The casino software in use at your chosen online casino is probably the most important factor in whether you enjoy the experience of online casino play or not and yet most people do not know which software the casino is using. This is in part due to the online casinos not providing the information in a clear manner but there is also an argument that says that it is the online casino provider that you are choosing so the casino software writer is not relevant. In actual fact there are far more online casinos than there are casino software packages which is why, if you have looked around, you will find online casinos that look very very similar to each other. As an example take a look at Bet365 casino and BetFred casino and you will see from the layout and even the list of casino games that they are using the same casino software. The major players in the casino software market are NetEnt, Playtech, Microgaming. Cryptologic and Chartwell with Microgaming and Playtech probably being the most used although NetEnt or Net Entertainment to give them the correct name is certainly gathering popularity probably due to some different casino games particularly in the casino slots area. If you would like to take a look at NetEnt software you can find it at All Irish Casino. The fact that several online casinos use the same software is of course not a problem and indeed it can sometimes be a distinct advantage in the area of progressive jackpots. You will find several progressive jackpot slot games are available at different online casinos and all of these online casinos contribute to the same jackpot which means that it builds up far quicker and to a higher level than would be the case if each online casino ran its own jackpots.
