The Mathematician Who Won the Lottery 14 Times

Mandel was a Romanian-born economist who, in the 1960s, was living under Communist rule on a tiny salary. He wanted out, and he wanted serious money to do it. Instead of turning to crime, as he later said many around him did, he turned to mathematics. After years of studying probability, he developed an approach he called "combinatorial condensation" — and his first lottery win helped him eventually move his family to Australia.

Mandel's core insight was simple to state and hard to execute. Every lottery has a fixed number of possible number combinations. If you could buy a ticket for every single combination, you would be guaranteed to hold the winning ticket.

That only makes financial sense under one condition: the jackpot has to be larger than the cost of buying every combination. Mandel waited for exactly those moments — when a jackpot grew so large it was worth more than the price of covering all the numbers.

After a string of wins in Australia, Mandel turned to the United States. He targeted the Virginia state lottery because it used numbers 1 to 44 — meaning there were 7,059,052 possible combinations, far fewer than most lotteries. In February 1992, with the jackpot above $27 million, his syndicate raced to buy tickets across the state.

It did not go perfectly. Some retailers backed out, and his team managed to buy only about 6.4 million of the roughly 7 million combinations. They got lucky that the winning combination was among the ones they bought. The syndicate took the jackpot, plus around $900,000 in smaller secondary prizes.

Mandel's strategy was pure mathematics. His office combined chalkboard combinatorics with cutting-edge 1980s computing.

An operation that buys millions of lottery tickets draws attention. Mandel and his fund were investigated by US authorities, reportedly including the FBI and CIA. Their conclusion: he had broken no laws. He had simply understood the mathematics and logistics better than anyone else.

But lottery operators did not want a repeat. Rules were changed — in Australia, the US, and elsewhere — to ban bulk ticket buying and the use of computer-printed tickets. The loophole Mandel exploited was deliberately closed.

The popular version of this story stops at "won 14 times." The fuller version is more complicated. Mandel's investors, according to reporting on the syndicate, often received fairly modest payouts. Mandel himself declared bankruptcy in 1995, just a few years after the Virginia win. He later retired to the Pacific island of Vanuatu.

Mandel's tale is genuinely impressive — but it is not a strategy guide. He never predicted numbers; he bought every combination, which is a completely different thing. It only worked when a jackpot exceeded the cost of all combinations — a rare situation. It required huge upfront money, investors, and enormous logistical effort. And it is no longer legal.

For a regular player buying a few tickets, there is no version of Mandel's method to apply. The math that made him famous is the same math that makes the lottery a long shot for everyone else.
