Richard Wilhelm Jarecki (December 1, 1931 – July 25, 2018) was a German-born American physician who won more than $1 million from a string of European casinos after cracking a pattern in roulette wheels.
[1] He married Carol Fuhse, a nursing student at Jersey Shore Medical Center, while he was completing his residency there.
[1] In the 1960s and 1970s, Jarecki started visiting casinos across Europe and began working with his wife Carol and others to keep track of tens of thousands of spins of roulette wheels, often over the course of a month.
After analyzing the results, Jarecki was able to determine that some wheels had a subtle bias that made it more likely to land on certain numbers due to imperfections and wear, though he created a cover story that he had used a computer at the University of London to crack the games.
After winning more than $1.2 million using his technique, he returned to the United States in the mid-1970s to become a commodities trader trading in gold and silver, as well as dabbling in blackjack and roulette in casinos in Atlantic City, New Jersey and Las Vegas.
