A casino is a place that hosts a variety of gambling games and provides an atmosphere that is designed around noise, light, and excitement. Casinos can range in size from a small establishment to the massive Las Vegas strip casinos. While entertainment shows, restaurants and shopping centers can help draw in the crowds, the vast majority of the profits are derived from gambling. Slot machines, blackjack, roulette and other popular casino games are responsible for the billions of dollars in profits raked in by casinos each year.

To maintain profitability, casinos must balance the number of customers with the amount of money wagered by each customer. This is why it is common for a casino to offer big bettors extravagant inducements in the form of free spectacular entertainment, transportation and elegant living quarters. To attract smaller bettors, casinos often lower the house edge on their tables and machines to less than a percentage of the total amount bet.

Many casinos employ elaborate security measures to prevent cheating, tampering and other forms of fraud. For example, chips with built-in microcircuitry allow a casino to monitor the amounts placed minute by minute; video cameras are wired throughout a casino to provide an “eye-in-the-sky” view of every table and window; and electronic systems are monitored regularly to detect any statistical deviation from expected results.
