In the beginning of online casinos most providers were tempted to create their own casino software which they did with varying degrees of success but today the whole area of casino software has become very specialised and they are really only a handful of software companies that provide casino software to the majority of good online casinos. In truth it probably does not matter too much which casino software your online casino uses as long as you are using one of the better known online casinos such as those recommended here at casinos.ie and you are happy with the graphics and games which that software provides. One of the most popular casino software companies is Microgaming which is used amongst others by Spin Palace Casino and Ladbrokes casino; Microgaming’s claim to fame is an impressive range of progressive jackpot slots including the well known King Cashalot which paid out a cool €1.5 million earlier this year. When a casino software provider has several customers these progressive jackpots build up to huge amounts of money and makes play very interesting. Another of the major players in the casino software industry is Playtech who have been around for some years. Playtech has fairly recently signed a joint venture with William Hill Online to use the casino software but there are others such as Bet365 and BetFred who also use the software extensively. Irish online casino operator Paddy Power tends to use Wagerworks, another well known casino software provider and we believe that 888 casino also uses the same software for the slots offering. It is not unusual for an online casino to use different casino software for different parts of their offering such as slots from one company but poker from another. You may never know which casino software is used by your online casino but it can be important..
