About this Slot
Sporefall is a fantasy nature slot from Big Ducking Wings with an RTP of 96.7%, high volatility and a maximum win of 25,000x. The game uses seven reels and seven rows with Cluster Pays mechanics.
Matching clusters of symbols trigger cascades, where winning combinations collapse and new symbols drop to fill empty spaces. Spores grow into mushrooms; four merged mushrooms combine into a Giant Mushroom. Larger mushroom squares can merge again into 3x3 and then 4x4 formations.
The Root Wild substitutes all high and low symbols. Once per cascade, the Root Wild upgrades four neighbouring cells.
Puffballs pop after each cascade, clearing a 3x3 area around each one. Cleared cells are pushed one step forward by Puffballs.
Fireflies add +2, +3, +5 or +10 to the biggest mushroom on the board. If no mushroom exists, Fireflies convert a spore into a mushroom.
The Glow Jar multiplier begins at x1 and increases with each cascade during the bonus round.
Spore Season triggers with three Spore Pods and awards nine free spins. A forest floor persists throughout the Spore Season bonus round.
Puffball Storm triggers with four Spore Pods and awards eight free spins. During Puffball Storm, one to three Puffballs drop per spin.
Overgrowth triggers with five Spore Pods and awards ten free spins. The board expands to 9x9 during Overgrowth. Brambles lock the edges, and a Giant Mushroom starts at the centre. A Growth Meter opens the board sides one by one, with every cell stepping up as the meter fills.
Double Chance costs twice the standard bet per spin and increases Spore Pod trigger frequency. Double Chance remains active until manually switched off.
