A casino is an establishment for certain types of gambling. It is often built near or combined with hotels, resorts, restaurants, retail shops, cruise ships or other tourist attractions. The most successful casinos make billions of dollars each year for the companies, investors, and Native American tribes that own them, as well as state and local governments that collect taxes and fees from gamblers. These revenues are used to improve the facilities and attract visitors.

Casinos are designed around noise, light and excitement to entice people to gamble. In addition to games of chance, some casinos offer sports betting and horse racing. In most cases, the house has a mathematical advantage over the players and this is known as the “house edge”. In table games such as poker and blackjack the house takes a small percentage of bets, which is known as the vig or rake. Unlike lottery games, casino gambling is social in that patrons are usually surrounded by others and the noise, lights and activity create an enjoyable experience.

Many people consider casino gambling to be a fun night out with family and friends. In fact, according to a survey conducted by Peter D Hart Research Associates and the Luntz Research Companies, 92% of respondents go to casinos with their spouses, families and friends. Many casino patrons also enjoy their gambling experiences with coworkers and business associates. In addition to attracting potential customers, casinos often give away complimentary goods and services, known as comps, to frequent gamblers. This can include everything from free hotel rooms and dinners to show tickets, limo service and airline tickets.
