The Biggest Casino Wins of All Time


While we all know that playing casino games carries some risk, the fact is that this same risk can lead you to incredible winnings. Many tried their luck, leading them to victories that changed their lives forever.

Although the casino always has an advantage, players always have the opportunity to win. Additionally, when the lucky stars align, they can expect an experience they’ll talk about for a lifetime.

This short guide will look at the highest casino wins ever. Are you ready?

$20.5 Million – Absolutely Mad Mega Moolah Slot

In 2021, a Belgian player won one of the biggest prizes in a casino game. This lucky player who decided to stay anonymous used a stake of around $18 when he hit the massive reward.

Many slots, like the Absolootly Mad Mega Moolah slot, offer tiered progressive jackpots. The 40 Burning Hot slot by Amusnet Interactive, which you can check at, is another excellent example.

Interestingly, the Absolootly Mad Mega Moolah slot is part of Microgaming/Games Global’s online progressive jackpot network. This means the jackpot takes portions of each bet wagered in land-based and online casinos. Still, the lucky player used an online casino.

$22.6 Million – Megabucks Slot

Apparently, it’s never too late to become a millionaire. Johanna Heundl won $22.6 million at the age of 74. She played the Megabucks progressive jackpot slot when she won a round in its special mini-game.

This time, we have an example of a winner who used their budget of $100 and decided to risk more – an additional $100. So, after spending $170, she won $22.6 million. The woman said she was thrilled, thinking she had won $2 million, but when Johanna realized she had won over $22 million, she nearly passed out.


Heundl said that she had been a fan of online gambling, especially slots, for many years. It was one of the rare moments where she used more money than planned for this purpose and still advised players to stick to their predetermined budgets. This is the only way to stay responsible.

$27.6 million – Megabucks Slot

Megabucks is one of the most famous progressive jackpot slot machines. It was developed by IGT. Keep in mind that it’s available only in brick-and-mortar casinos. In 1998, a 68-year-old woman from Las Vegas and a passionate slot player won over $27 million while playing this game.

You’ll probably understand why she wanted to stay anonymous, given the amount. Even though she could take the whole amount at once, she chose to get the money in installments. This way, she received about $1.1 per year, and if she were still alive, she would have received the last installment last year.

Although this may look a bit weird given her age, she had three children and several grandchildren and spent this money with them.

$34.9 Million – Megabucks Slot

The Megabucks slot by IGT brought incredible luck to another woman. This time, the winner shared her name with the world – Cynthia Jay.

What’s unique about her story is that she worked as a cocktail waitress at a Strip casino. Her routine included wagering $21 at progressive slot machines almost daily. That day, she received a tip at the end of her shift and spent an extra $6, which brought her breath-taking $34.9 million.

Like the Las Vegas winner, she used the opportunity to receive 25 annual installments (around $1.4 million per year). A few weeks later, she married and did her best to help her family (her brothers and sisters) with the money she had won.

$39.7 Million – Megabucks Slot

The Excalibur Hotel-Casino in Las Vegas was where a 25-year-old man won a fantastic $39.7 million after hitting the main jackpot prize of the Megabucks slot machine. This happened in 2003, meaning this amount was even more valuable then. The winner worked as a software engineer in LA and went to Las Vegas to visit his friends and family.

He was more into sports betting, but his uncle reminded him he should try some progressive slots because they pay massive amounts. According to the winner, he spent less than $100 when he hit the main prize.


Over 60 people won the Megabucks progressive jackpot in the past two decades, but this is the biggest single win.

$40 Million – Multiple Casino Games

The case of Kerry Packer is interesting in several respects. Namely, the first thing that jumps out here is that the famous Australian billionaire who died in 2005 did not play a single game to reach the highest winnings in the history of gambling.

People at the MGM Grand casino in Las Vegas claim that Packer mostly played blackjack. He focused on high-stakes tables dedicated to this popular card game.

In addition to blackjack, he is said to have played baccarat, craps, and other table games. The stakes also set it apart from the rest of the winners on this list. He often used bets of $200,000 or even $250,000 in one round.

Witnesses also emphasize that Packer had incredible winning streaks, so he sometimes played several hands at once (blackjack), and most were winning.

This did not happen in one day but over several days. Ultimately, Kerry Packer earned 40 million dollars, still an unsurpassed record. With this, this billionaire became a legend in gambling circles worldwide.
