Everybody uses their chosen online casino because they like the layout or the types of casino games which are on offer or simply because they feel they have a better chance of winning but in actual fact it is not the online casinos that are being chosen but the casino software that is in use. Online casinos have long since given up trying to develop their own casino software and instead leave it to some specialised companies from which they then lease, rent or have some other arrangement with to use the software on their site. This is why you may have noticed that some online casinos look amazingly like others even offering the same range of games and the answer is that they all use the same casino software which is then branded according to the end user. Bet365 and BetFred are examples of this. There are really only a handful of major casino software suppliers which include Chartwell, Microgaming, NetEnt, Playtech and Cryptologic so the chances are that the online casino you have chosen is using one of these and that is in fact a good thing as these are major companies who produce excellent casino software that are pretty much guaranteed to be safe and fair. The use of one of these casino software suppliers also enables the smaller online casinos such as All Irish Casino to compete with the big boys as they use common casino software (NetEnt in this case). It is also interesting to note that it is the casino software providers that control the huge progressive casino jackpots that are available which enables those jackpots to grow much faster as there is more than one online casino contributing and it also explains why an online casino is happy when you win one of those slots jackpots as it is at no cost to the online casino itself.
