Compared to many other casino table games, the blackjack house edge appears to be much lower. In fact, in a regular game it hovers at around 2%. Because blackjack is a game of both luck and skill, it's quite possible, that by playing perfect blackjack strategies, you can lower this down to around 0.5%. Only by using card counting can you get to this amazing figure. But the truth of the matter is that the counting of cards is very difficult at a land-based casino, and impossible online.
