Stefan Mandel explains the “simple math” that allowed him to win the lottery 14 times, including a detailed strategy he used to increase his chances of winning. Discover how he beat the odds and what the government did to stop him.
Winning the lottery is often seen as a game of pure luck, but for Stefan Mandel, it was a matter of “simple math.” Mandel, who has won the lottery an astounding 14 times, used a unique strategy to significantly increase his chances of hitting the jackpot.
The odds of winning the Mega Millions jackpot are a staggering 1 in 302.5 million, making it seem nearly impossible for anyone to win such a massive fortune. However, Stefan Mandel defied the odds and cracked the lottery code, making him a living example of how persistence and mathematics can change the game.
The Strategy Behind Mandel’s Success

Mandel’s approach was based on a theory he called “combinatorial condensation,” which involved pooling money together with a group of people to buy enough lottery tickets to cover every possible combination. This method allowed the group to increase their chances of winning, and it proved to be successful time and time again.
His first big win came when the group won $19,000, which left Mandel with just under $4,000—enough for him to move his family from Romania to Australia. Over the years, Mandel’s syndicate, known as the International Lotto Fund (ILF), went on to win the lottery a total of 14 times. While they didn’t always hit the jackpot, they still secured significant amounts of money in various countries, including the US, Australia, and Romania.
The Legal Struggles and Lottery Rule Changes
While Mandel’s method wasn’t technically illegal, it raised a lot of suspicion among authorities. The CIA and FBI even investigated him and the ILF for potential wrongdoing, though they were ultimately cleared of any criminal activity.

Despite his legal victory, Mandel’s journey wasn’t without its challenges. In 1995, just three years after winning a $27 million jackpot, Mandel declared bankruptcy. He spent the next decade running several investment schemes, facing financial difficulties along the way.
His “combinatorial condensation” algorithm, which allowed him to purchase enough tickets to play every possible combination, caused so much disruption that the US government stepped in. Laws were changed to prevent players from buying bulk tickets or using computer-generated ones, effectively making Mandel’s method impossible to replicate.
What’s Next for Lottery Players?
If you were hoping to test your luck using Mandel’s strategy, it’s no longer possible. The rules have been adjusted to ensure no one else can repeat his success. But Mandel’s story remains a fascinating tale of how mathematics and perseverance can sometimes defy the odds.
