Has someone used MATHS to get rich?

Meet Joan Ginther, famously called “the luckiest teacher in the world.” She didn’t just win the lottery once or twice—she won it four times. In 1993, she took home $5.4 million. In 2006, another $2 million. Then came $3 million in 2008, and finally a staggering $10 million in 2010. Altogether, that’s over $20 million in winnings.

But here’s where things get intriguing: Joan wasn’t your average lottery player. She holds a PhD in Statistics from Stanford University, which immediately raised eyebrows. From her home in Las Vegas, she would travel all the way to a small rural store in Texas to buy her tickets—every time from the same location. Coincidence? Some people doubt it.

Journalist Peter Murca from Philly.com investigated her story and suggested that Joan’s wins may not have been just luck. Her first win, he believed, was pure chance. But the next three? Possibly the result of strategic brilliance.
He theorized that Joan could have used her deep understanding of probability and logistics to tilt the odds in her favor—perhaps by tracking which stores received which ticket batches, monitoring unclaimed prizes, or even spending millions of dollars buying tickets where she knew the odds were slightly higher. Others even speculated there might have been an inside connection, though nothing was ever proven.

To this day, no one knows for sure. There’s no hard evidence that Joan gamed the system. Maybe she cracked a statistical pattern no one else saw—or maybe she was simply one in a billion.

Either way, her story remains one of the most fascinating mysteries in lottery history. Was it math? Was it luck? Or was it something in between?

One thing’s for sure: Joan Ginther didn’t just play the odds—she might have rewritten them.
