Butterfly Blossom Slot by PG Soft

Caterpillar Wilds land on the three center reels and survive exactly as long as they keep winning. If a Caterpillar participates in a cascade win, it sticks in place and transforms into a Cocoon. Another win with the Cocoon, and it becomes a Butterfly. One more win after that, and the Butterfly adds +5 to the highest multiplier tier before it disappears. Miss a win at any stage and the wild is gone. So getting a wild through all three forms requires three consecutive cascade wins involving that same position - a narrow path that the game's 20 paylines and sticky behavior are built to support.

Cascades run a four-step multiplier in the base game: x1 on the first win, x2 on the second, x3 on the third, x5 on everything after. It resets each new spin. The multiplier and the wild evolution run in parallel, which means a Butterfly completing its cycle on the fourth cascade hits at x5. Multiple Caterpillars can land on the same spin across reels 2, 3, and 4, each evolving independently. If two reach Butterfly stage on the same cascade chain, both dump +5 into the multiplier tier.

Purple flowering branches curl around the reels against a soft-focus garden backdrop, with petals drifting across the grid between spins. The Caterpillar symbol is bright green and cartoonish, the Cocoon a glowing golden pod, and the Butterfly a luminous eight-winged creature in violet and amber. Regular symbols are gemstone-cut card royals and stylized flower icons, all sitting on translucent reel strips that let the garden show through.

Free spins trigger at 3 scatters for 8 spins, with +2 per extra scatter. The multiplier tiers jump to x3, x6, x9, and x15 - triple the base game values. A Butterfly wild completing its evolution during a fourth-or-later cascade in free spins is hitting at x15, and the +5 it deposits stacks on top. Landing 2 scatters during the bonus adds 3 more spins, and retriggers are uncapped.
