Ever wondered how the Jackpot King feature really works, or how often it actually pays out?
This blog takes a closer look at what Jackpot King slot games are, how they operate, and the types of wins some people have seen over the years.
We’ll also explore how frequently the jackpot tends to be won, whether certain games are more likely to trigger it, and if your bet size makes any difference.
Whether you’re new to online slots or just curious about how the Jackpot King system works, this guide offers a clear and straightforward explanation.
How Jackpot King Works
Jackpot King is a progressive jackpot system linked across various online slot games. This means that instead of offering its own prize pot in just one game, it collects a small portion of bets from every connected game across the network. These games can sometimes be available across multiple online casinos, depending on the operator and the game provider’s configuration.
To activate the Jackpot King feature, you’ll need to trigger a specific in-game mechanic. Typically, this involves landing five Jackpot King overlay symbols during a spin. Once activated, you enter a bonus round with a chance to move through different stages: collecting crown symbols to climb up the ladder, reaching the Wheel King stage, and potentially spinning for one of the progressive jackpots – Royal, Regal or the main Jackpot King prize.
Jackpot King games are developed by Blueprint Gaming, and not all Blueprint slots offer this feature.
How Frequently Is Jackpot King Won?
There’s no fixed schedule for when the Jackpot King pot pays out. Like other progressive jackpots, it builds over time until one player triggers it through the bonus feature. This system is completely random and does not follow a set pattern.
Historically, Jackpot King has paid out several significant wins each year. However, the frequency can vary. Sometimes the pot grows for months before a win occurs. Other times, it may be won twice in a relatively short period. This is because the outcome is based on Random Number Generation (RNG), which ensures that every spin is unpredictable and independent of any previous outcomes.
The jackpot grows in real time across the linked games and resets after being won. If you're playing at a casino where the Jackpot King feature is available, you might see the jackpot totals rising as more players contribute.
What Was the Most Recent Jackpot King Win?
In October 2024, an accountant from North London became one of Betfred’s largest ever Jackpot King winners. She was playing the Deal or No Deal: Bankers Boost Jackpot King slot when she hit the main jackpot, walking away with £4.3 million from just a £2 spin. According to Betfred, it was her first attempt at playing online slots.
This is a clear example of how these jackpots can be won by anyone playing a linked Jackpot King game, regardless of prior experience or how long they’ve been playing.
Biggest Jackpot King Slots Winners List
Here are some notable Jackpot King winners from the UK and Europe:
-
October 2024: £4.3 million – Won by a Betfred player on Deal or No Deal: Bankers Boost with a £2 spin.
-
August 2024: £2.4 million – A player from Manchester won this amount from a £1 stake on a Jackpot King slot at Grosvenorcasinos.com.
-
January 2024: £5.7 million – A Paddy Power Games customer won this sum playing a Jackpot King Deluxe slot.
-
January 2023: £5.4 million – Michael Clark from Newcastle won on his mobile with a £1.40 stake.
-
April 2020: Approx. £7.1 million (€8.1 million) – A player on PokerStars Casino turned €0.80 on Deal or No Deal Megaways into the biggest jackpot of that year.
These examples show that the jackpot can be triggered with various stake sizes across different games. However, it’s important to understand that wins like these are extremely rare.
While these large jackpots are possible, the vast majority of players will never experience a win of this size. Progressive jackpots, such as Jackpot King, are designed to build over time and only pay out occasionally, often after many thousands—or even millions—of spins across the network.
The odds of triggering the jackpot feature, and then progressing through to win the main Jackpot King prize, are very low. This rarity is what allows the prize pool to grow to such high amounts.
If you choose to play Jackpot King slot games, it’s best to do so for entertainment, with the understanding that a jackpot win is not something that can be expected or predicted.
Can You Win Jackpot King on Any Slot Game?
No – only specific slot games come with the official Jackpot King progressive jackpot system built in. These games are typically developed by Blueprint Gaming, and not all of their titles offer this feature. You can check whether a game is part of the Jackpot King network by reviewing the game’s paytable or information screen before playing.

Do Certain Jackpot King Slots Pay Out More Often?
No, certain Jackpot King slots don’t pay out more often than others. There’s no official data to suggest that one game in the Jackpot King series is more likely to trigger a win than another. All Jackpot King slots that are linked to the same progressive jackpot contribute to the same prize pool, so the size of the jackpot and the chance of hitting it remain the same across those games.
Some players might feel that certain slots "seem" to pay out more, but this is purely down to personal experience or preference. Every Jackpot King game uses an RNG, which means each spin is completely random and not influenced by what’s happened before.
It’s also worth considering that some Jackpot King slots may feel different to play. Some are packed with features and bonus rounds, while others may be more straightforward. While this can affect your enjoyment, it doesn’t affect your chances of potentially winning the jackpot.
Always remember to play safely, set limits, and never chase losses. Slots should be fun, not a way to make money.
Does Your Bet Size Affect the Odds?
In many Jackpot King slot games, the bonus feature can be triggered on any bet size – whether you’re playing with a small stake or a larger one. This means that it's possible to win the main jackpot even when betting with a lower amount, as shown in some of the real-life winner examples.
The main Jackpot King prize is awarded at random. It’s not guaranteed and isn’t directly tied to how much you stake. All players, no matter their bet size, have a chance to trigger the jackpot feature – though this chance is low and entirely random.
It may be a good idea to read the game rules or paytable to understand exactly how the jackpot feature works for the slot you're playing, as mechanics can vary slightly from one game to another.
What Happens After a Jackpot King Slot Win?
When someone wins the Jackpot King progressive prize, the jackpot resets to a base amount, which varies depending on the game setup and provider configuration. All other players continue contributing to the jackpot as usual.
The winner is typically notified immediately within the game. If it’s a large amount, the casino may reach out directly to confirm their identity and arrange for secure payment. Depending on the site and the size of the win, it could be paid as a lump sum or in instalments – always check the terms and conditions of the casino you’re playing at, as these can vary.
Once the win has been confirmed and processed, the prize will usually appear in the player’s account balance.
Is Jackpot King Really Random or Is There a Pattern?
Jackpot King outcomes are generated by a certified RNG. This means every spin is independent and not influenced by any previous spins. There is no way to predict or manipulate the outcome.
This system is regulated by the UK Gambling Commission (UKGC) and must comply with strict fairness and transparency requirements.
The theoretical Return to Player (RTP) rate is also reviewed and published, although it’s important to remember that RTP is an average calculated over millions of spins – not a guarantee on any single session.
Any pattern or “hot streak” noticed by a player is coincidental and not based on how the game is programmed.
