RNG issue

[simlor]

I want to know more how this RNG (random number generator) works in the gambling sites.
Do they just let it run once they set it up? who tests it to see that its really random?
I also heard they can intervene at any time and set it to reward (or punish) any player they like, and it can't be detected

Ya some guy I played with at rummyroyal.com told me than, but it doesn't really matter to me because I play with play chips.
A couple times I bet a few real chips but I never take it too far with that site.

Typical conspirecy theory.
If you only had a clue as to how much the casinos spend on some external lawyer to give them a document that proves the cards are random.
Of course some sites are not to be trusted, but as long as you go to the biggest places you should be safe (or as safe as in a real casino).
