1. Ashley Revell: The Man Who Bet His Entire Life on Roulette

📍 Location: Plaza Hotel & Casino, Las Vegas, United States
📅 Date: 11 April 2004

Ashley Revell, a British gambling enthusiast, made a completely insane decision: to sell absolutely all his belongings, including his car, his clothes, and even his sports equipment, to turn his entire fortune into a single bet on roulette. In total, he raised $135,300 and headed to Las Vegas to attempt the unthinkable.

At the Plaza Hotel casino, under the cameras of a television show (Double or Nothing), he placed everything on red. A heavy silence set in... the ball spun... and landed on red 7! Revell doubled his money and left the casino with $270,600.

But the casino informed her that the win was a "technical error" and that the machine should never have displayed that amount. As compensation, they offered her… a free steak and $2.25 (the supposed correct payout).

• Furious, she sued the casino, but the court ruled against her, as slot machines have clauses stating that errors do not result in actual winnings. A bitter end to a shattered dream…

She played for 4 hours and 18 minutes, attracting a fascinated crowd. Finally, she decided to stop before losing.

• Outcome: She refused to reveal how much she had won, but some experts estimate that her achievement earned her hundreds of thousands of dollars. Her record remains unbeaten to this day.

📍 Location: Las Vegas, United States
📅 Period: 1980s-1990s

Richard Marcus, a former dealer turned professional cheater, invented one of the most ingenious schemes to scam casinos.

His trick: the "Savannah Move." He would bet three stacked chips: two small ones ($5 each) on top and a large one ($500) hidden underneath.

• If the bet lost, he discreetly removed the $500 chip, reducing his loss to just $10.
• If the bet won, he left the stack as it was, pocketing a huge win.

With this simple but effective technique, Marcus stole hundreds of thousands of dollars before casinos caught on. When he was discovered, he admitted to his exploits and became a casino security consultant.

His story has inspired several books and films about gambling and casino cheating.
