Progressive jackpots

Before we jump into specific games, it’s imperative to understand what makes jackpots so large. Most online slot jackpots are progressive, meaning they grow over time.

1. Mega moolah

Often called the “millionaire maker,” Mega Moolah is perhaps the most famous progressive jackpot slot in the online casino world.

2. Mega fortune

NetEnt’s Mega Fortune is another heavy hitter in big jackpot slots. This luxury-themed game takes players into a world of yachts, diamonds, and champagne.

Mega Fortune has consistently paid out multi-million dollar prizes, with its biggest win €17.8 million in 2013.

3. Jackpot giant

Playtech’s Jackpot Giant is a relatively new entry into the big jackpot scene, but it’s quickly making a name for itself. This prehistoric-themed slot rtp zeusgg features a single progressive jackpot that regularly climbs into the millions. The game’s colourful graphics and fun bonus features make it enjoyable to play, even when you’re not hitting the big win.

4. Age of the gods series

Playtech’s Age of the Gods series deserves special mention. While not a single game, this series of mythological-themed slots feed into the same progressive jackpot network. This means jackpots grow extremely quickly, often reaching multi-million dollar amounts. With various games in the series, players can choose their preferred theme while still shooting at the same massive jackpots.

5. Hall of gods

Another NetEnt creation, Hall of Gods, takes players into Norse mythology. This slot has paid out several multi-million dollar wins over the years. The game features three progressive jackpots – Mini, Midi, and Mega – with the Mega jackpot often reaching millions.

6. Arabian nights

Don’t let the relatively simple graphics fool you – NetEnt’s Arabian Nights packs a serious punch in jackpots. This Arabian-themed slot has a single progressive jackpot that has created several millionaires since its release. While it might not reach the heights of Mega Moolah or Mega Fortune as often, its jackpots are still life-changing.

7. Gladiator jackpot

Based on the hit movie, Playtech’s Gladiator Jackpot is another popular choice for big-win hunters. The game features high-quality graphics and clips from the film, along with a progressive jackpot that regularly reaches seven figures. The jackpot game is triggered randomly, adding excitement to every spin.

Every time a player makes a bet, a small portion of it is added to the jackpot pool. This continues until someone hits the winning combination and takes home the entire prize. After a win, the jackpot resets to a predetermined base amount and grows again.
