Casinos are public places where a variety of games of chance are played. They usually feature loud, brightly lit gaming tables and a partylike atmosphere. In modern casinos patrons can choose from a variety of gambling activities, including poker, blackjack and slot machines. Casinos are typically owned by private companies, corporations or Native American tribes. They make billions of dollars in profits each year. They pay millions of dollars in taxes to state and local governments.
While musical shows, lighted fountains, restaurants and lavish hotels help attract customers to casinos, they would not exist without games of chance. Slot machines, roulette, craps, baccarat and blackjack provide the billions of dollars in profits that casinos rake in each year.
Almost every game of chance has mathematical odds that ensure the house has an advantage over players. This advantage is called the house edge. In some games, such as poker, the house takes a commission from each bet. This is known as the rake. Casinos also give out free goods and services to gamblers, called comps. For example, if you play at the same table or slot machine for long periods of time, you may be entitled to free food, drinks and hotel rooms.
Something about gambling seems to encourage people to cheat, steal and scam their way into a jackpot. For this reason casinos spend a great deal of money on security. High-tech surveillance systems have an “eye in the sky” that allows security workers to watch every table, change window and doorway in a casino at once. They can also zoom in on suspicious patrons.
