All of the top five have come over the last two years, all on a different top online slot.

DraftKings Casino in Michigan has been the home to the three biggest slot jackpots thus far making it one of the best payout casinos online, but both New Jersey and Michigan have made recent contributions.

Local Progressive Jackpot Systems Leading to Records

Sunday’s Hollywood Casino jackpot came as part of its DropZone Jackpots, a local progressive jackpot system that is becoming a norm for most online casinos.

With these systems, a player opts-in by contributing a small extra fee to each spin that goes toward the jackpot system. These are usually around $0.10 to $0.20 per spin, but can be as high as $0.40.

The systems feature dozens and dozens, if not hundreds, of different progressive jackpot slots to choose from to be eligible for the jackpots.

The casinos offer four different levels of jackpots, including a Mega or Grand jackpot that has led to these multi-million dollar wins.

Here’s a look at some of the online casinos featuring local progressive jackpots.
