Ed Thorp: Cracking The Roulette

Advantage gambling has a long history beyond the realms of plays potting. The price bettor of today is the blackjack card counter of yesterday. Indeed, if you determine your spirit on flog a game of chance, you will see opportunities where nobody else assumed they existed. If you come up with your original thought you have a good chance of making a fortune. The narratives of those who did inspire anyone who has gave the goals and targets of shaping the betting groceries. Today I would like to tell you the mesmerizing story of those individuals who cracked the roulette- Ed Thorp.

Ed Thorp Blackjack

If you a regular admirer of this blog, you have already read my clause on Bill Benter and his pony scooting representation. In fact, Bill Benter was inspired by Ed Thorp’s book on blackjack placard counting to become a professional gambler. In a certain sense, Ed Thorp has started a lineage of the sport’s betting greatest. So we could say this article is about where it all began. Let’s see.

Ed Thorp: The life of an advantage gambler

Ed Thorp was born in a low-middle class family. Due to his numerical expertise, he managed to start a promising academic job. After going his physics degree, Thorp was admitted to a PhD in math from UCLA( University of California, Los Angeles ), which he graduated in 1958. Reportedly, this is where his academic interest in gambling started to grow. After his graduation, Thorp has worked as a professor in MIT, New Mexico State University and University of California, Irvine.

From maths to Blackjack

In the meantime, Thorp developed his theories in plays of probability further. Even though Thorp was pursuing an academic job, he was not afraid to apply his theories in practice. His most notable research( and the one that would later on grant him a widespread recognition) was in the field of blackjack. Thorp developed a prevail card-counting intrigue and in association with pro-gambler and striking undeground digit Manny Kimmel, obligated his first benefits in Vegas casinos.

Ed Thorp's 10 Count System

The card check system of Ed Thorp took advantage of the fact that casinos were not reshuffling the floor before it was dealt to the end. Observing the cards leaving the deck, the relatively simple system calculated the chances to be dealt a good poster from what is left.

Ed Thorp managed to prove that information systems use in practice as well as in theory. His discovery motivated him to write the best selling book Beat the Dealer, which laid down his method in detail. This was the first blackjack card-counting system made available to the general public. The bible informed the first contemporary of smart-alecky punters, that would use their recently learned system to try and beat the casino, among which was the most William Benter.

Unfortunately the system in itself is insufficient to beat the casino nowadays. Today, casinoes shuffle placards style before the end of the deck. Nonetheless, it has been the basis for some most complicated blackjack card-counting systems to follow. Thorp’s contribution to the field of blackjack made him a home in the Blackjack Hall of Fame

Stepping it up- association with Claude Shannon

Ed Thorp was starting to feel the flavor of success, but his biggest hit was yet to come. Directing his act away from shady illegal bookmakers and towards some of the brightest brains he encountered in his tenure as a math prof, Thorp started working with Claude Shannon to find brand-new margins on the gamble market.

Who is Claude Shannon

Claude Shannon associate of Ed Thorp

Claude Shannon was an early associate of John Kelly( yes, that Kelly) in Bell Labs. The two work in partnership in the field of game theory and were well aware of each others work. This would lead to Shannon being among the first to recognize the potential of the Kelly criterion and apply it successfully to gamble and investing.

Shannon became famed for his research in the field of combined application of electricity and algebra to solve numerical difficulties, which gave him the name “the papa of information theory”. It is safe to say that Shannon laid the foundation for the discovery of the modern computer.

And what else would the father-god of information theory do in his spare time, than find ways to crack the roulette.

Ed Thorp and Claude Shannon’s joint venture: Cracking the Roulette

It was known at the time that it is impossible to beat a balanced roulette. In its most popular format, the roulette has 36 red and pitch-black parts. Those are offering a 1/36 chance to pay you 36 hours your stake, for an expected value of zero each. Then comes the dark-green 0, which doesn’t win you anything and represents the house edge( and negative expected value for the operator from the game) of 1/37 or around 2.7%. Pretty simple and awfully random activity known to be EV- is what the roulette was at the time.

But was it certainly that random?

The question Throp and Shannon asked themselves was, is the roulette genuinely random? After careful watching they have noticed some motifs of behaviour from the merchants, who were rolling the wheel.

In order for a casino to maximize its benefit, the roulette must go as many times as possible. This puts pressure on the merchant to run the motor as quickly as he can. A good dealer would therefore be one that can learn to do the turns as seamlessly and automatically as possible. It is a skill that is acquired in time and the experienced traders in Vegas casinos seemed to have it.

However, what this learned automation leads to, was that a peddler would( unknowingly to himself) tend to roll the rotation exactly a certain amount of seasons every time he goes. A novice marketer would realise, say, 27 to 31 buns of the rotation. An known one, on the other hand would remain between 28 3/4 and 29 1/4.

The edge this finding could furnish was massive. Restricting the possible number of outcomes by half could awfully increase the EV of the gambler. He simply needed to identify in which area of the pedal the dance was expected to land. To find this out was a difficult problem. But not so much better for Thorp and Shannon.

The first wearable computer

Chances are you already have ascertained one of the following options 😛 TAGEND

The iWatch is the Apple model of a smartwatch, a.k.a. a wearable computer. Those things are quite popular nowadays. Their utilizations include quantifying your heart rate while doing athletics, checking the weather or making a phone call. But they were actually invented for lottery by, you approximated it, Ed Thorp and Claude Shannon. In other statements , none of those illusion devices that millions of parties are wearing today wouldn’t have existed, if not for those two smart mortals spending months sitting and thinking of ways to make some coin on the roulette in Vegas. Remember that for the next time someone tells you gambling is immoral or a zero-sum game.

The two have tested the prototype of the first wearable computer in Shannon’s home basement in 1961. After the tests were successful, they have settled it to good use in a number of casinos. The computer was counting the revolutions of the rotate and displaced the results via an electrical signal. It then converted the signal into a sound played into the player’s ear, in what was an early form of a micro earpiece. Granted, the whole thing was a bit bulky and nothing that you can sell in an iStore nowadays. But it did the drive, allowing its wearer to sit a roulette wager with an estimated 44% rim over the house.

A money-printing machine?

The edge was indeed massive and there was enough unassuming casinoes around there willing to make the action. This is not to say the scheme didn’t have its weak spots. For example, the connection to the earpiece was justification a good deal of hassle. Therefore, it had to be fixed live every now and then, as Thorp recollections. Nevertheless, partly as a result of Thorp and Shannon’s invention, the position of Nevada boycotted the purpose of applying wearable devices in casinoes later in 1985.

Today, the wearable computer is part of the exhibition of the MIT Museum in Cambridge, Mass.

What came next?

It swiftly has become evident that for a thought of the caliber of Thorp, sharp-witted gamble is too small of a playing field. Thorp exercised his earned capital and numerical revelations in the financial market, which has all along been gave him hundreds of millions of dollars. Nonetheless, he will ever have a special place in hearts and judgments of the lottery community due to his contributions to the field. Thorp’s work inspired the first generation of smart-alecky speculators, who would employ numerical and statistical models and use the assistance of electronic inventions to triumph in games of chance.

From there on, the computer model of Bill Benter that outstrip the racetrack was only a matter of time and, of course, attaining the title lover for the job. Until now, when different sorts of sophisticated algorithms are being applied en masse to predict the outcome of a boast occurrence and trounce the betting busines. It was a mesmerizing increase, that opened great opportunities in front of mathematically endowed parties, but likewise endlessly shrunken the playing field for everyone else. We shall ensure what the future creates in that regard.

Ed Thorp on the web

If you would like to dive deeper into Throp’s life story you can check his biography. It lays out the details around his inventions and includes many interesting anecdotes. Furthermore, on Mr. Thorp’s website, you can find, among other things, a lot of huge free articles on the topics of finance and gambling written by him, where you can learn a thing or two about his methods.

Finally, The Investor’s Podcast has done an interrogation with Ed Thorp, where you could hear the man speak 😛 TAGEND

As is obvious from the name of the podcast, the chapter revolves more around finance. I find it an interesting piece nevertheless.


This was my report on the fascinating storey of Ed Thorp and his gamble success. Being perhaps the first foremost advantage adventurer, Ed Thorp contributed tremendously to the fields of blackjack, roulette and activities of likelihood in general. Furthermore, he was ready to share clods of his lore along the way by writing bestselling journals and regularly appearing in the public via interviews or his own writings. In that route, he paved the space for numerous future bet tales such as Bill Benter, Zeljko Ranogajec, Tony Bloom and others.

The road to success is long and hard, but I hope Ed Thorp’s floor "ve given you" some inspiration to continue on your betting passage and perhaps a few ideas to work on. Next in line I have a few articles in sentiment about live wager, the latest developments in my LoL model and some interesting bet tools. If you subscribe to my Twitter channel and my newsletter on the upper-right corner of your screen, you will make sure not to miss any of these. I hope you enjoyed the article and see you around!
