A casino is a gambling establishment that offers a variety of games of chance and some skill. Its customers gamble by playing table games such as blackjack, roulette, and poker and by placing bets on machines such as slot machines or video poker. Most casinos also offer sports betting and various other types of lottery-style games. Casinos often have extensive security measures and use technology to monitor and audit their operations. For example, in a process called “chip tracking,” betting chips with built-in microcircuitry interact electronically with electronic systems in the tables to enable the casino to oversee the exact amounts wagered minute by minute and quickly discover any statistical deviations from expected results; and roulette wheels are routinely monitored to detect any imperfections.
Casinos can be found around the world, and in many countries have a reputation for glamour and excitement. The Bellagio in Las Vegas, for example, has long been a magnet for celebrities and high rollers alike. Its lavish interior design, dazzling lighting, and breath-taking art installations are just some of its attributes.
The word casino derives from the Italian for “little house,” and the world’s oldest casino was established in Venice in 1917. Other famous casinos include the Monte Carlo in Monaco, Circus Maximus at Caesars Palace in Las Vegas, and the Wynn in Las Vegas. Many American states amended their antigambling laws in the 1980s to allow casinos, and casinos also appear on many Indian reservations, where they are not subject to state laws.
