Patricia Demauro didn’t know how to play craps. She came to the table in Atlantic City with $100. But when the dice came to her, beginner’s luck paid off. The New Jersey grandmother threw, and threw, and threw. Over four hours and 18 minutes, she threw the dice a record 154 times without rolling a seven, Time reports. The odds of doing that? 1 in 1.56 trillion, or 1,500 times less likely than being struck by lightning.
As Demauro’s turn went on, the table became a frenzy of activity, swarmed by spectators and eventually casino personnel. She hit every combination possible that wouldn’t end her roll—some spectators even called out requests, only to see her hit them. “There are all these terms I didn’t know,” Demauro says. She won’t say how much she won. Even average bets would have netted her thousands; expert bets, millions.
