In the early 1990s, Gonzalo García-Pelayo won over $1 million at the casino by exploiting a flaw in the roulette wheel.
He used a sophisticated method to predict winning numbers, resulting in a huge win of $624,000 in a single day.
How Gonzalo García-Pelayo cracked the roulette wheel code.
Gonzalo García-Pelayo noticed imperfections in the roulette wheels at Casino Gran Madrid in Spain.
These imperfections led to certain numbers appearing more frequently than others.
García-Pelayo, along with his friends and family, used advanced computer modeling to identify these biased numbers.
García-Pelayo’s strategy led to huge wins and legal trouble
In a single day, García-Pelayo won €600,000 ($624,850).
Over two years, his total earnings exceeded €1 million. However, the casino soon realized what was happening and banned him. A legal battle ensued, lasting 10 years.
Ultimately, the court ruled that García-Pelayo hadn’t cheated, and the casino was forced to allow him back. However, he chose not to return, as he was already too well-known.
Other Gamblers have also exploited flaws in the system
Gonzalo García-Pelayo wasn’t the only one to find a flaw in the roulette system.
Previously, Mechanic Joseph Jagger discovered a bias on certain numbers and won 2 million francs in just a few days.
Similarly, Richard Jarecki noticed a biased wheel in European roulette, leading him to win over $1 million.
Both Jagger and Jarecki were eventually banned from casinos.
Ashley Revell took an extreme route by selling everything he owned and betting his entire life savings on a single roulette spin.
This dramatic approach highlights the unpredictability and excitement surrounding the game of roulette.
Gonzalo García-Pelayo’s clever analysis of roulette wheel imperfections led to major financial gains and legal challenges.
