What is a Casino?

A casino is a facility for certain types of gambling. Casinos are often built near or combined with hotels, restaurants, retail shopping, cruise ships and other tourist attractions. In some countries, casinos are operated by government-owned enterprises. A casino is also known as a gaming house, or gambling house. In American usage, the term is most often applied to casinos in Las Vegas and Atlantic City.

The casino industry is a major source of revenue in many countries. The largest gambling market in the world is the United States, followed by Japan and Macau. In terms of space, the biggest land-based casino in the world is Winstar World Casino and Resort in Oklahoma (home of Woody Guthrie and chicken fried steak).

Most casinos offer table games like blackjack and roulette, but some also feature a wide variety of video poker, sports betting, and other games. In addition, some casinos are known for their lavish suites and amenities. These include a private club, VIP rooms, and a selection of the latest slot machines.

Casinos use technology to track wagers and to prevent cheating. For example, in some American casinos the use of electronic chips with built-in microcircuitry allows the casino to oversee betting minute by minute and warn players of any suspicious activity; roulette wheels are monitored electronically to ensure that they are rotating at exactly the right speed. Casinos also employ a number of mathematicians and computer programmers to analyze game outcomes and determine the house edge, or expected value.
