What is a Casino?

A casino is a gambling establishment that offers a variety of games of chance and some that involve skill. Some of the most popular games at a casino include poker, craps, roulette, and blackjack. The house, or banker, has a mathematically determined advantage in all games played at the casino, and this is known as the house edge. A percentage of funds wagered is taken by the house as a commission, and this is called the rake. Casinos also give out complimentary items to gamblers, which are known as comps.

The casino industry has become very sophisticated in the use of technology to monitor and control the games. In addition to security cameras, casinos now routinely use chips with built-in microcircuitry to enable the casino to oversee exactly how much is wagered on each game minute by minute and be alerted to any anomalies; and roulette wheels are electronically monitored to discover any statistical deviations from expected results.

Many casinos cater to high rollers who gamble in excess of tens of thousands of dollars at a time. They offer them special rooms, often separate from the main gaming floor, and lavish personal attention. Some even have a dedicated staff to handle their needs. Comps may be free food, drinks, or rooms; discounted travel packages; and show tickets. These perks are designed to encourage gamblers to spend more money, and to reward those who do. This strategy is the basis of a major portion of the income of many casinos, and it is one of the primary reasons that Las Vegas is the world’s most famous gambling destination.
