In any casino game, the house will always have an edge. But Blackjack is one of the games where the house retains a much lower edge than in case of the other casino games. Therefore, it is much easier to win at Blackjack if you have good skills to play the game. If you are good at card counting, you have a distinct advantage, though the casinos do not favor it at all. While playing blackjack if the casino even suspects you of card counting, you might be asked to leave the place.

Since card counting in Blackjack is becoming more and more common these days, the casinos are trying newer strategies to clamp down on card counters. In order to confuse the card counters, the casinos add more decks of cards to the dealing shoe rather than deal from a single deck. Some have introduced reshuffling of the cards mid-way. This is an effective method adopted by casinos to make things difficult for the blackjack player who indulges in card counting.
