In the world of gambling and casino games, few names command as much respect and admiration as that of Edward O. Thorp. A mathematician, professor, hedge fund manager, and professional blackjack player, Thorp’s revolutionary work on card counting changed the landscape of casino gaming forever. In this article, we delve into his incredible life story and accomplishments, and how he became the mastermind who established new strategies to beat the house in blackjack.

The Early Years of Edward O. Thorp

Born on August 14, 1932, in Chicago, Illinois, Edward Oakley Thorp demonstrated a strong aptitude for mathematics from an early age. He went on to earn a Bachelor’s Degree in physics and a Master’s Degree in mathematics before obtaining his Ph.D. in mathematics from UCLA in 1958. It was during these formative years that Thorp developed his keen interest in probability theory and its applications; little did he know that this fascination would lead him to revolutionize one of the most popular casino games – blackjack.

Discovering Card Counting

Thorp’s initial insight into card counting began while studying the mathematics of casino games for a lecture at MIT. During his research, he stumbled across an academic paper published by mathematicians Roger Baldwin, Wilbert Cantey, Herbert Maisel, and James McDermott in 1956. This paper revealed that blackjack, unlike most other casino games, is not purely based on chance but rather subject to changing probabilities.

Intrigued by this finding, Thorp delved deeper and discovered that if certain cards had been played, a player could have a greater success rate or an increased likelihood of winning. For additional hints, he began to develop and refine his own card counting method, testing it in casinos and honing it through mathematical analysis. It wasn’t long before Thorp’s groundbreaking work caught the attention of gambling enthusiasts and casino owners alike.

Beat the Dealer: The Book That Changed Blackjack Forever


In 1962, Edward O. Thorp published his findings in a book called “Beat the Dealer.” He detailed his revolutionary card counting technique, known as the “Ten-Count System,” which involved keeping track of the number of ten-point cards (10s, Jacks, Queens, Kings) that had been played within a game of blackjack. When there was a higher proportion of these ten-point cards left in the deck, the odds would shift in favor of the player. You can now find various books and resources on card counting, building upon Thorp’s original strategy.

“Beat the Dealer” immediately became a bestseller and sent shockwaves through the gambling world. Amateurs and professionals alike began using Thorp’s techniques to improve their chances, resulting in huge profits for skilled blackjack players and significant losses for casinos unprepared for this new approach. As a response, many casinos altered their rules and implemented countermeasures designed to thwart card counters. However, public outcry led most casinos to revert to traditional rules, essentially admitting they could not completely counteract skilled card counters like Thorp and those who followed his teachings.

The Lesser-Known Roulette Revolution

While card counting was undoubtedly Thorp’s most famous contribution to the world of gambling, it wasn’t his only one: he also worked with fellow mathematics professor Claude Shannon to develop what came to be known as the “Thorp-Shannon Roulette Prediction Device” in the late 1960s. This wearable computer was designed to predict the outcome of roulette based on several factors impacting a ball’s trajectory, such as the speed of the wheel and the ball’s initial position.

Though the device never saw widespread adoption or success, it embodied Thorp’s deep-seated belief that probabilistic analysis and information theory could be applied to seemingly random processes. His contributions to the fields of mathematics and probability theory not only revolutionized gambling strategies but laid the groundwork for today’s sophisticated predictive models and algorithms used in various industries.

The Impact of Edward O. Thorp on Today’s Gambling Landscape

Edward O. Thorp’s revolutionary approaches to both blackjack and roulette have had a profound and lasting impact on the world of gambling, showing players they can improve their odds with cunning strategy and smart decision-making. In fact, many casinos now employ advanced surveillance systems that closely monitor players for signs of card counting techniques to protect themselves against skilled players who could make use of the methods first developed by Thorp.

The Rise of Online Blackjack

In recent years, online casinos have gained in popularity, appealing to those seeking a convenient way to enjoy their favorite casino games from the comfort of their homes. This shift to online platforms has also been influenced by Thorp’s legacy, as many knew they could learn and incorporate card counting strategies into their own play. One trusted online platform is Betiton, where players can partake in blackjack online— even for free — and test their skills using Thorp-inspired strategies.

Wrapping up

The brilliance of mathematician Edward O. Thorp is undoubtedly impressive, having helped push the boundaries of gambling strategy through his work on card counting and roulette prediction devices. Thorp demonstrated that understanding the underlying probabilities and cleverly developing strategies based on those probabilities could give players an edge in the world of casino gaming, forever changing how we approach games like blackjack.
