The only game worth playing in a casino. In all the other games, the house has a bigger advantage. Some people use a method called card counting to know when to bet high and when to bet low.
Also, the combination of 2 cards equaling 21 in the game.

Blackjack is also called twenty-one.

Blackjack is not as easy as AYB is trying to say it is.
