How does the Worm Trail feature work?

When 4+ caterpillar symbols connect in a chain (horizontally, vertically, or diagonally), the entire trail converts to wilds that remain on the grid for the next spin, creating guaranteed win opportunities.

How does the Harvest Moon bonus work?

Approximately every 30 spins, the full moon rises triggering 10–18 free spins. During this bonus, all caterpillar/worm symbols that land become sticky wilds for the remainder of the round. By the final spins, 15–20+ positions can be wild.
