The Hi-Lo (High Low) system is one of the easier and more popular card counting systems for blackjack. The Hi-Low consists of assigning a point value of +1, 0, or -1 to every card dealt to the player. Each card is assigned a specific point value in the Hi Lo System. Aces and 10-point cards are assigned a value of -1. Cards 7, 8, 9 each count as 0. Cards 2, 3, 4, 5, and 6 each count as +1.
If player 1 is dealt a 3 and 9 (+1, 0), player 2 has a 10 and a 5 (-1, +1), player 3 has a 7 and a 2 (0, +1), and the dealer’s upcard is an Ace (-1), the running count in a single deck would be +1. That’s not too bad, right?
All a counter using the Hi-Lo System must do is add and subtract by 1 and keep a true count of the deck. Try to look at a two cards at once and figure out the combined count so you aren’t tallying every single card. Also, a good card counter will sit at 3rd base (last position to be dealt at the table) so he/she can easily see the cards being dealt. This is a very simple system but if you play it right, you can get great results.
