The one common factor with all internet sites, whether they are retail websites, information sites or online casino sites is the need for good efficient software. This is particularly true in the case of online casinos because the casino software is not only responsible for managing the financial aspects of the site and the graphic design of the content, it also defines the casino games which are available to play on the site. The vast majority of the casino games offered by our online casinos are versions of slots and video slots, and it is the online casino software companies which design those casino games and negotiate any copyright issues associated with the characters used in the games. There are several major specialist online casino software companies, although one in particular is on track to becoming a dominant force. Playtech casino software is now used by William Hill, Betfred, Bet365 and recently Ladbrokes, which although the software is of course excellent also has the effect that these online casino sites look remarkably similar with virtually the same casino games on offer. Any casino games player looking for something different now needs to seek out an online casino which uses a different casino software supplier or one which develops their own software. Fortunately both of the favourite online casinos used by Irish casino games players, namely the Paddy Power and All Irish casinos use different casino software, as does the new No Bonus casino, so there are plenty of different casino games available for those prepared to look for them. This of course means that although most online casinos now offer well over a hundred casino games, many of us choose to register with more than one online casino simply to get access to some exclusive casino games.
