Nowadays almost all successful businesses need an internet presence of some sort, and many of course are totally dependent on the internet as the only contact with their customers. This dependence on a good efficient web site has therefore spawned a whole new industry in the design and installation of the software necessary to manage every web site, whatever its purpose. In the case of online casinos the casino software is even more important because the software not only controls and manages the commercial aspect of the online casino site, it also produces the product that is being sold on the site. We refer of course to the casino games we all enjoy playing. Even the well-established casino games such as roulette and blackjack differ in appearance from one online casino to another because the casino software supplier is responsible for the graphics, but it is when we come to the slots games that the casino software has the biggest influence. All the slots games we find in the casino games range at every online casino have been designed by the casino software supplier, who is also responsible for any copyright issues associated with the themed games. The choice of casino software supplier is therefore the defining factor in the success of any online casino, which is why the leading casino software company Playtech has grown so quickly and become so influential in the online casino sector. There is of course a drawback to one software company becoming so dominant, and that is the obvious similarities we see from one online casino to another. The casino games are often almost identical as are the graphics, so our choice becomes more limited. We are fortunate in Ireland in that our most popular Irish based online casinos, Paddy Power and the All Irish casino both use different casino software suppliers which ensures we have a better choice of casino games.
