The biggest roulette wins are a mix of three things: genuine advantage play against flawed wheels, eye-watering single bets by wealthy gamblers, and a fair amount of legend that has grown in the retelling. Many older figures are estimates from press reports rather than audited records, so treat the amounts as ballpark, not gospel. What follows separates the verified from the embellished.

The Ten Most-Cited Roulette Winners

Rankings vary between sources because some count lifetime advantage-play totals while others count a single dramatic spin. The table below lists the names that come up most often, with amounts in their original reported form. The notes flag where a figure is contested.

The Advantage Players: Beating a Broken Wheel

The largest sustained roulette wins in history did not come from luck or a betting system. They came from finding wheels that were not truly random. A wheel with a worn pocket, a tilted rotor, or a manufacturing flaw can favour certain numbers over thousands of spins. Catalogue that bias with enough data and you flip the house edge in your favour.

Richard Jarecki, a medical professor, spent the 1960s and 70s doing exactly that across European casinos, recording results by hand and betting the numbers the wheels favoured. Joseph Jagger did the same a century earlier in 1873, hiring clerks to log a Monte Carlo wheel before betting its biased pockets, the feat that inspired the phrase “the man who broke the bank.” The García-Pelayo family modernised the approach in 1990s Spain with computer analysis. None of this is prediction in the fortune-telling sense. It is patient measurement of a physical defect, the same territory covered in our look at advantage play and where the law draws the line, and these names recur throughout the history of famous roulette players.

That route is essentially closed today. Modern wheels are precision-engineered, monitored, and rotated, and the kind of long-running bias these players exploited rarely survives now. Understanding why means understanding the house edge itself: on a fair wheel, no record of past spins helps you, because each result is independent.

The Big Single Bets

The other path to a famous win is simpler and far riskier: stake an enormous amount on one spin and get lucky once. No skill, no edge, just nerve and a bankroll, the territory of high limit roulette.

Ashley Revell is the purest example. In April 2004 the 32-year-old Londoner sold his house, his car, his clothes, everything he owned, raising $135,300. He carried the cash to the Plaza Hotel in Las Vegas, placed the lot on red, and watched the ball settle into red 7. He walked out with $270,600, the bet filmed by Sky for a mini-series. Had it landed black, the story would be a cautionary tale instead of a legend. The wheel did not care which.

Mike Ashley, the Newcastle United owner, took a more calculated route in 2008 with a “complete bet” on 17, covering the number and its surrounding combinations, for a payout reported around £1.3M. A complete bet is expensive to place but pays from many angles when the number lands, which is exactly why the real Bartelle story below is more interesting than the headline.

The Bartelle Number: 3.5 Million or 1.2 Million?

Pedro Grendene Bartelle’s 2017 win at the Hotel Conrad in Punta del Este is the most-cited modern roulette story, and also the most garbled. The popular version says he bet $35,000 on number 32 and won $3.5 million. That cannot be right. A straight-up number pays 35:1, so $35,000 on 32 returns about $1.2 million, not $3.5 million.

Two explanations survive scrutiny. Either the stake was closer to $100,000, as the original Spanish-language report stated, or, more likely from the video, Bartelle placed a modified complete bet: chips on 32 plus the splits, corners and streets around it. When 32 landed, every one of those bets paid at once, which is how a smaller-looking pile produces a much larger return. The often-quoted “$35k turned into $3.5M on a single number” is the press confusing a complete bet for a straight-up, helped along by currency conversions between Uruguayan pesos, euros and pounds.

Did Einstein Really Say You Can’t Beat Roulette?

Almost every roulette article eventually quotes Albert Einstein: “No one can beat roulette unless he steals money from the table while the croupier isn’t looking.” It is a good line. It is also almost certainly not his.

Researchers who track quote origins trace the saying to a 1968 newspaper series about the gambler Nick the Greek, not to anything Einstein wrote or said. The standard reference work on his quotations files it under “Probably Not by Einstein.” The sentiment happens to be mathematically sound, since no betting system overcomes the house edge, but the attribution is folklore. We mention it because you will see it presented as fact everywhere else, and accuracy is the point of this page.

Why the Rankings Never Quite Agree

No two “biggest winners” lists match, for a few honest reasons:

• Some lists count a single session, others count a lifetime of advantage play, which puts Jarecki and Walters far above any one-spin gambler.
• Older sums are inflation-adjusted differently, or not at all, so a 19th-century figure can swing by millions depending on the method.
• Many historical wins come from newspaper accounts written for drama, not from casino records, so the amounts are estimates at best.
• Currency conversions across decades and borders introduce errors, as the Bartelle case shows.

The reliable takeaway is not a precise leaderboard. It is the pattern: the biggest sustained winners beat broken wheels with data, while the biggest single wins were huge gambles that happened to land. Neither route is repeatable on a modern, fair table, which is the same conclusion our breakdown of common roulette myths reaches from the other direction.
