When gambling online you will find the name of the gambling provider all over the screen and it looks like a unique site but if you are gambling at an online casino the sites from some online gambling providers look remarkably similar to others even though the name is different and this is because each of them will have an arrangement with the same casino software supplier. Online casino gambling software has become such a specialised business that virtually no online casino writes their own and a handful of companies such as Playtech, Wagerworks, Netent, Microgaming and Cryptologic have taken over and compete for business; in fact Netent was originally an online casino operator but became dissatisfied with the available casino gambling software and started writing their own only later to discard the casino operation and sell their casino software to others. The easiest way to spot that two online casinos are using the same casino gambling software is to look at the range and names of the casino slots as it is the casino software supplier that creates the images for the slots and has the agreements with, for example, the Marvel Comic Book Heroes. This is not a disadvantage to the online casino slots player as all users of the gambling software are contributing to the massive jackpots and as several online casinos are contributing, the jackpots rise much faster than would otherwise be the case. It is also not unusual for online gambling companies to use different gambling software suppliers on different parts of the site and even different areas within the online casino section but at the end of the day what matters is that you like the end result and get pleasure from your online gambling and you are unlikely to go checking which casino gambling software is being used as long as you like the gambling provider.
