King Kong Cash: Even Bigger Bananas 4 Slot Review
Blueprint Gaming’s King Kong Cash: Even Bigger Bananas 4 carries on the acclaimed series, but will it be the biggest yet?
In the world of entertainment, King Kong has become a staple figure. He’s a cinematic celebrity, famous for his daring ascent of the Empire State Building, swatting at planes and tragically falling to his death. He was a misunderstood figure, caught in a world he didn’t belong to, but the story of Kong in the world of Slots is a striking parallel.
Blueprint Gaming’s Kong is revered and well within his comfort zone as the king of the jungle. He’s concerned not with scooping up damsels and ascending New York skyscrapers – he’s quite happy to sit on his throne, have a snooze, scratch the occasional nut and of course, throw some barrels around.
King Kong Cash Even Bigger Bananas 4 offers up a lot of features, and an extended play session that few other slots possess, thanks to its trail unlocks.
King Kong Cash comes with 95%, 93% and 92% RTP configs, plus a max win of 10,000x the bet and medium volatility.

Base Game & Features
King Kong Cash Even Bigger Bananas 4 has a setup of 6 reels and 4 rows, delivering 4,096 ways to win.
Payouts are awarded when 2 to 6 premium symbols, or at least 3 of the lower-value ones, connect from left to right, starting from the leftmost reel.
The top prize comes from the Golden Kong symbol, which pays between 0.5x and 5x the total stake. Other symbols yield returns ranging from 0.4x to 2.5x your bet. Wilds can land on reels two through six, substituting for symbols except for the Scatter, Cash, and Collect symbols.

Our Honest Verdict
The Bigger Banana series has proved to be a long one, much further in fact than we thought it would ever be.
The series has inspired Blueprint to make similar offerings, including the latest branded slot, Dumb and Dumber Route to Riches, which featured not only an exact match as far as max win goes, but RTP too, with 95%, 93% and the dreaded 92% option.
If these games prove anything, it’s that there’s value in a game with longevity. The features aren’t open straight away, nor is the a chance to win the illustrious jackpot prizes, but it doesn’t take long to unlock them at all, and experiencing the upgrades as you go is actually quite enjoyable.
Like previous games, Cash Collects can be triggered in unison, making for an exciting spectacle as two (hopefully non-standard) Cash Collect symbols work their magic. One feature we’re particularly fond of is the Banana Blitz, which seemed to not only fill up fairly quickly, but also trigger often, too.
Within it is an array of exciting prizes, including more features, showcasing how diverse King Kong Cash: Even Bigger Bananas 4 really is.
All of this is even before you’ve experienced the multiple Free Spins rounds and the jackpot prize. Seemingly, its only drawback is the 10,000x cap. We feel like Blueprint could have lifted the lid here.
Other than that, their flagship IP hits once more. Kong is here to stay, and this may be one of the best ways to experience his majesty.
Playable now at Slot Sites in the UK and beyond, King Kong Cash: Even Bigger Bananas 4 is an exciting option.
