What is a Casino?

A casino is a place where people play games of chance for money or other rewards. The games often have elements of skill, but the house always has an advantage over the players. The advantage is called the house edge, and it’s what casinos rely on to make profits.

Modern casinos offer a variety of games to attract and retain customers, including blackjack, poker, video poker, craps, roulette and slots. Some are enormous resorts, while others are small card rooms. Regardless of size, they all depend on gambling to generate billions of dollars in revenue each year for the companies, investors, hotel owners and state and local governments that run them.

Casinos rely on an array of tricks to lure and keep patrons, from the design of their gambling spaces to their sound and light systems. The sounds of slot machines and the clatter of dice hitting tables are designed to create an exciting and mysterious atmosphere, and more than 15,000 miles of neon tubing are used to illuminate the casinos on the Las Vegas Strip.

Casinos are also sophisticated in their use of technology to monitor their games and protect their assets. Chips with built-in microcircuitry allow casinos to monitor the exact amount of money wagered minute by minute, and roulette wheels are electronically monitored to discover quickly any statistical deviation from their expected results. Moreover, casinos have a highly specialized security department that operates closed circuit television systems, or “eyes-in-the-sky,” that enable them to monitor all areas of their facilities at once.
