It's better to start with card value chart at once and then pass on to explanations.

As we see in the chart given below there are 3 basic groups of cards according to their value and count as a result. In Hi-Lo card counting system we observe five small cards value 2, 3, 4, 5 and 6 and counted as +1 while playing. This type cards sum is 20 in whole.

Also we see 7, 8 and 9 which a taken as a middle cards (12 in the deck). They are considered as neutral and don't influence the count total.

The 20 big cards (10, J, Q, K, A) are counted as -1 while playing.

It must be mentioned that the Hi-Lo system is a balanced one. That means when you end to count all the 52-card deck you get 0 as a final counting point.


For better understanding how the system actually works we offer you to observe the following imitating example.

Imagine 3 players and 1 dealer at the playing table.

The dealer keeps in mind the blackjack rules and thus distributes 2 cards for each player and one face-up card for himself.

E.g. Mr. Wise has 4 + Jack, Mr. White has King + 7, Mr. Black has 10 + 2 and the dealer has Queen as a hole card.

This is the first round of the game and thus Mr. Wise starts to count with 0 and begin with his own cards. He adds 1 to initial 0, then minuses 1 (4 + Jack). After that he minuses 1 and adds nothing (King + 7) and again minuses 1 and this time adds 1.

The player initial hands total gives Mr. Wise -1 count to which he minuses another 1 as the dealer has Queen.

As a result for this very moment of the game the count is -2. Mr. Wise keeps it in mind and proceeds with his playing and counting.
