A casino is a gambling establishment where people can gamble cash or casino chips on games of chance or skill. These games are sometimes called table games and can include card games like poker and blackjack, dice games such as craps, and wheel games such as roulette. Table games require strategic thinking, decision making skills and often luck as players compete against each other. They encourage socialisation and can be very enjoyable to play.

Casinos generate billions of dollars for private companies, investors, and local and state governments. Despite this, they are still considered illegal in many areas due to high levels of crime. Casinos employ many security measures to prevent their patrons from cheating or stealing, either in collusion with each other or independently. They also use various technological measures to monitor the activity in their facilities.

Many casinos are famous for their opulence and glamorous atmosphere. The Bellagio in Las Vegas, for example, is renowned for its fountain show and luxury accommodations. Other famous casinos include the Monte Carlo in Monaco and the Casino de Lisboa in Lisbon.

Casinos are usually large buildings that house a variety of gaming tables and machines. They can also be found in racetracks and other venues where gambling is legal. The majority of modern casinos are operated by private companies. Some are owned by Native American tribes. Some are based in cities like Las Vegas or Atlantic City, while others are located in remote regions.
