The house always wins is enough reason to never go near any casino
They can kick out anyone they want.
No, they’ll kick you out for doing it without a machine too, fuck I mean there’s a movie on it.
But I call bullshite because they made card counting useless by playing with multiple decks.
Automatic shufflers and using 3 or 4 decks, make the benefit from cardcounting almost zero.
How is it allowed? It’s their casino. They’re there to make money off you, which is why everything stacks in their favor and any games involving any actual skill are hobbled severely and using any gets you banned.
Now if you ask “how are casinos allowed” I’ll ask right along with you. They are immoral and predatory - not literal fraud but it gets close, and either way it’s treating people with addiction as cash cows.
Generally speaking, a blackjack table will run with 5-10 decks in the shoe. So counting isn’t as effective, because the odds are diluted by volume.
Also, folks will often use aids to count cards, because keeping track in your head is difficult. What most people get thrown out for are carrying these aids.
This here is the answer. Unless you’re scouting a table for a long while, you generally won’t know how many in the shoe. That, mixed with the fact that mentally keeping track of 250-500 individual cards, not only is near impossible without an aid; you would also only have so many opportunities to “know” what cards are left. Thus, the 30 cameras pointed at you and identifying that you’ve been playing the same table for hours, they’re going to know.
In reality, the casino industries current weak point is their electronics, specifically the slots. The software running on those things has been proven to be about as vulnerable as a payphone, and people have been caught running schemes on them.
