About this Slot
Slime Kingdom is a fantasy-themed slot with six reels, five rows and 15625 bet ways. The game has an RTP of 96.5%, high volatility and a maximum win of 15,000x.
The game features cascading wins on a Feature Lane that carries symbols right to left into play above the reels. Symbols arriving on the Feature Lane trigger features, scatters and bonus rounds. Multiplier cells start at x2 and double with each same-position win up to x128. These cells reset at the start of each paid spin but persist and continue doubling throughout Free Spins.
Three scatters award 5 free spins, four scatters award 8, five scatters award 10 and six scatters award 12. Landing a Royal Cauldron scatter upgrades the bonus to Royal Free Spins, which uses richer reels with more wilds and premium symbols.
Slime Bomb clears a position and its 3x3 surrounding area while doubling the multiplier of touched positions; it fires only when the settled board pays nothing. Splat Converter turns a 3x3 area into a single regular symbol type of the player's choice, but only if Slime Bomb is absent. Queen's Blessing converts at least one selected regular symbol into a wild and fires after higher-priority features fail. Sticky Crown drops a locked wild that stays through cascades and feeds multiple wins per round, firing when earlier features are not triggered. Royal Decree turns an entire row into a symbol from that row, triggering only if no other feature activates.
Buy options are available at SLIME HUNT (3x bet), GOO LAYER (10x bet), Free Spins (100x bet), MYSTERY SPINS (128x bet), GRAND FREE SPINS (150x bet) and Royal Free Spins (200x bet).
