Biggest Online Slot Win Of All Time In The US

One New Jersey woman made history this Thanksgiving holiday, nabbing a jackpot to be thankful for. The lucky winner recorded the biggest online slots jackpot in US history, totaling $3,500,000.

Dori B. (her last name was kept private) won the massive jackpot playing the $10 slot MGM Grand Millions at BetMGM Casino skin Borgata Casino in New Jersey.

About MGM Grand Millions

The slot game that paid out the jackpot, MGM Grand Millions, is available in a handful of US markets. Players can enjoy the game and get the online casino bonus in Michigan, a New Jersey promo code, a West Virginia bonus code, and a Pennsylvania bonus at BetMGM Casino and Borgata Casino in NJ and PA.

The game has a history of paying out big jackpots, which adds to its appeal for online slots enthusiasts. In August of 2021, the MGM Grand Millions jackpot paid out twice in a single day for a total of $450,000 in winnings.

MGM Grand Millions has 243 possible paylines. It’s a 5×3 reel array, which will feel familiar to most online slots players.

How To Play The Slot for Free

New players can try the MGM Grand Millions slot for free with bonus money. The BetMGM promo code is SHARPCASINO for $25 free on signup, plus a 100% deposit-match bonus up to $1,000. Unfortunately, you can’t use the $25 no-deposit bonus on progressive jackpot slots, but it’s fair game for the deposit-match bonus. Additional terms and conditions apply, but this is one of the best deals among US online casinos.
