The Spanish Pelayos family renewed the experience of Joseph Jagger. In the years 90. Gonzalo pelayo, from Madrid, believes that roulettes are not perfect machines and therefore there is a way to reverse the casino advantage. To verify his hypothesis, he starts to observe the roulettes of a casino in Madrid and quickly notices that some numbers come out more than others, but to have exploitable results, he must establish statistics for each number on more than 5000 prints (see attached documents).
To help him in this endeavor, Gonzalo Pelayo then calls on his family, they put a large network in place and each roulette wheel is scrupulously examined. The process takes two weeks, from the opening to the closing of the casinos.
The results showed that indeed none of the casters were perfect and that on each one some numbers came out more often. Then came the time to play, and it was a great success. A little after, the Madrid casino closed its doors in Los Pelayos (last names match in Spanish). No matter, for the Pelayos, it was a revelation and baited by this easy money they repeated the experience, breaking the banks of casinos around the world: Vienna, Copenhagen, London, and Vegas Las Vegas. In reaction, casinos have sued members of this family, questioning the legality of their method. Following a trial that lasted almost 10 years justice ruled in favor of Pelayos, who therefore keep their earnings to the tune of approximately 1.5 million de dollars.
Moreover, the family published a book telling their extraordinary story, The Fabulous History of Los Pelayos sold over 20,000 copies and the book is said to be cinematically adapted.
