How do you know whether you may trust online casinos? Will they pay up when you win? How do you know that the games are not fixed? After all when the games are digitised they don't have to be random to appear random. Online casinos could fix it in order that the odds are much more favourable to them than they appear. What might seem like bad luck could be a complex algorithm generating the results that the home needs to win based on your choices.

Obviously however, if as a company you are intending to be in business for the long term then you must have the trust of your clients. If you operate a casino that no-one trusts then you will have no gamblers. And no gamblers means no profit, which means your business goes under. To these ends nearly all of online gambling sites, including online casinos, utilise random number generating software from well known and trusted companies like Wager Works, Micro Gaming, Play Tech and Cryptologic. In the event you are gambling online for the first time or trying to find a new site to join then it pays to do some research in to the company. Find out how long they've been established for if you can. A site which has been operational for a while will probably be legitimate because it will not take long to lose your customers or get shut down if you are not. Check what random number generating software they will use.

Having said this there are actually a small range of rogue casinos available. They are generally short-lived, aiming for the 'quick kill' and after that disappearing as quickly because they arrived. There have also been allegations of cheating made against larger online casinos such as Casino Bar. Allegations of cheating have also been made against several of the random number generating software companies, however they have never been confirmed. Series of random events do occasionally generate apparent patterns, it's to be mathematically expected.

You will find quality online gambling agent casino blacklists containing lists of rogue casino sites in order to avoid. However it should be noted that different authors of these blacklists have different opinions on why casinos have made their lists. Read the reasons given for each casino's blacklisting and decide for yourself if you want to play there.
