Goddess of the Night Bonus Buy Slot by Evoplay

Before free spins begin, a selection screen presents three paths: 6 spins with multipliers reaching x30, 12 spins capping at x15, or 18 spins maxing out at x10. All three cost the same through bonus buy (36x bet), and the base-game trigger is identical for each - three Scatters on reels 1, 3, and 5.

The multiplier progression works differently from most tumble slots. Instead of adding +1 per cascade, it follows fixed steps: x1 on the initial spin, x2 after the first win, x3 after the second, then x5 from the third cascade onward. During free spins, those base values get replaced by the set you chose - so picking the 6-spin option means your first cascade win already applies x12, and a third consecutive cascade jumps to x30.

Wins form left to right across 20 fixed paylines. The tumble mechanic removes winning symbols and drops new ones in from above, with cascades continuing until no new wins appear. The round then resets the multiplier back to x1. Wild symbols land on the middle three reels and substitute for everything except Scatters.

The 38% hit frequency keeps the base game active - roughly one in three spins produces a win. Combined with the tumble mechanic, cascading sequences happen often enough to push multipliers up a couple of steps even outside free spins. The top-paying symbol at five-of-a-kind delivers 125x bet before multipliers apply.
