Comparasino sits down with Blueprint Gaming’s Daniel Kalinowski to get the lowdown on progressive jackpot slots and how they deliver life-changing payouts.
If you’ve ever played a progressive jackpot slot you’ll know just how thrilling and exciting each spin can be. With each spin, you see the jackpot grow in size and you never know if your next spin will be the one to trigger it.
In some cases, progressive slot jackpots can reach millions of pounds before they are won making them among the most popular type of slot game at online casinos.
But have you ever wondered how these progressive jackpots actually work or if there is anything you can do to improve your chances of winning? We have, and that’s why we sat down with Daniel Kalinowski, Blueprint Gaming’s Affiliate and Social Media Manager.
Daniel knows all about Blueprint Gaming’s iconic Jackpot King system, making him something of an expert on progressive jackpot slots.
Take it away, Daniel.
What is a progressive jackpot? How does it actually work?
A progressive jackpot offers slightly more dynamic mechanics than a fixed jackpot, increasing each time a particular game is played but not won. A percentage of every bet wagered is put towards the jackpot, called contributions, which continue to grow until a fortunate player wins the total value. When this happens, the jackpot resets to a seed amount and the process starts over. As progressive jackpots are linked across multiple jackpot-themed games, the total sum can climb to huge amounts as it has players from across the world contributing.
How do progressive jackpots trigger? Can you explain each trigger?
With regards to Blueprint’s progressive Jackpot King system, the pot is linked across multiple Jackpot King titles and so the pool is shared. We have three different progressive jackpots that are increased by every bet placed by players on these titles – Royal, Regal and Jackpot King, with the latter being the highest. The player can trigger this feature on any spin, regardless of their bet size. To do this, you must land five Crown symbols on your reel which will unlock the feature.
Once the Jackpot King bonus is triggered, players enter a mode where they will be collecting Crowns to move up the prize ladder where the main offering is the Wheel King feature. This is where players will spin for the last time to see whether they will win any of the jackpots on offer or other lavish cash prizes.

What makes your Jackpot King system so special?
At Blueprint Gaming we always try to innovate new game mechanics to enhance player engagement while providing that strong value securely. The Jackpot King progressive system is designed to ensure regular payouts to our players, and looking at the average bets placed on our Jackpot King titles that have been won, we believe we consistently deliver on these grounds! Since Jackpot King was released back in 2017, we have made 29 players into millionaires with over £190 million paid out via different pot win sizes across over 60 titles with the Jackpot King system in the UK.
Can players increase the chance of winning a jackpot when playing your game?
How often the Jackpot King is triggered depends on the volume of games hosted on our online casino operator’s platforms and their own configurations. All Jackpot King games share the same pool on the platform the player is on, and the jackpots are designed to be won before they reach a certain point, so this all depends on the number of games and players on a particular casino site. As mentioned in the previous question, we have made 29 players into millionaires since the progressive system was launched, with the latest being just last month (October 2024) when a fortunate Betfred player landed a whopping £4m from just a £2 stake.
What’s the biggest jackpot prize you’ve paid out to date?
That would be a grand total of €8,133,445.23 via Deal or No Deal™ The Big Hit Megaways™ Jackpot King back in 2021. The fact that this is complemented by our most recent winner from the same Deal or No Deal™ Jackpot King series highlights its frequent win potential and the genuine jackpot opportunities that are provided for players!
How do you work the progressive jackpot into games such as your latest release, Deal or No Deal™: Banker’s Boost?
When producing Jackpot King titles, meticulous research takes place as well as the assessment of player behavioural habits based on our analytics. Our Deal or No Deal™ collection of games has consistently performed strongly, a firm favourite amongst our player base and following the huge success of the original Deal or No Deal™ title, it felt right to refresh the series with a Jackpot King-led offering via Deal or No Deal™: Banker’s Boost.

If players haven’t experienced progressive jackpot slots, why should they take one for a spin?
Blueprint’s Jackpot King was one of the first progressive systems launched in the online sector and continues to be enjoyed by players globally. We maintain a diverse selection of games across which players can choose from, and all share the same big win potential. The fact the series continues to hit the headlines isn’t by chance – we grow and develop it, maintaining its appeal by introducing new titles such as Deal or No Deal™: Banker’s Boost.
We’re constantly monitoring which of our games can join the Jackpot King family, as well as identifying new, fresh ways we can update gameplay and overall appearance. Our Jackpot King series is a key asset for Blueprint Gaming and as long as players yearn for those life-changing dream wins, we’ll keep making it possible.
