Every gambler dreams of winning big at the casino one day. Looking to motivate yourself? Here are the five biggest casino wins in history


Aside from the thrills and excitement that come with playing their favourite games, one of the reasons why casino players at a no deposit bonus casino enjoy gaming is the dream of winning something big. A prize big enough to change their lives in a split second.

Over the years, some lucky players have been able to fulfil their dreams, winning millions of dollars from very simple bets. These life-changing wins are always a source of inspiration to players globally, and this article will discuss these players and their amazing exploits.

The History of Casino

These days, players no longer have to travel to Las Vegas or any fancy casino locations to win such huge amounts; there are now gamers who claim millions in winnings from placing bets at online casino jackpots.

While it's true that dozens of players have won millions of dollars from playing casino games, it's also essential that you remember that hitting the jackpot requires a huge element of luck, and everyone might not be so lucky. That's why it's important you practice responsible gambling and only play with money you can afford to lose. That way, even if your dream win doesn't come today, you can be financially secure and hope for it to come another day. Some of the stellar triumphs that make our list include:

  • Kerry Packer's famous $40 million jackpot win;
  • An anonymous $39.7 million Megabucks win;
  • Cynthia Jay-Brennan’s $34.9 million Megabucks win;
  • Johanna Huendl's $22.6 million win on Megabucks;
  • The retired anonymous 27.5 million Megabucks jackpot win.

Kerry Packer - $40 Million

Kerry Packer was a media tycoon and a multi-billionaire. At the time of his death, he was the richest man in Australia and one of the most influential men in the world. But aside from his multiple businesses and wide political influence, Packer was famous for his love for gambling.

According to reports, even the biggest casinos in Las Vegas and around the world were wary of hosting Packer because his wins and losses could significantly influence their finances. He proved this in 1997 when he reportedly won up to $40 million at the MGM Grand Casino in Las Vegas. Some sources claim that he won that by playing six blackjack hands at a time and staking $200,000 per hand!

Anonymous - $39.7 Million

In 2003, a 25-year-old software engineer from Los Angeles came to Las Vegas to visit his family and keep track of basketball's March Madness event with his friends. After a brief conversation with his Uncle, where he was told about IGT's Megabucks slot machine, he entered the Excalibur Hotel-Casino on the Las Vegas Strip with a few hundred dollars in his pocket.

The engineer who asked to be kept anonymous wagered $100 on the Megabucks machine, and according to him, he looked away for an instant, and when he looked back, he saw the winning symbols all lined up; he had won a whopping $39,713,982.25! Setting the record for the biggest Megabucks and slot machine win in history.

Cynthia Jay-Brennan - $34.9 Million

Cynthia's story is one that proves that anybody can be a winner. She was a cocktail waitress at the now-rebranded Monte Carlo Casino and, on a night out with her boyfriend, decided to play the Megabucks slot machine at the Desert Inn Hotel and Casino. This was the first time she'd be playing in a while, and she agreed to set aside $100 for the session. On her final spin, three flashing Megabucks symbols appeared on the screen, indicating that she'd won a jackpot of a little under $35 million.

A jubilant yet composed Cynthia gave the Monte Carlo Casino her two-week notice and began planning her wedding. Unfortunately, her story did not end well. Barely two months after her win, she was the victim of a car crash that killed her sister and left her quadriplegic.

Anonymous - $27.5 Million

In November 1998, a 67-year-old retired flight attendant and longtime Las Vegas resident got the best retirement package anyone could ever ask for at the Palace Station Resort. The woman had decided to only wager $100 on the Megabucks slot machine but was halfway into her third hundred dollar bill when she hit the $27.5 million jackpot, creating the record for the highest Megabucks jackpot win.

However, the lucky woman was not new to big casino wins. Some months back, she had won the $680,000 jackpot in the same casino when she came with her husband to celebrate his retirement. When asked about her wish, she asked to be kept anonymous. According to her, she wants to be able to visit the supermarket without people noticing her.

Johanna Heundl - $22.6 Million

70-year-old Johanna just wanted to celebrate her birthday in Las Vegas and ended up with a $22.6 million jackpot win. According to her, she was on her way to breakfast when she decided to stop by and try her luck.

She was hoping to win the $3,000 progressive prize and put $100 into the machine, but it went bust. Johanna was $70 into her second $100 when she hit the mega jackpot. She alerted the staff because she thought it was a $2 million win, only to find out she'd won a whopping $22.6 million.
