Mechanics

Three roads to the vault.

Loops are real captures

The Crucible

On reel 5 it collects every magma stone in view — values and jackpots — on any spin it lands.

Real capture · 0:06

Molten Lock

Six or more stones lock in place for three respins that reset with every new stone. A full vault pays the Grand.

Real capture · 0:07

Vault Spins

Three keys open eight spins, retriggerable to 48. Every Crucible raises the molten multiplier ×1 → ×10.

Real capture · 0:07
