10 Biggest Jackpot Wins at USA-Friendly Online Casinos

Lots of people want to know the 10 top biggest winners at US casinos online but finding that information is tricky. Some casinos are open to US players, but the winning player might come from another country. So, which wins do you include on a list like this?

Furthermore, some casinos are based in the US and abide by local laws, whereas other online casinos are offshore yet still welcome US players to sign up. We also know that some players remain anonymous - and it's easy to see why they would. If you won several million dollars, would you want to splash the news around?

We guess not!

So, let's check out some of the biggest winners and see whether they might inspire you to play the same games.

Millionaire winners on Mega Moolah

The list of biggest progressive jackpots won online is filled with two slot titles - Mega Moolah and Mega Fortune. The current top prize was worth a cool $23.6 million, won by one person playing the Absolootly Mad Mega Moolah slot - so, still part of the Mega Moolah range of slots. The biggest progressive won to date for the original Mega Moolah title was just short of this on $23.5 million.

Mega Moolah was created by Microgaming, and it took several years before they began to create sequels using the same famous title.

Millionaire winners on Mega Fortune

The jackpot in this game typically pays out around $4.2 million US dollars each time, although of course, that's based on averages. While the jackpot amount may be a lot lower than the one seen in Mega Moolah, it stands as one of the most popular games around… and it uses a theme based on riches, too.

The biggest prize was €17.8 million, going to someone in Finland. No one in the top 10 of prizes for that slot was from the US, but you will find it at several online US-friendly casinos.

How to find the best progressive jackpot titles for US players

There are plenty of other slots around that offer progressive jackpots, so you can find the ideal theme for your preferences. Major Millions and Hall of Gods appear on the list as well.

Be ready for a lower RTP than other games might offer

With progressive jackpot slots and other games, a slice of each real bet goes into the jackpot amount. Everything else is used to pay out regular prize amounts from the game. This means the total RTP is often lower than it would usually be, to cater for the biggest prize of all.
