Just like any other casino game, especially card-comparing games, Blackjack depends on luck by a great deal. However, it requires more than just luck to win in Blackjack. In 21, sheer luck and a wee bit of skills do the trick for you. Luck plays its role when the cards are dealt to you. When you’re lucky, you can score a perfect 21, other times, nowhere near to a perfect score. Once the cards are dealt, it depends on your skills and understanding of the game whether you can make the most outta bad cards or not.
