A casino is a building or room where gambling games are played. The games generally involve chance and some have a skill element, such as blackjack and video poker. The majority of casino games are table and card games. Most American casinos feature a variety of popular games including roulette, craps, baccarat and poker. Many also offer traditional Far Eastern games such as sic bo and fan-tan, as well as games specific to a region or country like two-up in Australia, boule in France, or pai gow in China.

Gambling is a pastime and a social activity for many people. Unlike lottery tickets or online casino games, where people gamble anonymously and independently of each other, casino gambling is a highly social affair. People are typically surrounded by other people and often shout encouragement, especially at the table games of craps and poker. The pulsing beat of music and the flash of lights create an energetic and exciting environment.

Casinos make money by charging a fee to gamblers called the house edge or vig. This fee, which is uniformly negative (from the player’s perspective) across all games, covers operating costs and gives the casino a profit. Casinos may also collect a fee from each bet placed on certain games, such as the rake in poker.

Because of this virtual assurance of gross profit, casinos are free to reward big bettors with extravagant inducements like free spectacular entertainment, transportation and elegant living quarters. Even lesser bettors are frequently offered comps such as free hotel rooms, meals and drinks while gambling.
