Kingdom Below (Play'n Go) Slot Review

Kingdom Below: Slot Overview 

Play’n GO has been known to tap into all sorts of themes, and with Kingdom Below, they’ve swapped the calm seas of traditional fishing slots for a far more infernal setting. Forget the beardy fisherman pulling cash from the sea – this time, you’ll be descending into a lava-lit underworld where a floating demonic beast helps collect prizes amid flames, chains, and chaos. It’s a fiery take on the popular “money symbol collection” formula seen in games like Big Bass Bonanza or Fishin’ Frenzy, but this one definitely adds heat – literally and figuratively. 

Visually and structurally, this 5-reel, 4-row slot with 12 paylines carries Play’n GO’s trademark polish and accessibility. The gameplay is built around dynamic cash collection mechanics, random modifiers, and a smartly layered free spins round that builds as it progresses. With a top win potential of 6,000x the bet and a 96.25% RTP, Kingdom Below provides the volatility and features high-stakes players look for – even if your odds of hitting that top prize sit at a staggering 1 in 868,685,581.

Design and Graphics 

Kingdom Below trades traditional blue oceans for molten red canyons. The reels are framed in chains and pillars dripping with lava, flanked by rocky cliffs and scorched terrain. It’s a devilishly creative take that successfully distances the game from its ocean-themed relatives. Symbols include flaming versions of playing card icons (10–A), flaming weapons, and mysterious trinkets like a fiery trident and crown, all well-detailed and thematic. The highlight, visually speaking, is the floating Beast that hovers above the reels. Its presence adds tension and anticipation, especially when it swoops down to trigger one of the special cash collection features. The design leans into comic book-style menace rather than full-on horror, making it dark but approachable.

Gameplay Mechanics 

At its core, Kingdom Below is a straightforward slot with several layered mechanics that build upon the cash symbol collection model. Players land wins by aligning three or more matching symbols from left to right on one of the 12 paylines. There are no wild symbols in this game – a surprising twist, though one that’s ultimately compensated for by the robust free spins and grab mechanics. 

The flaming Beast is central to gameplay. On any base game spin, it can activate to trigger one of three grab-style features: 

Grab Feature: Collects all cash prizes on the reels. 

Slide n Grab: Collects all prizes and applies a multiplier based on the number of reels that contained them. 

Under Reel: A mystery prize is pulled from beneath a reel – this could be a cash prize, dud, or a free spin retrigger icon. 

These features trigger randomly, but often enough to keep you engaged. While it’s not the most interactive element, seeing the Beast float across the reels with malicious intent adds a lot of suspense.

Sound and Music 

The audio is dramatic and theatrical, leaning more toward fantasy-adventure than demonic horror. The music swells and pulses with energy, particularly during features. There are subtle ambient touches – distant echoes, metallic clinks, and ominous growls – that build tension during regular spins. When the Beast triggers a feature or the free spins begin, the soundtrack shifts into high gear with satisfying thuds and roars. 

All of this helps distinguish Kingdom Below from other, more laid-back cash collection slots. The atmosphere supports the theme excellently, immersing players in the depths of Play’n GO’s fiery underworld.

Bonus Features 

This is where Kingdom Below really spreads its wings – or flames. The slot’s primary bonus is a Free Spins round triggered by landing 3 or more scatter symbols. Once activated, you’re awarded 10 free spins and asked to “Pick a Fire,” choosing one of eight modifiers (which can appear in standard or upgraded forms). Regular Modifiers include: 

+5 free spins 

More grab symbols 

More grab triggers 

Slide n Grab triggers 

Lowest pay symbol removal 

Sticky grab symbols (for 1 spin) 

Upgraded Modifiers add even more punch: 

+10 free spins 

Higher multipliers (up to 5x) 

More symbols removed 

Up to 2 sticky symbols on every spin 

Only four modifiers can be active at a time. During the free spins, a progress trail also comes into play. Collecting scatter symbols progresses you along a 12-step trail, where reaching certain positions awards: 

Extra modifiers (steps 2, 6, and 10) 

+10 free spins (steps 4, 8, 12) 

Multipliers of 2x, 3x, and 10x for grab wins (applied at each milestone) 

You can reach a maximum of 50 free spins in total. It’s a rewarding system that grows more intense the longer you survive, and it really makes each spin feel like it’s building toward something.

Betting Options and Payouts 

Bets range from €0.10 to €50 per spin, making the game suitable for low-stakes explorers and high-rolling adventurers alike. The max win potential sits at 6,000x, which is solid, though not chart-topping, especially with such a rare hit frequency. 

Payouts from symbols are respectable: 

Low-paying 10-A royals award up to 10x the bet for 5 of a kind. 

Premiums like the flaming trident, sword, and crown pay 50x to 200x for a full line. 

Cash prizes in grab symbols range from 1x to 50x, and you can hit combinations that skyrocket when paired with modifiers and multipliers. 

It’s worth noting again that there are no wilds, which slightly affects regular spin value. Instead, the focus is fully on the collection mechanics and the high-risk, high-reward free spins mode.

Conclusion 

Kingdom Below is Play’n GO’s attempt to bring something a little spicier to the cash collection genre – and for the most part, it works. The demonic setting, flaming visuals, and the inclusion of a floating beast that randomly triggers collection features keep things interesting during the base game, while the free spins round is where everything comes together. 

With layered modifiers, multipliers, and a collection trail that mimics a mini progression system, the free spins round is a highlight – and feels far more dynamic than most of the genre’s competition. That said, the absence of wilds, the slightly hands-off Beast mechanic, and the incredibly slim odds of hitting the 6,000x max win may leave high-volatility chasers a little cold. 

Still, Kingdom Below brings enough new ideas to the fiery table to feel like more than just a clone. For those who enjoy the format but are burnt out on fisherman and fish, this devilishly designed slot might be just what the underworld ordered.
