Wild Unicorns Slot by Big Time Gaming

A Unicorn turns up on every single spin, and where it wanders sets up the whole board. Each one moves in one direction, up, down, left or right, and drops a Wild into every open position along that path, staying off the outer reels 1 and 6 as it goes. Up to three of those planted Wilds carry a multiplier worth as much as x10, and the Wilds stand in for everything except the Scatter. Every win then sets off a reaction: the winning symbols clear out, fresh ones fall from above, and it keeps chaining until nothing more pays.

Scatters only show up on reels 1 and 6. Two of them open 8 free spins, with 4 more tacked on for each Scatter past the second. Every spin inside still guarantees its Unicorn, and a win multiplier starts at x1 and climbs by one after every reaction with no ceiling at all, so a long reacting run through the round is where the maths runs away from you. Land a qualifying win in the base game and don't fancy chasing Scatters? A Win Exchange lets you swap it straight for the free spins. Or buy the feature outright, with Feature Drop symbols on the reels trimming the price and a random enhanced version of the round that can land on a purchase.

The setting is a hushed, sun-dappled woodland, tall trees and ferns and wildflowers washed in soft greens and pinks, more storybook glade than deep forest. The pays are lucky charms: a purple diamond on top, then a red toadstool, a blue horseshoe and a green four-leaf clover, with a rainbow WILD UNICORNS logo strung over the reels. Big Time Gaming built its name on Megaways, but this fairytale grid holds a fixed four-high shape instead, so the 4,096 ways never change count. All the movement comes from wherever the Unicorns decide to walk.
