Also referred to as internet casino or virtual casino, online casinos enable gamblers to play and wager without necessarily going to a casino. They usually offer a higher percentage of paybacks and odds as compared to land-based casinos and a higher payback percentage on slot machine games, and also publish the audits. Considering the use of a random programmed number generator, some table games such as blackjack have a well-known house edge, with the payout percentage stated by the rules of the game.

Download-based online casinos

In order to play the games offered by the casino, the client is required to download the software. The software then connects to the casino’s service provider handling contact without browser support. Downloadable online casino apps are known to run much faster as compared to web-based online casinos because the sound and graphics programs are cached by the software’s client instead of having to load from the internet. The initial download and installation takes time just like any other download.

Web-based online casinos

Also known as flash casinos, they are websites where the users play casino games without having to download software onto their local computer. Represented in the browser plugins as Java, Macromedia Shockwave or Macromedia Flash requires browser support. The bandwidth is needed for loading through the web via the plugin all graphics sounds and animations. Other online casinos accept gameplay through an HTML interface, with devices that cannot play flash games since the technology is not supported by Apple devices such as iPad, iPhone, and iPod.

Live dealer casino games

These feature a human dealer on a casino gaming table running the game in real time. The dealer is seen using a live streaming video link. The players can make betting decisions through a console on their computers and communicate using a text chat function. The results are translated using data by software using optical character recognition technology (OCR), which enables the players to experience the game just like there are in a casino.
