The Biggest Roulette Winners of All Time

Roulette has produced some spectacular winners, from Victorian gamblers who emptied Monte Carlo tables to modern players who risked six figures on a single spin.

But famous roulette stories tend to grow in the retelling.

Stakes get confused with winnings. “Breaking the bank” gets interpreted as bankrupting a casino. A large payout becomes proof of a winning system even when the result came from one extraordinarily lucky spin.

So rather than treating these stories as evidence that a losing streak is about to turn around, it is more useful to ask what actually happened.

A huge roulette win proves that an unlikely outcome happened once. It does not make the same outcome more likely for the next player.

Who Are the Most Famous Roulette Winners?

Pedro Grendene Bartelle 2017 Hit number 32 at a casino in Uruguay in a heavily reported high-stakes spin

Charles Wells and the Man Who Broke the Bank at Monte Carlo

Charles De Ville Wells produced one of the most famous gambling stories of the nineteenth century.

In 1891, the English gambler visited the Casino de Monte-Carlo and went on a remarkable roulette run. Contemporary accounts reported him repeatedly winning enough money to exhaust the reserve held at individual gaming tables.

This is where the phrase “broke the bank” needs explaining.

Wells did not bankrupt the Monte Carlo casino.

Each table operated with a working reserve of money. If a player won enough to exhaust that reserve, play stopped while the table was replenished. The table could be covered temporarily while more money arrived.

Wells reportedly achieved this repeatedly during his successful visits.

Did Charles Wells Really Win 23 of 30 Spins?

That figure appears in later accounts of his first Monte Carlo run.

Reports describe Wells winning 23 of 30 spins during one extraordinary period and taking roughly one million francs across his gambling visits.

He returned to Monte Carlo later in 1891 and again won heavily.

His exploits became famous enough to inspire the popular song The Man Who Broke the Bank at Monte Carlo.

Did Charles Wells Cheat?

No cheating method was established.

Theories have ranged from simple extraordinary luck to the possibility that Wells identified a biased wheel, but the precise explanation has never been settled convincingly.

That uncertainty is part of why the story survived.

What is well documented is that Wells won heavily and repeatedly emptied individual table banks. Why he was so successful is much less certain.

Chris Boyd’s $220,000 Bet on Red

More than a century later, British computer programmer Chris Boyd made a much simpler wager.

Boyd had spent around three years building savings of $220,000 and travelled to Las Vegas intending to risk the entire amount on one roulette spin.

The problem was finding a casino willing to accept it.

Binion’s Horseshoe eventually agreed to take the $220,000 bet, despite its normal roulette limit being lower.

What Did Chris Boyd Bet On?

Red.

Accounts from the time say Binion’s also agreed to cover the double-zero pocket on its American wheel for the wager, effectively leaving a single-zero layout for that spin.

The ball landed on red.

Boyd’s even-money wager won $220,000, leaving him with $440,000 in total.

Contemporary British newspaper archives reported the $220,000 single-spin wager in January 1994.

Was Chris Boyd’s Bet a 50/50 Gamble?

Not quite, even with one zero.

On a European roulette wheel there are 18 red numbers, 18 black numbers and one green zero.

So the probability of red is: 18 / 37 = about 48.65%.

The zero is what prevents an even-money roulette bet from being a true 50/50 proposition.

If the reported agreement to remove the 00 from Boyd’s bet is accurate, he reduced the casino advantage compared with ordinary American roulette, but red was still slightly less likely than not-red.

Ashley Revell’s All-In Roulette Bet

Ashley Revell created one of the most heavily publicized roulette bets ever in 2004.

The British gambler liquidated most of what he owned, including his car and other possessions, and took $135,300 to Las Vegas.

At the Plaza Hotel and Casino he placed the entire amount on red.

The spin was filmed.

The ball landed on red 7 and Revell received $270,600 in total, doubling the amount he had put at risk. CBS/AP reported the wager at the time.

Was Ashley Revell’s Bet Just Normal American Roulette?

There was an unusual negotiated condition.

Revell later said that he had agreed with the Plaza that if the ball landed on double zero, the spin would be declared no bet and repeated.

That removed one of the two house pockets from the practical conditions of his wager and made the bet more favourable than an ordinary red wager on an American double-zero wheel.

It still did not make red more likely than not-red.

Did Ashley Revell Prove That Betting Everything Can Work?

He proved that it can work once.

Had the ball landed on black or the losing zero outcome, the same story would have been about someone losing virtually everything he owned in seconds.

The size of the stake changes the consequences of the spin, not its probability.

This is why Revell’s wager is historically interesting but not a bankroll strategy.

Mike Ashley’s £480,000 Bet on Number 17

Sports Direct founder Mike Ashley made another famous high-stakes roulette wager at London’s Fifty casino.

He did not simply put £480,000 straight on number 17.

Instead, he placed a collection of bets centered around 17, including the straight-up number and combinations such as splits, corners, streets and broader outside bets.

The total stake was reported as £480,000.

The ball landed on 17.

A contemporary report put his winnings at approximately £1.3 million.

What Is a Complete Bet in Roulette?

A complete bet covers a chosen number in several different ways at the same time.

For number 17, that can include:

  • a straight-up bet on 17;
  • the splits containing 17;
  • the corners containing 17;
  • the street containing 17;
  • the six-line combinations containing 17; and
  • depending on the version of the bet, wider outside wagers that also win when 17 appears.

If 17 lands, many of those wagers win simultaneously.

If another number lands, some surrounding wagers can sometimes still pay depending on exactly how the complete bet was constructed.

Did Mike Ashley Win £1.3 Million or £820,000?

Both numbers can appear because reports do not always distinguish between the amount returned and the net profit after subtracting the £480,000 stake.

A reported total return of around £1.284 million corresponds to roughly £804,000 of profit after the original stake is deducted.

This is a recurring problem in gambling stories.

“Won £1.3 million” can mean £1.3 million was returned by the table, not that £1.3 million of new wealth was created.

Pedro Grendene Bartelle and Number 32

Brazilian businessman Pedro Grendene Bartelle produced one of the most widely shared roulette videos of the modern era at the Hotel Conrad in Punta del Este, Uruguay, in January 2017.

The ball landed on number 32 and Bartelle celebrated a huge win.

What is much less clear is the exact stake and payout.

Did He Turn $35,000 Into $3.5 Million?

Not on a simple straight-up number bet.

A straight-up roulette bet pays 35:1.

If you stake $35,000 on one number, the profit is: $35,000 × 35 = $1,225,000

Your original $35,000 stake is then returned as well.

That makes a $3.5 million profit mathematically impossible from a $35,000 straight-up wager alone.

Reporting at the time put the stake at roughly $35,000 and the payout above $1.2 million, while other reports claimed a much larger stake or a $3.5 million result.

The safest conclusion is therefore that Bartelle unquestionably hit number 32 for a very large payout, while the commonly repeated “$35,000 into $3.5 million” version mixes incompatible figures.

Were These Players More Skilled Than Ordinary Roulette Players?

Usually not in the sense of controlling the outcome of an unbiased spin.

Boyd and Revell made enormous even-money bets and happened to win.

Mike Ashley constructed a more complex betting position, but the roulette wheel still determined whether the position paid.

Charles Wells is harder to classify because it remains uncertain whether he was simply extraordinarily lucky or had identified something unusual about the equipment.

Historical advantage players who found biased roulette wheels are a separate category because they were exploiting a physical deviation from the expected probabilities rather than predicting random spins.

Does a Huge Bet Improve Your Chances of Winning?

No. It increases the amount won if the wager succeeds and the amount lost if it fails.

A $10 bet on red and a $100,000 bet on red have the same probability on the same wheel.

The second wager merely multiplies the financial consequence by 10,000.

Should You Copy Ashley Revell and Bet Everything on Red?

No mathematical advantage is created by doing so.

The appeal of the story comes precisely from how much was at risk.

If Revell had divided the same money into thousands of roulette wagers instead, the story would have been less dramatic, but he would also have exposed the bankroll to the house edge repeatedly instead of once.

A one-spin wager creates enormous variance. It does not turn roulette into a favourable game.

Do Losing Streaks Make a Big Roulette Win More Likely?

No. If the wheel is operating independently, the next spin does not know whether you have just lost once or twenty times.

On a European wheel, red remains 18 out of 37 on each ordinary spin.

This is why famous winners should not be used as encouragement to chase a losing streak.

Someone else’s extraordinary outcome does not change the probability facing you now.

Can Roulette Strategy Reproduce These Wins?

No betting progression can reproduce them reliably.

Martingale, Fibonacci and other staking systems change how much you bet after different outcomes. They do not make red, black or any particular number more likely to appear.

Our guide to roulette strategies explains what those systems can and cannot change.

The famous wins on this page came from rare outcomes occurring while unusually large amounts of money were exposed to them.

Who Was the Biggest Roulette Winner?

There is no definite single answer.

Historical accounts use different currencies, some report cumulative sessions rather than individual bets, and several famous figures are disputed.

Charles Wells may have won around one million francs across his extraordinary Monte Carlo runs, which was an enormous fortune in the 1890s.

Modern players such as Mike Ashley and Pedro Grendene Bartelle have generated seven-figure payouts on individual spins or sessions.

Comparing those figures directly without adjusting for stake, inflation and what “winnings” means would create false precision.

What Do the Biggest Roulette Wins Actually Tell Us?

They tell us that roulette has high variance.

An individual player can win an enormous amount of money in a few seconds. Another player making exactly the same wager can lose the entire stake just as quickly.

The fact that Revell’s $135,300 bet landed on red does not make betting your life savings sensible. The fact that Boyd also won an all-in red wager does not establish a system. And the fact that Wells produced one of gambling history’s greatest winning runs does not mean an unbiased roulette wheel can be beaten by waiting for a streak.

The stories are memorable precisely because they are unusual.
