Many Irish casino players never give a thought to the casino software that their online casino is using, probably thinking that the online casino provider has developed their own but in fact this is almost certainly not the case. Online casinos gave up developing casino software many years ago as it became more and more specialised so that today there are only a handful of good casino software suppliers and certainly all the online casinos listed at casinos.ie use one or more of those suppliers. The major names in casino software supply are in no particular order Microgaming, NetEnt, Playtech, Wagerworks and Chartwell and as long as your chosen online casino uses one of these you will be in safe hands. Whether you like the graphics and the range of casino games at your online casino will depend purely on which casino software they have chosen to use and if you play at more than one online casino you may have noticed that the casinos can look amazingly similar which is of course down to them using the same casino software. As an example, All Irish Casino, No Bonus Casino, and Freespins Casino all use NetEnt casino software so although the colours might be slightly different the casino games on offer will be the same. This multiple use of casino software can in some instances be beneficial to you. Casino jackpots and in particular slots jackpots are built up and controlled by the casino software supplier and not by the individual online casino so the more online casinos that are using the software the faster the jackpots will build. This also explains why it is that online casinos make a big play when somebody wins a large jackpot when using their site as they are getting the publicity of the big win but it is the casino software company which is paying out and not the online casino itself.
