Blueprint Gaming’s big ape has been stomping through online slot catalogues since 2016, and this Jackpot King edition bolts a three-tier progressive system onto the original King Kong Cash framework. The 5×3 grid runs 20 paylines through a jungle canopy that looks like it was pulled straight from a 90s platformer.
Kong sleeps on top of the reels, occasionally waking up to throw one of five random modifiers into the mix. Land three Bonus scatters and a wheel spins to select one of five distinct bonus games, from pick-and-match rounds to free spins with roaming wilds. The Jackpot King layer sits above all of it, feeding every qualifying bet across every connected game into three progressive pots that have historically climbed past £3 million.
Kong dozes above the reels during standard play and can wake up on any spin to trigger one of five random modifiers.
Three or more Bonus scatter symbols anywhere on the reels launch the Bonus Wheel. The wheel selects one of five bonus games at random, each with its own structure and payout profile.
The Jackpot King overlay can activate randomly on any spin. When it triggers, the game shifts to a separate screen where you spin to fill a trail of crown symbols. Completing the trail enters the Wheel King round, where three progressive pots are in play. The Royal Pot is the smallest and triggers most frequently. The Regal Pot sits in the middle. The Jackpot King pot is the headline prize and has been won at values exceeding £3 million. Every qualifying bet across all connected Jackpot King games feeds into these pots, so they grow continuously until someone wins.
The original King Kong Cash launched in 2016 with the same five bonus games and Sleepy Kong modifiers but without the progressive layer. This Jackpot King edition keeps the core game intact and adds the three-tier pot system on top. The series has expanded well beyond these two versions since then. King Kong Splash takes the character into a waterpark setting with a different feature set, while the Even Bigger Bananas branch pushes the max win ceiling higher with cascading reels and enhanced multipliers.
Blueprint Gaming has built Kong into one of the most recognised slot franchises in the UK market, with over ten variants released across the past decade. For something outside the Kong family, The Goonies brings a similar adventure tone to a different IP, and the long-running Fishin’ Frenzy series shows how Blueprint approaches franchise building with a completely different theme.

Twenty lines run across a five-reel, three-row layout — the same frame as the original King Kong Cash. Symbols match from the first reel rightward, and where two combinations share a line, the higher-value result is the one that pays. The Jackpot King progressive layer sits on top of this structure, capable of firing independently from any spin outcome.
The bet window is 0.10 to 200 per spin. The paytable scales dynamically with your selected stake. Medium volatility gives the session a more balanced rhythm than higher-variance games, though the reels can still run cold between features. The Monkey Modifiers break up those stretches by triggering randomly, and the five-way bonus split means the King Kong Bonus can play out very differently each time it lands.
The Wild symbol is the golden barrel stuffed with coins. It appears on all five reels and substitutes for every paying symbol except the Bonus scatter. The Barrel Wild and the KKC Logo share the top paytable position, both paying 25.00 at a 1.00 stake for five of a kind, with payouts starting from just two matching symbols on a line.
All amounts correspond to a 1.00 total wager and adjust in line with whatever bet you choose.
| Symbol | 5 of a Kind | 4 of a Kind | 3 of a Kind | 2 of a Kind |
|---|---|---|---|---|
| Barrel Wild | 25.00 | 5.00 | 2.00 | 0.10 |
| KKC Logo | 25.00 | 5.00 | 2.00 | 0.10 |
| Rhino / Tiger | 15.00 | 4.00 | 1.00 | — |
| Parrot / Croc | 10.00 | 3.00 | 0.50 | — |
| A / K | 5.00 | 2.00 | 0.40 | — |
| Q / J | 2.50 | 0.50 | 0.20 | — |
The game caps non-progressive wins at 50,000x your total bet or 250,000, whichever is reached first. The three Jackpot King progressive pots sit outside this cap and are paid in addition to any winnings from the bonus games or regular spins. The combined RTP, including jackpot contributions, is 95.50%, split across 95.01% from the game itself, 0.30% from jackpot returns, and 0.19% held in reserve.
King Kong Cash Jackpot King wraps five distinct bonus games, five random modifiers, and a three-tier progressive system around a medium-volatility 5×3 grid. The variety inside the King Kong Bonus keeps the feature game fresh across repeat triggers, and the Sleepy Kong modifiers inject enough random events to maintain engagement between scatters. Sound design lets the package down, and the hit rate outside features leaves stretches of silence between the action. The 50,000x cap on non-progressive wins provides a solid ceiling, while the Jackpot King pots add open-ended upside for players willing to accept the RTP trade-off. A well-stocked edition that trades session-level efficiency for progressive potential and feature variety.
The Donkey Kong Country comparison writes itself. Kong lounging on top of the reels, the jungle backdrop, the barrel wilds, and the cartoon animal companions across the paytable. Blueprint Gaming leaned into the platformer aesthetic hard, and it works. The art style has aged well for a game that first appeared in 2016, with chunky, expressive character designs that suit the lighthearted tone. The Jackpot King edition does not change the visuals at all. It simply adds the progressive overlay to the existing package.
What does not hold up as well is the sound design. There is no background soundtrack during regular spins. The silence is filled by a reel spin sound that grates after extended sessions. The contrast with games that set a mood before the first reel moves is noticeable. Kong’s snoring animations and the occasional modifier trigger break the monotony, but the audio package feels like it was an afterthought.
The reels between features are quiet in more ways than one. During our session, wins outside the bonus games were sparse and small. The Monkey Modifiers fired a handful of times, adding some life to the session. Banana Cannon Wilds dropped two extra wilds that connected a Rhino five of a kind, and a Golden Barrell Super Spin added 98 barrels that exploded, creating some new winning combos. Those moments carry the experience when the Bonus scatters are not cooperating.
The five-way bonus split is the heart of the game. Each of the King Kong Bonus games plays differently, and the variety is what keeps return visits interesting. Empire Free Spins with roaming wilds climbing the building is the most visually engaging, while Golden Kong Free Spins with its collected wilds and Super Spin finale has the strongest payout potential in a single round. Big Money Bonus is the swing round, where the wheel can land anywhere from modest returns to 1,000x. The randomness of the Bonus Wheel means you never choose your preferred game, which adds unpredictability that some players will enjoy and others will find frustrating.
The Jackpot King layer is the reason this version exists alongside the original. The three progressive pots give every spin a theoretical path to a huge payout. The Royal Pot triggers with enough regularity to feel achievable, and the top pot has historic wins above £3 million. Whether that upside justifies playing at a lower RTP of 95.01% compared to the non-progressive version at 95.80% depends on how much weight you give to the progressive chase versus session-level returns. The free play demo strips the progressive element out entirely, so treat it as a test of the base game and bonus variety only.
