If you only ever play at one online casino you may never have noticed that online casinos can look very similar to one another even to the extent of having the same casino games which is particularly noticeable in the casino slots section. As an example take a look at All Irish Casino and No Bonus casino and you will see that the layout and casino games are the same but the branding is obviously different and they may actually have nothing to do with other but they have one thing in common and that is the casino software which is being used. Anybody who knows anything about the computer world knows that it is the software that runs everything and online casinos are no exception but online casino software is a very specialised business and most if not all online casinos do not develop their own casino software, not even the big players such as Paddy Power casino. There are in fact only a handful of casino software suppliers which include names such as NetEnt, Playtech, Microgaming, Wagerworks and Chartwell and these supply possibly 80% or more of all the online casinos that are available to the Irish casino player so it really is no wonder that some online casinos can look similar to others. Far from being a bad thing this is in certain areas an advantage such as progressive jackpots. When one casino software supplier is providing software for several online casinos the jackpot games are being played in all of those online casinos simultaneously which means that all of those online casinos are contributing to the jackpot which consequently builds much faster than would be the case if there were just a single online casino. Even if you are happy with the online casino you are using you may still be able to find the same casino games at a different online casino.
