Illinois Business Consultant – $21,346,952.22 in 1999

The first of our top 5 Vegas casino jackpot winners walked into a Vegas casino in June 1999. An un-named self-employed business consultant from Illinois gambled $10 on the Megabucks slot machine at Caesars Palace Casino and his life changed forever.

What happened next is a moment that he will never forget, as the 49-year-old was soon over $21 million richer. Incredibly, he won this mind-boggling sum on his very first spin, so he had gambled just $10 to win it.

This has to go down as one of the best $10 investments in history.

Johanna Heundl – $22,621,229.74 in 2002

If we fast forward a few years we see a 74-year-old lady from Covina in California scooping a slightly bigger sum on another Megabucks slot machine. This time the dramatic win happened in Bally’s casino in Las Vegas, and it was an Austrian-born widow who walked away with a giant smile on her face.

Apparently, the second of our top 5 Vegas casino jackpot winners was on her way to have breakfast when she made the smart decision to play a slots machine. She wagered $170 and, at first, she thought that she had won £2 million, which would still have been a pretty good win, to be honest.

Johanna was described at the time as a regular visitor to the casinos in Las Vegas so it just proves that persistence is often the key to winning these games.

Retired Flight Attendant – $27,580,879.60 in 1998

We need to go back a bit earlier in time to find the next person in the list of the top 5 Vegas casino jackpot winners. This time, the site where the moment of good fortune took place was Palace Station Casino.

The interesting thing about this win was that the 67-year-old who got lucky benefitted from a last minute change of mind. She was planning to wager just $100 that day but appears to have got so caught up in the excitement that she ended up betting $300 instead.

Thankfully, it worked out perfectly as she pulled off the 3rd biggest win in Las Vegas history. This happened in November 1998 and, strangely, the same woman had already won almost $680,000 on the Wheel of Fortune game in the same casino that very same day.

Cynthia Jay-Brennan –$34,959,458.56 in 2000

The 2nd biggest of the top 5 Vegas casino jackpot winners also got her lucky win around the turn of the century. In fact, it happened in January 2000.

Cynthia Jay-Brennan was a 37-year-old cocktail waitress who decided to see whether she could pick up some winnings from the Desert Inn when she was out with her family. What happened next went beyond her wildest dreams, as she got an astonishing Megabucks jackpot of almost $35 million.

Sadly, her massive pay-out was followed by tragedy. A drunk driver crashed into her a few weeks later, leaving her paralysed and killing her sister.

Looking back on her big win, she said in later interviews that she wasn’t even fully aware that she had won such a stunning amount of money until she heard people all around her shouting and whistling. At the time, it was the biggest ever jackpot win in Las Vegas, although it would be beaten a few years later.

Software Engineer – $39,710,826.36 in 2003

The number one spot on our list of the top 5 Vegas casino jackpot winners was claimed in March 2003. The winner this time was a 25-year-old Los Angeles software engineer who decided to remain anonymous after his win and whose name has never been publicly revealed since then.

The life-altering moment came after he had bet some $100 on a Megabucks jackpot machine in the Excalibur Casino. The winning bet was for just $3. Incredibly, this won him close to $40 million, as the progressive jackpot had been building up for close to a year before he won it.

This is still the record Las Vegas jackpot pay-out and the odds of him winning it have been calculated as being in the region of 1 in 16 million.

Record Online Casino Wins

While the top 5 Vegas casino jackpot winners all won a fortune on the city’s land-based casinos, there have also been plenty of mammoth wins record in online casinos in recent years as well.

The biggest of all came in 2013, when a Finnish man in his 40s won $24 million with a 25 cents stake by claiming the Mega Fortune progressive jackpot. The winner remained anonymous but said that he laughed and cried at the same time when he found out about the amount of the win.

Before that, a very lucky Norwegian man scooped €11.7 million on the same game. He said that he was only playing because he couldn’t get to sleep at night but ended up in dreamland anyway when he grabbed the progressive jackpot.
