Choosing an online casino to play your casino games is an important step and can have a significant effect on your continued enjoyment of the casino gaming experience. Apart from choosing a brand name which they know and trust, most people make their selection based on the range of casino games being offered and the graphics and layout of the site. All of these factors are important, and they are all dependant on the online casino software the operator has chosen to use. Even the trust element is down to the efficiency of the chosen casino software in terms of data protection, and this is why most of the major online casino providers tend to use specialised casino software companies to design and manage their sites. There are of course a number of software companies providing this essential service to the online casino industry, but the major players are Wagerworks, Microgaming, Playtech and Chartwell, who between them supply most of the well known online casino operators. This of course explains why many casino games are presented in an identical format on a number of different online casino sites, and why many of the slots can also be found on more than one site having been developed by the casino software supplier and rebranded to suit the relevant site operator. The importance of these specialised casino software suppliers to the online casino industry cannot be overstated, and explains why the latest trend within the gaming industry is for the large online casino operators to take over or merge with one of these specialist companies. William Hill for instance already own Playtech, and Paddy Power have recently announced a takeover of Cayetano, a casino games software company based in Bulgaria. One has to assume that this trend will continue.
