A casino is an establishment for certain types of gambling. Casinos are often combined with hotels, resorts, restaurants, retail shops, and other tourist attractions. They may also be located near or combined with recreational facilities such as golf courses and spas. In some countries, casinos are licensed and regulated by the government. In the United States, the legality of casino gambling varies from state to state. The number of permitted casinos can vary greatly, as can the age at which one can gamble there.

The word “casino” is derived from the Latin casinus, meaning a house or hall for music and dancing. In the second half of the 19th century, it came to refer to a collection of gaming or gambling rooms.

In games that have a skill element, the casino’s mathematical expectancy (also known as the house edge) is based on optimal play. Optimal play is determined by considering the game rules, number of decks used, and even the dealer’s skills. These calculations are performed by specialized mathematicians and computer programmers, who are known as gaming analysts.
