Kingdom Below is set in a fiery underworld, presenting a hellish landscape with a playful twist. The game's background depicts a lava-filled abyss, with chains and rocky formations framing the reels. Despite the infernal setting, Play'n GO has opted for a lighter tone, featuring a cute demon as the main character. This floating Beast hovers above the reels, wielding a trident and playing a crucial role in the game's mechanics.
The slot's symbols include lower-value flaming stone card ranks (10-A) and higher-value themed icons such as flaming swords, rings, tridents, and crowns. The overall design strikes a balance between the ominous underworld theme and a more lighthearted, cartoon-like aesthetic.
While Kingdom Below doesn't appear to be part of an established series, it shares similarities with popular “cash collect” style slots. The game's mechanics bear resemblance to titles like Pragmatic Play's Big Bass Bonanza and Blueprint Gaming's Fishin' Frenzy series. However, Play'n GO has given the concept a fresh spin by swapping the typical fishing theme for an underworld setting.
Core Game and Mechanics
Kingdom Below features a 5×4 reel layout with 12 paylines. Wins are formed by landing matching symbols on adjacent reels, starting from the leftmost reel. The game's volatility is rated 7 out of 10, indicating a medium-high risk level.
A key mechanic is the cash collect system, represented by “Grab symbols” or “Cash Grab Prizes.” These symbols can appear on the reels with values ranging from 1x to 50x the bet. The floating Beast character is central to collecting these prizes.
The base game is enhanced by the Floating Beast Feature, which can trigger randomly. When activated, it can initiate one of three effects: the Grab Feature, Slide n Grab, or Under Reel Feature.

An interesting feature of Kingdom Below is its progressive Free Spins round, which combines elements of choice (Pick a Fire Feature) with an escalating reward system (Scatter collection trail). This creates a dynamic bonus experience that can potentially lead to substantial wins, especially with the increasing multipliers and additional modifiers.
