Elmer Sherwin – The Mirage Casino, Las Vegas (1989)

In 1989, Elmer Sherwin, a 92-year-old retiree from Henderson, Nevada, made history by winning the largest slot machine jackpot of all time at The Mirage Casino in Las Vegas. Just a few days after The Mirage opened its doors, Sherwin walked away with a $4.6 million jackpot from a Megabucks slot machine.

Sherwin’s story is truly one of a kind, as he not only won the largest slot machine jackpot of all time once, but twice! 16 years later, in 2005, at the ripe age of 76, Sherwin won another $21.1 million on a Megabucks machine at the Cannery Casino in Las Vegas.

On the day of his first win, Sherwin’s bankroll had run out, so he borrowed $20 from his then-wife to play the Megabucks slot. It only took him 90 minutes to win and claim the title of the largest slot jackpot won at The Mirage. Sherwin stated that he had a feeling that day was going to be lucky and that he had a premonition that he was going to win big.

Sherwin’s win was not only a life-changing event for him but also for the casino industry, as it marked the beginning of the Megabucks slot machine craze. Megabucks is a network of slot machines linked together across different casinos, with a progressive jackpot that grows with every coin played until one lucky player hits the jackpot.

Anonymous – Excalibur Casino, Las Vegas (2003)

In 2003, an anonymous player hit the jackpot of a lifetime when they won $39.7 million from a Megabucks slot machine at the Excalibur Casino in Las Vegas. This is widely considered to be the largest slot machine jackpot in history.

The story goes that the winner, a software engineer from Los Angeles, was on vacation in Las Vegas and decided to follow his uncle’s advice to play the Megabucks slot at the Excalibur Casino. After spending just a few dollars, the player hit the life-changing jackpot and became an instant millionaire.

The anonymous winner chose to remain anonymous and did not reveal their identity to the public. They did not speak to the media, nor did they make a public appearance to claim their prize. They simply collected their winnings and went back to their normal life.

Despite their anonymity, the winner’s story has become a legend in the casino world. The $39.7 million jackpot they won is still the biggest ever in the history of slot machine jackpots, and it has inspired countless players to try their luck at the Megabucks slot machine.

Anonymous – Grand Mondial Casino (2018)

In September 2018, an anonymous player won a staggering $10,423,223 while playing the Mega Moolah slot machine at Grand Mondial Casino. The win broke the previous record of $5.5 million, which had been set in April of the same year.

Mega Moolah is a progressive jackpot slot game that is known for its massive payouts. The game is linked across multiple online casinos, which means that every time a player spins the reels, a small portion of their wager is added to the progressive jackpot. The jackpot keeps growing until one lucky player hits the winning combination and wins the entire prize.

The anonymous winner was playing the game for just a few minutes when they hit the jackpot. They were playing with a $0.25 bet when the winning combination of symbols appeared on the screen. The player was understandably in shock and could hardly believe their luck.


Katrina Bookman – Resorts World Casino, New York (2016)

In 2016, Katrina Bookman, a resident of New York, made headlines when she won a $43.8 million jackpot from a Sphinx slot machine at Resorts World Casino in New York. However, the casino claimed that the machine malfunctioned, and Bookman was not able to claim her winnings.

Bookman was playing the Sphinx slot machine when the machine displayed the message “Printing Cash Ticket $42,949,642.76.” She was understandably ecstatic, and she took a photo of the machine’s display as proof of her win. However, when she went to the casino’s customer service to claim her prize, she was told that the machine had malfunctioned and that she was not entitled to any winnings.

The casino offered her a complimentary steak dinner instead, but Bookman was not satisfied and decided to take legal action against the casino. The case is still ongoing, and the outcome is yet to be determined.

This incident highlights the importance of reading the terms and conditions of the slot machines before playing, as well as understanding the rules and regulations of the casino. It also serves as a reminder of the potential risks that come with playing slot machines, especially the progressive jackpot ones.
