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).

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).

The more complex programs like the "intelligent chance" are virtually impossible to prove(short of having the system's blueprint). That's right, there is nothing that you would be able to do to detect it, let alone prove it. Creepy ain't it?

The way it works is that it's a smart-program much like it's name implies. It learns and studies. It collects information from you about your playing habits, your betting amounts at certain times under certain circumstances etc. It basically reads you. 90% of the time it knows your move before you even make it. That isn't even the worst part. The reason why it collects this information about you is for the sole purpose of knowing how and when to squeeze the most money from you. For example, losing $500 after I just won $400 is sure to make me keep going to get the $100 back while you might be more willing to keep playing after having lost that same $500 through a slow up-and-down game(imagine this thing after five years of playing, it literally knows you better than your own mother). It all varies from person to person, or should I say from one personality to another because that is exactly what the program is learning about you... what your personality is like, for the sole purpose of: "which way am I going to squeeze the most green out of this sucker?".

I could write a whole book about this subject(that would be a treat, putting 90% of Online Casinos out of business with one book, makes you almost feel bad for them). Like I said before, there is nothing you can imagine that the Online Casinos haven't cooked up before you. This is the reality, the sooner you come to accept it, the better you are. There is nothing you can do to find out which Online Casinos are good and which ones are, well, monsters... except be at the right place at the right time, this is the place and now is the time.
