LotteryThere's a real, well-documented mathematician who won lottery jackpots 14 times — and the method wasn't a secret formula, a hidden pattern, or luck. It was a straightforward, legal rule anyone could calculate with basic combinatorics: buy literally every possible number combination, but only when the jackpot makes it worth the cost.
The Basic Idea, and Why It Actually Works
If a jackpot is $1 tickets and there are, say, 3.8 million possible combinations, buying one ticket of every combination costs $3.8 million and guarantees matching the jackpot — there's no possible outcome where none of your tickets wins. The catch is obvious: if the jackpot itself is smaller than what it costs to cover every combination, you'd be guaranteed to lose money even while guaranteeing a win. Mandel's actual insight was numerical: he wouldn't act unless a jackpot had grown to roughly three times the cost of buying every combination, which left enough margin to cover printing, logistics, investor payouts, and taxes and still come out ahead. As he put it himself, "any high school math student could calculate the combinations" — the hard part was never the math.
The Real Difficulty Was Never the Math — It Was Buying Millions of Tickets
Knowing the strategy and actually executing it are very different problems. Mandel spent years building an operation: he recruited hundreds of investors to pool the enormous upfront capital required, then built a system of computers and printers to generate and pre-fill tickets automatically, since filling out millions of combinations by hand wasn't remotely realistic. Throughout the 1980s, his syndicate used this system to win 12 jackpots across Australia, along with roughly 400,000 smaller prizes along the way.
The 1992 Virginia Jackpot: the Operation at Full Scale
By 1992, Mandel targeted the Virginia Lottery specifically because its number pool was small enough to be logistically feasible: 7.1 million possible combinations. When the jackpot climbed above $27 million, his syndicate shipped pre-printed tickets to Virginia and arranged bulk purchases through retailers across the state, ultimately buying roughly 5 million of the 7.1 million possible combinations before the drawing. It worked — his syndicate held the winning ticket, plus a number of smaller secondary prizes on top (reported figures for the exact secondary-prize total vary between sources, so we won't put an unverified number on it here).
Investigated, Cleared, and the Rules Changed Anyway
A win of that scale and method inevitably drew scrutiny. Mandel's operation was investigated by U.S. and Australian authorities, and no fraud or wrongdoing was ever found — buying every possible combination wasn't against any rule that existed at the time. That's precisely why it mattered: his wins are a big part of the reason lotteries in the U.S. and elsewhere have since changed their rules and systems specifically to make bulk-covering every combination impractical or explicitly disallowed going forward.
Would This Work on Today's Games?
Not in any practical sense. Modern multi-state games like Powerball and Mega Millions have far larger number pools than the games Mandel targeted — Powerball alone has roughly 292 million possible combinations, not a few million. Covering that many combinations at $2 each would cost hundreds of millions of dollars in tickets alone, with no realistic way to physically purchase and process that volume before a drawing, on top of the rule changes specifically enacted to prevent it. See the long-term odds calculator for a sense of just how large modern jackpot odds really are, or the expected return rate calculator for what a single ticket is actually worth on average today.
The Takeaway
This isn't a strategy anyone can realistically use today, and it was never about predicting numbers or finding a pattern — it was pure, brute-force coverage of every outcome, funded by enough capital to make the guaranteed win profitable. It's a genuinely fascinating piece of lottery history precisely because it worked through legitimate math and logistics, not a secret system, and it's a big part of why the rules of the games themselves eventually changed. For a completely different real case — one that exploited a rule quirk instead of brute-force coverage — see the lottery loophole that made a retired couple millions.
