Jackpot Slots

Jackpot slots are more than they appear. They may look like your average UK casino game and be played similarly, but they present the possibility of winning a huge prize. You could win thousands of pounds when playing some of your favourite slots. Like The Pig Wizard, there's plenty of choices if you're looking for the most epic jackpot slots. Gaming giants Blueprint even offer their own range of jackpot slots, so each time you spin the reels of Genie Jackpots, Winstar slot and more, you could be in with the chance of winning an incredible sum.

How do jackpot slots work?

The way the jackpot is won depends on the type of jackpot available, but both jackpots available at 21.co.uk work on the same premise. Each time a stake is placed in a jackpot slot, a percentage of this stake will be added to the progressive pot until the jackpot is won. This is how the jackpot grows to be more and more valuable over time. When a jackpot is won, the progressive pot value will reset and the process begins again. The size of the prize available will vary from slot to slot, as this is dependent on how many people have played it thus far. The available jackpot prize will be displayed on the game's thumbnail, so you can use this to decide which of our jackpot slots to play. Jackpots are triggered at random, so there's no guarantee that you will trigger it, and no one knows when it will be awarded. At 21.co.uk online casino, there is an excellent collection of different jackpot slots to play, and we release new titles month on month, so keep checking back.

Jackpot King Progressive

When you think about jackpot slots, your mind probably turns to the Jackpot King Progressive with slots like Paws of Fury. This popular prize has become famous for awarding huge cash sums, and many of our slots are plugged into the progressive pot. The Jackpot King is triggered randomly by any spin at any stake and is split into three different stages. So what can you expect if you're the lucky player who triggers the Jackpot King Progressive? The first stage isn't too dissimilar to standard play, except you're spinning the reels for golden crown symbols. The more crowns you collect, the further you'll progress through the Cash Trail, which is the second stage of the Jackpot King Progressive. The Wheel King awaits those who make it to the end of the trail. Spin this tombola-style wheel for huge multipliers and the chance to win the progressive pot. 0.13% of every amount staked on your chosen jackpot slot is added to a reserve pot. When the jackpot is won, the progressive pot will reset to the reserve pot value. The jackpot begins with a seed amount, which funds the prize’s original amount, meaning the pot is never completely empty. 0.86% of each stake placed is then added to the progressive pot. The remaining 0.13% is given to the reserve pot.

How to win the Jackpot King

You can play on some of our top slots and the jackpot will just keep rising until a player lands the correct symbols to trigger the jackpot. To win the Jackpot King Progressive Jackpot, you'll need to enter the Jackpot King Bonus Round. Find five Golden Crowns on the reels after any spin, and the bonus round will begin. You'll then be shown the Super Reels, where you'll have to find even more Golden Crowns. The more Golden Crowns you find, the higher up the Cash Trail you will go, taking you closer to the Wheel King Bonus. Along the way, you'll also find pieces of the King's Treasure, which will give you cash prizes, or even Free Spins. When you reach the top of the Cash Trail, you'll begin the Wheel King Bonus. Here, you will spin the wheel to win up to a 1000x multiplier, or who knows, you might even win the jackpot itself!
