Who is the gambler who cracked roulette?

Hi mrBean,😉

The legendary gambler who famously cracked the game of roulette was Joseph Jagger.

In the 1870s, Jagger made a detailed study of the roulette wheels at the Beaux-Arts Casino in Monte Carlo. 

By carefully observing the wheels over an extended period, he was able to detect a subtle bias in one of them - the ball was more likely to land in certain sectors than others.

Jagger started betting heavily on the biased numbers on that particular wheel. Over the course of a few days, he managed to win over $70,000, an absolute fortune at the time.

Casino officials eventually realized there was a defect in the wheel that caused the bias. They swapped out the wheel, and Jagger's winning streak came to an end. 

But his exploits made him a legend among gamblers and earned him the nickname "The Man Who Broke the Bank at Monte Carlo."

Jagger's clever use of observation, perseverance, and deductive reasoning to overcome the casino's statistical advantage became a celebrated example of a gambler beating the house at its own game. 

His exploits helped cement roulette's reputation as a game where a few outliers could find an edge despite seemingly overwhelming odds.

Hope that helps!🤗
