Good casino software makes all the difference between an OK casino and a great one. Of course there are other factors to take into account when choosing where to gamble online , such as customer service and speedy withdrawals, but at the very heart of the online casino is the software that powers it. It is essential that the software itself is reliable, fair and random.



There are several major suppliers of online gaming software, and a few lesser known ones. Some casinos run proprietary software, and if you choose a casino which runs its own software then you need to ensure it has been thoroughly tested for fairness and randomness. Luckily, very few casinos run rigged software, but if you stick to one of the casinos powered by the bigger providers, you can be assured you are being dealt a fair game.
