Online Casinos, as the very name suggests refers to online versions of traditional casinos where the gamblers can play on the casino games through the internet. The odds and payback percentages offered by such online casino games are comparable to the land ones. It is observed that certain online casinos offer higher payback percentages for slot machine games whereas some prefer the publication of payout percentages on their website. The issue of trust and reliance are often questionable and are sometimes put to doubt.

The companies that sell or lease out such online casino games are Real-time Gaming, Micro gaming, Crypto logic Inc. and Partech. They profess to use programmed random number generators so that the numbers, cards or dice appear randomly, failing which the entire motif behind such gambling operations goes futile. The three types of online casinos that can be divided on the basis of their interface are as follows:
· Web—based casinos
· Download –based casinos
· Live Casinos(A comparatively recent invention)
Now , moving to the definition of each of these to enhance the understanding of such casinos, it can be said that Web– based casinos are those in which a gambler/player can play a casino even the executing the process of software downloading to one’s own computer. On the contrary, download—based casinos, as the term implies, involve the downloading of the software to one’s own computer in order to proceed with the gambling procedure.

Although, the initial process of installation and downloading of the software is a little time consuming, yet, while gambling, these casinos run much faster than the Web—based casinos since the graphics and the sound programs are situated within the software client unlike the Web—based casinos where one has to use these applications from the internet, thereby making it slower. The third type or the live casinos, a new introduction into he world of online casinos, are such, that the players or the gamblers can communicate with the games being played in the outside world and even converse with live dealers placed at various casino studios sprawled across the world.

Online casinos are online counterparts of the land based casinos operating at various parts of the world.
