As with almost all internet businesses online casinos depend for their success on the quality and ease of access of their website. Many new entrants to the world of online casino games are therefore surprised to find that when they log on to several online casino sites for the first time that some look remarkably similar, both in layout and in the casino games they offer. This is because many of the online casino operators employ one of the four major online casino software suppliers to construct and manage their sites, with the result that they will be using the same software as others in the sector. Clearly from our point of view as customers of the online casinos there are advantages in these companies using tried and tested casino software, particularly when it comes to the security of our personal banking details, and many would also argue that the similarity of the online casino graphics is not really a problem because a roulette table for instance is the same wherever you play. The real problem if there is one lies in the range of casino games, particularly the slots. It is the online casino software suppliers who design the casino games and negotiate any copyright issues associated with using famous cartoon characters or television programme themes and big film heroes, so the slots games they supply to their online casino customers are bound to be the same. There are online casino operators who do not use one of the big four casino software companies, notably Paddy Power and the All Irish casino as far as we in Ireland are concerned, so we are lucky that we can easily find a different range of casino games on both of these Irish based online casinos. There is of course a huge range of casino games available online so perhaps it doesn’t matter that some online casinos feature the same games, but it is interesting just how powerful these casino software companies are in the online casino gaming sector.
