What Is a Casino?

A casino is a gambling establishment that offers various types of games of chance and skill. Some casinos also offer food and entertainment. In some cases, these facilities are combined with hotels and other tourist attractions.

While lighted fountains, shopping centers and musical shows all lure patrons into the building, the real draw is games of chance like blackjack, craps, roulette, baccarat and slot machines that bring in billions of dollars in profits for casinos each year. These games, which are operated by live dealers and sometimes have an element of strategy, give the house a predictable long-term advantage over players, a fact that is reflected in the odds of each game, or expected value. Those who possess the skills to overcome the house edge in these games are known as advantage players.

The most profitable casinos in the world are designed to maximize gross profit through a combination of house edges, payout percentages and the rake taken from poker and other games of skill. Because of this, it is very rare for a casino to lose money on any day, even if every patron plays perfectly. In order to ensure this, the games are carefully analyzed by mathematicians and computer programmers called gaming analysts.

Despite these advantages, casinos still attract many patrons by offering extravagant inducements to big bettors. These include free or reduced-fare transportation, hotel rooms, meals and drinks, tickets to shows and limo service. Casinos also track their high-roller play and rely on their sophisticated surveillance systems. These often have catwalks in the ceiling and one-way glass that allow security personnel to view patrons at all tables and slot machines.
