I can't prove whether they're rigged or not; only a serious investigation by the appropriate authorities can tell. But we know the house always has the edge. Casinos don't profit from how much you bet, they profit from how much you lose. Therefore, I can say that their greatest interest is for you to lose. But first, they'll let you have that taste of victory, because that way, with confidence, you'll bet more money.
This is the biggest what if in online casino. No one will know if they are cheating since they are operating online while their customers is from different country that can’t demand an investigation internationally.
Unlike the physical casino which all games is being audited by regulators on the country they are operating.
That’s why it’s important to play on reputable casino so that you can minimize the risk of playing rigged online gambling games.
