Online casinos, also known as Internet casinos or virtual casinos, are online versions of traditional casinos. Online casinos are popular forms of online gambling. They allow gamblers to play the casino games they would play in a physical casino over the Internet. Besides being easy to use, online casinos also offer more features and entertainment than traditional casinos.

Casinos vary in style, but are all designed to be entertaining. Many casinos specialize in inventing new games and offer a wide variety of games. The games vary from casino to casino, though most games are regulated by state laws. For example, a French casino will have a lot of baccarat, which is very popular in France.

Casinos also have elaborate security measures in place. These measures include surveillance systems that allow security personnel to monitor the entire casino at once. For example, cameras mounted on ceilings and windows watch the casino floor. They can also be adjusted to focus on certain patrons or situations. The video feeds are recorded and can be reviewed later to detect any unusual behavior. In addition to video cameras, computer chips are used to randomly determine the payouts of slots.

The house edge varies from game to game. Blackjack, for example, has the lowest house edge (as low as 0.28%), while baccarat has the highest. The house edge affects the size of the potential payouts.
