# Blackjack Card Counting Systems

Blackjack, or Twenty-one, is the most popular casino game.[1] With the development of the personal computer, players, including mathematically skilled individuals who had used brute force methods to develop systems to win at the game, found that computer-developed systems provided a distinct advantage.

In the 1960's, blackjack became the most popular of casino games after computer-based systems were developed which gave an edge to the player. Various mathematicians and gamblers including Edward Thorp and Les Golden have refined these systems.[2][3][4][5][6]

The following table summarizes the most popular and most powerful systems. References are provided to the developers of the systems and the most authoritative websites which discuss their attributes.

The numbers in the table are the values assigned to the given card. In blackjack, 10s, Jacks, Queens, and Kings are all considered "10-value" cards. The total "count" of a hand is the arithmetic sum of the values assigned to the cards being held in the hand.
