Does the prospect of hitting a million pounds from a single spin sound like something that you could get excited about? Well, let me introduce you to Jackpot King, a progressive jackpot system developed by Blueprint Gaming, but this isn’t just one game or slot you get to play; it’s a networked bonus engine that’s been built into dozens of the best games created by the UK-based studio, where every spin across participating casinos contributes a small percentage to three growing prize pots.
To help you understand and make sense of how it all works, from the Regal and Royal pots to the elusive Jackpot King itself, we’ve provided a full guide to help you along the way. We have everything you need, including a real-time tracker that shows the value of the current pots, a probability-based simulator that indicates your realistic chances of hitting a progressive, and free demo slots for each game in the franchise. So, strap in; we’re ready to show you what Jackpot King is all about.

How Jackpot King Slots Work
There’s really nothing to playing a Jackpot King slot. First, you’ll need to find a game in the Jackpot King progressive network at the online casino you’re playing at, which is usually marked or categorised under the jackpot tab. Once you’ve chosen the game you wish to play, select your stake and start spinning the reels; that’s how easy it is to join thousands of other players who are seeking that hit of a lifetime.
So, now we’ve taken the first step and entered into the pool of jackpot hunters; let’s break down the progressive system in more detail, explaining how it works, what triggers it, and what you can expect to see once the feature is activated.
How the Jackpot King Progressive Pots are Funded
Jackpot King versions of Blueprint slots tend to offer a return to player percentage between 93.02% and 94.75%, depending on the title. The reason they are lower than their non-jackpot counterparts is due to 0.65%–1.5% being used to seed and top up the progressive pots whist you are playing.
The Jackpot King network features a total of three progressive jackpots. Below we’ve created a table of these so you can see what they are and information about when they must be won.
| Pot | Payout | Must Drop Before |
| Regal | Frequent | €4,000) |
| Royal | Less Frequent | €40k) |
| Jackpot King | Rare | No cap |
What Are Must Drop Jackpots?
Developers are always looking for a way to drive more engagement into their jackpot slots, and Blueprint Gaming’s “Must Drop” progressive jackpots are a promise to players that the pots specified as this must pay out their value before they reach the target amount.

Triggering the Feature
The Jackpot King mechanic can be activated on any spin in the base game at random. You’ll know you’re in for a chance as the sound of the game changes slightly, and Jackpot King overlay symbols will typically appear along the centre line of the reels, starting from the leftmost reel first. If each position contains one of these special symbols, the bonus is triggered and you’ll move onto the next part of the feature.
The Crown Ladder
This is where the fun begins. The Crown Ladder part of Jackpot King is where you’re presented with a 5-reel, 4-row configuration that only contains crown and blank symbols. Each time a crown lands in view, you will climb one position up the meter and be granted another respin. If you fail to land 15 crowns, the bonus will end, and you’ll be awarded the corresponding multiplier from the meter, as seen in our table below. If, however, you hit the required 15, you’ll advance to the Wheel King.
| Crown Symbols | Prize |
|---|---|
| 5 Symbols | 5x Stake |
| 6 Symbols | 6x Stake |
| 7 Symbols | 7x Stake |
| 8 Symbols | 8x Stake |
| 9 Symbols | 9x Stake |
| 10 Symbols | 10x Stake |
| 11 Symbols | 12x Stake |
| 12 Symbols | 15x Stake |
| 13 Symbols | 18x Stake |
| 14 Symbols | 20x Stake |
| 15+ Symbols | Wheel King Bonus |
Wheel King
If you reach the Wheel King part of the bonus, you can begin to feel just a touch of excitement, as you are now at least in with a shot of hitting one of those progressives. As the wheel spins, you will see big multiplier values and the Royal, Regal, and Jackpot King segments spin by. As the wheel comes to a halt, whatever value stops across the markers is what you’ll be awarded with. Will you strike the jackpot? Fingers crossed.

Jackpot King Strategy & Playing Tips
Having a disciplined playing approach to Jackpot King is the best way to maximise your chances of triggering a bonus round and giving yourself a shot at hitting one of the three progressives. Our tips and strategy section will help to increase your win potential, so we’d recommend you consider each of the following points before playing.
Play at Low Stakes
Even playing at the smallest stakes qualifies you to trigger the Jackpot King feature and progress through to the Wheel King round, so make sure you don’t deplete your bankroll by spinning at higher stakes. Yes, you might be in with a greater chance at hitting the jackpot on bigger bets, but you don’t need to be playing at max stake, in fact, far from it, to hit one of the progressives.
Play Games With Added Features
The key to playing Jackpot King slots is to get as many spins through the game as possible to increase your chances of triggering the jackpot round, which is going to rely on you managing your bankroll correctly. This is why we suggest picking out games with extra features like free spins, hold-and-win bonuses, and even base game modifiers. Remember, the RTP taken for the jackpot is entirely separate, so the slot still has somewhere in the region of between 93.02% and 94.75% to pay out regular prizes. The more you can keep your playing balance elevated, the longer your session and the higher the possibility of activating that potentially lucrative Jackpot King feature.
Utilise the Demo Games
With a variety of themes to pick from and slots with varying levels of volatility, playing the games in a demo format first is the perfect way to see if you like them and what they can return in payouts. This tallies up with our previous tip of choosing the titles with extra features, as you can trigger them in the free play mode to see what they can reward.
Use Jackpot Trackers
By using Jackpot King trackers, like the one here at Demoslot, you can see when the top jackpot prize is above the average payout and when the Royal and Regal Pots are getting close to their “must pay” values. This, of course, isn’t going to guarantee a win, but if you want to maximise your chances of winning a progressive, you should play at the optimal time.
Jackpot King Simulator
We’ll always keep it real here at Demoslot and would never mislead our members and visitors into thinking that it’s easy or even frequent to land one of the progressive jackpot rounds. To give you an idea based on data that is publicly available, we’ve created a simulator tool where you can feed in your stake per spin, how many spins you’d expect to play through, and the RTP of the slot you’re playing. This will show you your expected cash return from the game and your chances, displayed as a percentage, of hitting one of the pots.
💡 While higher stakes may give you a slightly better chance of triggering the Jackpot King bonus, the jackpots themselves are not scaled by stake. That means even low-stake players can land the jackpot prize, and many have. As long as you meet the minimum bet (usually around €0.20), you’re in the running.

Top 5 Jackpot Games Ranked By Demoslot Rating
Demo & Review
Our Conclusion: Overall, I enjoyed elements of Slots O’ Gold, particularly the Rainbow Respin feature, which can provide high returns if you achieve several wild stacks with high multipliers connecting together. During testing, I was able to land three of these stacked wilds in a connecting win, which paid over 400x, so there is certainly potential there if you can manage to get all four out! I also appreciated that this slot pays both ways and that the pay values were fairly good, especially if you can win with the pot of gold symbol across all six reels. Slots O’ Gold is a fun little game to play for a short burst during a slot session. However, the lack of what I would classify as a proper bonus round and the monotonous sound effects means that this title does not do enough to rise above its abundant competition.

Our Conclusion:
Many slot fans from around the globe will instantly recognise that Gold Strike Bonanza is similar to a few games that are already out there on the market. The first of these is Blueprint's very own Fishin Frenzy series of slots, with the second being Pragmatic Play's Big Bass Bonanza slot.
This game is in essence a kind of hybrid of these two games, with the outcome being something that's playable but not likely to be a game you'll go back to again and again. That's just my opinion, though, so try out the free demo slot of Gold Strike Bonanza in the review above, and see if you think it's better than the variations that are already out there online.

Our Conclusion:
Vikings Fortune was another slot that Blueprint added the Jackpot King feature to, and this feature can randomly trigger on any spin. The game itself is fairly low-key as far as Blueprint slots go, and there really isn't too much action with modifiers and bonus rounds.
It is still quite an interesting game, and it will appeal to a number of players who don't like all of the flashing lights and hi-tech features that come with some slots these days. We recommend that you try it for free in our demo and see what you think of it, especially if you're looking to play it for the Jackpot King feature.
Demo & Review
Our Conclusion:
This is a fun variant of the Luck of the Irish franchise, but it doesn’t play like the original game, as wins are not awarded for sets of adjacent symbols appearing anywhere on the reel set. The fortune play mode is a highlight, and it’s worth checking this game out for that alone. Plus, it's part of the Jackpot King network, so if the luck of the Irish is with you, then you might just hit one of those three progressive pots.
Demo & Review
Our Conclusion: There are a good few versions of this slot with a £500 jackpot in many arcades around the UK, and I always have a few quid in one when I see them as they like to chuck out a free spins bonus regularly. In the land based version, a full screen of free spin symbols was almost guaranteed to be the jackpot, but this won't be the case online, although you can expect some handsome rewards coming your way if and when it does happen.To wrap this review up, I would say that if you've played the Bar-x machines over the years in the arcades, you'll undoubtedly enjoy the online version, too, but just be weary of how the gameplay can differ regarding win frequency.
Are There Any Alternatives to Jackpot King?
Having explored the Jackpot King collection of games, you may wish to try your luck elsewhere, and if that’s the case, we have some fantastic news, as there are many other options for you to try out. Two of our top recommendations are the Dream Drop jackpot slots from Relax Gaming and the Megapays progressive slots from Big Time Gaming. Alternatively, if you want to see the current values of all the jackpots we track here at Demoslot, you could head over to our progressive jackpots tracker page and see which real-time total you fancy taking a shot at.
Jackpot King Pros & Cons
Pros
- Players qualify for a chance to trigger the jackpot even when playing at the lowest stake.
- Blueprint has incorporated the Jackpot King progressive mechanic into many of its top games.
- Includes “must drop pots” so players can time when to start playing the games.
Cons
- The standard RTP of the games is below average due to the Jackpot King progressives sucking up some of the RTP.
- The progressives are very rare to hit.
- It can be frustrating when you trigger the feature but don’t make it to the Wheel King part of the bonus.
Final Thoughts
Obviously, the chances of winning a progressive pot on Jackpot King are relatively slim, requiring a significant amount of luck to land one. However, with the Jackpot King mechanic continually being added to more of the Blueprint games slot catalogue, it could be considered a no-brainer to play a version that includes this progressive network because you never know if it might be your day! It could also be the slot romantic coming out in us, but we just love that somebody depositing a very small amount of money and playing at a very low stake could change their entire life with just one spin.
Jackpot King FAQ
No. One of Jackpot King’s most appealing features is that you can qualify for the jackpots with stakes as low as €0.20. Higher stakes don’t guarantee better chances; the jackpot triggers randomly on any spin regardless of the bet size.
These indicators show how close a jackpot is to its typical payout point based on historic averages. **Cold:** The pot is still well below its usual win range. **Hot:** The pot is getting close to where it usually drops. **Boiling Hot:** Historically due to drop soon. This heat system helps players track pot volatility in real time.
Some Jackpot King pots, like Regal or Royal, are set to drop before reaching a certain value. These “must-drop” thresholds are based on fixed values set by Blueprint, giving players a better idea of when a jackpot is likely to hit.
The Jackpot King top prize is rare and has no fixed drop point. On average, based on historic data, it drops somewhere between €1.3M and €3.5M, though it can go higher.
No. The Jackpot King feature can be triggered on any base spin. Bonus rounds, scatter wins, or wilds have no impact on your jackpot odds.
All Jackpot King slots share the same underlying jackpot mechanic. However, some titles like Fishin’ Frenzy Jackpot King or Irish Riches Megaways may offer faster gameplay or better hit rates, which can make it feel more active.
