What is a Casino?


A casino is a place where people can play games of chance for money. Gambling is the primary activity in a casino, although there are also many other types of entertainment. Casinos are often combined with hotels, restaurants, retail shops or cruise ships. Some casinos are known for staging live entertainment events, such as stand-up comedy or concerts.

Most casinos focus heavily on perks to encourage and reward their gamblers. These include free shows, rooms and meals. High rollers are pampered in special rooms that are separate from the main gambling floor. In the 1970s Las Vegas casinos were famous for their deeply discounted travel packages and free show tickets.

The vast majority of casino revenue comes from gambling, and most casinos are virtually guaranteed to make a profit every day. The mathematical expectancy of each game is analyzed by specialists in gaming math (or by computer programmers). Casinos know both the expected return on each bet and the variance for all their games, which helps them determine how much to risk on any given spin of the wheel or deal of cards.

Something about the nature of gambling seems to inspire people to cheat, steal or scam their way into a jackpot, and casinos spend a great deal of time, effort and money on security. The routines and patterns of all casino games are studied by security people, who look for anything out of the ordinary. For example, dealers shuffle and deal cards in a certain pattern and players bet in particular spots on table games. These habits are easy to pick up on, and security personnel can alert the pit boss if they think a player is trying to manipulate the game.
