Joan Ginther achieved a remarkable feat by winning the lottery four times, amassing millions and earning the title of one of the luckiest individuals ever.
Consider all the times you’ve purchased a lottery ticket without a win—it’s a familiar disappointment for many.
Joan Ginther, however, was a stranger to such disappointment, securing a total of $20.4 million across four lottery victories from 1993 to 2010.
This incredible streak sounds almost implausible, but a statistician believes they have found the key to her success.
Ginther was no ordinary lottery participant. With a PhD from Stanford and a background in teaching college mathematics in California, she possessed a sophisticated grasp of probability and odds.
Her winning journey began with $5.4 million in 1993, continued with $2 million in 2006, $3 million in 2008, and peaked at $10 million in 2010.

In an interview with the Daily Mail, a statistician offered insights into how Ginther may have orchestrated her lottery success.
Alan Salzberg, a senior statistician at Salt Hill Consulting, suggested that her mathematical expertise was not the sole factor behind her wins.
Unfortunately, there’s no simple method to replicate her success, so aspiring lottery winners may be out of luck.
He remarked: “The math of lotteries isn’t that hard. I don’t think you need a Ph.D.
“I doubt it was the hand of God here, and I doubt she spent a tiny amount of money to get these winnings.
“It’s somewhere in between. She probably figured out a little bit and she also probably spent a lot of money to win these.”
Salzberg speculated that Ginther reinvested some of her winnings into the lottery, playing frequently enough to boost her chances, especially in games with favorable odds.

The statistician theorized that Ginther may have focused on lotteries with better odds and potentially gained an advantage by living in rural areas, where fewer people participate, and jackpots don’t attract as many players.
On April 13, 2024, Ginther passed away at 77, with natural causes related to cardiovascular disease believed to be the reason.
In her passing, she was remembered for leading a discreet life and sharing her wealth generously with children, friends, and family.
