Joseph Jagger, the First World-Famous Roulette Player

Joseph Jagger, famous roulette player

The person discussed in this article can not be considered a cheater. He did not break the casino rules but skillfully used blunders in the game and won considerably. We are talking about defects in the roulette wheel he managed to find.

Who Was Joseph Jagger?

Joseph Hobson Jagger's name is written into the history of the gaming world as a person who won at roulette in the Monte Carlo casino. He lived from 1830 to 1892; for that time, these achievements seemed incredible, but the stories about him have many existing eyewitnesses to be sure about their reality. However, there are also many questionable stories about his personality.

For example, you can find versions that he was the ancestor of the famous rock musician Mick Jagger of the Rolling Stones.

Joseph was a British engineer who worked in the cotton industry in Yorkshire. He was one of the first to discover that the mechanical tape results were not completely random because the device was not perfect. To test his observations, he hired six assistants who secretly recorded winning numbers in the roulette at the Monte Carlo casino.

Carefully examining the results, he discovered that one of the roulette wheels demonstrated bias in its work. This was expressed in the fact that nine of the winning numbers were much more common than the others.

Starting a Career as an Advantage Gambler

With that knowledge, Jagger went to the casino on July 7, 1875, and won about fourteen thousand pounds.

In today's money (considering the difference in prices and inflation) it is about seven hundred thousand dollars! He continued to play for three days, winning sixty thousand pounds.

Even other players realized that they should follow his example and started to bet on the same numbers as he did.

Ultimately, the casino discovered what was happening, and the roulette wheels were changed to confuse Joseph. At first, he was bewildered, but his wonderful memory helped him. He remembered a scratch on the wheel and found it in another part of the hall. The rest was a matter of technique, and Jagger won considerably.

The casino decided to act more subtly.

  • It replaced metal parts and spacer bumpers on the roulette wheel. The wheel's balance changed, and spots that often won became less " lucky."
  • Moreover, they did it every day during the technical break. This way, they wanted to return the money Joseph won.

And it was partially successful. Jagger fought with a tape for two days, constantly losing, and then realized he could no longer win here.

Nevertheless, the money he lost was much less than his previous winnings. He left Monte Carlo with an amount equivalent to today's three million dollars and was never seen again. Joseph left his last job and was quite rich, not to play anymore but to invest money in real estate.

The story quickly spread around the world and forced casinos to pay more attention to roulette's technical condition. At least, no one could repeat that in Monte Carlo.


Roulettes in Contemporary Casinos

Modern roulettes from well-known manufacturers work perfectly, but in some casinos, you can still find worn wheels made by questionable companies or expensive models with defects.

This practice is impossible in online casinos because a random number generator determines the winning numbers. In respectable casinos, the operation of RNG is tested by independent regulatory agencies, and the results of these audits are published on the casino site.
