Whether it’s in a lively casino in Vegas or playing online at home, these players were lucky enough to end up with tens of millions of dollars! Here are the six biggest casino wins of all time that will 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.

    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.
