Let’s be clear, “card counting” is the simple use of your brain. It is not illegal anywhere because using your brain is not illegal. For a casino today to still threaten confiscation of winnings for using your brain is idiotic. How many lawsuits do we have to win until someone changes the wording in these Casino House Rules?
It is OK for casinos to not like it when players “count cards”. It is OK for casinos to back off proficient players. But to threaten players using wording as shown above is simply bad business.
