The casino business has a long history. It began in Venice, where the government authorized the first official gambling house. These houses were called ridottos and provided a place where rich people could play high-stakes games, often with their families.

Since then, other European cities have also developed gambling palaces, including Las Vegas, and the United States has become a major market for the industry. This is especially true in Nevada, which has been the most prominent gambling destination since the 1950s.

In addition to the usual games of chance, some casinos also offer a variety of traditional Far Eastern games. These games are primarily sic bo, fan-tan and pai gow, but sometimes other games are found at casinos, such as two-up in Australia or banca francesa in Portugal.

Most casinos have a manager to oversee the operation of the casino. They must be licensed to work in the gaming industry, and they usually have a bachelor’s degree.
