In Search Of The Elusive Progressive Jackpot: Find Them At Sky Casino, Bet365 Vegas And Coral Casino

Over the past few weeks we have taken a look at three different slots available on our ISM partner sites, Mega Moolah, Marvel’s range of slot games and the fantastic Monty Python-based Spamalot slot.

One thing links these and many other slots that grace the sites of our partners on ISM and that is that each of these games is a progressive jackpot slot - a slot that offers players the chance to win a life-changing amount of money all for the spin of the reels.

Yet the three progressive jackpot slots we’ve reviewed recently is only the tip of the iceberg of what has become one of the key areas of online gaming for slots players. Progressive jackpot slots are now amongst the most popular slots played online, both via a PC and via a mobile and as a result there are an increasing number of options available  

In this article, we are going to learn about some of the other top progressive slots you can play at some of our partner casinos, but first we’re going to learn about what a progressive jackpot is, how it is funded and why they are so popular with slots players around the world.

What is a progressive jackpot slot?

A progressive jackpot slot is a slot game that in addition to having the usual prize funds for landing a winning combination of symbols across the reels that pay out a stated amount, also has a top jackpot prize which can be won, albeit rarely compared to the other types of win available on the game.

Over time and as more people play the slot, the progressive prize fund increases and given that it is rare for the fund to be triggered, some progressive prizes can reach hundreds of thousands, or even millions of pounds/dollars.

The progressive jackpot is triggered only when a rare winning combination appears across the reels, or the player achieves something special in a bonus game allied to the slot. For example, to trigger the progressive jackpot in the Major Millions slot, you need to land all five Major Millions symbols in each of the five slot positions on the 15^th payline.

The term progressive simply indicates that over time, the size of the prize can increase as more players play the game and the fund grows as a result.

How is a progressive jackpot prize funded?

Usually most progressive jackpots are seeded by the host casino with a stated amount of money. Mega Moolah for example, is seeded every time the jackpot is won with a $1m cash injection from its owners. Other progressive slots may be seeded with varying amounts of money from just a few pounds, up to a million or more.

After the fund has been seeded by the casino, it is then added to when players play the game and spend real cash doing so. For every real cash spin, a small percentage of the players stake money is added to the progressive jackpot fund. So for example, if a player spends £1 on a spin on a progressive game, 90p may go on paying out regular prizes on the slot, 5p may be the casinos profit and 5p may be added to the progressive fund.

Progressive funds grow so large because of the number of spins each player plays but also because the number of players who play the game. Given that an online slot can be available at hundreds of casinos, with hundreds of players at each casino playing the same slot each day, this can rapidly accelerate how much is added to the progressive prize.

Why are they so popular?

Progressive jackpot slots are so popular as they offer users a very slim chance of winning a life-changing amount of money on a single spin of the reels. Those chances may be very very small, but it is still there and that is what drives people to play.

It is a similar appeal to National Lottery type games, where players only have a very slim chance of winning the jackpot, but still flock to participate every week.

Is it true that if a progressive jackpot is won, it will not be won again for a considerable amount of time?

No, this is an example of a gamblers fallacy.

In truth, every player who pays for a turn on a progressive game has the same chance of winning the jackpot whether the jackpot was won, one spin, one week, one month, one year or a decade ago.

This was demonstrated on the Mega Moolah slot which saw over a year pass between the first two winners (April 2025 to May 2025) but then in 2025, there was a winner every month from September through to December.

One last tip for UK progressive jackpot slots players

One final tip before you head off to play some of these high quality progressive games, is that it is worth checking whether a slot has a minimum bet threshold at which the progressive jackpot becomes available.

On some of the slots listed above, you do have to wager a certain amount in order to be eligible to win the top progressive prize.
