Who Invented Blackjack Card Counting?

In the late 1950s, a group of American math students decided to take on the casinos at their own game. They developed a system of card counting that would allow them to beat the house at blackjack.

The system they came up with is now known as the Hi-Lo system, and it is still used by blackjack players today.

The Hi-Lo system is relatively simple to learn and use. The basic idea is that you keep track of the high and low cards that have been played, and bet more when the deck is in your favor.

PRO TIP:Blackjack card counting was invented by a mathematics professor from the University of California, Edward O. Thorp. He developed his system in the early 1960s and published his findings in the book Beat the Dealer, which became an instant best seller. Thorp’s system works by assigning a numerical value to each card, which allows players to track the ratio of high cards (10s, face cards, and aces) to low cards (2-6) in the remaining deck. The more high cards that remain, the better the odds for the player.

When the deck is stacked with low cards, the odds are against the player, so you bet less. By keeping track of which cards have been played, you can get an idea of what cards are left in the deck, and adjust your bets accordingly.

The Hi-Lo system was developed by a group of American math students in the late 1950s. They used it to beat the casinos at their own game, and it is still used by blackjack players today.

If you want to try your hand at card counting, the Hi-Lo system is a good place to start.
