Game Overview
Kingdom Below from Play’n GO ventures into the dark realms beneath the mortal world, where ancient powers rule and lost souls wander eternally. This high-volatility slot delivers a gothic masterpiece with sophisticated mechanics that expand the playing field and offer exceptional maximum win potential.
Starting with a 5x3 grid and 243 ways to win, Kingdom Below features an innovative expanding reel system that can increase the grid to 5x7 during bonus features, dramatically increasing ways to win to over 16,000. The dark fantasy theme is executed with stunning artistry, creating an atmospheric journey through shadowy kingdoms where substantial rewards await brave players.
Gameplay Mechanics
243 Ways to Win System
Instead of traditional paylines, Kingdom Below uses a ways-to-win mechanic where symbols on adjacent reels from left to right create winning combinations. The base 5x3 grid provides 243 ways to win, already offering more winning potential than most payline slots.
High-value symbols include shadowy demon lords, cursed artifacts, and dark royalty figures rendered in intricate gothic detail. The wild symbol (underworld gate) substitutes for all regular symbols except scatters.
Soul Collector Feature
During base gameplay, special soul symbols can appear. When they land:
- Soul values are collected (ranging from 2x to 50x bet)
- Multiple souls accumulate during the triggering spin
- Total value awarded when collection ends
- Can trigger randomly or through specific symbol combinations
This feature adds unpredictability to the base game, creating sudden windfall moments between bonus triggers.
Random Multiplier Wilds
Wild symbols can land with attached multipliers ranging from 2x to 10x. When multiple multiplier wilds contribute to the same winning combination, their values multiply together rather than add, creating exponential growth potential.
Underworld Spins Feature
Triggering the Feature
Land 3 or more scatter symbols (demonic portal) anywhere on the reels to trigger Underworld Spins:
- 3 scatters - 10 underworld spins
- 4 scatters - 15 underworld spins
- 5 scatters - 25 underworld spins
Expanding Reel System
The Underworld Spins feature introduces a revolutionary expanding reel mechanic:
Progressive Expansion
- Feature begins on standard 5x3 grid (243 ways)
- Each winning spin adds one row to the grid
- Grid can expand up to 5x7 configuration
- Maximum grid provides 16,807 ways to win
- Grid size persists for remaining spins
Strategic Depth The expanding system creates a strategic dynamic - consecutive wins early in the feature establish a larger playing field for remaining spins, dramatically increasing winning potential for the rest of the bonus round.
Enhanced Features During Underworld Spins
Increased Soul Values Soul Collector symbols during Underworld Spins display values from 5x to 100x (doubled from base game).
Guaranteed Multiplier Wilds All wild symbols that land include multipliers, with values ranging from 2x to 15x during the feature.
Persistent Grid Expansion Once the grid expands, it maintains that size for the duration of Underworld Spins, meaning a single early expansion benefits all subsequent spins.
Retrigger Mechanics Landing 3+ scatters during Underworld Spins awards additional spins AND adds an extra row to the grid immediately, even if already at maximum size (in this case, it adds a multiplier to remaining spins).
Visual Design & Dark Atmosphere
Gothic Masterpiece
Kingdom Below features some of Play’n GO’s finest artistic work, with a dark, atmospheric aesthetic that rivals AAA video game production values. The underworld realm is rendered in deep purples, blacks, and fiery oranges, with ancient stone architecture, floating ruins, and ethereal mist effects.
Symbol designs are intricate and detailed, with demon lords featuring elaborate armor and cursed artifacts glowing with dark energy. Animations are smooth and cinematic, particularly during the Underworld Spins trigger where the camera descends into the depths of the kingdom.
Haunting Orchestral Score
The audio design features a full orchestral soundtrack with haunting choirs, dramatic string sections, and ominous low-frequency tones. The music builds intensity during feature triggers and winning sequences. Sound effects include echoing whispers, demon roars, and mystical energy pulses that enhance the dark fantasy atmosphere.
