The biggest jackpots and best jackpot slots

When most people think of UK casinos, the very first word that comes to mind is ‘jackpot’. A massive, life-changing sum awarded only rarely to lucky players. The term jackpot can be used to describe the win itself i.e. a sum of money that players win but today, it is often also used to describe the kind of game that offers such prizes.

Slot games are usually the kind of slot that awards jackpots, though there are a few other types out there. Our focus today is on helping you find the best jackpot slots to suit you.

Just like any slot game, the theme, mechanics and payouts of these games varies from one to the other but they have one thing in common – they are all progressive jackpots that have the potential to make multi-millionaires out of their players.

All of the jackpot slots we will be talking about today are progressive jackpots. This means that they continue to grow thanks to the ongoing wagers of players. To find out more about the different kinds of jackpots, head over to our in-depth jackpot guide for more information.

Mega Moolah jackpot slot from Microgaming

1. Mega Moolah – Microgaming

Mega Moolah is the granddaddy of jackpot slots at the moment and it’s easy to see why. This game, launched way back in 2006, has remained enormously appealing to players despite its age.

It has an RTP of 88.12%, which is about right for a progressive jackpot slot with such high payouts. Its volatility is considered to be within the medium range.

Informally known as the ‘millionaire maker’, Mega Moolah was where the world’s highest online jackpot win took place in 2015, with a £13.2 million payout changing one lucky British player’s life in an instant.

It has four jackpots in total – the Mini, Minor, Major and Mega jackpots – with the largest seeding at £1 million.

Hall of Gods slot from NetEnt

2. Hall of Gods – NetEnt

A mighty Viking clash sometimes ends in big wins for players in NetEnt’s Hall of Gods masterpiece of a jackpot. Launched in 2013, this game looks great, with detailed animation and design really bringing the gods of Norse myth to life.

Hall of Gods has a fairly high RTP for a game that offers a progressive jackpot, coming in at 95.5%. The presence of multiple jackpot possibility explains this percentage, as does its medium variance.

In other words, even if you don’t take home the big prize, this is still a good game to play if you are a more casual player and/or have a small budget.

Hall of Gods jackpot

Hall of Gods has three jackpots: the Mini, Midi and Mega jackpots, in order of ascending size. The game’s multiple bonus features make it an exciting one, even without the possibility of a massive win.

Mega Fortune jackpot slot from NetEnt

3. Mega Fortune – NetEnt

This slot game by NetEnt shows you all the things you could buy with a jackpot win – speedboats, jewels, expensive champagne, the works! Mega Fortune as launched in 2009, though having said that, we think its visual design has held up quite well over the 10+ years it’s been available.

Mega Fortune has an RTP value of 96.4% and low volatility, which adds up to a rewarding gameplay experience even if you don’t strike the big win.

One player in Finland held the record for the biggest online jackpot win for a while, thanks to a €17.8 million drop on Mega Fortune. The record has been beaten since then but we wouldn’t turn down a win that size any day!

On average the jackpot:

  • Is between £2 million and £4 million
  • Drops roughly every two months

Arabian Nights jackpot slot from NetEnt

Arabian Nights – NetEnt

Step into a sandy world of glittering jewels and bustling bazaars with NetEnt’s 2013 jackpot slot, Arabian Nights. This title is often overlooked in favour of bigger names like Mega Fortune and we think that’s a crying shame.

Arabian Nights showcases a creative theme, unlike the slots filled with symbols of wealth that can seem a bit flat. This game has an RTP of 95.6% and offers straightforward gameplay with multipliers and free spins to keep players entertained while keeping their fingers crossed for the big progressive jackpot.
