She Won $17M From Two Casinos. Then Disappeared.

In 2012, a woman walked into two of the most secure casinos in the world and won $17.4 million. She never cheated. She never broke a single rule. And almost nobody knows her name. This is the story of Cheung Yin Sun — known as Kelly — the professional gambler who discovered a flaw in casino playing cards invisible to the naked eye. Using a technique called edge sorting, she turned a 1% house edge into a 6.8% advantage in her favor. Then she used it against the Borgata in Atlantic City and Crockfords in London. Simultaneously. On two continents. It was one of the biggest winning streaks in baccarat history. Phil Ivey brought the fame. Kelly Sun brought the system. Five UK Supreme Court judges ruled against them — but Kelly was never criminally charged. Not in the US. Not in the UK. This is the full story of edge sorting, the legal battles, and the woman behind the biggest casino win nobody talks about. ⏱ CHAPTERS 0:00 — She never broke a single rule 1:00 — A jail cell in Las Vegas 2:00 — The Queen of Sorts 3:30 — The edge sorting method 4:30 — The Borgata operation 7:30 — Crockfords, London 9:00 — The UK Supreme Court 11:00 — The woman nobody knows 12:00 — Next week 🔔 Subscribe for a new loophole every week.
