A casino, also known as a gambling house or a gaming establishment, is a place where people can play various games of chance for money. Gambling is a popular activity around the world, and casinos are a common source of entertainment. Casinos can be found in many countries, and some are famous for their glamorous atmosphere or architectural design.

There are several different kinds of casinos, and each one has its own unique culture. Some are family-oriented, while others cater to the needs of big bettors or those seeking a luxurious getaway. In addition to the usual array of table games and slot machines, some casinos offer more exotic forms of gambling such as sic bo (popular in China), fan-tan, or baccarat. The largest casinos are often built into or combined with hotels, resorts, restaurants, retail shops, and other tourist attractions.

The casino industry is regulated in many places. In some cases, the government regulates the number of games offered and the minimum age for admission. In other instances, the casinos are regulated by independent agencies. Casinos may also use technology to prevent cheating or stealing by patrons. For example, betting chips have microcircuitry that allows them to communicate with the electronic systems that monitor the amount wagered minute by minute, and roulette wheels are electronically monitored for statistical deviations that could signal tampering.

While Las Vegas and Monte Carlo are perhaps the most famous casinos in the world, there are many others. For example, the Bellagio in Las Vegas has an iconic fountain show that attracts visitors from all over the world. Other famous casinos include the Casino de Monte-Carlo in Monaco, and the Casino Lisboa in Lisbon, Portugal.
