Loosing consecutively looks very normal, and that has ever attracted as much attention as winning consecutively will bring. Has anyone ever heard of any gambler who won so much from a casino consecutively that the casino flagged their account. I am imagining what will happen, What happens when a gambler wins too much say consecutively from a casino?
From movies about casinos I know that casinos monitor almost every player, and they have screens with graphs of these players' victories. And as soon as someone starts winning constantly, he immediately attracts the attention of the casino administration, and they immediately begin to monitor this gambler's game.
And I know that bad casinos can simply ask such a player to leave the gaming room without looking into it, or cancel the chips.
Casino will always monitor all of their members and make sure that their members doesn't do anything that can be a sign to cheat casino. The casino team can also check on some gamblers who wins for some time to see their account and the things that can happens is the casino team can asks them to do verification further. The bad casinos can block that members when they wins many times with big money because they don't want their money gone to the members hands.
Maybe there are some gamblers who can win consecutive and that is a big money and if they don't commit a cheat, casino will allow them to withdraw the money. And that will depends on the casino itself.
If a player wins a large sum once, it is considered luck and no casino employee will pay attention to it, but if it happens again, then the casino employees will start to study how the player managed to do it twice. Will it be an accident or a pattern. Because there is a risk that the player found unknown strategies or did something prohibited to win. Of course, casino employees may not disclose such a player and they can simply block him forever in their casino without any reason. We sometimes come across such stories, unfortunately, so I would carefully choose the casino in which I will play in advance for various reasons.
