MGM Exclusive Jackpots — $2,000,000+ Jackpots
BetMGM Casino is one of the top online gambling brands in the US, so it is no surprise that MGM, the company behind it (and Borgata Casino), has come up with several exclusive titles that you can only play on these sites. This group includes several progressive jackpot titles, and these are definitely some of the best payout slots in the US.
Games like MGM Grand Millions, Mirage Mega Magma, Loot 'En Khamun, and Bison Fury all share the same progressive jackpot. In New Jersey, the progressive has been known to get well over $2 million, while in states like Michigan and Pennsylvania, it tends to fluctuate between $400,000 and $1,000,000.
According to a recent report from BetMGM, the two largest online slot machine payouts won playing their exclusive slots happened in early 2023 in New Jersey, with lucky players taking home $2.8 and $2.4 million, respectively.
You cannot go wrong with these titles if you are looking for US slots with the highest payouts. There are several big winners each year and a multitude of smaller jackpots awarded along the way.
IGT’s Mega Jackpots Series — $1,000,000+ Payouts
IGT is one of the game suppliers you will find at almost all online casinos in the USA, offering some of the highest payout slots around. The provider features an impressive library of titles, but if it is a big win you are after, you should check out its Mega Jackpots series.
All games participating in this progressive jackpot pool are clearly marked, so you should have no problems finding them, but some of the most popular titles to look out for are Golden Goddess, Siberian Storm, Mistress of Egypt, Cleopatra, and Wolf Run.
When it comes to the best payout slots from the Mega Jackpots series, there have been several $1,000,000+ jackpots and many mid-six-figure wins over the years, so these games are ideal for all jackpot chasers.
What is more, IGT is one of the oldest game providers, which means that many of the games you will get to play are classic titles that quite a few players will recognize from their days of playing at land-based casinos across the country.
As mentioned, almost all US casinos feature these titles — you can take your pick from BetMGM Casino, FanDuel Casino, DraftKings Casino, Borgata Casino, and BetRivers Casino.

3. Greentube (Novomatic) Progressives — $200,000+ Jackpots
Novomatic is another classic game provider that has dominated live casino floors in Europe for decades. With the explosion of online casinos, they created an online division called Greentube and joined the Internet party.
Always on the lookout for new markets, Novomatic has found its way into the USA as well, and these days, you will find plenty of Greentube titles at US online casinos, including many with progressive jackpot prizes up for grabs.
While some of these offer relatively modest max wins of $10k to $20k, there are also those with lower six-figure jackpots, such as Noble Peacock, Wings of Fortune, and Great American Wilds, as well as the games from the Diamond Cash series, such as Mighty Elephant and Oasis Riches.
BetRivers Casino features an excellent selection of slots, including the highest payout slots by Greentube. If these fit your gaming preference, we recommend signing up with BetRivers and claiming their generous welcome bonus — we’ve ranked it as the best online casino bonus in the US — to get you started.
You can also find Novomatic jackpot slots at Borgata Casino.
