Ideally, no. If a casino is using something to manipulate their users, I am pretty sure that will go against some laws regarding businesses or companies and would also go against the rights of a consumer. So, legally that’s probably a headache for casinos.

I wouldn’t say it’s totally impossible. They can check our gambling history and they could do something to make sure it’s them that takes the most profit and not us. However, this kind of accusation is difficult to prove so it would be pretty huge to drop such.
It is possible that they have a system that lets new accounts get a taste of winning however it is also entirely possible that it is just a coincidence that we are putting too much thoughts into. I mean, there is something called “beginner’s luck” for a reason.
