  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.

Tips – How to Win Jackpots on Slot Machines

While hitting the jackpot is not guaranteed, there are a few suggestions that can 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 if you want 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, there is more risk when one plays big, but the rewards can be out of this world!
