In the carding game it is usually between three to four cards when someone wants to start. Take for instance if you want to play what card games it is usually begins with four cats and a general card to play on among the players. The same thing also goes for the leave jacket card games which usually starts with foiur cards. But I don't know about the blackjack because I have not witnessed it when it was started. So how many cards to start with in blackjack?
