Biggest Casino Winners

The biggest casino winners are often rich businessmen and women. However, there are also some winners you may not expect! We’re going to be showing you some of the biggest casino winners on this page. Please note, this list doesn’t include online casino winners, and it doesn’t include poker winnings; it’s focused entirely on wins from land-based casinos.

What Is The Biggest Casino Win in History?

The biggest casino win ever was added to record books when Australian billionaire Kerry Packer started playing blackjack and baccarat at the MGM Grand in Las Vegas. While his exact winnings are unknown, he won between $20 and $40 million! We’ll tell you more about his story – and other big winners – in the rest of this blog.

If you’re more interested in online gambling, rather than land-based casinos, then make sure to check out our general guide to online casino gambling. It shows you what online gambling is, how to get started, and the best online casinos to play at.

Kerry Packer – MGM Grand

Kerry Packer was an Australian media magnate and billionaire businessman. At one point, he was one of the richest people in the world. He passed away in 2005. When Packer was alive, he was well-known for having a goal-oriented personality. He utilized aggressive business tactics – and was famed for his passion for gambling. Packer owned numerous media assets, including the Nine Network, and was a key developer in the Australian media industry.

Packer also holds the record for winning the most amount of money at a land-based casino in a single day. When he ventured to the MGM Grand in Las Vegas, he played ultra-high stakes games, namely blackjack and baccarat. He started to win so much money that it became impossible to keep track of it.

According to observers, Packer ended up winning between $20 and $40 million! However, he subsequently ended up blowing a lot of this money – placing silly bets and giving away casino chips to random people! However, throughout the night, he left over $1 million in tips – making him one of the biggest casino tippers in history, too!

Anonymous – Excalibur Casino

Next up is an anonymous player, who managed to hit a giant jackpot of $39.7 million while playing a slot in the Excalibur Casino in Las Vegas. This happened way back in 2003 and the millions were won from a bet of just $100.

The winner of this jackpot chose to stay anonymous, so there’s not much known about them, except that they were a software developer from Los Angeles. In fact, there’s nothing more to say about them, so let’s move on and look at the next person on the list!

Please note: there have been several huge slot wins in casinos, but to ensure this list has a bit of variety, we’re only going to mention the biggest one!

Don Johnson – Atlantic City

Don Johnson is one of the best-known figures in Atlantic City – and for good reason. Over a six-month period, he won more than $15 million from three land-based casinos in the city – all without cheating or counting cards. Johnson developed his own unique blackjack system – and this was combined with some lucrative deals land-based casinos in Atlantic City were offering after the 2008 financial crisis.

Thanks to these deals, Johnson was able to claim as much as 20% cashback on his losses. When combined with his strategy – which involved sticking to the strategy, playing the perfect game, and looking for tables with the best odds – he managed to win millions of dollars.

As a result of his winnings, Johnson was banned from most casinos in the US. Those that didn’t ban him will not offer him any type of cashback or rebate promotions, and he remains one of the biggest casino winners in the world.

Mike Ashley – Fifty Casino

The biggest casino win in history may not have landed in London – but the city has been host to some pretty notable wins of its own. The UK also has one of the world’s strongest economies, which is why land-based casinos tend to do pretty well in the country.

In 2008, Mike Ashley – the former billionaire owner of Newcastle United – decided to head to a trendy London casino called Fifty. He spent just 15 minutes playing roulette – and by the end of his session, he ended up winning more than $1.6 million!

According to croupiers and spectators, as soon as Ashley walked into the casino, he headed to the roulette table. Long before placing his bet, he loudly announced that he would be betting on the number seven and only the number seven. Clearly, luck was on his side, as number seven rolled right in – and he walked away with a profit of more than $1.5 million!

Charles Wells – Monte Carlo

One of the biggest casino winners in history had an incredibly interesting life. A man called Charles Wells was well-known for breaking the bank, and he was, reportedly, a compulsive gambler. He frequented the roulette table at various land-based casinos. Convinced that a big win was coming his way one day, he went to a bank and took out a loan to gamble with!

According to reports at the time, Wells went on to play roulette for 11 straight hours – and ended up “breaking the bank” a total of 12 times! His roulette session was so successful, the land-based casino he was playing at – the Monte Carlo – didn’t have enough chips to continue paying his winnings. As a result, he ended up leaving the casino with 1 million francs in cash!

Please, remember these are only a few examples of successful gaming sessions. If you enjoy playing online or at land-based venues, stick to responsible gaming principles. Play for fun, stay within your budget, and don’t try to win back your losses.
