What Is a Casino?



A casino is an entertainment venue that offers games of chance and skill. These gambling establishments are found in massive resorts and small card rooms and on ships, barges, racetracks, in some states where it is legal to allow slot-type games, and even in airports and hotel rooms (in the form of racinos).

Casinos attract gamblers with dazzling displays of lights, sounds and action. They offer alcoholic drinks and food, and feature music and shows. They also give away free rooms, meals and show tickets to certain gamblers. These rewards are called comps. Casinos also track gamblers’ play using computer chips, which are swiped by patrons before they place a bet. The information is recorded in a database, which can be used to offer gamblers more targeted marketing.

Most casinos make their money by taking a percentage of each bet, a practice known as vigorish or the rake. The house advantage can be low, less than two percent, but over millions of bets, it adds up. In addition, casinos earn money by charging players for the use of their facilities and equipment. This revenue is a significant portion of a casino’s profits, and it helps offset the cost of such amenities as hotel rooms, fountains and giant pyramids or tower replicas.

Something about casinos seems to encourage cheating, stealing and other forms of deception. As a result, casinos devote a lot of time and effort to security. They have cameras everywhere, and monitor every table, window and doorway. In addition, they have high-tech systems that enable them to track each bet minute by minute and instantly detect any anomalies.
