I have been programming and designing Online Casinos for over 6 years and I can honestly tell you that I have seen it all. I can’t really speak for the companies that I never worked for but I still have more than enough inside information on 99% of all casinos online I guess having a lot of friends in the same professional field does pay off at times sa gaming .
Anything you could possibly imagine is being done with Online Casinos. From simple things like online slots having an extremely low payout percentage to the most complex of “intelligent chance altering”, it is all being used right under your nose and most people have no clue. Most people trust the Casino and just tell themselves that they have a “bad streak”, blame themselves or blame it on god not liking them for all I know.
The most common scam is the low payout percentage. It is used in virtually every game/program. All this does is alter the number of times the player(you) gets paid. There is a minimum legal percentage of payouts for slots that needs to be followed by all casinos, but there is almost no way that you could prove that they’re skimming on the payouts. In order for you to prove that a casino is not paying out the minimum percentage, you would have to track thousands of spins, all of your wins and losses, meticulously document everything and prove that you actually did all of this.
Aside from that, you would have to literally spend tens of thousands of dollars just to get a glimpse of the whole system because the higher your number of total spins, the more accurate your end result will be(percentage) and you would need at least 10,000 spins to have any accuracy. It of course needs to be in real-money mode since you can’t really do it in play-money because the odds in that mode are a lot different play-money mode actually has a player advantage to reel you in.
