Slime Kingdom

Slime Kingdom is a fantasy, magic, medieval and humor themed slot from Splatworks with an RTP of 96.5%, high volatility and a maximum win of 15,000x. The game uses a 6×5 grid with 15,625 Bet Ways, creating multiple winning opportunities on each spin.

Cascading wins form the core of the gameplay: when symbols win, they burst and new ones fall from above and through the Feature Lane until the board settles with no further matches. Winning positions retain a multiplier that starts at x2 and doubles on each subsequent win at the same position, climbing to x128 maximum.

The FS Scatter triggers the bonus round. Three, four, five or six scatters award 5, 8, 10 or 12 Free Spins respectively after avalanches finish. If at least one scatter is a Royal Cauldron, the slot upgrades to Royal Free Spins instead, which features richer reels with more Wilds, premium symbols and +3 symbols. Five scatters on a Royal trigger start 10 Royal Free Spins immediately.

During Free Spins, multiplier cells persist across every spin and continue doubling to x128. Scatters landing in the bonus do not add extra spins; instead, retriggers depend on special feature symbols.

Several non-winning board states trigger features in order of priority. Slime Bomb clears its own position and every regular symbol in a 3×3 area, then doubles the multiplier of every position it touches. Splat Converter turns a 3×3 area into one selected regular symbol. Queen's Blessing converts selected regular symbols into Wilds, always converting at least one. Sticky Crown drops a locked Wild that persists through avalanches. Royal Decree, the final failsafe, converts an entire horizontal row into a single symbol already present on that row.

The crowned Queen Wild substitutes for all paying symbols except FS and feature symbols, and also pays as its own symbol.

Six bonus buy options let players start features directly: SLIME HUNT at 3x bet, GOO LAYER at 10x bet, Free Spins at 100x bet, MYSTERY SPINS at 128x bet, GRAND FREE SPINS at 150x bet, and Royal Free Spins at 200x bet.
