What most people will not realize, mainly because they will never think about it, is that when choosing your online casino you are in effect choosing an online casino software provider but whereas you will know the name of the online casino you will probably not know the name of the software provider. The truth is that as long as you are happy with the selection of games which are made available and you are happy with the graphics and sound it probably does not matter too much who the provider is of the casino software as long as you have selected one of the major online casinos which we list here at casinos.ie. Casinos.ie lists only those casinos that we know use trusted casino software that guarantee you a fair game and also guarantee your data security. Smaller online casinos, of which there are plenty will sometimes write their own casino software but this is a specialised business in which there are only a handful of major players and you should ask yourself why it is that the major online casino operators such as those recommended by casinos.ie purchase or lease their software from the major suppliers. The major casino software providers in no particular order are Microgaming who are responsible for developing such slots as King Kashalot and Major Millions, Playtech which is used by a number of the major online casinos, Wagerworks who count among their clients Paddy Power and 888 casino, Cryptologic based here in Ireland and Chartwell who were originally established in Canada but now operate all over the world. Many online casinos will not restrict themselves purely to one casino software provider but will instead use what they consider the best software for the application, so slots might be supplied by one software provider but poker by a totally different company. Casino software is important but stick to those online casinos that we list here at casinos.ie and you will not go wrong..
