.
