Card counting is obsessed by many experienced players, as it enables them to stay in the game and beat the house. In a land-based casino, the dealer is required to keep a running count of the cards to determine whether the player has won or not. The house edge in this type of casino is about 0.35%, which is much higher than the usual stake.
Card counting is therefore illegal in most of the casinos. In Las Vegas however, card counting is legal, as the casinos have an incentive to make the payouts more attractive. There is however one Las Vegas casino where counting is allowed – the Luxor casino.
Although you won’t be able to card count in normal blackjack games, certain blackjack card counting systems, such as the Hi-Lo card counting system, which is also used in the game of Puerto Rico, can be applied. There are also other card counting systems, such as the balanced-risk card counting system. These systems aim to go beyond simply keeping the count, and actually will adjust the play in such a way that the cards will fall into a certain range, adding to the players advantage and making it easier to predict the value of the cards.
In blackjack card counting there is a division between the value of the cards, and their likelihood of being dealt. cards 2-6 have the highest value, 7-9 have medium value, and 10-A have the lowest value. The cards 10, Ace and King are counted as zero, and the rest of the cards are counted on a value of their own. The Hi-Lo card counting system is one of the popular card counting systems, which was discovered to be very effective when applied to blackjack games by a group of MIT students.
In blackjack card counting, cards are given a value (-2, -1, 0, +1, +2) in the clear in a sequence of their arrival, starting from the top of the deck and descending. The -2 value cards are given the earliest, the +1 cards the latest.
Card counting seeks to take advantage of the fact that the cards are dealt from the top of the deck, and neglects the fact that the cards 7-9 are viewed as being less significant than the cards 3-6. According to blackjack card counting, as cards 4-6 are “due” for distribution to the players, their absence from the deck increases the probability of the card 7-10 being dealt sooner.

Because tens are the most common card in blackjack (and because 4-5-7 are the most common card in the deck), their presence in the deck provides a greater advantage to the player. In blackjack card counting, it is also important to track the cards that have already been dealt and those, which are still live, as these cards are signs of upcoming high cards, or low cards, which will allow a better assessment of their likely value when the deck contains a third of their face value.
Because tens are the most common card in blackjack, their absence from the deck provides a greater advantage to the player, as a higher likelihood of receiving a higher card in upcoming hands. In addition, as the number of tens in the deck is relatively high, you will experience a greater likelihood of receiving a card of a particular value, such as 10 or 11, when those cards are still live.
By keeping a close eye on the cards being dealt, and making a note of those cards with high values (4, 5, 6, or 7) you can efficiently increase your odds of receiving a card of a particular value or a card of a higher value (10, J, Q, K, or A).
