In a week when yet another well known high street chain has called in the Administrators, our shopping habits have once again become the focus of attention. It Is now clear that many more of us are increasingly shopping online, with price and convenience often being the deciding factor, but online shopping also raises other questions not least of which is security relating to our personal details. Anyone who has used the internet for shopping or indeed many other activities will know that some web sites are excellent and easy to use whereas others can be very frustrating. A web site is only as good as the software used to manage the site, and the same applies to online casinos. The online casino software it uses is probably the most important decision an online casino operator will make, which is why the provision of casino software is a very specialised field dominated by four big companies, namely Wagerworks, Microgaming, Chartwell and Playtech. These companies are so important to the online casino operators that William Hill have gone to great lengths to acquire Playtech and so control this area of their business. From our point of view as online casino customers, the casino software is what defines the online casino site layout and graphics, and more importantly the security and privacy of our online transactions with the site. The casino software is of course also responsible for the range of casino games available on the site, and this is particularly noticeable with the slots many of which you will find replicated at several different online casinos because they have used the same casino software supplier. We have to assume that this is why Paddy Power have opted to use one of the smaller casino software suppliers, Cayetano which incidentally they also own. Most of us do not really take a great interest in the casino software sector of the online casino scene, but there is no doubt that we choose an online casino for the range of casino games and their reputation for safety, security and fairness, all of which is down to the quality of the casino software.
