Biggest Casino Winners of All Time!

Ask any slot player to tell you their biggest wish, and you’ll hear them say, “It’s to win the jackpot!” However, it ends up being only a wish for most of them. For a select few whose luck seems decided by the heavens, they end up striking gold!

Whether in a lively casino in Vegas or playing online at home, these players were fortunate enough to take home tens of millions of dollars!

Here are the six highest casino wins that show you it is all possible.

  1. Excalibur Casino in Las Vegas – $39,710,826.36

    The biggest casino jackpot winner in history was a young software engineer who played the Megabucks slot machine at the Excalibur Casino in Vegas and won. It happened way back in 2003, and the lucky winner spent only $100 before hitting the $39.7 million jackpot.
  2. Desert Inn, Las Vegas$35 Million

    Imagine walking into a casino after a tiresome work shift and getting out a millionaire! That’s the story of Cynthia Jay Brennan, who won $35 million at the Desert Inn Casino in 2000. Cynthia was a cocktail waitress who got out of her shift, visited the casino, played the Megabucks slot, and won big. However, a few weeks later, she was involved in a tragic accident that left her paralyzed for months.
  3. Palace Station Casino, Las Vegas – $27.6 Million

    Megabucks once again awards another lucky millionaire, but this time at the Palace Station in Vegas. Less is known about the winner. Only that she was a retired flight attendant, spent close to $300, and won the jackpot in 1998.
  4. Finnish Poker Player Playing Mega Fortune$24 million

    Talk about making a fortune! An anonymous poker player from Finland won $24 million by playing Mega Fortune online. So for those who love playing online, know that you can earn millions right on your couch. It gets even better; the player only wagered 25 cents!
  5. A Veteran Playing Megabucks $21 million

    The story of Elmer Sherwin, a WWII veteran, will leave you in awe. Yes, he did win $21 million playing Megabucks at the Cannery Casino in 2005, but this was his second time. His first jackpot win was in 1989 when he played the Megabucks slot machine at the Mirage Hotel & Casino and won $4.6 million. After donating a considerable part of the $21 million to Hurricane Katrina victims, Elmer won people’s hearts.
  6. Mega Moolah$18.2 million

    Mega Moolah has become one of the most popular jackpot slots, with multiple winners taking home millions. One was Jon Heywood, a British soldier who only spent a quarter to win the $18.2 million jackpot. It was life-changing for Jon as he spent some money on his father’s medical treatment.

Top Progressive Slot Machine Jackpot Wins

Not every slot player has the chance to get their hands on a fantastic jackpot, but a few lucky ones do. Lady luck favors some players with huge jackpots from time to time. Have a look at some of the biggest progressive slot machine wins of all time.


Megabucks Slot Jackpot

Megabucks is a classic progressive jackpot slot developed by IGT about three decades ago. Since then, different Megabucks versions have been introduced, including 3-reel and 5-reel options. The biggest jackpot awarded was $34,955,490 on January 26, 2000.

Mega Fortune

Mega Fortune Slot Jackpot

Mega Fortune is NetEnt’s best-known 5-reel, 3-row classic slot. Although the layout is simple, it has many exciting elements, such as a free spins feature that triggers a 5x multiplier. The highest jackpot ever won on Mega Fortune was $17,861,800 in 2013.

Mega Moolah

Mega Moolah Slot Jackpot

Mega Moolah is another top NetEnt slot and perhaps its most popular one ever. This classic video slot features 5 reels, 3 rows, 25 paylines, and four progressive jackpots. On September 28, 2018, a casino player won $21,429,792 on Mega Moolah.

Tips – How to Win Jackpots on Slot Machines

While hitting the jackpot is not guaranteed, a few pointers can help increase your odds. Check out these tips when playing progressive online slots.

  1. Choose High RTP Games

    Playing slots for fun is great, but you have to play high RTP (return to player) slots to improve your chances of winning. Choose slot games with an RTP of 95% or higher.
  2. Start With Free Versions

    Not all slots have free versions for you to try, but this is an excellent option to start with when they do. Once you are comfortable, you can move on to real money play and have a better chance at winning.
  3. Play Big to Win Big

    If you want a chance at winning, you have to bet big on every spin. If you play the least possible coins on top slots, you cannot expect to get your hands on a jaw-dropping jackpot. Of course, when one plays big, there is more risk, but the rewards can be out of this world!
