Jackpot King is a progressive jackpot system developed by Blueprint Gaming. It connects a range of slot games, allowing players across different titles to contribute to—and potentially win—the same growing jackpot.
Each time a player places a bet on a Jackpot King game, a small portion of that wager is added to the jackpot pool. As more bets are placed, the prize fund continues to increase until it is eventually won. Once the jackpot is claimed, it resets to a fixed starting amount, and the process begins again.
The system includes three tiers of progressive jackpots:
While both the Regal and Royal pots have maximum payout limits, the main Jackpot King has no upper cap, which may make it more appealing to players interested in the chance of winning a large payout.
The Jackpot King feature can be triggered at random during any spin in participating games. This happens when five Jackpot King symbols land on the reels, activating a bonus round where players have a chance to try to win one of the three jackpots.
Yes—several players have won payouts from the Jackpot King system since its introduction. While many winners have chosen to remain anonymous, a number of notable payouts have been publicly reported.
One of the most significant took place in April 2021, when a player at PokerStars Casino received a jackpot of €8,133,445.23 (approximately £7.19 million at the time) from a €0.80 stake on Deal or No Deal Megaways. This remains the largest amount awarded through Blueprint Gaming’s progressive jackpot network.
Since then, other games connected to the Jackpot King system—including titles such as The Pig Wizard and King Kong Cashpots—have also recorded large payouts.
Because many players choose to remain anonymous, the identity of the most recent Jackpot King winner and the exact amount won are often not publicly disclosed.
As mentioned earlier, the largest publicly reported win remains the jackpot won by a player at PokerStars Casino on 30 April 2021, who received €8,133,445.23 (approximately £7.19 million) from a €0.80 stake on Deal or No Deal Megaways.
Other notable wins include a Jackpot King prize from The Pig Wizard, which awarded £3.17 million to a Sky Vegas player, believed to have occurred around 2017. While these are the most well-known cases, it is likely that additional jackpots have been won more recently but have not been publicly announced.

The Jackpot King progressive jackpot does not follow a set schedule and cannot be predicted. This is because slot outcomes are determined by a Random Number Generator (RNG), which ensures that each spin is entirely random and independent of previous results.
While there is no guaranteed pattern, industry estimates suggest that jackpots of this kind are typically awarded roughly once every 50 million spins. However, this figure is only an approximate average and can vary significantly based on factors such as the number of active players, the specific games involved, and betting behaviour.
Therefore, the jackpot could theoretically be won at any time, regardless of the stake size or how long the jackpot has been accumulating.
Jackpot King Deluxe is an enhanced version of Blueprint Gaming’s progressive jackpot system that retains the three tiers—Royal Pot, Regal Pot (both “must-be-won” by specific thresholds), and the uncapped main Jackpot King—but adjusts the mechanics to increase the frequency with which the capped jackpots (Royal and Regal) are won.
Popular Deluxe titles include Genie Jackpots, Eye of Horus, and The Goonies Return. These games typically feature a bonus called “Wheel King,” triggered by collecting enough Deluxe symbols, which gives players the chance to try to win multipliers or one of the three jackpots.
While exact records of Deluxe jackpot winners are limited, gaming news sources have reported the progressive jackpot pool occasionally surpassing £2 million. The Royal and Regal pots usually reset after reaching approximately £3,500 and £35,000, respectively, indicating that these smaller jackpots may be paid out relatively frequently. These values can vary slightly between games and operators.
If you’re playing a Jackpot King slot game, the jackpot feature can be triggered randomly during any spin—regardless of the size of your bet. These games are all linked to the same progressive system, meaning each spin contributes a small amount to the overall prize pool.
To activate the Jackpot King feature, you’d need to land five Jackpot King symbols during the base game. This triggers a special bonus round with its own set of reels and prize opportunities.
Here’s how the feature typically works:
It’s important to remember that triggering the Wheel King does not guarantee a jackpot win. These features are random, and like all slots, the outcomes are governed by an RNG, ensuring fairness and unpredictability.
Gambling should be viewed as a form of entertainment, not a way to make money. If you choose to play, please do so responsibly, stay within your limits, and never wager more than you are willing to lose.
