A casino is a facility for certain types of gambling. In addition to providing gaming tables and machines, some casinos offer entertainment shows and restaurants. In some cases, they are combined with hotels and resorts. They are also sometimes found on cruise ships and in military installations.

In the United States, casinos are usually located in urban areas or tourist destinations. Some cities are better known for their casinos than others, such as Las Vegas and Reno. Other famous casinos include the Monte Carlo in Monaco, the Hotel Lisboa in Macau, and the Circus Maximus in Paris. The Casino Estoril in Cascais, Portugal, was a favorite haunt of spies and dispossessed royalty during World War II and inspired Ian Fleming’s James Bond novel, “Casino Royal”.

Besides the usual range of table games and slot machines, many casinos have sports betting facilities. The MGM Grand on the Las Vegas Strip, for example, has 60 large plasma televisions where you can flick a few coins on American football, boxing, and martial arts. Asian casinos tend to focus on traditional Far Eastern games such as sic bo (which spread to European and American casinos in the 1990s), fan-tan, and pai gow.

Some casinos employ mathematicians to study house edge and variance, and to develop strategies for players to minimize their losses. These are called gaming mathematicians or analysts. In games where players compete against one another, the casino makes money by taking a percentage of each pot or charging an hourly fee for dealing cards.
