It is not something which is often thought about by those who enjoy online gambling but without the software none of the programmes would work and whereas most of the online gambling providers will have bespoke sports gambling software the casino software will almost certainly have come from one of only a handful of specialist companies. Casino gambling software for the major online casinos is a very complicated business which has resulted in specialisation and the emergence of companies such as Microgaming, NetEnt, Chartwell, Playtech and Cryptologic. It is difficult to say which is the best casino software as they all have their own games and it becomes a matter of personal choice and it is also possible that an online casino uses different casino software for different parts of the casino such as casino games and casino slots. If you like casino gambling and you play at more than one online casino you may have already noticed that the layout of casinos can be very much like each other and the games can even be identical even though the branding on screen is different which is of course because both online casinos are using the same casino software. When it comes to gambling on progressive jackpot slots this is a good thing as what happens is the casino software company takes responsibility for managing the progressive jackpot across all casinos carrying that game. For each spin a small amount of money is contributed by the online casino to the jackpot and when it drops it is paid out from the pool. In this way the jackpots can build up much faster and as we know can reach into the millions of Euro. In truth, as long as you enjoy your online gambling it probably does not matter too much which casino software is being used except beware those that write their own.
