The famous Casino de Monte-Carlo in Monaco briefly banned roulette in the 19th century due to a string of extraordinary wins by Charles Wells. In 1891, Wells managed to break the bank by winning an unprecedented amount over several roulette sessions, causing the casino to temporarily suspend the game. The massive winnings led to concerns about the integrity and financial stability of the casino, prompting the decision to halt roulette. However, the ban was short-lived, and roulette was eventually reinstated, continuing to be a staple of casino gaming.
