How do casinos stop card counting in blackjack?

Casinos use various tricks to stop card counts. Change the number of hands played by shuffling more cards to play together or using fewer cards. Casinos may also set strict betting rules to make it difficult for card counters to make big money.

Casinos watch card counters closely to catch them. The more you win, the more attention you pay. A smart dealer can tell if you are counting cards by looking at the bets and how you play. If you think something looks suspicious, report it to your boss, and you can even check the security cameras to see if they are really counting the cards. The casino then decides what to do next.
