Bonus features
Free spins
3, 4 or 5 Scatters anywhere award 5, 6 or 7 Butterfly Spins. Only Cocoon symbols land; active Cocoons turn into Butterflies, which move to the leftmost free position on their row and stay for the whole feature. Butterfly Spins cannot be retriggered.
Butterfly Re-Spins
When a stack of Butterflies covers a whole reel, the Butterflies move to the leftmost free spot on their row and lock while the rest re-spins. Each new Butterfly awards another re-spin until none land.
Butterfly Spins
3/4/5 Scatters award 5/6/7 free spins in which only Cocoons land and turn into sticky Butterflies.
Wild
The Lotus Flower wild appears anywhere in the base game and Re-Spins and substitutes for all symbols except Scatters.
In Butterfly Spins, only Cocoons land; each turns into a Butterfly that sticks to the leftmost free spot on its row and remains for the whole feature, building a growing cluster of locked symbols.
