text_A: In the early 1990s, Gonzalo Garcia-Pelayo believed that casino roulette wheels were not perfectly random, and that by recording the results and analysing them with a computer, he could gain an edge on the house by predicting that certain numbers were more likely to occur next than the 1-in-36 odds offered by the house suggested. This he did at the Casino de Madrid in Madrid, Spain, winning 600,000 euros in a single day, and one million euros in total. The casino succeeded in legally banning him from any future roulette games due to his unfair advantage after the casino proved to the court that a physical wheel can never be made perfectly random.
text_B: Regardless of who technically won the lawsuit, does it sound like Garcia-Pelayo's dedicated efforts paid off for him, monetarily?
YES.
