When logging onto an online casino to play your favourite casino games it would be unusual if you were thinking about which online casino software you were about to use and as long as you are playing at a reputable casino it is probably not too important as long as you are happy with the games you are playing. The fact is however that online casinos rarely write their own software but have contracts with specialised companies such as Microgaming casino or Playtech casino to name a couple of the larger ones. These casino software suppliers not only write the programmes for the games but they also include in the software the banking modules which control the security of the data that you submit and it therefore becomes important that you are using a company you can trust. The two we have mentioned here are of course not the only trustworthy suppliers; Paddy power for example have chosen to use Wagerworks casino software whilst Bwin have selected Chartwell casino and there is no doubt that with major names such as those as customers these software suppliers are without doubt among the top few. The fact that several online casinos may use the same software supplier also explains why some sites look remarkably similar to each other; for example Betfred and Bet365 both use Playtech casino and the games offered by each of these operators are nearly identical as are the layouts of the games. At the end of the day, if you are happy with the online casino operator that you are using you should not need to worry about the software supplier; leave that to them to sort out..
