Since then, the Mega Moolah series has been expanded to include a variety of titles, such as Fortunium Gold , Mega Moolah Goddess and Absolootly Mad - the latter of which holds the record for the largest Mega Moolah jackpot ever won £ That monster win came just two weeks after a WowPot jackpot of £ But a world-record slots jackpot of £33 million was won in December on the appropriately named WowPot slot game Wheel of Wishes.

Whilst the aforementioned slots all contribute into shared jackpot pools, the following four slots are stand-alone games, each boasting its own progressive jackpot:. Below we've categorised the most popular themes and shared our personal favourites from each.

The world of animal-themed online slots can transport you to the North American plains, Amazonian jungles, the depths of the ocean, or simply feature your favourite pets. Part of the Big Bass series from Pragmatic Play, this slot offers engaging gameplay with clean artwork.

The free spin bonus round features a ladder trail with extra spins and an increasing multiplier for each unlocked level. Another great slot from Pragmatic Play and one of the earliest to feature the Megaways game mechanic.

The free spin bonus round presents a choice between Sticky Wilds or Raining Wilds, both with the potential for mega payouts. Blueprint Gaming and Microgaming lead the way for movie slots and this category could easily include another six or so exceptional games, but we've tasked Ana Dimitrijevic and the team with whittling it down to the Gambling.

com top three. Whether or not you're a fan of the Spielberg blockbusters, Microgaming's Jurassic Park slot is a real treat to play. Land three Amber scatters to choose between five exciting bonus rounds and look out for the T-Rex symbol, which triggers Alert Mode, adding 35 wilds to the reels for the next six spins.

No other game provider excels at creating adult cartoon-themed slots more than Blueprint; it's truly their forte. The mechanic of this game may seem familiar, but it is more than just a reskinned slot.

You get to choose from four fantastic bonus features: Pickle Rick Spins, Federation Wild Spins, Vindicator Spins and Mystery Spins, all with a potential maximum win of 50,x. While Pragmatic Play aren't typically known for licensed slots, they've nailed it with the Peaky Blinders slot.

With gritty character voice overs and random bonus features like The Shelby Betting Shop and By Order of the Peaky Blinders, this game perfectly recreates the atmosphere of the beloved West Midlands gangster series.

Such is its popularity, for some players there simply are no other types of online slots. Trigger the free spins bonus round to receive a 3x multiplier with the possibility of unlimited retriggers, while landing nine scatters wins you the jackpot.

Triggering the Cash Collect feature on reel 5 can lead to winning all cash prizes or activating the free spins bonus round. Plus, there are four Cash Collect fixed jackpots available, determined based on a multiplier of your stake.

The simple, yet charming appeal of clean graphics and an easy to achieve free spins bonus round makes this NetEnt classic a joy to play.
