A casino is a building or room where people can gamble on games of chance. These games include poker, blackjack, roulette, craps, baccarat, and video slots. Casinos also offer food and drinks. They often have stage shows and other entertainment. Casinos make their money by taking a percentage of the bets placed by patrons.
Many casinos use security measures to prevent cheating and other forms of unauthorized activity. They have special personnel to watch over table games, and pit bosses and managers keep a close eye on the casino floor. Some casinos even have “chip tracking” systems that monitor the amount of money wagered minute by minute and alert supervisors to any statistical deviation. Other casinos have catwalks that allow surveillance personnel to look down, through one-way glass, at the tables and slot machines.
Most casinos give out free goods and services to big spenders, or “comps.” The comps depend on how much a person spends at the casino. Some are free meals, drinks or tickets to shows, while others are hotel rooms, limo service and airline tickets. The comps are designed to encourage gambling and keep gamblers coming back. Casinos also spend a large amount of money on security, because something about gambling seems to attract criminals.
