A casino (also spelled caino or kazino) is an establishment for certain types of gambling. Casinos are often built near or combined with hotels, restaurants, retail shops, and other tourist attractions. In some countries, casinos are licensed by government authorities.

A wide variety of gaming options is available at most casinos, including table games, slot machines and poker. Most of these games are conducted by live dealers. Several casinos are known for their luxury and elegance. The Bellagio in Las Vegas, for example, has been featured in countless films and is considered to be one of the most beautiful casinos in the world. Other famous casinos include Monte Carlo in Monaco, the Casino de Lisbon in Portugal and the Casino Baden-Baden in Germany.

Casinos are generally carefully designed with security in mind. They use cameras to monitor activity and employ a staff of security personnel who supervise the games. Some casinos also use advanced technological measures, such as chip tracking or roulette wheels that are electronically monitored for statistical anomalies. Casinos often hire mathematicians and computer programmers specialized in gaming analysis to assist with these tasks.

Many casinos host live entertainment, such as concerts and stand-up comedy acts. Caesars Palace in Las Vegas, for instance, has been home to a number of entertainers, from Frank Sinatra to Celine Dion and Madonna. The casino is also famous for its elaborate fountain show, which is synchronized to music and lights. In addition, the Caesars Palace Arena is a major venue for sports events and has hosted performances by artists such as Rod Stewart and Van Morrison.
