I would recommend to stay away from all online Casinos, the houese (owner of the Casino) always wins.
it's a business that's why they are running an online gambling, if the owner will not earn having that what will be the reasons for them creating a gambling website?
If you think that the game is not probably fair you can play other games such as betting or poker.
Chance of losing and winning is already known by gamblers they are the one who will decide if they want to play.
It's a business though they still need to be fair to their bettors although owners needs to earn still this should not compromise the fairness of the game since this could make them scammers, but if we want to play without basing our luck we can actually select the skill based games so that people have great chances to win.
And also I don't like the generalization of all online gambling sites since not all is running on not fair business since there are few running good for several years.
