Stefan Mandel, a Romanian mathematician, pulled off a feat that sounds impossible: he won 14 lottery jackpots across three countries by buying every single number combination. His biggest hit came on February 15, 1992, when he and a network of investors claimed a $27 million Virginia jackpot. The strategy worked so well that regulators in Australia and France rewrote their rules to stop anyone from repeating it.
The Math Behind the Tickets
Mandel didn't hack the system or find a loophole. He exploited basic probability. In a lottery with a finite pool of numbers, buying every possible combination guarantees a win — but only if the jackpot exceeds the cost of buying all those tickets. That's the tricky part: the number of combos can run into the millions, and the upfront cost is huge. Mandel figured out how to make it work by recruiting a network of investors willing to front the cash. He used computers to generate all the combos and printed tickets by the thousands.
How the Virginia Win Happened
The $27 million jackpot in Virginia came from the 'Lotto 6/44' game, which had 7,059,052 possible number combinations. At $1 a ticket, buying every combo would cost over $7 million — well below the jackpot, but still a massive sum. Mandel's investor group pooled resources, set up a warehouse of printers and computers, and spent weeks preparing. On draw day, they submitted millions of tickets just hours before the deadline. Their strategy paid off: they held the sole winning ticket, netting $27 million. After taxes and payouts to investors, Mandel's share was still a life-changing amount.
Regulators Step In
Lottery officials in Australia and France weren't amused. After Mandel's earlier wins in Australia in the 1990s, regulators there amended their rules to forbid the systematic purchase of all combinations. France followed suit. The changes made it illegal — or at least impossible in practice — to replicate the bulk-buy tactic. Virginia didn't change its rules immediately, but other states tightened restrictions later. The strategy still works on paper, but today's lotteries often cap ticket sales per person or limit bulk purchases, making Mandel's method a relic.
Mandel himself eventually moved to the United States, but his lottery-buying days ended. He once said in an interview that the hardest part wasn't the math — it was the logistics of printing and organizing millions of tickets under tight deadlines. Regulators made sure no one else would have to try.
The question that lingers: are there any lotteries left where the numbers still line up? With modern rules and ticket limits, probably not. But Mandel's 14 jackpots stand as a monument to what happens when pure math meets a system that wasn't built to handle it.
